“Health in all Policies…”
"(The) toxic combination of bad policies, economics, and politics is, in large measure, responsible for the fact that a majority of people in the world do not enjoy the good health that is biologically possible.” WHO Commission on Social Determinants of Health, 2009
Health in all policies. APHA supports requiring all new federal policies and programs to take into consideration all Impacts, both positive and negative, on the public’s health.
Health in all policies, but… No common language:
transportation engineers don’t understand health data. public health professionals don’t understand the constraints
and limitations of the planning process Few routine/formalized requirements No standard forums where health works with other
sectors No funding for new public health activities “Going out on a limb:”
Public health is science-driven, and policy and planning are governed by many other considerations: economics, politics, technology, deadines, etc …

DefinitionsIAIA
A combination of procedures, methods and tools that systematically judges the potential effects of a policy, programme or project on the health of a population and the distribution of those effects within the population. HIA identifies appropriate actions to manage those effects.(IAIA, 2006)
Analytical Framework
Proposed policy, project, program
Determinants of health
Health outcomes
• Broad framework: considers multiple determinants and dimensions of health
• Considers direct, indirect, and cumulative pathways• Both qualitative and quantitative methods used, as is
expert opinion• Focus: predicting outcomes or pathways/linkages, in order
to manage effects
The HIA Process
1.Screening –is HIA feasible and likely to add value? 2.Scoping – determine the important health effects,
affected populations, available evidence, etc3.Assessment – analyze baseline conditions and likely
health effects4.Recommendations – develop health-based recs and a
feasible plan for implementing them5.Reporting – disseminate the report to the public,
stakeholders, solicit input6.Monitoring and Evaluation

Examples of Housing HIAsJack London Gateway (JLG) Senior Housing Project
Authors: Human Impact Partners and SFDPH
Decision: Plan for 61 new senior housing units close to 2 freeways & Port of Oakland. Impacts: indoor & outdoor air quality, noise, safety, retail planningRecommendations: AQ monitoring; installation of ventilation systems; noise-insulating windows; pedestrian protection medians; traffic calming measures; and many others.

Outcomes:• Many recommendations
adopted.• Additional HIA projects
were funded. • Healthy Development
checklist adopted by the Development Committee.
Integrating HIA into the environmental impact statement process:
Decision: Bush energy plan proposed expanded oil leasing in Alaska’s North Slope, necessitating an EIS
• Local government became a “cooperating agency” – a role through which local governments can formally participate in an EIS
• The community health agency drafted an HIA through this role
• The lead federal agency incorporated the HIA into the EIS
Oil and gas leasing on Alaska’s Arctic Slope
A small Inupiat community 7 miles from large oil development
Community testimony:Benefits: revenues pay for services, infrastructureRisks: social change, drugs and alcohol, STIs, contaminants, cancer, and breathing problems, interference with hunting and fishing
Result of the NPR-A HIA?
Health Concern Mitigation
Dietary change from interference with hunting and fishing (exacerbating risk of diabetes, obesity, etc)
BLM withheld critical hunting areas from leasing in part because of health and broader cultural impacts
“Social ills”: alcohol, STIs,
Expand cultural orientation for workers
Air pollution Additional baseline, modeling, and monitoring above CAA requirements.
Contamination of local food sources
Baseline levels and ongoing monitoring
Examples of HIAsPaid Sick Days
Workers’ rights issue vs. Public health issueDisparities: income, race/ethnicity, occupation
Methods: Lit and health data review, statistical analyses, focus groups
Key Findings: ER visits, flu spread restaurant workers, nursing homes
Outcomes: Changed discourse, revitalized campaigns across US
What are the elements that define HIA?
1. Forward-looking: addresses a proposed action2. Seeks to inform decision-making3. Follows 6 steps (5 in some texts)4. Broad framework: broad def’n of health; considers social,
economic and environmental influences on health5. Participatory process: engages the public and other
stakeholders6. Cross-disciplinary: effective collaboration with decision-
makers, other agencies 7. Focus on vulnerable populations/equity
The Health Impact Project:A collaboration of the Robert Wood Johnson Foundation and The Pew Charitable Trusts
Overall Objective: To promote and support the use of HIA as a tool to ensure that decisions in non-health sectors, whether at the local, state, tribal, or federal level, are made with health in mind.

The Health Impact Project Funded Projects
1.State Budget Process: New Hampshire Center for Public Policy will address the NH budget
2.State Cap-and-Trade regulations: CA DPH an HIA to inform the rulemaking process for California’s carbon cap and trade rule
3. Agriculture Policy: Kohala Center, a nonprofit in HI, will do an HIA to inform HI County’s A non-profit would engage in a county agricultural plan that will shape the local economy, land use patterns, and diet.
4.Wilshire Transportation Corridor, LA: LA DPH and UCLA will do an HIA of planned transportation corridor in LA
5.Farm to School Legislation: a non-profit in OR will do an HIA to inform deliberations on a farm to school bill.

The Health Impact Project CFPFunded Projects
7. Transit Oriented Development: a. ISAIAH (a faith-based coalition) will use HIA to address planning
decisions on a light-rail project in the Twin Cities.b. TSU will use HIA to look at a proposal for TOD
8. Coal Gasification Plants: Green River Health Department will do an HIA of 3 proposed “clean coal” plants in KY
9. Construction waste power plant: Mass. Dept of Public Health will do an HIA of a proposed biomass power plant in an economically depressed area of Springfield, MA
10.Farm to School legislation: an OR non-profit public health group will undertake and HIA of proposed legislation to fund farm to school programs
HIA and Science
HIA practitioners may be experienced and well-versed in public health, but it is a misguided conceit to predict the nature and extent of a health impact without substantiating this by reference to empirical data (…most of which is uncertain and won’t substantiate impacts)Thompson
…it is not reasonable to suggest that uncertainty should
prevent HIA from making any predictions. Certainty or even
high probability are luxuries which HIA practitioners do not
enjoy…it is little help to the decision-maker to be told that
they should wait 5 years for more research
Kemm
Questions for discussion
1. Are there minimum standards of evidence that could be applied without restricting the range of potential applications of HIA? What are they?
2. How should HIA handle predictions in which there are potentially important health effects and a high degree of uncertainty regarding the predictions?
3. How can HIA avoid becoming a biased tool for advocacy when it relies on subjective judgments

Northeast NPR-A Example: hunting and diabetes
Baseline:• Type 2 diabetes prevalence low: ~2.5%• Diet: ~50% “wild foods” – caribou, salmon, marine
mammalsImpact Assessment:
Pipelines
Revenue
“Seismic”
Displace caribou farther from village
Fuel & equipment for hunting
Dietary Change
Diabetes Risk

AssessmentYour data are incomplete, your predictions are uncertain…
What to do?? … Adaptive Management
