Coital urinary incontinence: impact on quality of life as measured by the King’s Health Questionnaire

The aim of this present study was to measure the impact of coital urinary incontinence (UI) on sexually active women quality of life (QoL). Epidemiological, observational, cross-sectional, and multicenter study including 633 sexually active women seeking treatment for UI and/or overactive bladder in a gynecological clinic, aged between 24 and 83 years. All women filled out the King’s Health Questionnaire—KHQ. With this questionnaire, we had a complete register of the different urinary symptoms, included coital UI, and the extent of how they affect patient’s life and the measurement of impact on the patient’s QoL by the KHQ score. Prevalence of coital incontinence in sexually active women was 36.2%, classifying this impact as low (59.8%), moderate (32.3%), and high (7.9%). Women reporting coital incontinence had similar mean age and body mass index (BMI) to those women without coital incontinence. Women with coital incontinence had higher scores (worse QoL) in all the dimensions and in the KHQ global score (p < 0.05). Coital incontinence was the only variable showing an independent relation to KHQ global score (B = 10.1; 95% confidence interval = 1.7–18.6) in a multiple regression model adjusted to age, BMI, and the other urinary symptoms under study. One third of the sexually active women with urinary symptoms had coital incontinence. Among sexually active women with urinary symptoms, patients with coital urinary incontinence had a higher impact on their QoL than those without coital incontinence. Coital incontinence is independently related to a KHQ high score, which suggest worse QoL.
