目的探讨中老年男性高血压人群中,国际前列腺增生症状评分(IPSS)和最大尿流率(Qmax)的影响因素。方法对安徽安庆农村地区50～75岁男性原发性高血压患者435例进行流行病调查,采用多元Logistic回归分析IPSS和最大尿流率的影响因素。结果多元Logistic回归分析结果显示:影响中老年男性高血压患者IPSS评分的主要因素有年龄(OR2.25,95%CI=1.45～3.48)和残余尿量(OR2.98,95%CI=1.92～4.63),影响最大尿流率的主要因素有年龄(OR2.22,95%CI=1.43～3.45),前列腺体积(OR2.39,95%CI=1.42～4.04),残余尿量(OR2.09,95%CI=1.34～3.25)和吸烟(OR0.56,95%CI=0.31～0.99)。结论在中老年男性高血压患者人群中,年龄和残余尿量是良性前列腺增生主观症状的主要影响因素;年龄、前列腺体积以及残余尿量是最大尿流率的主要影响因素;吸烟可能是最大尿流率减小的保护因素。
Objective To investigate the influencing factors of IPSS and Qmax in middle-aged and elderly hypertensive population. Methods An epidemiological survey of 435 essential hypertension patients aged 50-75 years in rural areas of Anqing, Anhui province was carried out. Multivariate Logistic regression analysis was used to analyze the influencing factors of IPSS and maximum uroflow rate. Results The results of multivariate logistic regression analysis showed that the main factors affecting the IPSS score of middle-aged and elderly hypertensive patients were age (OR2.25,95% CI = 1.45-3.48) and residual urine volume (OR2.98,95% CI = 1.92 ~ 4.63). The main factors influencing the maximum uroflow rate were age (OR2.22, 95% CI = 1.43-3.45), prostate volume (OR2.39, 95% CI = 1.42-4.04), residual urine volume , 95% CI = 1.34-3.25) and smoking (OR 0.56, 95% CI = 0.31-0.99). Conclusion Age and residual urine volume are the main influencing factors of subjective symptoms of benign prostatic hyperplasia in the population of middle-aged and elderly male patients with hypertension. Age, prostate volume and residual urine volume are the main influencing factors of maximal uroflow rate. Smoking may be the largest urine Reduced flow rate of the protection factor.
