Children’s Consumption of Fruits and Vegetables: Do School Environment and Policies Affect Choice At School and Away from School?
研究学校环境与政策对儿童水果蔬菜摄入量的影响，发现参与学校午餐计划的学生总摄入更多，且学校政策能同时改善在校和校外的饮食。
School environment and policies affect children’s healthy eating choices both at and away from school. We estimate their effect on fruit and vegetable intakes and control for the endogenous decision to participate in the National School Lunch Program. School meal participants consume more total fruits and vegetables, with relatively more at school and less away from school compared to nonparticipants. The policies had little effect on participation itself. Policies to restrict high fat milks or desserts for school lunch and selling competitive foods are associated with greater fruit and/or vegetable intake at school; some policies affected consumption of fruits and/or vegetables at home as well. Policies that encourage fruit and vegetable consumption can improve diets both at and away from school.
