Urinary incontinence and its association with socioeconomic status among middle-aged and older persons in Taiwan: A population-based study

Abstract

Aim: This study aimed to explore the association between socioeconomic status and urinary incontinence (UI).

Methods: We used data from the three waves of the Taiwan Longitudinal Study on Aging. This study included 2458 women and 2866 men aged ≥50 years. We used logistic random effects models to examine the associations of interest, adjusting for demographics, health-related behaviors, disability, number of health conditions and prostate problems for men and numbers of children for women.

Results: In adjusted analysis, women with secondary education least frequently reported UI compared with women with no formal education (adjusted odds ratio [AOR] 0.41, 95% confidence interval [95% CI] 0.22-0.79). Those with severe economic hardships (vs those with no economic hardships) had an increased risk of UI among men and women (AOR 2.71, 95% CI 1.72-4.25 and AOR 1.94, 95% CI 1.31-2.88, respectively). Compared with men doing mentally demanding jobs, service workers/salesperson and retired men were more prone to UI (AOR 2.67, 95% CI 1.14-6.36 and AOR 2.41, 95% CI 1.19-4.87, respectively). Further analysis showed that the associations of economic hardship with UI were attenuated when adjusting for access to healthcare.

Conclusion: No formal education in women and severe economic hardship in both the sexes were associated with an increased risk of UI among middle-aged and older persons. The disparities should be taken into account in interventions for prevention, treatment and management of UI. Geriatr Gerontol Int 2021; 21: 245-253.
