Associations Between U.S. Women’s Toileting Behaviors and Lower Urinary Tract Symptoms: A Cross-Sectional Analysis of RISE for HEALTH Study Data

Introduction: Toileting behaviors are recognized as potential contributors to lower urinary tract symptoms (LUTS) in women. This study examines the association between toileting behaviors and LUTS among community-dwelling women and whether age modifies these associations. Methods: Cross-sectional analyses were conducted using baseline data from a population-based cohort study, RISE FOR HEALTH (RISE). Women completed validated questionnaires assessing toileting behaviors (Toileting Behaviors-Women's Elimination Behaviors scale) and LUTS (10-item Lower Urinary Tract Dysfunction Research Network-Symptom Index [LURN SI-10]). Toileting behaviors included place preference for voiding, premature voiding, delayed voiding, straining to void, and toileting position. LUTS items included urine storage, emptying, and postmicturition symptoms. Associations were analyzed by proportional odds logistic regression. Analyses were stratified by seven age groupings. Results: Data from 2,327 women (mean age 51.1 years, standard deviation = 18.2) were analyzed. Delayed voiding was most strongly associated with the LURN SI-10 composite score (odds ratio [OR] 1.89; 95% confidence interval [CI]: 1.72, 2.09) and urgency incontinence (OR 1.87; 95% CI: 1.66, 2.10). Premature voiding showed the strongest association with urgency (OR 1.82; 95% CI: 1.68, 2.04). Straining was strongly associated with emptying symptoms, including delay before urine starts (OR 2.28; 95% CI: 2.05, 2.54) and slow stream (OR 2.28; 95% CI: 2.05, 2.53). Age modified associations between delayed voiding and LUTS, with strongest associations among 18- to 25 year-old women. Conclusions: Premature voiding, delayed voiding, and straining showed the strongest associations with LUTS in this cross-sectional analysis. Longitudinal studies are needed to clarify the directionality of these associations. Educating young women on healthy toileting habits may mitigate potential effects of unhealthy toileting behaviors on bladder health.
