Background: Gastrointestinal (GI) symptoms are believed to be common in the general population, and constipation is one of the most representative GI symptoms. However, the prevalence and risk factors of functional constipation are not well known in Korea. We aimed to study the prevalence of, and risk factors for, constipation in the elderly. Methods: We randomly selected 852 among 854 (excluded by cancer and dementia) subjects, ages 65 yr and older, in three different geriatric welfare facilities in December, 2003. The prevalence of functional constipation was based on the Rome II criteria and the survey on risk factors for constipation was performed. Results: Functional constipation had a prevalence of 26.6% and there was no difference between men and women. Exercise, fluid center dot fruit center dot vegetable intake, anal diseases and age related risk factors were associated with constipation. Conclusion: In the elderly, constipation is a common complaint. Further studies are now required for risk factors of constipation.
