چکیده
Although educational attainment and physical activity levels tend to be positively associated in majority populations, this relationship has not been investigated in American Indian and Alaska Native (AI/AN) elders. This study examined the association between education and physical activity among AI/AN elders (N = 107) using self-report and behavioral outcomes. Regression models showed that higher education was signifi cantly associated with total caloric expenditure for moderateintensity physical activities and distance traveled during a 6-minute walk test of fi tness. Additional research is needed to understand modifi able personal, social, and environmental physical activity barriers in these populations.
