Epidemiology, progression, and predictive factors of urinary incontinence in older community‐dwelling Mexican adults: Longitudinal data from the Mexican Health and Aging Study

Abstract

Aims: To understand the epidemiology, progression, and predictive factors of urinary incontinence (UI) in community-dwelling Mexican adults aged ≥ 50 by sex and UI subtypes (stress, urge, and mixed). Methods:We analyzed longitudinal UI data in community-dwelling adults aged ≥ 50 (7783 women and 5843 men) for the 2012 to 2015 period of the Mexican Health and Aging Study. We estimated mixed, stress, and urgency incontinence prevalence (2012); 2-year cumulative incidence and remissions (2015); and progression (2012)(2013)(2014)(2015). A multivariate analysis was undertaken to evaluate the predictive factors for UI and its subtypes by sex. Results: The prevalence of UI was higher (27.7%) for women (average age 65.9 ± 9.5) than 12.5% men (average age 67.4 ± 9.3) and increased with age in both sexes (26.7% in women 50 to 59, to 48.5% in ≥ 90; and 6.8% in men 50 to 59, to 26.2% ≥ 90). The most frequent UI subtypes were mixed in women and urge in men. The cumulative incidence of UI was higher in women (22.9%) than men (12.3%) while its remission was higher in men than women. Predictive factors for UI in both sexes were depressive symptoms, a higher number of concomitant diseases and a history of falls; while advanced age was a factor only for men.Conclusions: UI is a common health problem and its prevalence and severity increase with age. Addressing modifiable risk factors such as depression and falls could decrease the prevalence and incidence of UI and its subtypes.Further studies should also focus on the relationship between mixed UI and male mortality.prevalence, remission 2.3.2 | Covariates Sociodemographic covariates Age by decade group, educational level, marital status, number of children born (only for women), and type of residence (rural or urban).

Quality of life and mortality of Brazilian nonagenarians and centenarians with urinary incontinence

“…Participants that lived alone had a higher frequency of UI, however this data was not statistically significant (58.33%, p=0.820). Although the prevalence was generally higher in women, the percentage of men with UI in our analysis exceeded the reported in other studies 2,8 .…”

Radiotherapy for elder patients aged ≥80 with clinically localized prostate cancer – Brachytherapy enhanced late GU toxicity especially in elderly

“…In general, urinary symptom increased by age. For instance, urinary incontinence is a common health problem, and its prevalence and severity increase with age [21]. Wilson et al reported that patient-reported bladder bother was slightly higher in the group aged !75 years than the group aged <75 years after treatment of conventional and hypofractionated Radiation Therapy [22], which imply the need for meticulous care for elderly patients aged !75 years.…”

Evaluation and treatment of urinary incontinence in the aging male

“…In elderly Brazilian individuals, risk of UI was greater for those who self-reported a 'fair' health status [38]. Another study assessing predictive factors of UI in older communitydwelling Mexican adults identified depressive symptoms, a higher number of concomitant disease, history of falls, and advanced age as being predictive factors [39]. Other risk factors for UI include memory problems, difficulty with talking and walking, mobility limitations, leg edema, and other non-UI urinary problems [40].…”
