Weight loss and physical activity are associated with decreased risk of UI in men, but it is unclear how specific differences in body composition and strength affect UI, or whether UI is reversible with changes in these factors in older age. We evaluated prospective relationships between body composition, muscle strength, and non-neurogenic urinary incontinence in older men. METHODS Our study sample included 1455 community-dwelling men, age 70 to 79, in the multicenter Health, Aging, and Body Composition study. UI was assessed using structured questionnaires. Body composition and muscle strength were assessed by physical exam, performance testing, and dual-energy X-ray absorptiometry. We used multivariate logistic regression to evaluate associations between baseline body composition, strength measures, and monthly UI. We also evaluated associations between changes in body composition or strength measures and new or persistent UI over 3 years, with sensitivity analyses for UI subtypes (urge, stress, mixed). RESULTS The prevalence of at least monthly UI was 22% at baseline and urge dominant was the most common UI type (62%). Body mass index (BMI) and total % body fat were associated with higher UI prevalence, whereas lean appendicular body mass, grip strength, and quadriceps torque corrected for BMI were associated with lower UI prevalence, particularly urge incontinence (data not shown). Men in the lowest quintile of BMI and highest quintile of maximum grip strength corrected for BMI were twice as likely to report monthly UI compared to the highest and lowest quintiles, respectively (BMI odds ratio (OR) per kg/m2 = 1.07; 95% confidence interval (CI) 1.04, 1.11; grip strength/BMI OR per kg*m2 = 0.52; 95% CI 0.36, 0.74; Figure 1). Change in body composition or muscle strength was not significantly associated with new or persistent UI. CONCLUSIONS Among older men, lower BMI and body fat and higher lean body mass and muscle strength were associated with lower UI prevalence, but changes in body composition or muscle strength were not significantly associated with change in UI. Our findings suggest that body composition and muscle strength could play a role in male UI risk but changing these factors may not improve UI symptoms. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e39-e40 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Scott R Bauer More articles by this author Anne M Suskind More articles by this author Peggy M Cawthon More articles by this author Steven R Cummings More articles by this author Alison J Huang More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
