以学校为平台的儿童肥胖防控效果评价

目的:探索儿童肥胖的有效干预模式,遏制我国儿童肥胖率的快速增长。方法:采用分层整群随机抽样方法。在济南市抽取大中小三种规模的小学各两所,其中一所作为干预校实施干预,另一个作为对照校。每所学校2～5年级随机抽取两个班的小学生作为研究对象。基线和终期时对所有研究对象进行肥胖相关知信行问卷调查和体格检查。收集到的数据用Epi Data3.0录入和SPSS16.0进行统计分析。结果:小学生超重和肥胖流行严重(超重率19.54%,肥胖率18.70%),终期时干预组情况好于对照组,干预起到一定效果。干预能够显著提高小学肥胖相关知识、态度、行为得分,但对血脂和血糖的干预效果不佳。结论:有些指标干预前后并没有出现统计学差异,可能与干预时间短有关,但有些指标已显示出上升或下降的趋势,因此以学校为平台的干预方式值得继续推广。

Evaluating the effect of school-based children obesity prevention and control

Objective To explore the effective intervention mode to control children obesity.Methods Six primary schools were chosen from Jinan with stratified cluster random sampling,in which every two schools were chosen from schools with the same scale.In each school,two classes were randomly chosen from grade two to five and surveyed with questionnaire of obesity-related KAP and physical examination.And the data was input with software of Epi Data 3.0 and analyzed with statistic software of SPSS11.0.Results There had high prevalence rate of overweight and obesity in primary school students.After being intervened,the scores of obesity-related knowledge,attitudes,behavior of primary school students had significantly improved.But there didn’t have significant differences of blood lipids and blood glucose between experimental group and control.Conclusion Some indexes had not significant difference before and after intervention,which may be related to short time of intervention.But some other indexes were different before and after intervention,which means that the mode of school-based children obesity prevention and control should be continuously popularized.
