Health Risk Assessment

Health Risk Assessment (HRA) is a systematic public health approach used to identify, analyze, and evaluate potential risks to human health arising from environmental, occupational, behavioral, or biological factors. It helps estimate the likelihood and severity of adverse health outcomes in individuals or populations exposed to specific hazards. Health risk assessment typically involves hazard identification, exposure assessment, dose–response evaluation, and risk characterization. In public health practice, HRA supports evidence-based decision-making by guiding risk prevention, control measures, and policy development. It is widely applied in areas such as environmental health, food safety, occupational health, and chronic disease prevention. Health risk assessments also help identify vulnerable populations and prioritize interventions to reduce health inequalities. By providing scientific insights into potential health threats, HRA enables proactive planning, strengthens public health preparedness, and promotes safer environments and healthier communities.
