Abstract

"Purpose: The National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) was used to determine the prevalence of prostatitis-like symptoms among young adult Korean males. Materials and Methods: From February 1, 2009 to February 1 2011, we conducted a survey targeting 1095 Korean young men who were enrolled at an educational institution. After explaining about NIH-CPSI, subject completed a questionnaire. Respondents were fairly evenly distributed. We analyzed the collected questionnaires, and considered men who reported perineal and/or ejaculatory pain or discomfort and a total NIH-CPSI pain score of ≥4 as having prostatitis-like symptoms. We also analyzed the correlations of pain, urinary symptom and quality of life scores in the prevalence group. Results: The average age of 1095 volunteers was 30.1 years (range 25-35 years). Among these men, 90 (8.2%) indicated feeling pain. Of these men, 27 experienced perineal and/or ejaculatory pain or discomfort, and their total NIH-CPSI pain score exceeded 4. The estimated prevalence of prostatitis-like symptoms was approximately 2.5%. The mean pain score of men who indicated experiencing pain was 7.0, but the mean pain score of all respondents was 0.7; the difference was statistically significant. Positive correlations were evident between pain score and quality of life score (Pearson's correlation coefficient=0.965), and urinary symptom score and quality of life score (Pearson's correlation coefficient=0.891). Also, using mean score of quality of life domain of ≤6 and >6 revealed statistically significant differences of mean score of pain (8.1/5.4) and urinary symptoms (2.6/0.3). Conclusions: The estimated prevalence of prostatitis-like symptom in the examined population of young adult Korean males was 2.5%. And there were closed relationships between pain, urinary symptome, and quality of life score in prevalence group."
