ReviewHealth Impact Assessment of Transportation Projects and Policies: Living Up to Aims of Advancing Population Health and Health Equity?
Health impact assessment (HIA) is a forward-looking, evidence-based tool used to inform stakeholders and policy makers about the potential health effects of proposed projects and policies and to identify options for maximizing potential health benefits and minimizing potential harm. This review examines how health equity, a core principle of health impact assessment (HIA), has been operationalized in HIAs conducted in the United States in one sector, transportation. Two perspectives on promoting health equity appear in the broader public health research literature; one aims at reducing disparities in health determinants and outcomes in affected populations, whereas the other focuses on facilitating community participation and self-determination. ⋯ Fewer than half of the HIAs assessed current health disparities or changes in their distribution. Only 15% of HIAs addressed equity by focusing on capabilities development or empowerment. Routinely assessing and reporting how an HIA aims to address health equity might better manage expectations and could make HIA practitioners and users more conscious of how an HIA can realistically be used to advance health equity.

In recent decades, there has been remarkable growth in scientific research examining the multiple ways in which racism can adversely affect health. This interest has been driven in part by the striking persistence of racial/ethnic inequities in health and the empirical evidence that indicates that socioeconomic factors alone do not account for racial/ethnic inequities in health. ⋯ For each mechanism, we describe key findings and identify priorities for future research. We also discuss evidence for interventions to reduce racism and describe research needed to advance knowledge in this area.
