The impact of obesity on pediatric Crohn disease (CD) remains poorly characterized. We aimed to evaluate disease-related outcomes in overweight and obese children with CD, compared to normal-weight children. We conducted a retrospective cohort study of children with newly diagnosed CD enrolled in the ImproveCareNow Network. Patients were stratified into normal weight, overweight, and obese groups using standardized weight percentiles. A total of 898 children were included, with 87 children (10%) being overweight and 43 children (5%) being obese; baseline characteristics were similar between groups. There was no significant difference in number of visits in remission during 1 year between normal weight, overweight, and obese children. At 1-year follow-up, nutritional status, growth status, or medication use also did not differ between groups. Hence, obesity does not appear to adversely affect CD outcomes in children with newly diagnosed CD in the first year after diagnosis.
