Ethiopia

• Repeated national surveys, give trends to region or zone level (WMS, DHS)• EOS screening data (AC, then w/h)• Area level surveys, often following EOS data signals• Several others, e.g. SCF sentinel repeated surveys (discontinued)• Sentinel use of screening data (first stage) might be feasible

Advantages DisadvantagesQuantity of data more manageable Gaps in the system (missed areas of

deterioration)Quality of data improves Possible ‘Hawthorne’ effectTrend analysis more manageable Trigger for action set to prevalence levels

not trends (system provides trends not prevalence levels)

Data collection cycle can be shortened Does not address the needs of non-sedentary populations

Capacity building improves with focused resources

Capacity for analysis at sites may not by sustainable

Sentinel approach

means selecting limited number of sites for focusing data collection/analysis, usually chosen as most likely to show change – these can be clinics or programme sites capturing data already collected, or clusters for sampling for new surveys

Sources: WHO, Global Database on Child Growth and Malnutrition; CSA, 1996; CSA, 1998; CSA, 2000; DHS, 2000; CSA, 2004* Levels of accuracy in the Table 1 refer to levels published in survey’s reports. These surveys exclude non-sedentary populations (did not sample some zones in Afar and Somali regions), and are therefore accurate only to the sedentary populations of geographic areas. The 2004 WMS (data from 2005) excludes Gambella region entirely. Gambella region has had high levels of malnutrition in the past (i.e. the 2000 WMS reports 13% wasting, 32% underweight, and 40.5% stunting).

Somalia – FSAU

• Agro-met, satellite, animal and crop conditions, prices, etc• Area level surveys, including wasting in children: sentinel site and ad hoc surveys

Botswana• National surveys, BFHS (Family Health Surveys), MICS 2000• Clinic-based reporting (BNNSS)
