Association Between Caffeine Intake and Stool Frequency- or Consistency-Defined Constipation: Data From the National Health and Nutrition Examination Survey 2005-2010.

ABSTRACT:

Background/aims

The association between caffeine intake and constipation remains inconclusive. This study aims to investigate whether caffeine intake is associated with constipation.

Methods

This cross-sectional study included 13 941 adults from the 2005-2010 National Health and Nutrition Examination Survey. The weighted logistic regression analyses were exerted to evaluate the association between caffeine intake and constipation. Besides, stratified analyses and interaction tests were conducted to determine the potential modifying factors.

Results

After adjusting for confounders, increased caffeine intake by 100 mg was not associated with constipation, as defined by stool frequency (OR, 1.01; 95% CI, 0.94-1.10) or stool consistency (OR, 1.01; 95% CI, 0.98-1.05). Subg
