成都市中小学生超重 肥胖流行现状分析

Analysis of the prevalence status of overweight and obesity in students in Chengdu

目的了解成都市中小学生超重、肥胖的发生情况,为制定中小学生肥胖防治措施提供依据。方法四川大学华西第二医院儿童保健科2006年在成都市5城区中小学中整群抽样,测量身高、体重,计算体重指数(BMI),使用"中国学龄儿童超重、肥胖BMI筛查分类"参考标准进行超重、肥胖判断,计算超重、肥胖检出率。结果超重检出率男14.1%、女8.2%,肥胖检出率男6.8%、女3.2%;男性超重和肥胖检出率都比女性高,经χ2检验,差异有统计学意义(超重χ2=281.05、肥胖χ2=73.29,P均<0.01)。无论男女,7～<12岁组和12～<19岁组之间超重检出率比较,差异无统计学意义(男χ2=1.429,女χ2=0.862,P均>0.05)。男女肥胖检出率比较,差异有统计学意义,7～<12岁组肥胖检出率高于12～<19岁组(男χ2=11.70,女χ2=10.14,P均<0.01)。结论成都市中小学生超重、肥胖检出率高,有必要制定相应防治措施防止肥胖大规模流行;有必要制定成都市中小学生BMI参考值。

Objective To analyze the prevalence status of overweight and obesity in students, so as to take effective preventive measures against obesity. Methods Students of random cluster sampled from middle and elementary schools in Chengdu were measured weight and height and then BMIs （body mass index） were caculated. Students with overweight or obesity were screened by the ＂Reference Norm for Screening Overweitht and Obesity in Chinese Children and Adolescents＂ , which is set up by the Working Group on Obesity in China. Results The overweight detection rates in boys and girls were 14.2% and 8.2% respectively, and obesity rotes were 6.8% and 3.2% respectively. Differences existed between boys and girls both in overweight and in obesity. There were no differences about overweight detection rates between group 7- 12 year and group 13 - 18 year both in boys and girls, but differences about obesity existed between these two groups. Conclusion The detection rates of overweight and obesity in students in Chengdu are so high that there may exist some prevalence potentiality. It＇s necessary to apply some corresponding measures to obesity prevention and treatment. It＇ s necessary to set up a reference value for students in Chengdu.
