Health-related quality of life and sexual function among women with overweight or obesity and urinary incontinence: a cross-sectional study

To assess the health related quality of life (HRQoL) and sexual function related to urinary incontinence (UI) severity among women with overweight or obesity.

From September 2023 to January 2024, a cross-sectional was conducted among women seeking weight loss with overweight or obesity focusing on the symptoms and effects of UI. The degree of UI severity, UI-specific HRQoL, sexual function, and generic HRQoL were detected via Incontinence Modular Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), Incontinence Impact Questionnaire-Short Form (IIQ-7), Short-form Prolapse Incontinence Sexual Questionnaire (PISQ-12), and European Quality of Life-5 Dimensions 5-Level questionnaire (EQ-5D-5 L) respectively.

Out of 1205 valid responses, 564 (46.8%) reported UI with 354 classified as mild, 179 as moderate, and 31 as severe based on ICIQ-UI-SF scores. The mean age and body mass index of the respondents were 36.65 years and 29.9 kg/m², respectively. Individuals with more severe symptoms of UI exhibited correspondingly lower levels of UI-specific HRQoL, sexual function, and generic HRQoL. Although the correlations were weak, the severity of UI symptoms measured by ICIQ-UI-SF and IIQ-7 were significantly correlated with the mean utility values (r=-0.335, and − 0.351, P<0.001) of EQ-5D-5 L especially in the domains of anxiety/depression symptoms (r = 0.339 and 0.322, P<0.001).

Nearly half of women seeking weight loss with overweight or obesity may experience UI, which significantly affects HRQoL and sexual function. The severity of UI symptoms is significantly correlated with the generic HRQoL measured by EQ-5D-5 L, especially in the domain of anxiety/depression symptoms.
