Biochemical Measures of Diabetes are Not Independent Predictors of Urinary Incontinence in Women

Purpose: Diabetes mellitus type II is considered an important risk factor for urinary incontinence. We investigated associations among biochemical measures of diabetes with stress and urgency urinary incontinence in a nationally representative sample of American women.Materials and Methods: We performed a cross-sectional analysis of female adult participants in the 2001 to 2010 NHANES (National Health and Nutrition Examination Survey). Urinary incontinence was ascertained by self-report. Diabetes was defined by calculated measures of glycemic control and insulin resistance. Glycemic control was classified by HbA1c and fasting plasma glucose. Insulin resistance was estimated by fasting plasma insulin and the homeostasis model assessment of insulin resistance definition. Logistic regression models adjusted for sociodemographic variables and risk factors were fitted for each measure of diabetes mellitus type II severity, and stress and urgency urinary incontinence. Stepwise multivariable logistic regression ...
