title: Association between Muscle Loss and Urinary Incontinence in Elderly Korean Women.
abstract: BACKGROUND
  Incontinence and muscle loss are important senior health issues. Nevertheless, there are no available domestic or international studies on the association between urinary incontinence and muscle loss. The aim of this study was to investigate the association between muscle loss and urinary incontinence in elderly Korean woman.
  
  
  METHODS
  Korean women (1,313) ≥65 years of age whose complete body composition data were collected using dual X-ray absorptiometry were analyzed from the Fourth Korean National Health and Nutritional Examination Surveys. Class I and II losses of the appendicular, truncal, and total muscle mass were defined using adjustments for weight and height. Each participant's incontinence status was collected using constructed questionnaires. Multiple logistic regression was performed to examine the association between muscle loss and incontinence.
  
  
  RESULTS
  On the basis of physician-diagnosed incontinence, weight- and height-adjusted muscle loss showed no association with urinary incontinence (weight-adjusted muscle loss: class I adjusted odds ratio [aOR], 0.77; 95% confidence interval [CI], 0.34 to 1.73; class II aOR, 1.37; 95% CI, 0.59 to 3.18; height-adjusted muscle loss: class I aOR, 0.51; 95% CI, 0.18 to 1.51; class II aOR, 1.86; 95% CI, 0.22 to 15.79). Similar results were observed for truncal muscle and total muscle mass as well as self-reported urinary incontinence.
  
  
  CONCLUSIONS
  Our study found no association between urinary incontinence and appendicular, truncal, and total muscle loss in elderly Korean women.
