云南省三种民族肥胖现状及利用ROC曲线对高血压进行预警研究

Study on obesity status among three minorities and study of hypertension alerting by using ROC curve

[目的]通过对迪庆州三种民族肥胖现状的分析,并绘制ROC曲线,用调查对象的腰围(WC)、体质指数(BMI)对高血压进行预警,为高血压的早期防控提供依据。[方法]通过多阶段分层随机抽样获得调查对象,用问卷调查和身体测量、血压测量对符合条件的迪庆州常住居民开展调查。Epidata 3. 0进行数据双录入,SPSS18. 0进行统计分析。[结果] 1379名藏族中肥胖218人(15. 8%),577名傈僳族中肥胖24人(4. 2%),820名纳西族中肥胖97人(7. 0%),三种民族间的肥胖比例差异有统计学意义(χ2=116. 47,P <0. 05)。藏族腹型肥胖544人(39. 4%)、傈僳族腹型肥胖88人(15. 3%)、纳西族腹型肥胖202人(24. 6%),藏族肥胖、腹型肥胖比例最高(P <0. 05)。高血压患病1094人,患病率为30. 5%。超重、肥胖、腹型肥胖是高血压的危险因素(OR=2. 147、4. 240、2. 066,P <0. 05)。可选用BMI、WC对高血压进行预警(AUC> 0. 5,P <0. 05)。藏族WC和BMI的切点值最大,分别为78. 5、26. 0。[结论]三种民族中,藏族肥胖和腹型肥胖比例最高,运用WC、BMI这两个简单指标预警高血压既简便又可行,对于早期开展高血压的预防与控制具有重要意义。

Objective Through analyzing obesity status of three minorities in Diqing,and drew ROC curve for waist circumference(WC) and BMI to alert the risk of hypertension,so as to provide basis for early prevention and control of hypertension. Methods Respondent was through multi stage stratified random sampling. It used questionnaire,physical and blood pressure measurement for eligible inhabitants in Diqing. Epidata 3.0 was used to enter data and SPSSl8.0 was for statistical analysis. Results There were 218(15.8%) obesity person in 1379 Tibetans,24(42%) obesity person in 577 Lisu people,97(7.0%) obesity person in 820 Naxi people. There was statistical significance in obesity proportion difference among three minorities(χ^2=116.47, P <0.05). There were 544(39.4%) abdominal obesity person in Tibetan,88(15.3%) were in Lisu people,and 202(24.6%) were in Naxi people. The proportion was the highest of abdominal obesity in Tibetan( P <0.05). There were 1094 hypertension patients,prevalence was 30.5%. Overweight,obesity,and abdominal obesity were the risky factors of hypertension(OR=2.147,4.240,2.066, P <0.05). Tangent point value of BMI and WC of Tibetan were the highest which was 78.5 and 26.0 respectively. Conclusions Among three minorities,the proportion is the highest of abdominal obesity in Tibetan. It is simple and feasible to use WC and BMI to alert the risk of hypertension,and has significant for early prevention and control of hypertension.
