Prevalence of urinary incontinence and risk factors of stress urinary incontinence in young and middle-aged working women

The prevalence of urinary incontinence and risk factors of stress urinary incontinence were studied in 710 working women between 21 and 59 year old. Six hundred (89%) of them responded to a 10-item questionnaire regarding urinary incontinence (UI). Ul was found in 178 (29.7%). The prevalence was consistent with those in previous reports. Of the 178 UI, 158 (88.7%) were stress urinary incontinence (SUI). Four risk factors, age, childbirth, obesity, and gynecological/urological diseases, were statistically analyzed in 158 women with SUI. Mantel-Haenszel odds ratio (MH-OR) of obesity adjusted for age was 0.97 (95% Confidence interval CI: 0.58-1.60). Furthermore, in the obese group, the incidence of SUI adjusted for childbirth was apparently lower (MH-OR: 0.18, 95%CI: 0.11-0.30, p<0.001). In contrast, in the non-obesity group, the prevalence of SUI rather increased by childbirth (MH-OR: 19.3, 95%CI: 11.4-32.8). It was higher in multipara than in primipara. However, within the grand multipara, the number of childbirth was not associated with increased risk. As opposed to previous reports based on uni-variate analyses, obesity, if adjusted for age, is not directly related to SUI. Furthermore, history of childbirth, which proved to be an apparent risk for SUI in non-obese women, seems to lower such risk in obese women.
