56 THE PREVALENCE OF OVERACTIVE BLADDER (OAB) BY RACE: RESULTS FROM THE OAB-POLL STUDY

Abstract

INTRODUCTION AND OBJECTIVES: Little is known as to the prevalence of OAB by race. OAB-POLL estimated the prevalence of OAB in a large population-based study in the US by oversampling minorities to evaluate impacts stratified by race. METHODS: This cross-sectional, population-representative survey was conducted via the Internet in the US among men and women age 18-70. The LUTS tool, which uses ICS definitions and was developed based on extensive qualitative research, was used to assess how often participants experienced urinary symptoms during the past 4 weeks on a 5-point Likert scale. OAB was defined by the presence of urinary urgency “sometimes” or “often” and/or the presence of urgency urinary incontinence (UUI). Descriptive statistics were used to evaluate group differences by race and age. RESULTS: Overall response rate was 56.7%; 10,000 men and women participated (blacks, 2,000; Hispanics, 2,000; whites, 6,000). Mean age was 41.3 for men and 42.2 for women. Rates of OAB “sometimes” and “often” were 17% and 8% in men and 30% and 20% in women ages 18–70 (Table). Regardless of the threshold used, OAB prevalence was significantly higher for black men compared to Hispanic and white men, but race was not statistically significant among women except for all ages 18–70 “often”. Statistically significant increases in prevalence were found with each decade increase in advancing age for both thresholds in men and women. CONCLUSIONS: Consistent with prior research, OAB is highly prevalent in both men and women and increases with advancing age. OAB has a similar high prevalence in blacks, Hispanics and whites. However, results suggest a higher prevalence in black males. Source of Funding: Pfizer Inc.
