A new special supplement in the Journal of Public Health Management and Practice released this week introduces the broad public health practice community to the field of legal epidemiology and its principles. The supplement, Advancing Legal Epidemiology, demonstrates the field’s application to study and evaluate chronic and non-communicable disease-related policies. The open access issue features 13 original articles, including nine research studies, that illustrate a compelling and diverse body of research that exemplifies how legal epidemiology can help public health practitioners and policymakers recognize opportunities for achieving better health outcomes through law and policy. It is co-sponsored by the Center for Public Health Law Research and the CDC’s Division of Heart Disease and Stroke Prevention.
