徐州市儿童单纯性肥胖调查及不同诊断标准的比较分析

目的　调查徐州市小学生单纯性肥胖患病情况 ,比较标准体重法与新标准BMI法判断儿童肥胖的差异。方法　采用多阶段分层整群抽样方法 ,对徐州市 2 5所小学 1～ 5年级学生进行调查并体检。结果　标准体重法 ,徐州市 7～ 11岁儿童超重与肥胖的总检出率分别为 13.3%、17.4 % ,肥胖 -超重比 (OOR)为 0 .8;新标准BMI法 ,徐州市 7～ 11岁儿童超重与肥胖的总检出率分别为 12 .2 %、11.3% ,OOR为 1.1;新标准男、女儿童超重与肥胖的检出率均低于标准体重法 (P <0 .0 1) ,而OOR值略高于标准体重法。结论　徐州市儿童超重与肥胖的检出率均较高 ,但OOR均在可接受范围内 ;尽快实施有效干预措施可能控制或遏制儿童肥胖的高发趋势 ;新的儿童肥胖判断标准更符合实际 ,且便于操作。

The prevalence of childhood simple obesity in Xuzhou and a comparison between different diagnostic criteria

Objective To investigate the prevalence of childhood simple obesity in primary school and compare the conventional method of standard body weight to the new body mass index (BMI).Methods A multiple stage stratified cluster sampling was conducted among the grade 1-5 students in 25 primary schools of Xuzhou.Results The total prevalence of overweight and obesity and OOR (the ratio of overweight and obesity) was 13.3%, 17.4% and 0.8 with standard body weight and 12.2%, 11.3% and 1.1 with new BMI in 7-11 years old students. The prevalence with new BMI was lower than that with standard body weight (P<0.01), with its value of OOR being slightly higher than that of standard body weight. Conclusion The primary school students prevalence of overweight and obesity were rather high in Xuzhou, but the value of OOR was within the acceptable range and the high tendency may be controlled or held back by taking effective measures. The new BMI criteria of childhood overweight and obesity are more in accord with facts and easy to practice.
