Purpose: To explore the association between bladder pain syndrome/interstitial cystitis (BPS/IC) and the risk of subsequent healthcare-seeking behavior for common mental disorders in Taiwan using a population-based administrative database.
Materials and methods: Both BPS/IC subjects and their age- and sex-matched non-BPS/IC control subjects who had no previous insomnia and mental diseases, including anxiety, depression, were subsequent serviced for these mental disorders by psychiatrists from the recruited date between 2002 and 2010. The risk of outcomes was assessed with Kaplan–Meier curves; and the impact of BPS/IC was estimated with Poisson regression analysis and Cox proportional hazards models.
Results: We included 16,185 BPS/IC subjects and 32,370 non-BPS/IC subjects, with a mean age of 46 years and 73.5 % of women. Difference of the prevalence of hypertension, diabetes, chronic kidney disease, and hyperlipidemia between groups was not significant difference. Subjects with BPS/IC had a significant higher incidence rate of anxiety, depression, and insomnia than the matched controls (92.9 vs 38.4, 101.0 vs 42.2, 47.5 vs 23.0; per 10,000 person-year). After adjusting for age, sex, and common comorbidities in multivariable analysis, BPS/IC remained a significant predictor with hazard ratio and 95 % confidence incidence, 2.4 (2.2–2.7), 2.4 (2.2–2.6), and 2.1 (1.8–2.4) for anxiety, depression, and insomnia, respectively.
Conclusion: Patients with BPS/IC are at risk of development of anxiety, depression, and insomnia. These findings can help guide urologists, urogynecologists, and psychiatrists toward early identification and treatment of psychological complications that may develop in BPS/IC patients.
