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 (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/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.
