[Epidemiological study of chronic prostatitis patients with depression symptoms]

To study the depression symptoms in chronic prostatitis (CP) patients, and explore the correlation between depression symptoms and CP.

The Zung self-rating depression scale (SDS) , NIH-CPSI, IIEF-5, and a self-designed questionnaire were employed in 1500 cases of CP patients.

A total of 1426 effective questionnaires were collected. The mean score of SDS was (44.24 +/- 10.20), significantly higher than that of the domestic norm (P = 0.000). With the score limitation set at > or = 53, 309 (21.7%) of the CP patients had symptoms of depression, of whom 176 (12.3%) were rated by SDS as in the mild, 114 (8.0%) in the moderate and 19 (1.3%) in the severe state of depression. The dominating symptoms as listed in SDS were exactly the stimulating and provoking factors of CP. The scores of SDS were significantly correlated with disease course, CPSI score, IIEF score and times and cost of treatment (P < 0.01), while no correlation was observed with age and WBC counts in EPS.

CP patients mostly have depression problems, which are closely correlated with CP and contribute to the recurrence, refractoriness and discontinued outcome of the disease.
