摘要:目的：研究成都地区中老年人群体重指数(BMI)与高血压患病率及血压水平的关系。方法:按照随机抽样的方法抽取样本,对711人(平均年龄为63.28±6.25岁;男性占57.8%)进行了相关调查,调查内容中包括身高、体重、血压及脉搏等。结果:成都地区中老年人群的超重及肥胖所占比重较大(约45%),按BMI分组( lt;18.5 kg/m2,18.5~23.9 kg/m2,24~27.9 kg/m2,≥28.0 kg/m2)的高血压患病率分别是31.6%,54.8%,64.4%,82.8%,差异有统计学意义。采用logistic回归分析发现在调整年龄、性别、腰围及尿酸等后,BMI对高血压的患病率有独立影响。在整个人群及女性病人中,血压随着BMI的升高而有升高的趋势,差异有统计学意义。结论:成都地区中老年人群超重及肥胖所占比重较大。BMI可以影响高血压的患病率及影响女性病人的血压水平,是高血压的独立危险因素。
Abstract: Objective: To investigate the effects of body mass index on prevalence of hypertension and blood pressure in the elderly. MethodsA survey, including height, weight, blood pressure and pulse, was carried out in a general population of Chengdu. A total of 711 subjects (average age: 63.28±6.25 years; male: 57.8%) were recruited by random sampling method. Results：The proportion of overweight and obesity was about 45%. The hypertension prevalence rate was significantly positively correlated with BMI (P lt;0.01), and that was also seen in the level of SBP and DBP for the female (P lt;0.05). In logistic regression analysis adjusting for age, gender, waist, uric acid, the standardized OR for higher BMI (≥28.0 kg/m2) as a risk factor of hypertension was 5.140. Conclusion：The proportion of overweight and obesity was great in Chengdu area. BMI can affect the prevalence rate of hypertension and the level of blood pressure.
