Overview of the process of health impact assessment with specific focus on quantitative effect analysis. The left side of the figure shows a generalised Health Impact Assessment process, while the right side focuses on the effect analysis stage, involving two subanalyses: (1) the potential effects of the policy on population (or subpopulation) exposure to selected determinants of health (changed exposure) were estimated based on an analysis of the policy, study population characteristic and information on baseline level of exposure to determinants of health. (2) Next, the potential effect of changed population exposure to determinants of health on burden of disease was estimated based on the results of the first subanalysis (change in exposure to health determinants), information on baseline level of burden of disease from the included health outcomes and causal effect estimates of the associations between included determinants of health and health outcomes. The change in burden of disease was estimated for both each determinant of health and each health outcome and aggregated for all included health outcomes (model was developed based on⁷).
