摘要:
评估以学校为基础的肥胖综合干预方法的效果,为探索适合小学生肥胖的干预模式提供依据.方法 采用多阶段随机整群抽样方法,在南京城区选择8所小学四年级全部在校学生作为研究对象.采用以学校为单位完全随机分组,干预组和对照组各4所小学,干预组于2010年5月-2011年4月实施为期1年的肥胖现场综合干预.对照组除常规健康教育和体育课外,不采取任何干预措施.基线调查1 182人(干预组638人,对照组544人),干预后随访共1 129人(干预组616,对照组513人).结果 1年后,干预组身高、腰围均高于对照组,差异均有统计学意义.干预前对照组和干预组超重和肥胖率分别为26.5%,27.4%,干预后对照组和干预组超重和肥胖率分别为20.9%,21.1%,差异均无统计学意义(P值均>0.05).实施干预活动1年后,干预组学生肥胖相关的健康知识知晓率有明显改善,与对照组相比,除“多吃蔬菜和水果对健康有好处”外,其余差异均有统计学意义(P值均<0.05).结论 干预工作对改善儿童青少年肥胖控制相关知识的知晓产生一定效果,但肥胖控制效果不理想.

Abstract:
Objective To evaluate the impact of a school-based intervention for obesity in elementary students in order to provide evidence for exploration of the effective pattern of childhood obesity intervention.Methods A cluster randomized controlled trial was used to select 8 randomly in urban primary schools.Each school was randomly assigned to either the intervention or control group (four schools in each group).Participants were the 4th grade in each participating school.The field intervention was planned to be implemented among intervention group from May 2010 to April 2011.Baseline survey was conducted among 1 182 people(638 people in intervention group,544 people in control group),and 1 129 people were interviewed after intervention(616 people in intervention group,513 people in control group).Results The prevalence of overweight and obesity was 26.5%,27.4% in control group and intervention group before implementation of intervention activity,respectively.The prevalence of overweight and obesity was 20.9%,21.1% in control group and intervention group after implementation of intervention activity,respectively.The differences were of no statistical significance(P>0.05).After one year intervention,students' knowledge,except for the knowledge about "it is good to eat more vegetable and fruits",increased significantly in the intervention group,compared to control group (P<0.05).Conclusion School-based intervention for obesity is successful to improve students' knowledge change relating to obesity control,however it is not effective to control obesity.
