The prevalence and associated factors of lower urinary tract symptoms suggestive of benign prostatic hyperplasia in aging males

To investigate the prevalence and associated factors of lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) in Chinese aging males.Data downloaded from the China Health and Retirement Longitudinal Study (CHARLS) was subjected to descriptive statistics followed by univariate logistic regression and multivariate logistic regression.A total of 8563 participants with an overall LUTS/BPH prevalence of 11.97% were enrolled. With aging, the LUTS/BPH prevalence increased (p < 0.001). Men aged over 70 years suffered the highest prevalence of 22.70%. Marital status did nothing to the suffering of LUTS/BPH. Subjects receiving more education or assessed as depression displayed higher incidence of LUTS/BPH (p < 0.001). In rural villages, settlers showed lower prevalence of 10.00% compared to 16.49% for urban residents. Smoking, sleeping time and alcohol consumption seemed to play a protective role in the occurrence of LUTS/BPH. One who slept more than 8 h, was smoking, and drank more than once a month had the lowest prevalence (p ≤ 0.001).For Chinese aging population, LUTS/BPH prevalence increased with aging and was interfered by educational level, depression, sleeping time, geographical region, smoke and alcohol consumption.
