Does the Severity of Overactive Bladder Symptoms Correlate With Risk for Female Sexual Dysfunction?

Abstract

Background: Several studies have associated overactive bladder (OAB) with female sexual dysfunction (FSD); however, there are no reports using a quantitative approach to measure OAB severity and to relate OAB to the risk of FSD.

Aim: To evaluate women with OAB and to correlate the severity of their urinary symptoms with their sexual function.

Methods: This cross-sectional study included 267 women older than 18 years with untreated OAB. All subjects completed the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) and the Female Sexual Function Index (FSFI).

Outcomes: Linear regression was used to analyze the association between variables and the numeric FSFI score, and categorical FSFI scores were analyzed using logistic regression. Spearman rank correlation coefficient was used to assess the correlation between ICIQ-OAB results and the different FSFI domains. The significance level was 5%.

Results: Subjects' mean age was 50.2 ± 11.9 years. Most women were married, had at least three children, and were postmenopausal (54.3%). Mean FSFI total score was 19.2 ± 9.8. For menopausal status, 65.6% of premenopausal women had a risk for FSD vs 86.2% of postmenopausal women. Mean ICIQ-OAB score was 10 ± 3.17. Postmenopausal women had the following risk factors statistically associated with sexual dysfunction: age, ICIQ score, and marital status. For these women, greater OAB severity, especially those with urgency and/or urge incontinence, was associated with worse scores in the arousal, lubrication, orgasm, and sexual pain domains. However, there was no statistically significant association for premenopausal women.

Clinical implications: Health professionals have to pay attention to OAB in women because of the greater risk for FSD in these patients.

Strengths and limitations: The strength was using a quantitative approach to measure OAB severity in a larger population. Limitations include a convenience sample with no power calculation; exclusion of women who did not have sexual intercourse in the past month; unmeasured distress caused by sexual disorders; and the impossibility of establishing causality between OAB and sexual dysfunction.

Conclusion: Women with OAB frequently have a risk for sexual dysfunction. In the postmenopausal group, women with scores indicating severe OAB had worse sexual function, mainly in the arousal, lubrication, orgasm, pain, and total domains.
