摘　　要：目的探讨基于学校环境的学生超重肥胖综合干预效果,为预防和控制中小学生超重肥胖提供依据。方法采用多阶段分层整群抽样方法抽取重庆市主城区12所中小学9 933名学生,随机分为6所干预校和6所对照校,对干预校采取学校环境政策干预、健康教育、体育活动指导结合的综合干预,干预前后进行体格检查和问卷调查。结果干预后干预校超重率在原有基础上(12.9%)上升了0.2%,肥胖率(7.4%)未变化;对照校超重率、肥胖率分别在原有基础上(11.5%、7.7%)上升了0.5%、0.1%。干预前两组学校正常体重的学生在干预后BMI、腰围、臀围均升高(P<0.05),干预校超重肥胖的学生在干预后BMI、腰围均下降(P<0.05),对照校超重肥胖的学生在干预后臀围升高、腰围降低(P<0.05);干预校学生在干预后肥胖相关饮食问题正确率上升,不健康饮食行为报告率下降(P<0.05)。结论基于学校环境的学生超重肥胖综合干预能控制肥胖相关指标的增长速度,改善中小学生的饮食行为。Objective To evaluate consequence of a school-based overweight and obesity intervention, and to provide evidence to prevent and control obesity in primary and middle school students.
