Social epidemiology
Social epidemiology is defined as "The branch of epidemiology that studies the social distribution and social determinants of health," that is, "both specific features of, and pathways by which, societal conditions affect health."
Social epidemiology overlaps with fields in the social sciences, most notably medical anthropology, medical sociology, and medical geography. However, these latter fields often use health and disease in order to explain specifically social phenomenon (such as the growth of lay health advocacy movements), while social epidemiologists generally use social concepts in order to explain patterns of health in the population.
