摘要:目的：研究成都地區中老年人群體重指數(BMI)與高血壓患病率及血壓水平的關系。方法:按照隨機抽樣的方法抽取樣本,對711人(平均年齡為63.28±6.25歲;男性占57.8%)進行了相關調查,調查內容中包括身高、體重、血壓及脈搏等。結果:成都地區中老年人群的超重及肥胖所占比重較大(約45%),按BMI分組(lt;18.5 kg/m2,18.5~23.9 kg/m2,24~27.9 kg/m2,≥28.0 kg/m2)的高血壓患病率分別是31.6%,54.8%,64.4%,82.8%,差異有統計學意義。采用logistic回歸分析發現在調整年齡、性別、腰圍及尿酸等后,BMI對高血壓的患病率有獨立影響。在整個人群及女性病人中,血壓隨著BMI的升高而有升高的趨勢,差異有統計學意義。結論:成都地區中老年人群超重及肥胖所占比重較大。BMI可以影響高血壓的患病率及影響女性病人的血壓水平,是高血壓的獨立危險因素。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 (Plt;0.01), and that was also seen in the level of SBP and DBP for the female (Plt;0.05). In logistic regression analysis adjusting for age, gender, waist, uric acid, the standardized OR for higher BMI (≥28.0 kg/m2) 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.
