AIMS:To compare the descriptive epidemiology of overactive bladder (OAB) of presumed neurologic origin (NOAB) to OAB of non-neurologic origin (N-NOAB).
METHODS: Five thousand five hundred three community-dwelling persons aged 30-79 were interviewed regarding urologic symptoms (2002-2005). NOAB was defined as symptoms of urgency and/or urgency incontinence among those with a self-reported history of healthcare provider diagnosed stroke (N = 98), multiple sclerosis (N = 21), or Parkinson's disease (N = 7). N-NOAB was defined identically but occurring among those not reporting neurologic disease (ND). Prevalence estimates were weighted to reflect sampling design; chi-square, Fisher's exact, or t-tests were used to test differences. Urologic symptom interference was assessed using the Epstein scale, while the impact of urinary incontinence (UI) on health-related quality-of-life (HRQOL) was measured using a modification of the Incontinence Impact Questionnaire-7.
RESULTS: Forty-five (31.0%) of 125 persons with ND and 994 (16.7%) of 5378 persons without ND reported OAB symptoms. The overall prevalence of NOAB and N-NOAB was 0.6% and 16.4%, respectively. Persons with NOAB had higher (worse) mean American Urologic Association Symptom Index scores (13.0 vs. 10.0, P = 0.09) compared to those with N-NOAB, and were significantly more likely to have diabetes, high blood pressure, cardiac disease, and fair/poor self-reported health (all P < 0.05). Mean symptom interference and UI HRQOL scores were significantly higher (worse) in the NOAB group compared to persons with N-NOAB (all P < 0.05).
CONCLUSIONS: Persons with NOAB appeared to have a greater burden of urologic illness with respect to symptom interference and HRQOL compared to persons with N-NOAB.
