Social determinants of health—the circumstances in which people are born, grow, live, work, and age that affects health and quality of life—are strongly connected with disparities in health status and life expectancy. Research has found that individual behavior, often driven by social determinants, accounts for up to 40 percent of the risk of premature death. These findings helped establish the Commission on Social Determinants of Health by the World Health Organization (WHO) in 2005. The Commission's responsibilities require that they assemble, collate, and synthesize global data on SDOH and its impact on health inequity, and to make recommendations for action to address that inequity. The goal of the Commission is simple: to foster a global movement on SDOH and health equity.
