Survey on the prevalence of obesity in primary, junior and senior high school students at Minhang distrct

[目的 ] 了解上海市闵行区中小学生肥胖和超重患病率情况 ,为预防儿童肥胖制订防制策略及措施提供基础资料。 [方法 ] 普查区内共 40 3 10名中小学学生的身高体重。采用体重指数 (BMI)和身高别体重法同时评价调查对象的肥胖患病率。 [结果 ] 研究人群平均年龄 ( 12 .5 9± 3 .0 7)岁 ,总体BMI为 18.63± 3 .3 1,其中男性BMI高于女性。以BMI法为评价标准总体肥胖患病率为 2 .76%,超重患病率为 11.5 7%;以身高别体重法为参考标准则肥胖的患病率为 6.17%,超重的患病率为 6.76%,两种评价方法的总体患病率差异有极显著性。肥胖和超重患病率总体上呈现男高女低 ,并随年龄增加而逐渐减低。 [结论 ] 闵行区中小学生的肥胖总体患病率呈现随年龄的增高而逐渐降低趋势。中小学生超重比例较高 ,应及早制订防制策略及措施 。

Objective] To investigate the prevalence of obesity in students at Minhang, thus give basic data to develop strategy and measures for the control of obesity among children. [Methods] 40310 students in all the primary schools, junior and senior high schools were investigated. Body weight and height were measured. Body weights were evaluated both by body mass index (BMI) and height to weight standards. [Results] The mean age of the subjects was 12.59±3.07 years old and the mean BMI was 18.63±3.31. The mean BMI was significantly higher in male students than female students. The prevalence of obesity was 2.76% and overweigh was 11.57% using BMI standard, while the prevalence of obesity was 6.17% and overweight was 6.76% using height to weight standard. There existed significant statistical difference on the prevalence of obesity and overweight between the two standards. The prevalence of obesity and overweight was significantly higher in male than female. The prevalence of both obesity and overweight decreased with the increasing of age. [Conclusion] The overall prevalence of obesity in the present study was decreasing with age while the prevalence of overweight of the student was increasing. It is important to develop strategy and measures to reduce the prevalence of obese children as soon as possible.
