Body Mass Index at Presentation of Inflammatory Bowel Disease in Children.

Our data is consistent with other series. Showing most children had a normal BMI, regardless of disease severity or phenotypes. One confounding factor is the possibility of delay in referral to GI. This could mean some obese children may fall in the normal BMI range at the time of diagnosis due to ongoing weight loss. Future studies should include prospective cohort studies, comparing incidence of IBD in obese and non-obese patients, severity at presentation, duration of symptoms, and clinical outcomes.
