Association between chronic prostatitis/chronic pelvic pain syndrome and anxiety disorder: a population-based study.

BACKGROUND

This case-control study utilized a population-based dataset to examine the association of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with prior anxiety disorder (AD) by comparing the risk of prior AD between subjects with CP/CPPS and matched controls in Taiwan.

METHODS

We study used data sourced from the Taiwan Longitudinal Health Insurance Database. The cases comprised 8,088 subjects with CP/CPPS and 24,264 randomly matched subjects as controls. We used a conditional logistic regression to calculate the odds ratio (OR) for having been previously diagnosed with AD between subjects with and without CP/CPPS.

RESULTS

Of the 24,264 sampled subjects, 2309 (7.1%) had received an AD diagnosis before the index date; AD was found in 930 (11.5%) cases and 1379 (5.7%) controls (p<0.001). The conditional logistic regression analysis revealed that compared to controls, the OR for prior AD among cases was 2.10 (95% CI = 1.92∼2.29, p<0.001) after adjusting for diabetes, hypertension, hyperlipidemia, and sexually transmitted diseases. Our results show that CP/CPPS was consistently and significantly associated with prior AD in all age groups (18∼39, 40∼59, and >59 years). In particular, subjects aged 40∼59 years had the highest adjusted OR (of 2.53) for prior AD among cases compared to controls.

CONCLUSIONS

We concluded that CP/CPPS is associated with previously diagnosed AD. Urologists should be alert for the association between CP/CPPS and AD in subjects suffering from AD.
