Is volunteering associated with metabolic syndrome or diabetes among Black adolescents from lower-income households?In this cohort study including 1379 Black adolescents from 2 separate studies, those who volunteered, and who volunteered more frequently, had fewer indications of metabolic syndrome; higher purpose in life statistically mediated this association. Also, Black adolescents who volunteered had reduced odds of diabetes in adulthood.These findings suggest that activities intended to benefit others may relate to better cardiometabolic health among volunteers themselves, suggesting that volunteering could be one positive component of the social determinants of health.
