兰州市小学生超重肥胖与锻炼及学校周边环境关联性分析
|
摘要
目的了解兰州市小学生超重肥胖现象与锻炼及学校周边环境因素的相关性,为降低学生超重肥胖率提供参考。方法采用分层整群随机抽样方法,选取兰州市4个区8所小学四到六年级共3 600名学生进行身高、体重测量。运用Logistic回归模型,分析学生超重肥胖与锻炼及学校周边环境因素的关联。结果兰州市小学生超重率为13.8%(男生18.0%,女生9.5%),肥胖率为10.8%(男生11.7%,女生9.8%);性别间超重率差异有统计学意义(χ~2=55.10,P<0.01),肥胖率差异无统计学意义(χ~2=3.39,P=0.07)。Logistic回归分析结果显示,引起男生超重、肥胖的学校周边环境影响因素主要有网吧数量(OR=1.81),女生主要为周边快餐店数量(OR=2.39)。结论学校周边网吧、快餐店数量多是引发学生超重肥胖的重要因素。建议有关部门加强学校周边环境建设,以降低小学生超重肥胖现象的发生。
Objective To analyze correlation between overweight and obesity among primary school students in Lanzhou with exercise and environmental factors around schools, and to provide a reference for reducing the overweigh and obesity rate of students. Methods Using cluster random sampling method, a total of 3 600 pupils from grade 4 to grade 6 in 8 primary schools in 4 districts of Lanzhou were investigated. Logistic regression model was used to analyze the relationship between overweight and obesity, exercise and environmental factors surrounding schools. Results The overweight rate was 13.8%(18.0% for boys and 9.5% for girls) and the obesity rate was 10.8%(11.7% for boys and 9.8% for girls), there was statistical significance in the differences of overweight rate between genders(χ~2=55.10, P<0.01). There was no statistical significance in the differences of obesity rate between genders(χ~2=3.39, P=0.07). The primary environmental factors causing overweight and obesity among boys included number of Internet cafes(OR=1.81), while for girls it was number of fast food restaurants(OR=2.39). Conclusion Too many Internet cafes and fast food restaurants surrounding school associates with higher risk of obesity among students. Public health interventions should be implemented targeting surrounding environment of schools, which might help reducing the occurrence of overweight and obesity in primary school students.
