Subjective urinary urgency in middle age women: A population-based study

There are few population-based studies evaluating the epidemiology of overactive bladder syndrome (OAB) in women, especially in the climacteric stage where there is a decrease in estrogen production. This study aimed to assess the prevalence of OAB and associated factors in climacteric Brazilian women.

A descriptive, exploratory, cross-sectional study was conducted between September 2012 and June 2013 with 749 women (a population-based household survey). The dependent variable was OAB, defined as the presence of urinary urgency, with or without urinary incontinence, and when there was no concomitant stress urinary incontinence. The independent variables were sociodemographic data, health related habits and problems, self-perception of health, and gynecological background. Statistical analysis was carried out by Chi-square test and Poisson regression using the backward selection criteria.

Mean age was 52.5 (± 4.4) years. With regard to menopausal status, 16% were premenopausal, 16% perimenopausal and 68% postmenopausal. The prevalence of OAB was 7.8%. The vast majority of women had only urinary urgency. Only two women who responded to the interview reported urge incontinence. In the final statistical model, vaginal dryness (PR 1.75; 95% CI 1.13-2.69; p=0.012) and bilateral oophorectomy (PR 2.21; 95% CI 1.11-4.40; p=0.025) were associated with a greater prevalence of OAB.

Health professionals should adopt a proactive behavior in surgically menopausal women and those with a history of genital atrophy to identify and treat OAB, thus contributing to an improved quality of life and healthier aging.
