To take a different perspective in assessing young men with chronic prostatitis-like symptoms, this study was designed since few prospective studies are available to survey a population of young men.
One hundred and fifty men aged 20 years dwelling in the community were randomly selected. Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index and the selfreported scores for pain and urinary symptoms were used to identify chronic prostatitis-like symptoms. The psychological methods used were the Beck Depression Inventory, the State-Trait Anxiety Inventory, and the Bem Sex Role Inventory. A total of 87 men (a response rate 58%) completed self-administered questionnaires.
As the scores for pain and urinary symptoms increased, those for depression increased (p < 0.001 and p = 0.01, respectively). However, the mean scores for state and trait anxiety were not different according to the scores for pain and urinary symptoms. The mean masculinity scores were not different according to the scores for pain but those were significantly different according to the scores of urinary symptoms (p = 0.042). The mean femininity scores were not different according to the scores of pain and urinary symptoms.
Our findings suggest that psychological factors, especially depression and weak masculine identity may be associated with an early stage of chronic prostatitis-like symptoms. Young men with chronic prostatitis-like symptoms also have psychological problems.
