Fatigue in children and adolescents with inflammatory bowel disease.

Aim: To identify factors other than active disease and anemia that contribute to fatigue in pediatric inflammatory bowel disease (IBD).

Methods: We performed an electronic search in Medline and EMBASE from their inception to May 2017 using the search term "fatigue" or the related keywords "physical impairment" and "inflammatory bowel disease" with the filter "child" (age 0-18 years). Cross-sectional and case-control studies were included.
