摘　　要：目的:采用BMI、WC、WHtR和BF%分别对908名老年人进行肥胖筛检,以BF%肥胖评价结果为参照组,比较BMI、WC和WHtR三种方法和BF%在老年人肥胖筛检方面的一致性。方法:运用SPSS22.0,对BMI、WC、WHtR和BF%之间进行Pearson相关分析;采用Kappa检验比较BMI、WC、WHtR和BF%之间肥胖判定的可靠性;采用ROC曲线法对BMI、WC、WHtR和BF%之间肥胖判定的真实性进行比较。结果:(1)无论男女,BMI、WC、WHtR和BF%肥胖判断结果之间均呈中度相关关系。(2)BMI和BF%一致性最高(男性K=0.453、女性K=0.505、男女整体K=0.478);WHtR和BF%一致性最低(男性K=0.160、女性K=0.403、男女整体K=0.270)。(3)无论男女,BMI的ROC曲线下面积最大,(男性ROC=0.733、女性ROC=0.752、男女整体ROC=0.741);WHtR的ROC曲线下面积最小,(男性ROC=0.586、女性ROC=0.531、男女整体ROC=0.638)。(4)在预测肥胖方面WHtR敏感度高于BMI和WC,但特异度低于比BMI和WC。(5)无论男、女还是整体,BMI筛查肥胖的临界值均为24.95kg/m^(2),WC筛查肥胖的临界值男性为84.75cm,女性为82.20cm,整体为83.55cm,WHtR筛查肥胖的临界值男性为0.50,女性为0.56,整体为0.53。结论:综合BMI、WC和WHtR在筛查肥胖时的Kappa值、一致率、灵敏度、特异度、ROC曲线下面积和约登指数,在评判老年人群肥胖时,以健康为目标,BMI的肥胖判断效果最优,其次为WC和WHtR。Objective:To compare the consistency of BMI,WC,WHtR and BF%in 908 elderly people.Methods:spss22.0 software was used to analyze the Pearson correlation among BMI,WC,WHtR and BF%;kappa test was used to compare the reliability of obesity judgment among BMI,WC,WHtR and BF%;ROC curve method was used to compare the authenticity of obesity determination among BMI,WC,WHtR and BF%.Results:(1)there was a moderate correlation between BMI,WC,WHtR and BF%in both sexes.(2)BMI and BF%had the highest consistency(male k=0.453,female k=0.505,male and female overall k=0.478);WHtR and BF%had the lowest consistency(male k=0.160,female k=0.403,male and female overall k=0.270).(3)The results of ROC curve showed that the area under the ROC curve of BMI was the largest in both sexes(male ROC=0.733,female ROC=0.752,male and female overall ROC=0.741);WHtR had the smallest area under the ROC curve(male ROC=0.586,female ROC=0.531,male and female overall ROC=0.638).(4)WHtR is more sensitive than BMI and WC in predicting obesity,but its specificity is lower than that of BMI and WC.(5)Regardless of male,female or overall,the cut-off value of BMI screening for obesity is 24.95kg/m^(2),the cut-off value of WC screening for obesity is 84.75cm for men,82.20cm for women,and 83.55cm for the whole,and the cut-off value for WHtR screening for obesity Male is 0.50,female is 0.56,and overall is 0.53.Conclusion:the kappa value,concordance rate,sensitivity,specificity,area under ROC curve and yoden index of BMI,WC and WHtR in screening for obesity in elderly people,health is the target,followed by WC and WHtR.
