The June issue of Health Affairs explores the pursuit of health equity, and the relationship between health equity and social factors. Studies compare health and health disparities in 32 countries; show U.S. progress in reducing racial disparities in surgical mortality and kidney transplantation rates; and how housing assistance can improve access to health care, among other topics. “Early evidence of health disparities led to a focus on the health care system – the roles of bias and discrimination, as captured by the title of the 2003 [Institute of Medicine] report ‘Unequal Treatment,’” notes editor-in-chief Alan Weil. “Yet…growing understanding of the role of social factors in determining health outcomes makes it clear that achieving equity requires widening the lens.”
