title: Urinary frequency in community-dwelling women: what is normal?
abstract: OBJECTIVE
  The objective of the study was to assess urinary frequency in community-dwelling women.
  
  
  METHODS
  Voiding habits were assessed in 4061 women 25-84 years of age using survey responses from the Epidemiology of Prolapse and Incontinence Questionnaire. Bother related to daytime and nighttime frequency was assessed with 100-mm visual analog scales and compared using t tests and analysis of variance.
  
  
  RESULTS
  Median daytime frequency was every 3-4 hours. Urinary frequency every 2 hours or more occurred in 27% and was more bothersome than every 3-4 hours or less (51.7 +/- 30.1 mm vs 23.6 +/- 23.7 mm; P < .001). Nocturia was reported in 72%, whereas 33% had 2 or more voids per night. Bother increased with increasing nighttime frequency (27.3 +/- 26.3 for 1 time vs 57.3 +/- 28.5 for > or = 2 times; P < .001).
  
  
  CONCLUSIONS
  Bothersome urinary frequency is common and occurs when frequency is at least every 2 hours by day and more than once per night.
