摘要
目的寻找简便易行的筛查肥胖的新指标。方法以体质指数(BMI)作为肥胖的诊断标准,本研究将2 423名新疆喀什农村维吾尔族妇女的BMI指数与腰围、臀围、腰臀比、腰围身高比进行了比较。用方差分析、Pearson相关分析进行统计学描述,用ROC曲线寻找筛查肥胖的最佳测量学指标及其切点值。结果 (1)农村维族妇女的BMI为(24.8±3.7)kg/m2,超重率和肥胖率分别高达31.9%和18.5%,均高于汉族妇女的超重率(22.8%)和肥胖率(7.1%)(P<0.05);腰围、腰臀比、腰围身高比超标率分别为31.4%、37.9%和57.0%。(2)年龄、BMI、腰围、臀围、腰臀比、腰围身高比之间的两两比较均呈正相关,而臀围与BMI相关性最高(相关系数r=0.82)。教育程度分别与腰围、臀围、腰臀比、腰围身高比、BMI呈负相关,与人均日收入呈正相关。(3)臀围预测肥胖的AUC和YI值分别为0.953和0.813,均高于其它预测指标,肥胖者筛查切点值:臀围>101.5 cm。结论臀围、腰围身高比、腰围预测肥胖均有较好的初筛价值;臀围初筛超重、肥胖效果最佳(AUC、YI均最大)。
Objective To investigate a new,simple and convenient indicator for obesity screening.Methods Body mass index( BMI) was regarded as the diagnostic standard for obesity in this study. The BMI of 2 423 Uyghur rural women living in Kashi Prefecture,Xinjiang region were compared with their waist circumference,hip circumference,waist-to-hip ratio,and waist-to-height ratio. Variance analysis and Pearson correlation analysis were used for statistical analyses,and receiver operative characteristic( ROC) curve was employed to define the optimal measurement index and its cutoff values for diagnosing obesity. Results1 The enrolled subjects had an average BMI of 24. 8 ± 3. 7 kg/m2,with a rate of overweight as 31. 9% and of obesity as high as 18. 5%,both higher than the rates of overweight( 22. 8%) and obesity( 7. 1%) among Han females( P < 0. 05),respectively. The abnormalities in the Uyghur females were very high in waist circumference( 31. 4%),waist-to-hip ratio( 37. 9%) and waist-to-height ratio( 57. 0%),respectively.2There were positive correlations between any 2 of the following indicators: age,BMI,waist circumference,hip circumference,waist-to-hip ratio and waist-to-height ratio,and the most significant correlation was seen between BMI and hip circumference( r = 0. 82). Education level was negatively correlated with BMI,waist circumference,hip circumference,waist-to-hip ratio and waist-to-height ratio,respectively,but positively correlated with per capita income/per day. 3 In the prediction of obesity,hip circumference showed thehighest values of area under curve( AUC,0. 953) and YI( 0. 813) among all indicators tested,obviously higher than other indicators. In terms of predicting obesity, the cutoff value of hip circumference was> 101. 5 cm. Conclusion Hip circumference,waist-to-height ratio and waist circumference are of good value in prediction of preliminary screening obesity. Hip circumference has the best predictive effect in screening overweight and obesity( with highest AUC and YI values).
