WESTPORT, CT (Reuters Health) – Mechanical factors influence urinary incontinence more than hormonal changes associated with menopause, according to data from a prospective study conducted among Australian women.
The study, reported in Obstetrics and Gynecology for October, involved a cross-sectional survey of 1897 women and a 7-year longitudinal followup of 373 of these subjects. The women ranged in age from 45 to 55 years at baseline and 53 to 64 years at followup. Those in the longitudinal study were premenopausal at baseline and were not using oral contraceptives.
Dr. Janet R. Guthrie and colleagues of the University of Melbourne in Victoria found that, in the baseline cohort, a high body mass index, having had three or more children, and diarrhea or constipation were significantly associated with incontinence on multivariate analysis. Menopausal status was not a significant variable.
During longitudinal followup, the average prevalence of urinary incontinence on a yearly basis was 18%. However, 46% of the cohort was bothered by this condition on at least one occasion.
The researchers observed no association between the development of incontinence and the transition to postmenopause. However, subjects who had undergone hysterectomy were more likely to experience incontinence than their counterparts.
