title: Community-based research on the benign prostatic hyperplasia prevalence rate in Korean rural area.
abstract: OBJECTIVE
  We investigated the prevalence rate of benign prostatic hyperplasia (BPH) among Korean males in a rural area through a cross-sectional, community-based epidemiologic survey and analyzed the correlation with epidemiologic factors.
  
  
  METHODS
  A total of 779 males who lived in Yangpyeong County participated in a prostate examination campaign. Targeting these men, we collected the International Prostate Symptom Score (IPSS), medical history, demographic information, serum prostate-specific antigen, and prostate volume as measured by transrectal ultrasonography. The data for 599 participants were analyzed, excluding 180 men who had a possibility of prostate cancer. BPH was defined as an IPSS of 8 points or higher and a prostate volume of 25 mL or more.
  
  
  RESULTS
  The prevalence rate of BPH was 20.0%. The prevalence rate increased with age. There were 2 subjects (4.4%) in the age group of 40-49 years, 18 subjects (10.9%) in the age group of 50-59 years, 44 subjects (22%) in the age group of 60-69 years, and 56 subjects (26.6%) in the age group of over 70 years; this increase with age was statistically significant (p<0.001). In the BPH group, the average IPSS was 14.67±5.95, the average prostate volume was 37.04±11.71 g, and the average prostate-specific antigen value was 1.56±0.88 ng/mL. In the analysis of correlations between the epidemiologic factors and the risk of BPH, smoking was the only statistically significant factor.
  
  
  CONCLUSIONS
  The total prevalence rate of BPH in this study was 20.0%, which was a little lower than the rate reported in other cities or rural areas.
