Basic Science: Urinary Inconteinence
Moderated Poster Session
Introduction & Objective : A recent study investigated the relationship between dietary nutrients and female urinary incontinence (UI). However, very few data are available on this topic and the results are not consistent across studies. Therefore, we evaluated these relationships using nationally representative data from Korea.
Methods : We included 8,090 women over the age of 20 years who had participated in the Korea National Health and Nutrition Examination Survey IV. We conducted a propensity-matched study by identifying women with UI. Women without UI, matched for age, body mass index, menopause, delivery history, hypertension, diabetes, hypercholesterolemia, stroke, asthma, chronic obstructive pulmonary disease, and amount of total food intake, were included as a control group at a 2:1 ratio (661 women with UI; 1,322 women without UI). Data were analyzed using the chi-square test, Mann-Whitney test, Fisher’s exact test, and logistic regression.
Results : Following propensity score matching, 661 women with UI and 1,322 women without UI were included; the confounders were evenly dispersed and did not differ significantly between the groups.(see FIGURE 1) There was no significant difference in the intake of water, fat, protein, calcium, phosphorus, iron, sodium, potassium, vitamin A, carotene, riboflavin, niacin, and vitamin C. However, carbohydrate intake was significantly higher in the UI group than in the control group (median [interquartile range]: 282.3 g/day [214.7; 352.0] vs. 267.7 g/day [212.6; 339.1]; P=0.041). (see FIGURE 2)
Conclusions : High carbohydrate intake was the significant and independent risk factor in this propensity score-matched analysis.
