Association of pharmacologic treatment of urgency urinary incontinence with sleep quality and daytime sleepiness

Abstract

OBJECTIVE: To evaluate the association between pharmacologic therapy for urgency urinary incontinence (UUI) and sleep quality. METHODS: We conducted a planned secondary data analysis of sleep outcomes in a previously conducted multicenter, double-blind, 12-week randomized trial of pharmacologic therapy for urgency-predominant incontinence among community-dwelling women self-diagnosed using the 3-Incontinence Questions questionnaire. Participants (N=645) were assigned randomly to 4-8 mg antimuscarinic therapy daily or placebo. At baseline and 12 weeks, participants completed a validated voiding diary to evaluate incontinence and voiding symptoms, the Pittsburgh Sleep Quality Index to evaluate sleep quality, and the Epworth Sleepiness Scale to evaluate daytime sleepiness. RESULTS: Mean (SD) age was 56 (±14) years, 68% were white, and 57% had poor sleep quality (Pittsburgh Sleep Quality Index score greater than 5). Mean frequency of any urinary incontinence and UUI was 4.6 and 3.9 episodes/d, respectively. After 12 weeks, women randomized to the antimuscarinic group reported greater decrease compared with the placebo group in UUI frequency (0.9 episodes/d; P
