不同肥胖评价指标对运动不足肥胖老年人高血压患病风险的预测研究

A Study on the Prediction of the Risk of Hypertension in Obese Elderly People with Insufficient Exercise by Different Obesity Evaluation Indicators

目的:比较不同肥胖评价指标对运动不足肥胖老年人高血压患病风险的预测效果,找出不同肥胖评价指标预测运动不足肥胖老年人群高血压患病的切点值,为该群体高血压的早期预防和控制提供参考。方法:采用身体质量指数(BMI)、体脂含量(BFP)、腰围(WC)和腰身比(WHtR)四种肥胖指标,组别间率的比较采用卡方(X^(2))检验;二元Logistic回归分析不同肥胖评价指标对运动不足高血压患病风险的预测作用;绘制受试者工作特征曲线(ROC),通过曲线下面积(AUC)判断各肥胖指标对该群体高血压的预测价值,并通过计算约登指数找出不同肥胖评价指标预测运动不足肥胖老年人群高血压患病的切点值。结果:(1)随着年龄的增加,各肥胖评价指标高血压患病率均呈现上升趋势。(2)BFP在预测运动不足肥胖男女老年群体高血压患病风险时均为最佳预测指标。(3)各肥胖评价指标预测运动不足肥胖老年高血压患病风险时的切点值为:男性BFP≥26.85%、女性BFP≥36.45%时,高血压患病风险增加;男性WHtR≥0.53、女性WHtR≥0.58时,高血压患病风险增加;男性WC≥89.15cm、女性WC≥85.10时,高血压患病风险增加;男性BMI≥25.05 kg/cm^(2)、女性BMI≥26.15 kg/cm^(2)时,高血压患病风险增加。结论:四种肥胖评价指标均能有效预测高血压,预测能力男女群体均为:BFP>WHtR>WC>BMI。建议定期进行健康检查,早期发现和通过运动控制肥胖的发生,降低老年人患高血压概率。

Purpose:This study to compare the predictive effects of different obesity evaluation indicators on the risk of hypertension in obese elderly people,and to find out the cut-point values of different obesity evaluation indicators to predict hypertension in obese elderly people,so as to provide a reference basis for the early prevention and control of hypertension.Methods:Four obesity indicators were measured by body mass index(BMI),body fat proportion(BFP),waist circumference(WC)and waistto-body ratio(WHtR),and the rate comparison was measured by chi-square(X^(2));By calculating the Yoden index,the tangent point values of different obesity evaluation indicators predicted the prevalence of hypertension in obese elderly people.Results:(1)With the increase of age,the prevalence of hypertension in all obesity evaluation indicators showed an upward trend.(2)BFP is the best predictor of the risk of hypertension in obese men and women in the elderly.(3)The cut point value when predicting the risk of hypertension in obese elderly people was:the risk of hypertension increased when BFP≥26.85%in men and BFP≥36.45%in women;the risk of hypertension increased when WHtR≥0.53 in men and WHtR≥0.58 in women;the risk of hypertension increased when the WC≥89.15cm in men and the WC≥85.10cm in women,and the risk of hypertension was increased in men’s BMI≥25.05kg/cm^(2),and the BMI≥26.15kg/cm^(2) in women.Conclusion:Four obesity evaluation indicators can effectively predict hypertension,and the predictive ability is BFP>WHtR>WC>BMI in both male and female groups.It is recommended to conduct regular health checks to detect and control the occurrence of obesity early and reduce the chance of hypertension in the elderly.
