Abstract: Objective To investigate the prevalence of benign prostatic hyperplasia(BPH)in hyper tensive populations and the risk factors for BPH in rural community.Methods Apopulation-based epidemiological investigation was conducted to collect 621 hypertensive male patients over 50 years old who are local residents in Anqing,Anhui.In this population,300 subjects coincided with BPH and another 321 subjects did not.Logistic regression was used for analysis of risk factors of BPH.T test,χ² test,and stepwise Logistic regression were used for univariate analysis and multivariate analysis,respectively.Results Logistic regression analysis showed that BPH was related to five major risk factors:age(OR=1.077,95%CI:1.046~ 1.109),sexual intercourse frequence in 30 years old(OR=1.027,95%CI:1.004~1.051),monthly salt intake(OR= 2.007,95%CI:1.324~3.043),weekly fruits intake(OR=0.628,95%CI:0.431~0.914),mental tensity(OR= 2.128,95%CI:1.439~3.146).Conclusion Age,hig h sexual intercourse frequence in 30 years old,high salt intake,mental tensity were possible risk factors for BPH,w hile heavy fruits intake was possible protective factor.
