About Social Determinants of Health (SDOH)

What are social determinants of health?

Social determinants of health (SDOH)external icon are conditions in the places where people live, learn, work, and play that affect a wide range of health risks and outcomes.

Healthy People 2030 uses a place-based framework that outlines five key areas of SDOH:

The World Health Organizationexternal icon also provides a definition of social determinants of health. Social determinants of health as the conditions in which people are born, grow, live, work and age. These circumstances are shaped by the distribution of money, power, and resources at global, national, and local levels. They state social determinants of health are mostly responsible for health inequities – the unfair and avoidable differences in health status seen within and between countries.

How can addressing social determinants of health improve health?

Resources that enhance quality of life can have a significant influence on population health outcomes. Examples of these resources include safe and affordable housing, access to education, public safety, availability of healthy foods, local emergency/health services, and environments free of life-threatening toxins. Healthy People 2030 highlights the importance of addressing SDOH by including “social and physical environments that promote good health for all” as one of the four overarching goals for the decade.

We also know that poverty limits access to healthy foods and safe neighborhoods and that more education is a predictor of better health. Differences in health are striking in communities with poor SDOH such as unstable housing, low income, unsafe neighborhoods, or substandard education. By applying what we know about SDOH, we can not only improve individual and population health but also advance health equity.
