Prevalence and severity of urinary incontinence and associated factors in Iranian postmenopausal women: a cross-sectional study

Abstract

Abstract Background Urinary incontinence (UI) is one of the most common symptoms during menopause, leading to a decreased quality of life and limited social activities. This study aimed to determine the prevalence and severity of urinary incontinence and associated risk factors in postmenopausal women. Methods It was a cross-sectional study using cluster sampling on 433 postmenopausal women in Tabriz-Iran, 2021–2022. Data were collected using questionnaires of socio-demographic characteristics, Questionnaire for Urinary Incontinence Diagnosis (QUID), and International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UISF). Multivariate logistic regression was used to determine factors related to urinary incontinence. Results The overall prevalence of urinary incontinence was 39.5%; 20.6% stress urinary incontinence (SUI), 10.4% urgency urinary incontinence (UUI), and 8.5% mixed urinary incontinence (MUI). Multivariate logistic regression analysis showed that the prevalence of SUI (aOR 0.38; 95% CI 0.18–0.77) and UUI (aOR 0.38; 95% CI 0.15–0.94) was significantly lower in women with three childbirths than the ones with fewer childbirths. Also, the odds of UUI increased significantly in women at the 50–55 age range (aOR 3.88; 95% CI 1.16–12.93) than those less than 50 years. Conclusion Due to the high prevalence of urinary incontinence in postmenopausal women, caregivers should screen for early diagnosis and appropriate treatment of urinary incontinence to prevent its destructive impact on the quality of life.
