背景：以学校为基础的肥胖预防干预措施的不一致效果可能与不同的亚组接受干预的方式有关。本研究的目的是评估干预计划的效果，包括向家长和课堂组件提供情况说明书，对含糖饮料（SSB）的摄入量和屏幕时间的影响。此外，探讨是否潜在的影响和父母的参与不同的青少年的性别，体重状况（WS）和父母的教育level.Methods：总共，1465 11岁的孩子参加了在预测试和8个月的中途评估的HEIA研究。父母（n = 349）提供了过程评价数据。从11岁的儿童中收集SSB的自我报告摄入量，评估频率和数量，而观看电视/DVD和电脑/游戏使用的时间（工作日和周末）则通过频率测量进行评估。从父母那里收集了关于干预措施和接受剂量的认识数据。协方差分析（ANCOVA）进行测试的影响，性别和适度的WS和父母的教育。结果：时间花在电视/DVD（周p = 0.001，周末p = 0.03）和电脑/游戏的使用（周p = 0.004，周末p = 0.003），
Background: Inconsistent effects of school-based obesity prevention interventions may be related to how different subgroups receive them. The aim of this study was to evaluate the effect of an intervention program, including fact sheets to parents and classroom components, on intake of sugar-sweetened beverages (SSB) and screen time. Further, to explore whether potential effects and parental involvement varied by adolescents' gender, weight status (WS) and parental educational level.Methods: In total, 1465 11-year-olds participated at the pre-test and the 8 month mid-way assessment of the HEIA study. Parents (n = 349) contributed with process evaluation data. Self-reported intake of SSB was collected from the 11-year-olds assessing frequency and amount, while time used on watching TV/DVD and computer/game-use (weekday and weekend day) were assed by frequency measures. Data on awareness of the intervention and dose received were collected from parents. Covariance analyses (ANCOVA) were conducted testing for effects by gender and for moderation by WS and parental education.Results: Time spent on TV/DVD (week p = 0.001, weekend p = 0.03) and computer/game-use (week p = 0.004, weekend p
