摘　　要：目的探讨体重指数（BMI）、腰围（WC）与三酰甘油水平之间的关系，并用受试者工作特征（ROC）凹线评价BMI和WC对诊断高三酰甘油血症的价值。方法以2008年7至9月在我院进行常规体检的1093人（男性707人、女性386人）为研究对象，检测身高、体重、腰围和血三酰甘油水平。比较三酰甘油正常组与异常组BMI和WC的差异。建立BMI和WC的ROC曲线，获得曲线下面积及曲线上各界值点的灵敏度和特异度。结果男女性三酰甘油异常率分别为33．5％和8．3％。三酰甘油异常者的BMI和WC明显大于三酰甘油正常者（P〈0．01）。以BMI诊断高三酰甘油血症的ROC曲线下面积：男性为0．728±0．041、女性为0．708±0．021，最佳界值点：男性为24．5、女性为22．5；以WC诊断高三酰甘油血症的ROC曲线下面积：男性为0．790±0．042，女性为0．714±0．020，最佳界值点：男性为86cm，女性为77cm。结论BMI和WC与三酰甘油水平均相关。BMI和WC是预测高三酰甘油血症较为理想的指标。Objective To explore the association between body mass index （BMI） /waist circumference （WC） and blood triglyceride （TG） level in adults. To evaluate the value of the BMI and WC in diagnosing the hy- pertriglyceridemia by the receiver operating characteristic （ROC） curve. Methods A total of 1 093 adults （707 men and 356 women） were examined in our hospital from July to September in 2008. Height, weight, WC and blood triglyceride were measured and analyzed. The ROC curve was drawn to evaluate the sensitivity and specificity of the threshold values. Results The hypertriglyceridemia rate was 33.5% among men and 8.3% among women. The BMI and WC of hypertriglyceridemia group were significantly higher than those of normal TG group for both men and women （ P 〈 0. 01 ）. The area under ROC curve was 0. 728± 0. 041 for men and 0. 708 ±0. 021 for women when using BMI to predict hypertriglyceridemia. The optimal threshold value was 24. 5 for men and 22. 5 for women. The area under ROC curve was 0. 790 ±0. 042 for men and 0. 714 ±0. 020 for women when using WC to predict hypertrig-lyeeridemia. The optimal threshold value was 86 em for men and 77 cm for women. Conclusions Both BMI and WC are associated blood triglyceride level. WC and BMI are useful parameters in predicting hypertriglyeeridemia.
