School vending machine use and fast-food restaurant use are associated with sugar-sweetened beverage intake in youth.

"To examine associations between use of school vending machines and fast-food restaurants and youth intake of sugar-sweetened beverages... From a group randomized obesity intervention, we analyzed baseline data from 1,474 students in 10 Massachusetts middle schools with vending machines that sold soda and/or other sweetened drinks... Among 646 students who reported using school vending machines, 456 (71%) reported purchasing sugar-sweetened beverages. Overall, 977 students (66%) reported eating at a fast-food restaurant... Among students who use school vending machines, more report buying sugar-sweetened beverages than any other product category examined. Both school vending machine and fast-food restaurant use are associated with overall sugar-sweetened beverage intake."
