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

The purpose of a health impact assessment (HIA) is to evaluate the potential health effects of a project or policy. This process involves systematically considering how a proposed project or policy may affect the health of a population. HIAs help decision-makers understand the potential health implications of their choices, allowing for informed planning and implementation that can enhance health benefits or mitigate negative health impacts. By examining various factors, including environmental, social, and economic influences, HIAs serve as a crucial tool in promoting public health and ensuring that health considerations are integrated into broader decision-making processes.
