Moderate-to-Vigorous Physical Activity Is Associated With Higher Bone Mineral Density in Children With Inflammatory Bowel Disease

Objectives: Decreased mineral bone density (BMD) and reduced lean body mass (LBM) are common amongst children with inflammatory bowel disease (IBD). The aim of our cross-sectional, observational study was to evaluate the relationship between BMD, body composition and physical activity (PA) in children with IBD in remission. Methods: Total body less head (TLBH) dual energy X-ray absorptiometry (DXA) was used to measure BMD, fat mass (FM) and lean body mass (LBM). Triaxial accelerometer for five consecutive days was used to objectivize PA. Results: Forty pediatric IBD patients in clinical remission (24 boys; age 15.3 ± 0.4 years; Crohn disease [CD], n = 20, ulcerative colitis [UC], n = 18, inflammatory bowel disease-unclassified [IBD-U], n = 2) were recruited. Mean BMD was 0.940 g/cm2 and mean BMD z score was −0.42 ± 0.14. Patients with CD had significantly lower BMD than UC counterparts (P
