AcknowledgmentsThis Technical Report was written by Colin Mathers, Gretchen Stevens and Doris Ma Fat with inputs and assistance from Wahyu Retno Mahanani, Jessica Ho and Li Liu. Estimates of regional deaths by cause for years 2000‐2011 were primarily prepared by Colin Mathers, Gretchen Stevens, Jessica Ho, Doris Ma Fat and Wahyu Retno Mahanani, of the Mortality and Burden of Disease Unit in the WHO Department of Health Statistics and Information Systems, in the Health Systems and Innovation Cluster of the World Health Organization (WHO), Geneva, drawing heavily on advice and inputs from other WHO Departments, collaborating United Nations (UN) Agencies, and WHO expert advisory groups and academic collaborators.
Many of the inputs to these estimates result from collaborations with Interagency Groups, expert advisory groups and academic groups. The most important of these include the Interagency Group on Child Mortality Estimation (UN‐IGME), the UN Population Division, the Child Health Epidemiology Reference Group (CHERG), the Maternal Mortality Expert and Interagency Group (MMEIG), the International Agency for Research on Cancer, WHO QUIVER, and the Global Burden of Disease 2010 Study Collaborating Group. While it is not possible to name all those who provided advice, assistance or data, both inside and outside WHO, we would particularly like to note the assistance and inputs provided by Kirill Andreev, Diego Bassani, Bob Black, Ties Boerma, Phillipe Boucher, Freddie Bray, Tony Burton, Harry Campbell, Doris Chou, Richard Cibulskis, Simon Cousens, Jacques Ferlay, Marta Gacic‐Dobo, Richard Garfield, Alison Gemmill, Patrick Gerland, Peter Ghys, Philippe Glaziou, Danan Gu, Ken Hill, Kacem Iaych, Mie Inoue, Robert Jakob, Dean Jamison, Prabhat Jha, Hope Johnson, Joy Lawn, Nan Li, Li Liu, Rafael Lozano, Chris Murray, Lori Newman, Mikkel Oestergaard, Max Parkin, Margie Peden, Francois Pelletier, Juergen Rehm, Igor Rudan, Lale Say, Emily Simons, Charalampos Sismanidis, Thomas Spoorenberg, Karen Stanecki, Peter Strebel, Emi Suzuki, Tamitza Toroyan, Theo Vos, Tessa Wardlaw, Richard White, John Wilmoth and Danzhen You.

1 IntroductionGlobal, regional, and country statistics on population and health indicators are important for assessing development and health progress and for guiding resource allocation. The demand is growing for timely data to monitor progress in health outcomes such as child mortality, maternal mortality, life expectancy and age‐ and cause‐specific mortality rates. Much of the current focus is on monitoring progress towards the targets of the (health‐related) Millennium Development Goals (MDGs), including time series and country‐level estimates that are regularly updated. But increasingly, the demand is for comprehensive estimates across the full spectrum, including noncommunicable diseases (NCDs) and injuries.
WHO has previously published comprehensive estimates of deaths by region, cause, age and sex for years 2000 and 2002 (1), 2001 (2), 2004 (3) and 2008 (4). Beginning with the 2004 estimates, WHO has also released summary estimates of causes of death for its Member States (5). These successive single year estimates did not form a time series, as each revision involved revisions to data and methods for a range of inputs. To address the increasing demand for time series, for country‐level estimates, and for comprehensive estimates across NCD and injury causes, as well as the more traditional priorities in infectious and parasitic diseases, updated Global Health Estimates (GHE) are being released, commencing with regional‐level estimates of deaths by cause, age and sex for years 2000‐2011 (6).
This technical paper documents the data sources and methods used for preparation of these regional‐level cause of death estimates for years 2000‐2011. Annex Table A lists the cause of death categories and their definitions in terms of the International Classification of Diseases, Tenth Revision (ICD‐10) (7). These estimates are available for years 2000 and 2011 for selected regional groupings of countries (6), defined in Annex Tables D, at http://www.who.int/healthinfo/global_health_estimates/en/.
Comprehensive estimates of mortality, causes of death, DALYs for diseases, injuries and risk factors were released in December 2012 (8‐10) by the Institute of Health Metrics and Evaluation (IHME) as part of the Global Burden of Disease 2010 study (GBD 2010). WHO was a collaborator in the study from 2007 to 2011, but did not endorse the final results, as it was unable to obtain full access to the results prior to publication or to evaluate them. In some areas, the results of the GBD 2010 differ substantially from existing analyses done by WHO and other United Nations agencies at global, regional and country levels. In many other areas, the GBD 2010 results are updates that are broadly similar to previous WHO analyses. Further work with IHME and expert groups is needed to examine the reasons for current differences.
One of the six core functions of WHO is monitoring of the health situation, trends and determinants in the world. Over the years it has cooperated closely with other UN partner agencies like UNICEF, UNAIDS, UNFPA and the UN Population Division to collect and compile global health statistics. There are a number of established UN multi‐agency expert group mechanisms for cross cutting topics such as child mortality (the UN‐IGME including UNICEF/WHO/ UNPD/World Bank and the UN‐IGME Technical Advisory Group) and child causes of death (CHERG, WHO/UNICEF), specific diseases such as HIV/AIDS (UNAIDS Reference Group), maternal mortality (MMEIG including WHO/UNICEF/UNFPA/World Bank), tuberculosis (WHO STAG), malaria (Malaria Reference Group and Roll Back Malaria‐ Malaria Monitoring and Evaluation Reference Group).
These WHO Global Health Estimates provide a comprehensive and comparable set of cause of death estimates from year 2000 onwards, consistent with and incorporating UN agency, interagency and WHO estimates for population, births, all‐cause deaths and specific causes of death, including:
o most recent vital registration (VR) data for all countries where the VR data quality is assessed as useable;
WorldHealthOrganization Page2
o updated and additional information on levels and trends for child and adult mortality in many countries without good death registration data
o improvements in methods used for the estimation of causes of child deaths in countries without good death registration data.
o Updated assessments of levels and trends for specific causes of death by WHO programs and interagency groups. These include:
Tuberculosis –WHO
HIV – UNAIDS and WHO
Malaria – WHO
Vaccine‐preventable child causes – WHO
Other major child causes – WHO and CHERG
Maternal mortality –MMEIG
Cancers – IARC
Road traffic accidents – WHO
Conflict and natural disasters – WHO and the Collaborating Center for Research on the Epidemiology of Disasters (CRED)
o GBD 2010 study estimates for other causes in countries without useable VR data or other nationally representative sources of information on causes of death.
Because these estimates draw on new data and on the result of the GBD 2010 study, and there have been substantial revisions to methods for many causes, these estimates for the years 2000‐2011 are not directly comparable with previous WHO estimates for 2008 and earlier years. These are provisional estimates and will be further revised in the process of extending the series to 2012 for release at country level in late 2013. WHO and collaborators will continue to include new data and improve methods, and it is anticipated that some causes will be substantially updated in the next revision.
These Global Health Estimates represent the best estimates of WHO, based on the evidence available to it up until May 2013, rather than the official estimates of Member States, and have not necessarily been endorsed by Member States. They have been computed using standard categories, definitions and methods to ensure cross‐national comparability and may not be the same as official national estimates produced using alternate, potentially equally rigorous methods. The following sections of this document provide explanatory notes on data sources and methods for preparing mortality estimates by cause.

2 Populationandall‐causemortalityestimatesforyears2000‐2011
2.1 All‐causemortalityandpopulationestimatesLife tables have been developed for all Member States for years 1990‐ 2011 starting with a systematic review of all available evidence from surveys, censuses, sample registration systems, population laboratories and vital registration on levels and trends in under‐five and adult mortality rates. Annex table F summarizes the methods used for preparing life tables. Data sources are documented in more detail in Technical Paper 2013.1 (11).
In recent years, WHO has liaised more closely with the UN Population Division (on life tables for countries, in order to maximize the consistency of UN and WHO life tables, and to minimize differences in the use and interpretation of available data on mortality levels. For countries where WHO previously predicted levels of adult mortality from estimated levels of child mortality, this update has taken into account additional country‐specific sources of information on levels of adult mortality as reflected in the life tables prepared by the UN Population Division for its World Population Prospects (WPP).
Total deaths by age and sex were estimated for each country by applying the WHO life table death rates to the estimated de facto resident populations prepared by the UN Population Division in its 2010 revision (12). They may thus differ slightly from official national estimates for corresponding years. All‐cause mortality and deaths by cause will be updated in the next WHO GHE revision to take account of revisions to population estimates included in the WPP 2012 (released mid‐June 2013) (13).
2.2 Estimationofneonatal,infantandunder‐5mortalityratesMethods for estimating time series for neonatal, infant and under‐5 mortality rates have been developed and agreed upon within the Inter‐agency Group for Child Mortality Estimation (UN‐IGME) which is made up of WHO, UNICEF, UN Population Division, World Bank and academic groups. UN‐IGME annually assesses and adjusts all available surveys, censuses and vital registration data, to then estimate the country‐specific trends in under‐five mortality per 1000 live births (U5MR) over the past few decades in order to predict the rates for the reference years (14). All data sources and estimates are documented on the UN‐IGME website.1 For countries with complete recording of child deaths in death registration systems, these are used as the source of data for the estimation of trends in neonatal, infant and child mortality. For countries with incomplete death registration, all other available census and survey data sources, which meet quality criteria, are used. UN‐IGME methods are documented in a series of papers published in a collection in 2012 (15).
For data from civil registration, the neonatal mortality per 1000 live births (NMR) is calculated as the number of neonatal death divided by the live births reported from the country when available. For household surveys, child and neonatal mortality rates are calculated from the full birth history (FBH) data, where women are asked for the date of birth of each of their children, whether the child is still alive, and if not the age at death FBH data, collected by all Demographic Health Surveys (DHS), allow the calculation of child mortality indicators for specific time periods in the past; DHS publishes child mortality estimates for five 5‐year periods before the survey, that is, 0 to 4, 5 to 9, 10 to 14 etc.
A database consisting of pairs of NMRs and U5MRs was compiled. For a given year, NMR and U5MR were included in the database when data for both of these were available. To ensure consistency with
1 www.childmortality.org
WorldHealthOrganization Page4
U5MR estimates produced by UN‐IGME, U5MR and NMR data points were rescaled for all years to match the UN‐IGME estimates.
For countries where child mortality is strongly affected by HIV, the NMR was estimated initially using neonatal and child mortality observations for non‐AIDS deaths, calculated by subtracting from total death rates the estimated HIV death rates in the neonatal and 1‐59 month periods respectively, and then AIDS neonatal deaths be added back on to the non‐HIV neonatal deaths to compute the total estimated neonatal death rate.
The following statistical model was used to estimate NMR:
log(NMR/1000) = α0+ β1*log(U5MR/1000) + β2*([log(U5MR/1000)] 2)
with additional random effect intercept parameters for both country and region. For countries with good vital registration data covering the period 1990‐2011, random effects parameters for slope or trend parameters were also added. Based on predictive performance evaluation using ten‐fold cross‐validation, the statistical model fitted to data point for 1990 onwards were retained and only the most recent data point from each survey was included (16).
2.3 All‐causemortalitycomputedfromcivilregistrationdataFor 133 Member States with vital registration and sample vital registration systems, demographic techniques (such as Brass Growth–Balance method, Generalized Growth–Balance method or Bennett– Horiuchi method) were first applied to assess the level of completeness of recorded mortality data in the population above five years of age and then those mortality rates were adjusted accordingly. The proportion of all deaths which are registered in the population covered by the vital registration system (referred to as completeness) has been estimated by WHO and is given for the latest available years in the annex table.
Where vital registration data for all the reference years were available, the age specific mortality rates, adjusted for completeness if necessary were used directly to construct the life tables. Death registration data up to and including year 2011 were available for 53 Member States.
2.4 All‐causemortalityprojectedfromcivilregistrationdataFor another 60 Member States where vital registration data for 2011 was not available, life table parameters were projected from those for available data years from 1985 onwards. Adjusted levels of child mortality (5q0) and adult mortality (45q15), excluding HIV/AIDS deaths where necessary, were used to estimate levels of two life table parameters (l5, l60) for each available year. The life table parameter l60 was projected forward to 2011 using a weighted regression model giving more weight to recent years (using an exponential weighting scheme such that the weight for each year t was 25% less than the weight for year t+1). For Member States with a total population less than 750,000 or where the root mean square error from this regression was greater than or equal to 0.011, a shorter‐term trend was estimated by applying a weighting factor with 50% annual exponential decay. These projected values of l60, together with values of l5 based on 5q0 from UN‐IGME were then applied to a modified logit life table model, using the most recent national data as the standard, to predict the full life tables in the reference years (17). Where necessary, HIV/AIDS death rates were then added to total mortality rates.
For two small countries without available death registration data, Andorra and Monaco, life tables were based on mortality rates from neighbouring regions of Spain and France, respectively.
WorldHealthOrganization Page5
2.5 CountrieswithotherinformationonlevelsofadultmortalityFor 81 Member States without useable death registration data, assessments of mortality rates for ages 5 and over were based on life table analyses of the UN Population Division (12). The sources of available data used in the WPP are listed elsewhere (18). Annual age‐sex‐specific death rates for years 1990‐2011 were interpolated from the WPP life tables, where necessary first subtracting out conflict and disaster deaths occurring in each specific 5‐year time period. Annual estimates for conflict and disaster deaths were then added back as described below.
For 39 of these Member States, with high levels of HIV mortality, the UN Population Division explicitly estimated HIV deaths in preparing life table time series. For these Member States, HIV‐free mortality rates were computed for interpolation of annual death rates (making use of unpublished supplementary tabulations provided by the UN Population Division for estimated HIV deaths by age and sex in these countries). The latest estimates of annual HIV death rates prepared by UNAIDS (19) were then added back to the annual mortality rates to compute total all‐cause death rates by year. The high‐HIV countries for which this method was used are identified in the Annex Table F.
For six countries, additional data inputs for the most recent period were also taken into account based on provisional analyses for the WPP 2012 provided by the UN Population Division (20). Data sources for these countries are listed in the Annex Table F, and the following notes provide an overview of the analyses used.
Afghanistan
The 2012 revision of child mortality estimates for Afghanistan by UN‐IGME took into account data from the 2010 Afghanistan Mortality Survey (21) and the 2011 UNICEF MICS4 survey (22).
Adjusted estimates of adult mortality (45q15) derived from
recent household deaths data from the 2010 Afghanistan Mortality Survey (AMS);
parental orphanhood from the 2010 AMS (excluding the Southern region);
siblings deaths from the 2010 AMS (excluding the Southern region) adjusted for age
misreporting and recall biases
were also considered, but the implied low level of adult mortality could not be reconciled with intercensal survival between the 1979 Afghan census and 2003‐05 Afghan household listing, or with population estimates from 2003‐05 Household listing and more recent surveys in 2007‐2008 and 2011, or with intercensal estimates of the trends in fertility, and international migration based on UNHCR statistics on the number of Afghan refugees. Additionally, they would imply that Afghan adult mortality levels were substantially lower than those in neighboring countries.
As a result, the life tables for Afghanistan are based on provisional analyses by UN Population Division using the West model of the Coale‐Demeny Model Life Tables with three parameters: (1) estimates of infant mortality, (2) estimates of child mortality, and (3) adjusted estimates of adult mortality (45q15) derived from (a) recent household deaths data from the 1979 census; (b) implied relationship between child mortality and adult mortality based on the UN South Asian and West model of the Coale‐Demeny Model Life Tables, and (c) levels of adult mortality based on sample registration data from neighboring countries for recent years.
WorldHealthOrganization Page6
China
Life tables for years since 2000 have been revised to take into account a faster rate of decline for adult mortality than previously projected in the World Population Prospects 2010 revision. Unpublished analyses of the China 2010 census data on adult mortality by UN Population Division have adjusted for under‐reporting of deaths resulting in estimates of adult mortality rates for 2010 quite similar to those reported by the China Disease Surveillance Points System (23).
Egypt
Life tables have been based on official estimates of life expectancy available through 2012, and in turn derived from death registration data for Egypt. The age pattern of mortality is based on official life tables for various years from 1960 to 2010 adjusted for infant and child mortality as estimated by UN‐IGME, and adult mortality.
Saudi Arabia
The World Population Prospects 2010 revision based estimates of adult mortality for Saudi Arabia using model life tables with estimates of child mortality as input. Estimates of adult mortality have been provisionally updated using adjusted death rates by age and sex from the 1999 Demographic Survey, 2004 Census and 2007 Demographic Survey adjusted for infant and child mortality, and old‐age mortality. Life tables based on annual deaths from the 2000 Demographic Survey, as well as on 2005 and 2009 registered deaths were also considered.
South Sudan and Sudan
The former Sudan became two countries, South Sudan and Sudan, on 9 July 2011. Previously published WHO and UN life tables refer to the former Sudan. Life tables for the two Member States of South Sudan and Sudan are based on provisional analyses of population and mortality rates for the territories corresponding to the current South Sudan and Sudan over the period 1990 to 2011.
Infant and child mortality for South Sudan and Sudan are derived from UN‐IGME estimates published in 2012 (14). Life tables are based on provisional unpublished analyses of the UN Population Division, deriving adult mortality rates from estimates of infant and child mortality by assuming that the age pattern of mortality conforms to the North model of the Coale‐Demeny Model Life Tables. The demographic impacts of AIDS and conflict have also been factored into the mortality estimates.
2.6 Mortalityshocks–epidemics,conflictsanddisastersCountry‐specific estimates of deaths for organized conflicts and major natural disasters were prepared for years 1990‐2011 using data and methods documented in Section 5.12. For country‐years where total death rates from these conflicts and disasters exceeded 1 per 10,000 population, these deaths were added to the life table death rates for the relevant year.
The revised WHO estimates for conflict deaths were taken into account in preparing final life tables for Member States for years 1990‐2011 as follows. For country‐years where death rates from conflict or disasters exceeded 1 per 10,000 population, the estimated annual age‐sex‐specific conflict deaths were added to the life table death rates for the relevant year. In cases of extended conflicts where death rates fluctuated above and below 1 per 10,000, only the death rate in excess of 1 per 10,000 was added to relevant years.
Measles outbreaks and epidemics were identified as described in Section 5.5 below and similarly added to all‐cause envelopes for relevant country‐years.

3 Countrieswithuseabledeathregistrationdata
3.1 DataandestimatesCause‐of‐death statistics are reported to WHO on an annual basis by country, year, cause, age and sex. Most of these statistics can be accessed in the WHO Mortality Database (24). The number of countries reporting data using ICD‐10 has continued to increase. For these estimates, a total of 114 countries had data covering 80% or more of deaths in the country, of which 93 countries were reporting data coded to the third or fourth character of ICD‐10 and 59 countries had data for years 2010 or 2011.
For countries with a high‐quality vital registration system including information on cause of death, we used the vital registration data recorded in the WHO Mortality Database. We analyzed the data using the following steps:
1) application of inclusion criteria to select countries with high‐quality vital registration data;
2) extraction of deaths by cause group, with a short or a detailed cause list used depending on
the ICD revision used in each country‐year;
3) redistribution of deaths of unknown sex/age and deaths assigned to garbage codes and
adjustment for incomplete registration of deaths in some countries;
4) interpolation/extrapolation of number of deaths for missing country‐years;
5) adjustments for certain specific causes using additional information to adjust for over‐ or
under‐reporting
6) scaling of total deaths by age and sex to previously estimated WHO all‐cause envelopes for
years 2000‐2011
Details are provided below.
3.2 InclusioncriteriaforcountrieswithhighqualitydeathregistrationdataWe applied the following inclusion criteria to data in the WHO mortality database:
At least five years of data are available during 1998‐present;
The data are available for 5‐year age groups to ages 85 and over;
The data are for a country whose population in 2008 was greater than 500,000;
The data are for a country that is currently a WHO Member State;
The data fulfill quality criteria pertaining to garbage codes and completeness, as described
below.
For 131 Member States with vital registration systems who have provided summary data to WHO,
demographic techniques (such as Brass Growth–Balance method, Generalized Growth–Balance method
or Bennett– Horiuchi method) were first applied to assess the level of completeness of recorded
mortality data in the population above five years of age. We then calculated the proportion of deaths
with underlying cause coded to a short list of so‐called “garbage” codes:
symptoms, signs and ill‐defined conditions (ICD10 codes R00‐R99),
injuries undetermined whether intentional or unintentional (ICD10 Y10‐Y34, Y87.2),
ill‐defined cancers (C76, C80, and C97), and
ill‐defined cardiovascular diseases ( I47.2, I49.0, I46, I50, I51.4, I51.5, I51.6, I51.9 and I70.9).

A summary usability score was calculated as follows:
(Percent Usable) = Completeness (%) * (1 ‐ Proportion Garbage)
All countries with a mean percent usable below 70% during the period 2000 to latest available year
were excluded (see Table 3.1).
The quality of cause‐of‐death coding was further investigated in the remaining countries. The proportion of deaths assigned to an expanded list of ill‐defined causes (Table 3.2) was calculated for each year in the period 2000‐2011. For the period 2005‐2011 countries had reported an average of 5 years of data. Data from a country were excluded if the average proportion of ill‐defined causes was above 25% for 2005‐2011 (if available) or 2000‐2004 (if more recent data were not available). Based on this analysis, data from Argentina, Azerbaijan, Bulgaria, Greece, Guatemala, Poland, and Qatar were excluded (Table 3.1).

3.3 Redistributionofunknownsex/ageand‘garbage’codesandadjustmentforincompletedeathregistrationFirst, deaths of unknown sex pro‐rata within cause‐age groups of known sexes were redistributed, and then deaths of unknown age pro‐rata within cause‐sex groups of known ages. Deaths coded to garbage codes were reassigned using previously published methods (25). We redistributed deaths coded to symptoms, signs and ill‐defined conditions pro‐rata to all non‐injury causes of death, and injuries with undetermined intent pro‐rata to all injury causes of death. Cancers with unspecified site were redistributed pro‐rata to all sites excluding liver, pancreas, ovary, and lung. Additionally, we redistributed cancer of uterus, part unspecified (C55) pro‐rata to cervix uteri (C53) and corpus uteri (C54). Ill‐defined cardiovascular causes were redistributed to ischaemic heart disease and other cardiovascular causes of death. Finally, the total number of deaths was adjusted for incomplete recording of deaths using the completeness estimates described in Section 3.2.
3.4 MappingtoGHEcauselistsIncluded vital registration data were coded according to ICD9, ICD10, or one of several abbreviated cause lists derived from ICD9 or ICD10. Total deaths by cause, age and sex were mapped to the GHE cause list (Annex Table A). We used the complete cause list in Annex Table A if the data were coded using 3‐ or 4‐digit ICD‐10 codes. In other cases, we extracted the number of deaths by cause, age and sex, using only the broad cause categories listed in Table 3.3. This shortlist in Table 3.3 was used for all data from the Philippines.
For Russia, Belarus and Ukraine, HIV deaths recorded in the death registration data were substantially miscoded to tuberculosis (GHE3), lower respiratory infections (GHE39), other infectious diseases (GHE37), lymphomas and multiple myeloma (GHE76), other malignant neoplasms (GHE78), and endocrine, blood and immune disorders (GHE81). Deaths in these categories falling in the characteristic HIV age pattern were recoded to HIV (GHE10), according to the age‐sex‐specific HIV mortality estimates from UNAIDS (refer Section 5.2).
For countries with deaths data grouped by the shortlist in Table 3.3, shortlist categories were expanded to the full cause list using the cause‐fraction distribution within each shortlist category by year, age, sex and GBD 2010 region from the GBD 2010 study results (26).
Coding of natural causes of death for neonates varies a great deal across countries. Some countries code these deaths to the ‘P chapter’ (conditions originating in the perinatal period) while others use a combination of P codes and other codes as well. In some instances the age of death is not always taken into account. Some conditions, such as septicaemia and pneumonia, have specific codes within P00–P96 which should be used for neonates (0–27 days). For countries with vital registration data, we have recoded all the deaths aged 0–27 days from natural causes that were initially coded outside the ‘P chapter’ to codes in the ‘P chapter’ whenever possible. In a number of countries, neonatal septicaemia (P36) is frequently assigned to A40 and A41 (septicaemia). In this case we have recoded them back to P36, thus identifying more deaths due to causes originating in the perinatal period.

3.5 Interpolationandextrapolationformissingcountry‐yearsFor many countries, data were missing for some years. In order to create a continuous time‐series of data, we interpolated mortality rates for each country and cause, and then extrapolated up to three years of data at the beginning and end of the data series. To interpolate, a logistic regression was fitted for each missing country‐sex‐cause group, using death rates six years prior and six years after the missing data year as the dependent variable and year as the independent variable. In some cases, few deaths were recorded for a specific country‐sex‐cause group and the logistic regression did not converge. In that case, the death rate was estimated as the average rate in the three years prior and three years following the missing data year. To extrapolate for up to three years, a logistic regression was fitted to the first or the final six years of data (including interpolated estimates) for each country‐sex‐cause. Again, if the logistic regression did not converge due to the small number of deaths recorded, the death rate was estimated as the average of the first or last three years’ death rates.
3.6 AdjustmentofspecificcausesEstimates for HIV deaths were compared with UNAIDS/WHO estimates for 46 countries where fewer HIV deaths were recorded in the death registration data than estimated by UNAIDS/WHO (19). UNAIDS/WHO estimates were used except in the cases of Australia, Chile, Costa Rica, France, Trinidad and Tobago, Uruguay and USA.
Estimates for malaria deaths were compared with WHO estimates (see Section 5.3) and replaced by WHO estimates for 63 country years where the WHO estimates were larger than those from the death registration data. This affected malaria deaths for Brazil (12 years), Columbia (10), Venezuela (9), Philippines (8) and Panama (3).
WHO estimates for maternal deaths include an upwards adjustment for under‐recording of maternal deaths in death registration data (27). Maternal deaths were adjusted using these country‐specific factors, and all other causes adjusted pro‐rata.
Deaths due to alcohol and drug use disorders include alcohol and drug poisoning deaths coded to the injury chapter of ICD (see Annex Table A). Further adjustments for under‐reporting in some countries will be undertaken in the next revision of these estimates.
Where necessary, road injury deaths were adjusted upwards to take account of additional surveillance data provided by countries (see Section 5.11).
Estimates of deaths due to conflicts (see Section 5.12) were compared with estimates from the death registration data year by year and added “outside‐the‐envelope” for country‐years where they are not included in death registration data.
3.7 Othernational‐levelinformationoncausesofdeathCause of death estimates for a number of countries drew on non‐national death registration data or other data sources with cause of death information as follows.
China
Cause‐specific mortality data for China were available from two sources – the sample vital registration system data for years 1987 to 2010 (28) and summary deaths tabulations from the Diseases Surveillance Points (DSP) system for years 1995‐1998 and 2004‐2010 (29, 30). Table 3.4 summarizes the deaths and
WorldHealthOrganization Page15
population covered by these two systems. The sample vital registration system data for years 1987 to 2010 was provided in separate tabulations for urban and rural sampled populations, with more urban than rural sampling. The urban and rural crude deaths rates by age, sex and cause were weighted for each year using the UN Population Division’s estimated urban and rural population fractions, and the resulting death rates re‐applied to the UN total estimated population by age and sex. The DSP sample sites are considered to be nationally representative and the resulting total deaths by age, sex and cause were not reweighted. For both sets of data, annual data were rescaled so total deaths by age and sex matched the estimated all‐cause envelopes for China (see Section 2.5).

… data not available.
Both sets of data were assessed and compared for suitability in estimating 2000‐2011 cause‐specific mortality for China at the national level. As seen in Figure 3.1, both sets of data gave quite similar cause distributions at major cause group level by age, across the period 2000‐2010. Additionally, comparison for more detailed major causes of death did not give any clear indication that one data set was of systematically higher quality than the other. We therefore based the update of cause of death estimates for China on an average of the estimates from the two systems.
For all except the leading causes of death, there are considerable fluctuations across 5‐year age groups and year in numbers of deaths, due to stochastic variation and perhaps also variations in recording cause of death from year to year or sample site to sample site. In order to smooth these fluctuations and to estimate underlying trends, cubic spline smoothing was used as follows. For the VR data, cubic spline curves were fitted to age‐sex‐cause specific deaths for years 1987‐2010 using a negative binomial model with population as offset and with knot points at years 1992, 1997, 2003, and 2007. For the DSP data, cubic spline curves were fitted to age‐sex‐cause specific deaths for years 1995‐2010 using a negative binomial model with population as offset and with knot points at years 2004, 2007 and 2010. Final estimates for China were calculated as the average of the fitted spline estimates from VR and DSP for years 2000‐2011.

The resulting cause‐specific estimates were further adjusted with information from WHO technical programmes and UNAIDS on specific causes (see Section 5) and from the GBD 2010 for certain specific subcause categories where deaths were either not recorded or recorded to only selected categories in the DSP and/or VR datasets. GBD 2010 analyses were used for GHE causes 5‐9 (STDs), 20 (hepatitis C), 26 (leishmaniasis), 34‐36 (intestinal nematode infections), 115 (inflammatory heart diseases), and 119 (asthma). Additionally, DSP broad cause group totals were redistributed to detailed subcauses using GBD 2010 cause fractional distributions for the following categories: 82+94 (mental and behavioural disorders and neurological conditions), 134 (musculoskeletal disorders) and 147 (oral conditions). Rabies deaths were revised using data on reported human rabies deaths from the Chinese Center for Disease Control and Prevention (31).
For estimates of causes of death under age 5, a separate analysis was undertaken based on an analysis of 206 Chinese community‐based longitudinal studies that reported multiple causes of child death (see Section 4.5 below. The CHERG conducted a systematic search of publically available Chinese databases in collaboration with researchers from Peking University. Information was obtained from the Chinese Ministry of Health and Bureau of Statistics websites, Chinese National Knowledge Infrastructure (CNKI) database and Chinese Health Statistics Yearbooks published between 1990‐2008. A model was developed to assign the total number of child deaths to provinces, age groups and main causes of child death.

India
Analysis of causes of death for India was based on data over a period of 3 years (2001–2003) recorded by the Million Death Study (32,33), a comprehensive study based on verbal autopsy that assigned causes to all deaths in areas of India covered by the Sample Registration System. The Sample Registration System monitors a representative sample population of 6.3 million people in over 1 million homes in India. The 1991 census was used to randomly select 6671 areas from approximately 1 million having about 1000 inhabitants in each.
In 2001 the Indian Registrar General Surveyor introduced an enhanced form of verbal autopsy for assessing the cause of death. Verbal autopsy is a method of ascertaining the cause of death by interviewing a family member or caretaker of the deceased to obtain information on the clinical signs, symptoms and general circumstances that preceded the death. Details of methods and validation have been reported elsewhere (33). Verbal autopsy reports were independently coded to ICD‐10 categories by at least two of a total of 130 physicians trained in ICD‐10 coding. In case of disagreement on the ICD‐10 codes at the chapter level, reconciliation between reports was conducted, followed by a third senior physician’s adjudication.
A total of 136,000 deaths were enumerated between January 2001 and December 2003. Verbal autopsies could not be conducted for 12% of the deaths for reasons such as family migration or change of residence. An additional 9% of the reports could not be coded because of data quality problems, resulting a final dataset of 122,848 coded records.
The cause‐specific proportion of deaths in each five‐year age category from 0 to 79 years and for people aged 80 years and over was weighted by the inverse probability of a household being selected within rural and urban subdivisions of each state to account for the sampling design. National estimates for deaths and mortality rates were based on United Nations 2005 estimates for India, by age, sex and area.

The GHE analysis is based on the resulting national‐level cause‐specific mortality proportions derived for GHE cause categories from the Million Death Study. The mapping of the MDS cause categories to GHE cause categories, and the use of GBD 2010 analyses to redistribute deaths to detailed subcause categories is summarized in Annex Table E. GHE cause categories 26 (leishmaniasis) and 124 (appendicitis) were also estimated using GBD 2010 results.
The resulting cause‐specific estimates were further adjusted with information from WHO technical programmes and UNAIDS on specific causes (see Section 5) and adjusted to match WHO estimates of age‐sex specific all‐cause mortality for India in 2002. Cause‐specific trends for India estimated in the GBD 2010 study (26) were used to project cause‐fractions forwards to 2011 and backwards to 2000.
Figure 3.2 provides a comparison of the final proportional distributional estimates of deaths by cause and age for India in the year 2002 with the original distributions in the Million Death Study for 2001‐2003.

4 Childmortalitybycause Cause‐specific estimates of deaths for children under age 5 were estimated for 17 cause categories using methods described elsewhere by Liu et al. (34) and on the WHO website (35). These previously published estimates for years 2000‐2010 were updated to take account of revisions in child mortality levels (14), as well as cause‐specific estimates for HIV, tuberculosis, measles and malaria deaths (as described in Section 5). Inputs to the multivariate cause composition models were also updated as described below.
4.1 Causesofunder5deathincountrieswithgooddeathregistrationdataDeath registration data were used directly for estimating causes of neonatal and under 5 child deaths for countries with good quality vital registration (VR) data with population coverage of >80%. VR data were considered as of good quality if the following criteria were met: (a) reasonable distribution of deaths by cause were reported without excessive use of implausible codes or certain codes, and (b) sufficient details of the coding was provided so that deaths could be grouped into appropriate categories used in the analysis. For countries with adequate death registration, data on causes of child deaths were extracted from the WHO mortality database, adjusted for coverage incompleteness where needed, and grouped according to the standard International Classification of Diseases, 10th revision (ICD‐10). For earlier years when ICD‐9 codes were used, a mapping system was applied to convert them into ICD‐10 codes (34,webappendix). Certain neonatal codes were re‐assigned from ill‐defined codes to more plausible codes (see Annex Table C). Annual data for years 2000 to the latest available year were included with data closest to the estimating year used where possible. Where the latest year available was earlier than 2011, the cause distribution for the latest available year was assumed to apply for subsequent year(s), which was then applied to the age‐specific total number of child deaths.
4.2 Causesofneonataldeath(deathsatlessthan28daysofage)The CHERG neonatal working group undertook an extensive exercise to derive mortality estimates for six causes of neonatal death, including preterm birth, asphyxia, severe infection, diarrhoea, congenital malformation and other causes (36). These cause categories are defined in Annex Table B.
Death registration data were used directly for 61 countries considered to have reliable information. For another 51 low mortality countries, the cause distribution was estimated using a multinomial model applied to death registration data. For 80 high mortality countries the cause distribution was estimated using a multinomial model applied to (largely) verbal autopsy (VA) data from research studies (34). A total of 90 studies in 34 countries in high mortality populations met the inclusion criteria. The multinomial model for high mortality countries was generally used for countries with average U5MR>35 for the period 2000‐2010.
A separate cause category for neonatal pneumonia is included in the model, and the neonatal sepsis category includes a number of neonatal infections, such as meningitis and tetanus, not separately identified. The number of tetanus deaths was also modeled separately in a single cause model using using a logistic regression model with percent of women who were literate, percent of births with skilled attendant, and percent protected at birth by tetanus toxoid vaccine as covariates. The resulting cause‐specific inputs were adjusted country‐by‐country to fit the estimated neonatal death envelopes for corresponding years.
Pending further revisions of the neonatal tetanus model to estimate longer‐term trends in neonatal tetanus deaths, estimates for 2011 and 2000 were based on projection and back‐projection of the 2008 estimates using estimates of trends in tetanus deaths from the GBD 2010 study (26).

4.3 Causesofchilddeathatages1‐59months–lowmortalitycountriesFor 51 low mortality countries without VR data or with VR data not meeting quality criteria (see Section 4.1), the cause distribution was estimated using a multinomial model applied to death registration data. This multinomial model applied to death registration data was generally used for countries with average U5MR<35 for the period 2000‐2010.
For the estimates for years 2000‐2011, the previous vital registration‐based multicause model (VRMCM) model was revised to include additional death registration data and to update time series for covariates and extend them to 2011. The choice of covariates included in the model was not revisited for this regional‐level update. The multinomial logistic regression model was estimated using death registration data from countries with >80% complete cause of death (CoD) certification for years 1990‐2011 to estimate the proportion of deaths due to pneumonia, diarrhea, meningitis, injuries, perinatal, congenital anomalies, other NCDs and other causes.
The current version of the model used death registration data for the years 1990 to 2011, including 1,123 data points, representing 63 countries. The model included the following covariates that were determined a priori: U5MRs, GNI per capita (PPP, $international), WHO European and American regions. Adjustments for the scaling‐up of Hib vaccine occurred within the model. The proportional distribution of causes of death was then applied to the HIV‐free and measles‐free envelope for children 1‐59 months of age. Jack‐knife and Monte Carlo simulation methods were used to estimate uncertainty.
4.4 Causesofchilddeathatages1‐59months–highmortalitycountriesFor 79 high mortality countries (average U5MR>35 for the period 2000‐2010), the cause distribution was estimated using a multinomial model applied to (largely) verbal autopsy (VA) data from research studies (34,36,37). The multicause model for deaths at ages 1‐59 months was used to derive mortality estimates for seven causes of postneonatal death, including pneumonia, diarrhea, malaria, meningitis, injuries, congenital malformations, causes arising in the perinatal period (prematurity, birth asphyxia and trauma, sepsis and other conditions of the newborn), and other causes, based on 113 data points from 74 studies of postneonatal deaths from 33 countries that met inclusion criteria2. Studies were predominantly from lower income high mortality countries. Malnutrition deaths were included in the other cause of death category. Deaths due to unknown causes were excluded from the analysis. Deaths due to measles and HIV/AIDS were estimated separately.
The resulting cause‐specific inputs were adjusted country‐by‐country to fit the estimated 1‐59 month death envelopes (excluding HIV and measles deaths) for corresponding years and then estimates were further adjusted for intervention coverage (pneumonia and meningitis estimates adjusted for use of Hib vaccine; malaria estimates adjusted for insecticide treated mosquito nets (ITNs)). This method was used for countries without useable death registration data and with U5MR>26 and gross national income per capita less than $7,510.
2 Studies conducted in year 1980 or later, a multiple of 12 months in study duration, cause of death available for more than a single cause, with at least 25 deaths in children <5 years of age, each death represented once, and less than 25% of deaths due to unknown causes were included. Studies conducted in sub-groups of the study population (e.g. intervention groups in clinical trials) and verbal autopsy studies conducted without use of a standardized questionnaire or the methods could not be confirmed were excluded from the analysis.

4.5 CausesofchilddeathforChinaandIndiaIn order to estimate trends in under 5 causes of death for India, the previously developed subnational analyses were further refined and used to develop national estimates for years 2000‐2011 (38). For neonates, a verbal autopsy multi‐cause model (VAMCM) based on 37 sub‐national Indian community‐based VA studies was used to predict the cause distribution of deaths at state level. The resulting cause‐specific proportions were applied to the estimated total number of neonatal deaths to obtain the estimated number of deaths by cause at state level prior to summing to obtain national estimates.
For children who died in the ages of 1‐59 months in India, the previously developed multicause model was rerun for years 2000‐2011 using a total of 23 sub‐national community‐based VA studies plus 22 sets of observations for the Indian states derived from the Million Death Study (39). Nine cause categories were specified, including measles plus the eight specified in the post‐neonatal VAMCM for other countries. State‐level measles deaths were then normalized to fit the national measles estimates produced by the WHO IVB. State‐level AIDS and malaria estimates were provided by UNAIDS and WHO malaria program, respectively. All cause fractions were adjusted to sum to one. The state‐level estimates were collapsed to obtain national estimates at the end.
For China, updated IGME U5MR estimates in 2000‐2011 were applied to the VA‐based national cause‐specific models developed by Rudan and colleagues (40) to derive cause‐fractions annually in this period. Together with cause‐specific inputs from WHO technical programmes and UNAIDS for measles, meningitis, malaria and AIDS, the resulting cause‐specific inputs for China were adjusted to fit the estimated total deaths at ages 0‐1 month and 1‐59 months, respectively.
4.6 Inclusion ofWHO‐CHERG estimates in Global Health Estimates 2000‐2011The seventeen cause categories used for the WHO‐CHERG estimates of under 5 deaths for years 2000‐2011 (see Annex Table B) include all the major causes of neonatal, postneonatal and 1‐4 year deaths and two residual categories containing all remaining causes of death. These residual categories (“Other Group 1” and “Other Group 2”) and cause groups such as “Congenital malformations” and “Injuries” were expanded to the full GHE cause list (Annex Table A) for neonatal and under 5 deaths using cause distributions derived from VR data for countries with useable VR data (see Annex Table F) and from the GBD 2010 estimates for other countries (26).

5 Methodsforspecificcauseswithadditionalinformation
5.1 TuberculosisFor countries with death registration data, tuberculosis mortality estimates were generally based on the most recently available vital registration data. For other countries, total tuberculosis deaths were derived from latest published WHO estimates (41), together with more detailed unpublished age distributions based on the VR data and notifications data.
5.2 HIV/AIDSandsexuallytransmitteddiseasesFor countries with death registration data, HIV/AIDS mortality estimates were generally based on the most recently available vital registration data except where there was evidence of misclassification of HIV/AIDS deaths. In such cases, a time series analysis of causes where there was likely misclassified HIV/AIDS deaths was carried out to identify and re‐assign such deaths. For other countries, estimates were based on UNAIDS estimated HIV/AIDS mortality (19). It was assumed based on advice from UNAIDS that 1% of HIV deaths under age 5 occurred in the neonatal period.
5.3 Malaria Countries outside the WHO African Region and low transmission countries in Africa3.
Estimates of the number of cases were made by adjusting the number of reported malaria cases for completeness of reporting, the likelihood that cases are parasite‐positive and the extent of health service use. The procedure, which is described in the World Malaria Report 2012 (42), combines data reported by National Malaria Control Programs (reported cases, reporting completeness, likelihood that cases are parasite positive) with those obtained from nationally representative household surveys on health service use. If data from more than one household survey was available for a country, estimates of health service use for intervening years were imputed by linear regression. If only one household survey was available then health service use was assumed to remain constant over time; analysis summarized in the World Malaria Report 2008 (43) indicated that the percentage of fever cases seeking treatment in public sector facilities varies little over time in countries with multiple surveys. Such a procedure results in an estimate with wide uncertainty intervals around the point estimate.
The number of deaths was estimated by multiplying the estimated number of P. falciparum malaria cases by a fixed case fatality rate for each country as described in the World Malaria Report 2012 (42). This method is used for all countries outside the African Region and for countries within the African Region where estimates of case incidence were derived from routine reporting systems and where malaria causes less than 5% of all deaths in children under 5. A case fatality rate of 0·45% is applied to the estimated number of P. falciparum cases for countries in the African Region and a case fatality rate of 0·3% for P. falciparum cases in other Regions. In situations where the fraction of all deaths due to malaria is small, the use of a case fatality rate in conjunction with estimates of case incidence was considered to provide a better guide to the levels of malaria mortality than attempts to estimate the fraction of deaths due to malaria.
Somalia, Sudan and high transmission countries in the WHO African Region.
Child malaria deaths were estimated using the VAMCM described in Section 4.4. The VAMCM derives mortality estimates for malaria, as well as 7 other causes (pneumonia, diarrhea, congenital
3 Botswana, Cape Verde, Eritrea, Madagascar, Namibia, Swaziland, South Africa, and Zimbabwe
WorldHealthOrganization Page23
malformation, causes arising in the perinatal period, injury, meningitis, and other causes) using multinomial logistic regression methods to ensure that all 8 causes are estimated simultaneously with the total cause fraction summing to 1. Malaria deaths were retrospectively adjusted for coverage of insecticide‐treated nets (ITNs) and use of Haemophilus influenzae type b vaccine (34). The bootstrap method was employed to estimate uncertainty intervals by re‐sampling from the study‐level data to estimate the distribution of the predicted percent of deaths due to each cause. The estimated malaria mortality rate in children under 5 years for a country was used to determine malaria transmission intensity and the corresponding malaria‐specific mortality rates in older age groups (43).
5.4 WhoopingcoughAn updated model of whooping cough (pertussis) mortality is being developed by the WHO Department of Immunization, Vaccines and Biologicals (IVB). This model has not been finalized in time for the release of these regional‐level estimates but will be used to update the GHE estimates at country level later in 2013. In the interim, whooping cough mortality estimates from the GBD 2010 (26) have been used as an input to the WHO‐CHERG analysis of child causes of death under age five (see Section 4).
5.5 MeaslesTo estimate deaths attributable to measles, a new model of measles mortality developed by WHO Department of Immunization, Vaccines and Biologicals (IVB) was used to first estimate country‐and‐year‐specific cases using surveillance data (44). The improved statistical model firstly estimates measles cases by country and year using surveillance data and making explicit projections about dynamic transitions over time as well as overall patterns in incidence.
The age distribution of measles cases are then estimated using a logistic regression function fitted to 172,191 measles cases with data on age at infection from 102 countries over 2005‐2009 extracted from WHO's monthly measles case‐based reporting system. Two explanatory variables were included in the regression: 1) the 5 year rolling average of estimated MCV1 coverage, categorized in <60%, 60‐84%, and 85‐100%; and 2) geographic region classified in to 7 groups.
Country‐specific measles case‐fatality ratios (CFRs) for children 1‐4 years of age were taken from a comprehensive review of community‐based studies (45). This review included 102 field studies conducted in 29 countries during the period 1974‐2007. The set of CFRs were revised for two countries (India and Nepal) where additional studies have been published subsequent to the review (46, 47). The same CFRs were used for infants and for children aged 1‐4 years. For the period 2000‐2011, we assumed that age‐specific CFRs are not declining over time.
Age‐specific deaths are aggregated to derive measles deaths for all children below five and for ages five and over. The new method takes into account herd immunity and produces results that are fairly consistent with previous ones (48). Uncertainty is estimated by bootstrap sampling from the distribution of incidence and age distribution estimates. Updated estimates of measles deaths by age and country for years 2000‐2011 were prepared using the above methods at the end of 2012 and summary results published in the Weekly Epidemiological Record (49).These were used for this update of GHE causes of death for years 2000‐2011.
For countries experiencing measles outbreaks, the measles deaths were split into outbreak and endemic deaths, the latter of which were smoothed using local regression (50). For the ages of 1‐59 months, the endemic measles deaths and AIDS deaths were added to the measles‐ and AIDS‐free all‐cause deaths for which the VAMCM derived cause fractions were applied. The measles outbreak deaths were added back at the end. In places where the outbreak deaths resulted in an increase in the all‐cause deaths by 10% or
WorldHealthOrganization Page24
more, the original survey data were screened to examine whether a real increase in child mortality was indicated for the outbreak year. If there were survey data available for the years around the outbreak but no evidence of an increased mortality, the measles outbreak deaths were truncated at 10% of the all‐cause deaths. This was only necessary in few countries, almost all of which are in Africa and all occurred in the early 2000s when more measles deaths were estimated.
5.6 SchistosomiasisFor the last WHO update of burden of disease for year 2004 (3), the incidence and prevalence of cases of schistosomiasis infection were separately estimated by country for S. mansoni, S. haematobium and S. japonicum plus S. mekongi. The GBD 2004 estimated that schistosomiasis was responsible for around 41 000 deaths globally (excluding attributable cancer deaths) and 36 000 in sub‐Saharan Africa, although others have argued that the figure should be much higher (51). Van der Werf et al (52), using limited data from Africa, estimated that schistosomiasis caused 210 000 deaths annually. For the GBD 2004 update (3), very limited available data was used to conservatively estimate annual case fatality rates for prevalent cases at 0.01% for S. mansoni, 0.02% for S. haematobium, and 0.03% for S. japonicum and S. mekongi. There were estimated to be 261 million prevalent cases of schistosomiasis infection in 2004.
The GBD 2010 study estimated that there 11,650 deaths due to schistosomias in 2010, of which 1,813 were in the Middle East and North Africa, and only 61 in sub‐Saharan Africa in 2010. Divided by the numbers of prevalent cases estimated by the GBD 2010, the implied case fatality rates for the Middle East and North Africa, and for Latin America are 0.01% and 0.02% respectively. In comparison, the implied African case fatality rate is almost 400 times smaller. Implied case fatality rates for non‐African regions in the GBD 2010 were generally consistent with those previously estimated by WHO for the year 2004. Revised case fatality rates of 0.0075% for S. mansoni, 0.015% for S. haematobium were applied to the prevalence rates estimated by GBD 2010 (53) to revise the estimates of schistosomiasis deaths for GHE. This resulted in an estimate of 17,600 deaths in sub‐Saharan Africa and 23,300 deaths globally in 2011.
5.7 MaternalcausesofdeathCountry‐specific estimates for maternal mortality were based on the recent Interagency estimates for years 2000‐2011 (27,54). For 62 Member States with relatively complete data from national death registration systems, these data were used directly for estimating and projecting maternal mortality ratios. For other Member States, a multilevel regression model was developed using available national‐level data from surveys, censuses, surveillance systems and death registration. This regression model included national income per capita, the general fertility rate and the presence of a skilled attendant at birth (as a proportion of total births) as covariates to predict trends in maternal mortality.
Note that numbers of maternal deaths were adjusted upwards by a country‐specific fraction, or by 50%, for countries with useable death registration data but without country‐specific data on misclassification of maternal deaths, to allow for under‐identification of maternal deaths. Note also that the maternal mortality estimates include those HIV deaths occurring in pregnant women or within 42 days of end of pregnancy which were considered to be indirect maternal deaths rather than incidental. These HIV maternal deaths were subtracted from total HIV deaths as estimated by UNAIDS.
5.8 CancersCause‐specific estimates for cancer deaths were derived from Globocan 2008 (55) for countries without useable death registration data. Site‐specific deaths were projected back to year 2000 and forwards to year 2011 using trend estimates from the GBD 2010 (26).
WorldHealthOrganization Page25
Karposi sarcoma was excluded from the Globocan estimates as this is almost entirely a manifestation of HIV/AIDS, already included in the estimates for HIV/AIDS deaths. Deaths due to non‐melanoma skin cancers were included in these estimates along with melanoma, unlike in Globocan 2008.
5.9 AlcoholuseanddrugusedisordersThe injury codes for accidental poisoning by alcohol and by opioids are now used to code acute intoxication deaths from alcohol and acute overdose deaths by opioids. These deaths have been remapped to alcohol use disorders and drug use disorders respectively (see Annex Table A). WHO estimates of direct deaths associated with alcohol use disorders and total deaths attributable to alcohol consumption are under revision for a forthcoming report. The interim estimates included here for alcohol use disorders will be revised in the next revision to take these updates into account.
GBD 2010 estimates of deaths due to drug use disorders were revised to correct an extremely low implied case fatality rate for opioid dependent drug users in South Asia and for consistency with estimates of prevalence and mortality associated use of illicit opiate drugs reported by the UN Office on Drugs and Crime (UNODC) (56). UNODC estimated that there were around 17 million opiate users globally in 2010, with higher than average prevalence of opioid users in North America, Oceania, Eastern Europe and South East Europe. These estimates were quite similar to those of the IHME‐GBD 2010, which estimated a global prevalence of 17.3 million for opioid dependence in 2010 (53). The IHME‐GBD 2010 estimated a total of 77,615 deaths for drug use disorders in 2010, of which 43,000 were for opioid use disorders. The implied case fatality rate of opioid use was 0.25% globally, 0.23% in the Middle East and North Africa, and just under 0.1% in East and South East Asia. In contrast, the implied case fatality rate of 0.025% in South Asia was only 1/10th of the global average. Estimated opioid dependence deaths were conservatively revised upwards for South Asia to give an implied case fatality rate similar to that of the other Asian regions. The resulting GHE estimate of 91,900 deaths for all drug use disorders in 2011 is similar to the UNODC estimate of around 100,000 total direct drug use deaths in 2010 (with an additional 100,000 deaths from other causes, such as infectious diseases, also attributable to drug use disorders).
5.10 EpilepsyThe Million Death Study for India (32,33) recorded relatively high proportions of epilepsy deaths, resulting in an initial GHE estimate of 73,600 epilepsy deaths in India in 2010 compared to an estimated 21, 650 by the GBD 2010. GBD 2010 estimates of untreated idiopathic epilepsy prevalence were used to calculate implied regional case fatality rates (CFR) and the implied Indian CFR of 0.34 was substantially higher than those for South East Asia (0.09) or the Middle East and North Africa (0.05). Indian epilepsy deaths were adjusted downwards to give an implied case fatality rate of 0.17 (close to the global average), resulting in an estimated 35,480 epilepsy deaths for India in 2010.
5.11 RoadinjuriesFor the second WHO Global status report on road safety (57), updated estimates of road injury deaths were prepared for 182 Member States for the year 2010. These estimates drew on death registration data, on reported road traffic deaths from official road traffic surveillance systems (collected in a WHO survey of Member States for the report), and on a revised regression model for countries without useable death registration data. The same methods were used to develop time series estimates of road injury deaths for years 2000‐2011 for all Member States.
The methods used for four groups of countries are summarized below and the method used for each country is documented in Annex Table G.
WorldHealthOrganization Page26
5.11.1Countrieswithdeathregistrationdata
This group includes 87 countries with death registration data meeting one of the following completeness criteria, viz. completeness for the year estimated at 80% or more, or average completeness for the decade including the country‐year was 80% or more.
These countries fell into three categories:
1. For countries with death registration data for the year 2010 which exceeded the number of road traffic deaths reported in the survey – death registration data was used. There were 33 countries in this category.
2. For countries where the latest death registration data submitted to WHO was earlier than 2010, but not earlier than 2005 – deaths for 2010 were estimated based on a projection of the most recent death registration data using the trends obtained through the survey. There were 40 countries in this category.
3. For countries where the reported road traffic deaths for 2010 obtained through the survey exceeded the estimate based on death registration data: The reported road traffic deaths (adjusted to the 1 year definition) were used. There were 12 countries in this category. There were an additional 2 countries where reported data for earlier years were projected to 2010 and used because they exceeded the death registration numbers.
5.11.2Countrieswithothersourcesofinformationoncausesofdeath
For India, Iran, Thailand and Viet Nam, data on total deaths by cause were available for a single year or an earlier recent single year or group of years (33,58‐60). For these countries, the regression method described below was used to project forward from the most recent year for which an estimate of total road traffic deaths were available.
5.11.3Countrieswithpopulationslessthan150000
For 13 small countries with populations of less than 150 000 people the deaths reported in the survey were used directly without adjustment.
5.11.4Countrieswithouteligibledeathregistrationdata
For 78 countries which did not fall into any of the above groups, a regression model was used to estimate total road traffic deaths. The regression model produced estimates of total road traffic deaths according to the accepted International Classification of Disease definition, which counts all deaths that follow from a road traffic death, regardless of the time period in which they occur (unlike many official road traffic surveillance data sources, where road traffic death data is based on a 30‐day definition following a road traffic crash). Where total deaths reported by Member States surveillance systems were greater than the deaths estimated from the regression, these were used.
Three classes of models were tested and a negative binomial counts model was chosen:
PopXXXCN nn ln....ln 2211 (1)
where N is the total road traffic deaths (for a country‐year), C is a constant term, Xi are a set of explanatory covariates, Pop is the population for the country‐year, included as an offset, and ε is the negative binomial error term. This model was estimated using death registration data for the period 1950–2010 that were 80% or more complete for a given year or where the average completeness for
WorldHealthOrganization Page27
the last decade was greater or equal to 80%. It also included nationally representative verbal autopsy or sample death registration data for India, China and Vietnam.
Three models (A, B and C) were chosen that had good in‐sample‐ and out‐of‐sample fit, and for which all the covariates (see Table 5.1) were statistically significant at the 95% level. The final estimates were based on the average predictions of these three best models.
Age distributions for road injury deaths were based on regional age distributions estimated in the GBD 2010 study (26).

5.12 ConflictandnaturaldisastersEstimated deaths for major natural disasters were obtained from the CRED International Disaster Database (64). For country‐years where disaster death rates exceeded 1 per 10,000 population, these deaths were added to the life table death rates for the relevant year. Age‐sex distributions were based on a number of studies of earthquake deaths (65,66) and tsunami deaths (67,68).
Country‐specific estimates of war and conflict deaths were updated for the entire period 1990‐2011 using revised methods together with information on conflict intensity, time trends, and mortality obtained from a number of war mortality databases (described below). These estimates relate to deaths for which the underlying cause (following ICD conventions) was an injury due to war, civil insurrection or organized conflict, whether or not that injury occurred during the time of war or after cessation of hostilities. The estimates include injury deaths resulting from all organized conflicts, including organized terrorist groups, whether or not a national government was involved. They do not include deaths from other causes (such as starvation, infectious disease epidemics, lack of medical intervention for chronic diseases), which may be counterfactually attributable to war or civil conflict.
Methods used previously by WHO for estimation of direct conflict deaths were developed in the early 2000s and applied adjustment factors for under‐reporting to estimates of battlefield or conflict deaths from a variety of published and unpublished conflict mortality databases (69‐72). Murray et al. (73) summarized the issues with estimation of war deaths, and emphasized the very considerable uncertainty in the original Global Burden of Disease estimates (74) and subsequent WHO estimates for conflict deaths. WHO published estimates for the years 2000 through 2008 used adjustment factors based on conflict intensity developed from an analysis of likely levels of under‐reporting (1‐4). These adjustment factors ranged from around 3 to higher than 4 in sub‐Saharan Africa.
Obermeyer, Murray and Gakidou (75) more recently analyzed data on deaths due to conflict from post‐conflict sibling histories collected in the 2002 to 2003 WHO World Health Survey (WHS) program. They used data from 13 countries with more than 5 reported sibling deaths from war injuries in at least one 10‐year period to estimate total war deaths for these countries for the period 1955‐2002. The authors then compared their estimates of war deaths to the number of war deaths estimated in the UCDP Battle Deaths database (76) to derive an average adjustment factor of 2.96. Garfield and Blore (77) noted that a very small number of war deaths for Georgia resulted in an outlier ratio of 12.0 which heavily influenced the overall ratio of 2.96. They reanalyzed the WHS‐derived war deaths dataset excluding Georgia, to obtain an overall revised adjustment factor of 2.21.
The revised WHO country‐specific estimates of war and conflict deaths for the period 1990‐2011 make use of estimates of direct deaths from three datasets: Battle‐Related Deaths (version 5), Non‐State Conflict Dataset (UCDP version 2.4), and One‐sided Violence Dataset (UCDP version 1.4) from 1989 to 2011 (78‐80). Using these three datasets, instead of focusing solely on battle‐related deaths, reduces the likelihood that overall direct conflict deaths are underestimated. However, it likely that a degree of undercounting still occurs in the count‐based datasets, and the adjusted ratio obtained by Garfield and Blore (77) of 2.21 is applied to the annual battle death main estimates for state‐state conflicts (78). No adjustments were applied to estimated conflict deaths (main estimates) for non‐state conflict deaths (79), and one‐sided violence (80).
Additional information from epidemiological studies and surveys was also used for Iraq (81,82). Deaths due to landmines and unexploded ordinance were estimated separately by country (83). Age‐sex distributions for conflict deaths were revised based on available distributions of conflict deaths by age and sex for specific conflicts (73,75,81‐86).
The following tables summarizes and compares various time series of conflict deaths estimates.

The revised WHO estimates for total conflict deaths (in the column WHO 2013) are considerably lower than the previous WHO estimates for years 2000‐2008 which used the earlier higher adjustment factor for under‐reporting, which in turn are lower than the previous estimates and projections in the original GBD study (74). The recently estimates for conflict deaths published by IHME in the GBD 2010 study, shown in the rightmost column, are considerable lower than the revised WHO estimates. For the year 2010, the IHME estimates are also lower than the main estimate from the UCDC‐PRIO databases for the same year. The IHME methods were based on a regression analysis of available all‐cause mortality data for country‐years in which battle deaths were reported in various databases. Lozano et al (26) cite (90) for more detailed documentation of their methods.
The revised WHO estimates for conflict deaths were taken into account in preparing final all‐cause mortality envelopes for Member States for years 1990‐2011 as follows. For country‐years where death rates from conflict or disasters exceeded 1 per 10,000 population, the estimated annual age‐sex‐specific conflict deaths were added to the life table death rates for the relevant year. In cases of extended conflicts where death rates fluctuated above and below 1 per 10,000, only the death rate in excess of 1 per 10,000 was added to relevant years.

6 OthercausesofdeathforcountrieswithoutuseabledataPrevious WHO comprehensive estimates of causes of death have relied on cause‐of‐death modelling and available data on cause of death distributions within each analysis subregion to estimate causes of death for countries without useable data and where WHO cause‐specific analyses were not available (2, 3). The IHME developed covariate based estimation models for a large number of single causes as inputs to its overall estimation of numbers of deaths by country, cause, age and sex for years 1990‐2010 in the GBD 2010 study (8‐10). Results from these models are used as inputs to WHO Global Health Estimates for causes of death not addressed by WHO and UN Interagency estimation processes and where countries did not have useable death registration data, as described below.
Six different modelling strategies were used by IHME for causes of death depending on the availability of data (26,webappendix). For all major causes of death except HIV/AIDS and measles, IHME used ensemble modelling to create a weighted average of many individual covariate‐based models (ranging from hundreds to thousands in some cases) for each specific cause (26,91). IHME cause of death estimation methods are thus complex and highly computer‐intensive. The overall out‐of‐sample predictive validity of the ensemble is usually not much different to that of the top‐ranked model, but uncertainty ranges are generally much wider and more plausible than for single models.
IHME results for priority causes such as HIV, TB, malaria, cancers, maternal mortality, child mortality differ to varying degrees from those of WHO and UN agency partners. In part, this reflects differences in modelling strategies, but also the inclusion by IHME of data from verbal autopsy (VA) studies which has been mapped to ICD categories using IHME‐developed computer algorithms. WHO aims to work with IHME and expert groups to further improve data and methods, which requires that all input data and detailed analysis methods and results are made available. Figure 6.1 provides a comparison of major cause group death rates for the GBD 2010 and WHO GHE results for year 2010 for seven broad regional groupings.
To ensure that the results of all the single‐cause models summed to the all‐cause mortality estimate for each age‐sex‐country‐year group, IHME applied a final step called CoDCorrect to rescale the cause‐specific estimates. This was done using repeated random draws from the uncertainty distributions of each single cause and from the all‐cause envelope, and proportionately rescaling each single cause estimate so they collectively summed to the envelope estimate. The overall effect is to “squeeze” or “expand” causes with wider uncertainty ranges more than those with narrower uncertainty ranges.
GBD 2010 results, post‐CoDCorrect, were used as inputs to estimate cause fractions by country, age, sex and year for causes of death at ages five years and above for which death registration data and/or WHO and UN Interagency analyses (described in Section 5) were not available. For this set of causes, GBD 2010 country‐level estimates for death rates at ages 5 and over for years 1990, 1995, 2000, 2005 and 2010 were interpolated to death rates for all years in the range 2000‐2011 using cubic spline interpolation of log(death rates. Cause fraction distributions were then computed for the set of causes excluding WHO/Interagency cause‐specific estimates. For countries where these cause fractions were used (see Annex Table G), they were applied to the country‐level residual mortality envelopes by age and sex after the WHO/Interagency cause‐specific estimates were subtracted from the WHO all‐cause envelopes.
Table 6.1 summarizes the overall percentage change in the GBD 2010 estimates for each of these residual causes resulting from the above process. This provides a rough metric of how much inconsistency there is between the GBD 2010 and the GHE 2010 estimates for ages five and over as a result of differences in all‐cause envelopes and WHO/Interagency estimates for specific causes.

7 UncertaintyofestimatesCountry‐level estimates of mortality for 2004 and 2008 previously released on the WHO website included guidance to users on the data sources and methods used for each country, in terms of four levels of evidence. Comprehensive uncertainty ranges have not yet been addressed for the GHE cause of death estimates although uncertainty ranges are available for many of the component analyses for specific causes (refer to the detailed documentation of sources in Sections 4 and 5). General guidance on the quality and uncertainty of these cause of death estimates for years 2000‐2011 is provided in terms of the quality of data inputs and methods used. These are broadly summarized for WHO Member States in Annex Table F for general mortality and cause‐of‐death methods.
WHO’s adoption of health estimates is affected by a number of factors, including a country consultation process for country‐level health estimates, existing multi‐agency and expert group collaborative mechanisms, and compliance with minimum standards around data transparency, data and methods sharing. More detailed information on quality of data sources and methods, as well as estimated uncertainty intervals, is provided in referenced sources for specific causes (Sections 4 and 5).
Calculated uncertainty ranges depend on the assumptions and methods used. In practice, estimating uncertainty in a consistent way across health indicators has had limited success (i.e., estimates with uncertainty typically reflect some, but not all, source of uncertainty). Most methods for estimation of uncertainty rely on statistical techniques to assess variations across observations and take into account sampling error but are less successful in dealing with unknown systematic bias in observations. In particular, there is not yet sufficient research or consensus on the interpretation and use of verbal autopsy studies to ensure that systematic bias in assigning underlying cause of death can be fully addressed or resulting uncertainty fully quantified.
The type and complexity of models used for global health estimates varies widely by research/institutional group and health estimate. More complex models are necessary to generate more accurate uncertainty intervals. As expected, these are more difficult to transfer across research groups and require greater researcher expertise and time and computational resources to run.Where data are available and of high quality, estimates from different institutions are generally in agreement. Discrepancies are more likely to arise for countries where data are poor and for conditions where data are sparse and potentially biased. This is best addressed through improving the primary data.
Country health information systems, including vital registration, need to be strengthened as a matter of priority, in order to provide a more solid empirical basis for monitoring health situation and trends is essential. Such data are also crucial for Member States’ monitoring of local trends in order to respond to the changing needs of their populations.
To improve monitoring of mortality, morbidity and risk factors the improving health information systems should focus on strengthening:
Death registration through civil registration and vital statistics systems (CRVS), local health and demographic studies and other sources
Cause of death data collection through vital registration and verbal autopsy in communities
Regular household health surveys that include biological and clinical data collection
Complete facility recording and reporting with regular quality control
Although the GHE estimates for years 2000‐2011 have large uncertainty ranges for some causes and some regions, they provide useful information on broad relativities of disease burden, on the relative
WorldHealthOrganization Page34
importance of different causes of death, and on regional patterns and inequalities. The data gaps and limitations in high‐mortality regions reinforces the need for caution when interpreting global comparative cause of death assessments and the need for increased investment in population health measurement systems. The use of verbal autopsy methods in sample registration systems, demographic surveillance systems and household surveys provides some information on causes of death in populations without well‐functioning death registration systems, but there remain considerable challenges in the validation and interpretation of such data.

These estimates for years 2000‐2011 supercede and replace all previous estimates for global and regional causes of death published by WHO. They are not directly comparable with previous WHO estimates for 2008 and earlier years and differences should not be interpreted as trends. Figures 7.2 and 7.3 provide summary comparisons of the GHE estimates for year 2008 with the previous WHO estimates for year 2008 published in 2011 (4,5). These figures illustrate that there has been little change in the relative ranking for the leading causes of death, although estimated numbers of deaths are somewhat lower for most causes. This partially reflects downwards revision of all‐cause envelopes in recent successive revisions by UN‐IGME and UN Population Division, but also reflects accelerating declines in child mortality, and to a lesser extent, adult mortality in recent years.
These are provisional estimates and will be further revised in the process of updating to 2012 for release at country level in late 2013. WHO and collaborators will continue to include new data and improve methods, and it is anticipated that some causes will be further updated in the next revision.

a Deaths coded to “Symptoms, signs and ill-defined conditions” (R00-R99) are distributed proportionately to all causes within Group I and Group II.
b For deaths under age 5, refer to classification in Annex Tables B and C.
c As from 2006, deaths from causes F10-F19 with fourth character .0 (Acute intoxication) are coded to the category of accidental poisoning according to the updated ICD-10 instructions.
d Cancer deaths coded to ICD categories for malignant neoplasms of other and unspecified sites including those whose point of origin cannot be determined, and secondary and unspecified neoplasms (ICD-10 C76, C80, C97) were redistributed pro-rata across the footnoted malignant neoplasm categories within each age–sex group, so that the category “Other malignant neoplasms” includes only malignant neoplasms of other specified sites (Ref Mathers et al 2006 DCP chapter).
e Ischaemic heart disease deaths may be miscoded to a number of so-called cardiovascular “garbage” codes. These include heart failure, ventricular dysrhythmias, generalized atherosclerosis and ill-defined descriptions and complications of heart disease. Proportions of deaths coded to these causes were redistributed to ischaemic heart disease as described in (GPE discussion paper). Relevant ICD-10 codes are I47.2, I49.0, I46, I50, I51.4, I51.5, I51.6, I51.9 and I70.9.
f Injury deaths where the intent is not determined (Y10-Y34, Y872) are distributed proportionately to all causes below the group level for injuries.
g For countries with 3-digit ICD10 data, for “Road injury” use: V01-V04, V06, V09-V80, V87, V89 and V99. For countries with 4-digit ICD10 data, for “Road injury” use:
