Abstract

PURPOSE
To estimate the influences of pain and urinary symptoms on quality of life and determine the item that has the most predicting ability for quality of life in young men with chronic prostatitis-like symptoms.
MATERIALS AND METHODS
Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. of 28,841 men aged 20 years dwelling in the community, 16,321 men(a response rate 56.6%) completed self-administered questionnaires. A total of 1,057men who complained symptoms suggestive of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined by the logistic regression analysis. The receiver operating characteristic(ROC) curve was used to provide the predicting ability of each item quality of life.
RESULTS
In multivariate analysis, pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, and pain contributed more than urinary symptoms. Among items of pain and urinary symptoms, pain severity had the most predicting ability for impact, overall quality of life and quality of life impact domain. The areas under the ROC curves for impact, overall quality of life and quality of life impact domain were 71.3%, 69.3% and 67.0%, respectively.
CONCLUSIONS
Urinary symptoms as well as pain may be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influencing factor for quality of life in this population.
