Vitamin D and Incident Urinary Incontinence in Older Adults

The aim of this study is to determine whether vitamin D status is associated with incident urinary incontinence (UI) among community-dwelling older adults. The University of Alabama at Birmingham Study of Aging is a prospective cohort study of community-dwelling Medicare enrollees. Standardized assessment of UI was conducted using the validated Incontinence Severity Index. The analysis of 25-hydroxyvitamin D [25(OH)D] levels was performed on stored baseline sera. UI was assessed every 6–12 months for up to 42 months. The analyses included multivariable logistic regression and Cox proportional hazard models. Of 350 participants (175 male, 147 black, mean age 73.6±5.8), 54% (189/350) were vitamin D deficient (25(OH)D
