Introduction to the "Evaluating the Impact of Structural Policies on Health Inequalities and Their Social Determinants and Fostering Change" (SOPHIE) Project.

The SOPHIE Project (acronym for Structural Policies for Health Inequalities Evaluation) has focused on evaluating the impact of structural policies on health equity, considering as such all those policies that exert a powerful influence on the structural determinants of health (e.g., patterns of social stratification, living and working conditions) and thus on health-related exposures through intermediary determinants. In these sections of the International Journal of Health Services, we present some of the main findings of the SOPHIE Project. We include both articles that summarize all the evidence already published in the project on a thematic area (such as labor market, gender, or housing) and articles that present new, unpublished evidence on a specific health inequality or policy.
