The epidemiological characteristics of benign prostate hyperplasia (BPH) in mainland China are not completely understood. We performed this meta-analysis to assess the prevalence of BPH from 1989 through 2014.
A total of 14 articles and 19 datasets were included. The pooled overall prevalence of BPH among men aged 40 years and older was 36. 6% [95% CI, 32. 3-44. 8]. The occurrence rate of BPH in the age groups 40-49 years, 50-59 years, 60-69 years, 70-79 years and 80 years and older was 2. 9%, 29. 0%, 44. 7%, 58. 1% and 69. 2%, respectively. The pooled occurrence rate of BPH was 41. 5% [95% CI, 34. 5-48. 4] in urban areas and 38. 6% [95% CI, 22. 7-54. 6] in rural areas; this difference in prevalence was not statistically significant [OR, 1. 51; 95% CI, 0. 97-2. 36]. BPH is highly prevalent in mainland China, and its prevalence increased with age. The trend in the prevalence of BPH in mainland China was not steady; the prevalence map based on a geographic information system (GIS) showed an unequal geographic distribution. High-quality surveys on BPH with a larger sample size are needed throughout mainland China to confirm these findings.
