Health mindsets as a predictor of physical activity and body mass index in American Indian college students.

American Indians are at increased risk for cardiovascular disease in adulthood, and levels of physical activity and body mass index associate with cardiovascular disease risk. Recent research indicates that one's mindset may play a role in determining health behaviors and outcomes. In a sample of 105 American Indian college students, greater growth health mindset associated with lower body mass index. Bootstrapping analyses revealed a significant indirect effect of health mindset on body mass index through levels of physical activity. These findings suggest that interventions aiming to promote growth health mindsets may be successful in reducing risk for cardiovascular disease in American Indian college students.
