通辽市牧区蒙古族居民体质指数、腰臀比与血压水平的关系

目的了解通辽市牧区蒙古族居民体质指数（BMI）、腰臀比（WHR）与血压水平之间的关系。方法采用整群随机抽样的方法，抽取该市蒙古族相对集中的4个嘎查（村）居民1108名，进行现场询问和体格检查。结果该人群超重率、肥胖率、腹型肥胖率、高血压患病率依次为31．4％，15．5％，40．1％，47．65％。腹型肥胖时其1、2、3级高血压患病率显著升高（P〈0．05）：超重、肥胖、腹型肥胖者患高血压的危险分别是相对正常人群的1．2、1．6、1．7倍；血压水平随着BMI、WHR增大而升高：BMI和WHR均正常、BMI异常WHR正常、BMI正常WHR异常、BMI和WHR均异常时高血压患病率分别为37．80％，20．69％，44．62％，65．35％，其RR值分别为1．0，0．6，1．2，1．7。结论BMI和WHR与血压水平密切相关，预防与控制超重、肥胖和腹型肥胖应成为防治通辽市牧区蒙古族居民高血压的重要措施。

The Study on the Relationship of Hypertension with BMI and WHR in Mongolian Residents of Rural Districts in Tongliao

Objective To understand the realationship of hypertention with body mass index （BMl）and waist hips ratio （WHR）in mongolian residents of grazing districts in Tongliao. Methods 1 108 rural residents （aged≥30 yrs） were randomly selected with the cluster sampling from 4 rural areas of 4 districts in Tongliao city, and they were investigated with questionnaire and the body measurement. Results The detection rates of the overweight, obesity, central obesity and hypertention were 31.4%, 15.5%, 40.1% and 40.6%; The prevalence rates of grade 1 to 3 hypertention were highly increased （P〈0.001） among central obesity people. The main risk factors of high blood pressure were overweight, obesity and central obesity, their RR values were 1.2, 1.6 and 1.7. The level of blood pressure was increased with BMI and WHR increasing, and WHR had much more influence. Under the circumstance of normal BMI and WHR, abnormal BMI and normal WHR, normal BMI and abnormal WHR, or abnormal BMI and WHR, the prevalence rates of hypertension were 37.80%, 20.69%, 44.62% and 65.35%, respectively, and their RR values were 1.0, 0.6, 1.2 and 1.7. Conclusion Overweight, obesity and central obesity were main risk factors for the health of rural residents of the Mongolian in Tongliao, and the prevention and control of overweight and obesity are the focus of hypertension prevention.
