Health Impact Assessment (HIA) is a systematic process used to evaluate the potential health effects of a proposed project, policy, or program. It aims to inform decision-makers about how their actions may impact the health of communities and individuals. HIA considers various factors, including environmental, social, and economic influences on health. The process typically involves several steps, such as screening, scoping, assessment, recommendations, and monitoring. By engaging stakeholders and using evidence-based research, HIA helps ensure that health considerations are integrated into planning and decision-making, ultimately promoting healthier outcomes for affected populations.
