Objective:
To investigate the relation between various risk factors and benign prostatic hyperplasia (BPH).
Methods:
A population based case-control study was conducted, including 100 BPH patients over 60 years old living in suburb of Shenyang as study group, and 100 elderly men with non-BPH (excluding prostatic cancer and prostatitis) as control group. Chi(2) test and non-conditional logistic regression were used for monovariate analysis and multivariate analysis, respectively.
Results:
Data from monovariate analysis showed that BPH incidence was significantly related to body weight index, cigarette smoking, alcohol drinking, meal intake at the beginning of 1980's, hypertention and prostatitis, respectively. While multivariate non-conditional logistic analysis showed that BPH was related to five factors: prostatitis (OR = 5.577, 95% CI: 2.147 - 14.482), monthly intake of meats at the beginning of 1980's (OR = 4.930, 95% CI: 2.404 - 10.111), diastolic blood pressure (OR = 1.050, 95% CI: 1.017 - 1.083), cigarette smoking (OR = 0.660, 95% CI: 0.500 - 0.872) and alcohol consumption (OR = 0.650, 95% CI: 0.480 - 0.881).
Conclusion:
Prostatitis, monthly excessive intake of meats at the beginning of 1980's and high diastolic blood pressure were possible risk factors for BPH, while heavy cigarette smoking and alcohol consumption were possible protective factors for BPH.
