Abstract
INTRODUCTION AND HYPOTHESIS: Overactive bladder (OAB) and urinary incontinence (UI) are prevalent in older women. We investigated relations of toileting behaviors and urinary urge cues to OAB and UI in women ≥ 65 years. We tested mediation hypotheses that toileting behaviors lead to higher sensitivity to urinary urge cues (the mediator), which leads to both OAB and UI. METHODS: An e-panel was recruited to respond to an electronic survey that included demographic information, Urinary Cues Scale version 2, Toileting Behaviors-Women's Elimination Behaviors (TB-WEB) scale, and the International Consultation on Incontinence Questionnaire Short Forms for Urinary Incontinence (ICIQ-SF-UI) and Overactive Bladder (ICIQ-SF-OAB). Descriptive statistics were conducted; correlation matrices were created to explore relationships among major variables. Regression analyses were conducted to test our mediation hypotheses. RESULTS: There were 338 respondents with average age 70.9 (SD + 5.55) years. Most were white, overweight or obese, and had UI. Urinary urge cues fully mediated the relationship of TB-WEB with OAB. Urinary urge cues partially mediated the relationship of TB-WEB with UI; the direct effect of toileting behaviors on UI remained significant. Age and body mass index had significant partial correlations with UI but not with OAB. DISCUSSION: Toileting behaviors appear to contribute to sensitivity to urinary cues, which are related to both OAB and UI. Toileting behaviors have indirect effects on OAB and both indirect and direct effects on UI. Interventions to change toileting behaviors and extinguish urinary cues are needed. CONCLUSIONS: Behavioral and conditioning factors contribute to UI in older women.
