Introduction: Urinary incontinence and sarcopenia are important senior health issues. Nevertheless, there is no available domestic and international data onurinary incontinence and sarcopenia. The aim of this study was to investigate sarcopenia and its association with urinary incontinence in elderly Korean woman.Methods: Korean women (1,313) over 65 years for whom complete data on body composition collected using dual x-ray absorptiometry were analyzed from the Forth Korean National Health and Nutritional Examination Surveys. Class I and II sarcopenia, trunk and total muscle mass were adjusted by Weight and Height. Using of incontinence questionnaire, incontinence is classified by group by diagnosis from doctor and group of symptoms without diagnosis.Results: Adjusting for various confounders, Weight and Height- adjustedsarcopeniaarenoassociationwithurinaryincontinence.((Self-reportedurinaryincontinence:Weight-adjusted sarcopenia (class I OR=1.02, class II OR=0.83, class I P=0.930, class II P=0.545), Height-adjusted sarcopenia(class I OR=0.83, class II OR=0.98, class I P=0.540, class II P=0.987), Diagnosed urinary incontinence: Weight-adjusted sarcopenia (class I OR=0.59, class II OR=1.24, class I P=0.252, class II P=0.647), Height-adjusted sarcopenia(class I OR=0.72, class II OR=3.11, class I P=0.571, class II P=0.326)). Also, Trunk muscle mass adjusting Weight and Height were no correlated with incontinence(Self-reported urinary incontinence: Weight-adjusted(WA) trunk muscle P for trend=0.551, Height-adjusted(HA) trunk muscle P for trend=0.256, Diagnosed urinary incontinence: Weight- adjusted(WA) trunk muscle P for trend=0.556, Height- adjusted(HA) trunk muscle P for trend=0.287)and total trunk muscle mass adjusting Weight and Height were no related with incontinence. (Self-reported urinary incontinence: WA total muscle P for trend = 0.479, HA total muscle P for trend=0.194, Diagnosed urinary incontinence: WA total muscle P for trend = 0.499, HA total muscle P for trend=0.362). Similar trends were observed in total urinary incontinence group.Conclusions: Our study found no relationship between urinary incontinence and sarcopenia in Korean women over 65 years. Also, there are no relationship between the urinary incontinence and trunk muscle mass and lean body mass.
