This profile offers an overview of the social, economic, and environmental factors that shape the health of the American Indian and Alaska Native (AI/AN) population in the United States. Considering the unique environments, cultures, histories, and circumstances of AI/AN populations is fundamental to improving their health outcomes and reducing longstanding disparities and inequities. These factors, known as social determinants of health (SDOH), affect various health, functioning, and quality-of-life outcomes and risks. Non-medical factors like poverty, limited access to healthcare, and lack of education are all examples of individual SDOH that contribute to health disparities and inequities.
