What is the purpose of a health impact assessment (HIA)?

The purpose of a health impact assessment (HIA) is to evaluate the effects of policies on population health. HIAs are systematic processes that help determine how proposed decisions or projects may affect the health of individuals and communities. By analyzing potential health implications, HIAs aim to provide policymakers with insights that can lead to healthier decisions and outcomes. This evaluation considers both positive and negative health impacts and involves engaging stakeholders to ensure that the perspectives of affected communities are included. As a result, HIAs can influence policy development by highlighting health considerations that might otherwise be overlooked.

The other options do not accurately capture the comprehensive purpose of an HIA. While promoting health projects and reducing healthcare spending are related to health, they aren't the primary focus of an HIA, which is much more centered on analyzing policy impacts. Similarly, while technology can be assessed in certain contexts, an HIA encompasses a broader scope beyond just technological assessments, considering a wide range of social, economic, and environmental factors that influence health outcomes.
