Health Impact Assessments: What, Why, How, Who, Where?
December 3, 2010
Michele J. Orza, ScD
Increasingly, a wide range of people from economists to epidemiologists are taking a broad-based, comprehensive approach to improving the public’s health and working on many fronts simultaneously. An important means for implementing this approach, often characterized as "health in all policies," is the health impact assessment (HIA). These assessments are intended to bring a health focus to policies, programs, and projects in other sectors, such as agriculture, energy, and transportation, where the effects of the proposed action on health might not be adequately considered—or considered at all. HIAs are a vehicle for supporting policymaking intended to advance the public's health by making explicit the health effects of the various alternatives under consideration.
This Forum session provided an introduction to health impact assessments, examined several examples and their effect on policy and health outcomes, and discussed future opportunities and challenges for this burgeoning health policy practice.
