P115 RELATIONS BETWEEN DISEASE STATUS AND BODY COMPOSITION IN PEDIATRIC INFLAMMATORY BOWEL DISEASE

Abstract

Abstract Objective To evaluate the effect of remission status on physical activity, and body composition in pediatric patients with inflammatory bowel disease (PIBD) and healthy peers. Methods Single center cohort study including 54 PIBD patients and 33 healthy peers. During initial study visit, a brief demographic questionnaire, physical activity questionnaire completed by participants and instructions on recording dietary intake were given. Physicians completed the Physician Global Assessment (PGA) for disease severity. Medical chart abstraction done to obtain disease variables of interest. DEXA scan completed one week later to obtain information on body composition. Variables of interest were compared between the three groups (IBD-Remission, IBD-Active and healthy controls) using an ANOVA or Chi square test as appropriate. Results IBD patients were older than controls, reported lower quality of life (73.9 vs 80.9) and engaged in less MVPA (195.4 versus 361.1). IBD-Active group had a significantly lower lean body mass, bone mineral density and time spent in MVPA compared to IBD-Remission group and healthy controls. IBD-Remission group had a significantly lower percentage of biologic use (55% vs 87%) and comorbidities (26% vs 44%) compared to IBD-active group. IBD-remission group also had a lower fat mass percentage. Discussion In this study, we report significantly favorable LBM, BMD, and time spent in MVPA in patients with IBD in remission compared to those not in remission with the former demonstrating a body composition resembling to that of healthy peers. While an improvement in BMD was observed with remission, the scores were still lower than controls.
