A. Statement of Objective: To conduct a randomized trial to evaluate the impact of caffeine restriction on Overactive Bladder(OAB) symptoms including urinary frequency, nocturia, incontinence episodes, symptom severity and bother and quality of life.

B. Specific Aims/Hypothesis:

  1. To determine if reduction in caffeine intake decreases urinary frequency, nocturia and incontinence episodes as measured on a 3-day voiding diary in women with Overactive Bladder (OAB).

    We hypothesize that women with overactive bladder will report less frequent urination and decreased nocturia and incontinence episodes with caffeine reduction.

  2. To determine whether caffeine reduction results in decreased symptom severity and bother and improved quality of life scores as measured by the Questionnaire for Incontinence Severity Index (ISI), Questionnaire for Urinary Incontinence Diagnosis (QUID), Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7).

We hypothesize that women with OAB who reduce their intake of caffeine will report decreased symptom bother and improved quality of life as measured by the ISI, UDI-6 and the IIQ-
