Abstract: Objective: To estimate the prevalence, risk factors, severity, morbidity, and outpatient rate of women urinary incontinence (UI). Methods: A stratified multiple-stage cluster sampling method was used to recruit female adults in Yuxi. Totally 5523 participants were investigated using the ICI-Q-SF and I-QOL. Results: Among the 5523 participants, the prevalence of any UI was 10.74%. The most common subtype was stress incontinence, with a prevalence of 4.38%, followed by urge incontinence,with a prevalence of 2.97%. Age and marry early were independently predicted UI. We found that 51.94% of women with UI reported daily leakage, and 45.03% women reported UI had moderate to severe impact on their daily life. Only 15.68% of women with UI had consulted a doctor. Conclusion: The prevalence of UI in Yuxi was lower than that in the developed countries, however,the UI women affected confronted with daily leakage which impacted their daily lives severely and few obtained medical advice.
