体脂肪率分布差异与高脂血症的关系及其筛检价值

The Influence and Screening Value of Different Distribution of Body Fat Percentage for Hyperlipidemia in Physical Examination People

目的:研究身体各脂肪率与高脂血症的关系及其筛检价值。方法:收集2015年5月~2016年5月福建省第二人民医院健康管理中心40~59岁体检者513例,检测体成分及血脂水平,采用受试者工作特征曲线(ROC)法分析身体各脂肪率对高脂血症的筛检率,以曲线下面积(AUC)表示。结果:男性上肢脂肪率与躯干脂肪率AUC均为0.64;BMI与BF%的AUC均为0.63;下肢脂肪率AUC为0.59,且95%置信区间不包含0.5。女性BF%与躯干脂肪率AUC均为0.56:BMI与上肢脂肪率AUC均为0.54;下肢AUC为0.53,但其95%置信区间包含0.5。结论:各指标对男性高脂血症均有一定筛检价值,其中上肢脂肪率和躯干脂肪率筛检价值最高,其次为BMI和BF%;女性各指标对高脂血症均无筛检价值。

Objective： To evaluate the relationship and screening value of fat rate in different body parts for hyperlipidemia in physical examination people. Methods： A total of 513 objects 40-59 years old people taking physical examination in the second people＇s hospital of Fujian province from May 2015 to May 2016 were included in this study. Values of body mass index （BMI）, body composition and blood lipid level were detected. The receiver operating characteristic curve （ROC） was used to analyze the screening rate of fat rate in different body parts and BF% on hyperlipidemia with sensitivity, specific and area under the curve （AUC）. Results： The screening accuracy rate on hyperlipidemia was higher for upper limbs and trunk body fat rate in male, AUC was 0.64. AUC of BMl and BF% were 0.63 and lower limbs＇ was 0.59. Conclusions： The upper limbs and trunk body fat rate were better screening indicators for hyperlipidemia compared with that ofBMI, BF% and lower limb body fat rate in male. There was no screening accuracy rate on hyperlipidemia in female. Men are suggested to do body composition tests to improve screening accuracy for hyperlipidemia.
