In this brief, we report the association between eighth-grade students' purchases of sugar-sweetened beverages and snack foods and 2 policy targets: (1) exposure to food marketing through screen-based media and (2) availability of sugar-sweetened beverages and snack foods in schools. Data were obtained from the Early Childhood Longitudinal Study eighth-grade panel (n = 8945). Multinomial logistic regressions were used to estimate associations among hours spent using screen-based media, availability of beverage and snacks for purchase, and adolescent sugar-sweetened beverage and snack purchases at school. Exposure to media and school availability were significantly associated with higher risk of daily and occasional purchases of in-school beverages and snacks. Limiting the availability of sweetened beverages without limiting marketing may not lead to effective policy.
