Greater Physical Activity May Increase Incontinence in Women
Slightly increased odds of moderate/severe SUI with substantially increased lifetime physical activity.
(HealthDay News) -- For middle-aged women, substantially increased overall lifetime physical activity is associated with slightly increased odds of moderate/severe stress urinary incontinence (SUI), and greater strenuous activity during the teen years may modestly increase SUI risk. The findings were published in the American Journal of Obstetrics & Gynecology.
Ingrid E. Nygaard, M.D., from the University of Utah School of Medicine in Salt Lake City, and colleagues examined whether moderate/severe SUI correlated with overall lifetime physical and leisure activity in middle-aged women. Data were included for 1,538 women aged 39 to 65 years who underwent Pelvic Organ Prolapse Quantification examination. 213 cases were identified and matched to controls in a 1:1 ratio by age group.
The researchers observed a slight increase in the odds of SUI with overall lifetime activity (odds ratio [OR], 1.20 per 70 additional metabolic equivalent task-hours/week; 95% confidence interval [CI], 1.02 to 1.41). There was no association for SUI with lifetime strenuous activity (OR, 1.11; 95% CI, 0.99 to 1.25). The odds of SUI were increased modestly with greater strenuous activity in teen years (OR, 1.37 per 7 additional hours/week; 95% CI, 1.09 to 1.71). There was a linear increase in the predicted probability of SUI in women exceeding 7.5 hours of strenuous activity/week during teen years.
"In middle-aged women, a slight increased odds of SUI was noted only after substantially increased overall lifetime physical activity," the authors write. "Greater strenuous activity during teen years modestly increased SUI odds."
