摘要(Abstract)：

目的:探讨中老年人腰围、体质量指数(BMI)及腰身比(WHtR)对血脂异常的预测价值。方法:收集年龄≥30岁的行健康体检的中老年人665例,获取身高、体质量、腰围以及血脂水平等指标,计算BMI及WHtR;按血脂水平分组,比较血脂正常组和血脂异常组体检者的BMI、腰围以及WHtR,建立受试者工作特征曲线(ROC),确定腰围、WHtR、BMI判断血脂异常的灵敏度、特异度及最佳切点。结果:血脂异常组被检者的BMI、腰围、腰身均高于血脂正常组(P <0. 05),年龄在50～<60岁、BMI在24～28、WHtR≥0. 5、腹型肥胖体检者血脂异常患病率高; BMI诊断血脂异常的ROC曲线下面积大于腰围以及WHtR,男性BMI大于22. 36 kg/m2及女性BMI大于21. 65 kg/m2可作为判断血脂异常的危险因素。结论:与腰围和身高比相比,BMI更能准确预测血脂异常。
Objective: To investigate the predictive value of waistline,waist-to-height ratio and BMI on dyslipidemia in middle-aged and elderly people. Methods: Collecting 655 physical check report from middle-aged and elderly people over 30 years old. Height,BMI,waistline and blood lipid levels are used to calculate Body mass index( BMI) and waist-to-height ratio( WHT). Grouping by blood lipid level,BMI,waistline and waist-to-height ratio of dyslipidemia group was compared with the control group,then establishing receiver operating characteristic curve( ROC). According to the ROC curve,the sensitivity,specificity and the best tangent point were determined in waistline,waist-toheight ratio and body mass index. Results: Dyslipidemia group showed higher result in BMI,waistline and waist-to-height ratio than control group( P < 0. 05); patients aged 50 to over 60,BMI ranged from24 to 28,waist-to-height ratio ≥0. 5,abdominal obesity patients showed higher dyslipidemia morbidity rate; the area under the BMI diagnosed dyslipidemia ROC curves were bigger than waistline and waistto-height ratio: BMI as a biomarker to diagnose dyslipidemia when the BMI is over 22. 36 kg/m2 and21. 65 kg/m2 of males and females respectively. Conclusion: BMI is more sensitive to predicate dyslipidemia than waistline and waist-to-height ratio in middle-aged and elderly people.
