Study on relationship between benign prostatic hyperplasia and hypertension in rural elderly people

  Objective   To investigate the relationship between hypertension and benign prostatic hyperplasia(BPH)in rural elder people.

  Methods   Population-based survey and case-control study were conducted, 100 BPH patients, 100 non-BPH(excluding prostatic cancer and prostatitis)constituted case group and control group respectively.All subjects were over 60 years old and lived in same suburb of Shenyang.Test and non-conditional logistic regression were used for monovariate analysis and multivariate analysis respectively.

  Results   BPH prevalence rate was higher in hypertension group than that in normal group.There was a doseresponse relationship between BPH and diastolic pressure level.When other factors were adjusted diastolic pressure was still related to BPH(OR=1.10, 95% CI: 1.07-1.14), cigarette smoking(OR=0.660, 95% CI: 0.500-0.872), alcohol consumption(OR=0.650, 95% CI: 0.480-0.881).

  Conclusion   High diastolic pressure was probably a risk factors for BPH.
