Correlates of constipation in an ambulatory elderly population

Abstract

Constipation is a common and often perplexing problem for elderly people. The prevalence of self-reported constipation and factors associated with constipation were investigated in 3,166 people over age 65. Twenty-six percent of women and 15.8% of men reported recurrent constipation (p less than 0.0001). There was a significant increase in reported constipation with increasing age (p less than 0.0001). Multiple factors were found to correlate with self-reported constipation. A logistic regression model revealed 13 factors of significance in predicting constipation. The most important factors were age, sex, total number of drugs taken, pain in the abdomen, and hemorrhoids (p less than 0.0001). Specific drugs do not appear to be important factors in constipation in the elderly. Elderly people who report the use of multiple drugs, pain in the abdomen, and hemorrhoids are at increased risk for constipation.
