Objectives To evaluate the relationship between dietary nutrients and female urinary incontinence using nationally representative data from Korea. Methods We included 8090 women aged >20 years who had participated in the Korea National Health and Nutrition Examination Survey IV . We carried out a propensity‐matched study by identifying women with urinary incontinence . Women without urinary incontinence , 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 urinary incontinence ; 1322 women without urinary incontinence ). Data were analyzed using the χ 2 ‐test, Mann–Whitney test, Fisher's exact test and logistic regression. Results Following propensity score matching, 661 women with urinary incontinence and 1322 women without urinary incontinence were included; the confounders were evenly dispersed and did not differ significantly between the groups. 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 urinary incontinence 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). Conclusion High carbohydrate intake seems to be significantly related to female urinary incontinence in the Korean population.
