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(<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。
Objective: To study the relationship between body mass index (BMI) and the prevalence of hypertension and blood pressure in middle-aged and elderly people in Chengdu. Methods: A total of 711 people (mean age, 63.28 ± 6.25 years; 57.8% of men) were sampled according to a random sampling method. The survey included height, weight, blood pressure and pulse rate. Results: The proportion of overweight and obesity in middle-aged and elderly people in Chengdu was relatively high (about 45%). According to the BMI group (<18.5 kg / m ~ 2,18.5-23.9 kg / m ~ 2,24 ~ 27.9 kg / 2, ≥28.0 kg / m ~ 2) were 31.6%, 54.8%, 64.4% and 82.8% respectively, the difference was statistically significant. Using logistic regression analysis found that after adjusting for age, gender, waist circumference and uric acid, BMI had an independent impact on the prevalence of hypertension. In the entire population and female patients, blood pressure increased with the rise of BMI, the difference was statistically significant. Conclusion: The proportion of overweight and obesity among middle-aged and elderly people in Chengdu is larger. BMI can affect the prevalence of hypertension and affect the blood pressure of female patients, which is an independent risk factor for hypertension.
