Objective: To investigate the prevalence and associated factors of lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) in Chinese aging males.
Method: 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.
Results: 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).
Conclusions: 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.
