title: Prevalence of urinary frequency in Taiwanese women aged 20-59 years.
abstract: OBJECTIVE
  To evaluate the prevalence of daytime urinary frequency among Taiwanese women aged 20-59 years.
  
  
  METHODS
  In 1998, there were an estimated 5.9 million female residents aged 20-59 years in Taiwan. A random sample of 4,549 women was chosen by multistage sampling. Face-to-face visits with 3,537 women were completed by trained professional interviewers within 3 months of the subjects' selection. Questions about lower urinary tract symptoms, sociodemographics, reproduction, and medical and surgical histories were recorded. The factors were assessed by frequency and logistic regression analyses using a significance level of less than 0.05.
  
  
  RESULTS
  The prevalence of urinary frequency in Taiwanese women aged 20-59 years was 5.2% (182/3,519); 18 interviewees did not answer the question about frequency and were excluded. For those who complained of frequency, 47.2% voided 8-15 times a day, 37.4% voided 16-23 times a day, 1.1% voided 24-31 times a day and 14.3% voided more than 31 times a day. The prevalence of urinary frequency was not linked to age (p = 0.326).
  
  
  CONCLUSIONS
  Urinary frequency is a common symptom in women of all ages and is not significantly related to age. More than half of the women interviewed admitted that less than an hour occurred between visits to the restroom during the daytime.
