Association Between Sleep Duration and Urinary Incontinence in Female Adults: A Cross-sectional Study in National Health and Nutrition Examination Survey 2007-2018

Objective To elaborate on the effect of sleep duration on urinary incontinence (UI), we investigated the association between sleep duration with the risk of UI from the National Health and Nutrition Examination Survey (NHANES) dataset. Methods A cross-sectional survey of female participants aged 20 years old and above were enrolled from the year 2007-2018. We performed weighted multivariable logistic regression models to assess the association between sleep duration and UI. Results A total of 6838 female participants were included. Compared with sleep duration less than 6 hours, other sleep duration was found to be not significantly correlated with total UI, stress urinary incontinence, and mixed urinary incontinence in all three models Compared to sleep duration less than 6 hours, multivariate regression demonstrated that moderate sleep (6-8 hours) indicated a lower urgent urinary incontinence (UUI, odds ratio = 0.764, 95% confidence interval = 0.620-0.944, P = .013). Inadequate sleep (<6 hours) indicated a higher UUI (odds ratio = 1.308, 95% confidence interval = 1.060-1.614, P = .013) compared to moderate sleep duration (6-8 hours). The association might be modified by the family income-to-poverty ratio. Conclusion Inadequate sleep (<6 hours) was associated with a higher incidence of UUI. A moderate sleep duration (6-8 hours) was related to a lower rate of UUI. Further studies are warranted for clinical prevention and treatment guidance.
