健康青年场所（HYP）干预旨在通过培养成人和青年的环境改变技能和效能，增加水果和蔬菜消费（FV）和身体活动（PA）。HYP包括对成人学校现场负责人的团体培训，环境变化技能课程，以及由青年领导的FV和PA环境变化团队。16所学校被随机分为是否实施HYP项目。在六年级（基线）、七年级（干预后第1年）和八年级（干预后第2年）结束时，对参与者（N = 1582）进行FV和PA以及假设的HYP程序中介（例如代理功效）的评估。干预后，与对照学校相比，高质量学校的FV没有变化，但PA有显著变化。代理效能对学校PA环境的影响在项目效应中起中介作用。培养成人和青少年领导学校环境变化的技能和效能可能是促进青少年PA的有效方法。
The Healthy Youth Places (HYP) intervention targeted increased fruit and vegetable consumption (FV) and physical activity (PA) through building the environmental change skills and efficacy of adults and youth. HYP included group training for adult school site leaders, environmental change skill curriculum, and youth-led FV and PA environment change teams. Sixteen schools were randomized to either implement the HYP program or not. Participants (N = 1,582) were assessed on FV and PA and hypothesized HYP program mediators (e.g., proxy efficacy) at the end of sixth grade (baseline), seventh grade (Postintervention Year 1), and eighth grade (Postintervention Year 2). After intervention, HYP schools did not change in FV but did significantly change in PA compared to control schools. Proxy efficacy to influence school PA environments mediated the program effects. Building the skills and efficacy of adults and youth to lead school environmental change may be an effective method to promote youth PA.
