For a study, researchers conducted an observational study to determine the connection between mineral bone density (BMD), body composition, and physical activity (PA) in children with inflammatory bowel disease (IBD) who were in remission. BMD, fat mass (FM), and lean body mass (LBM) were measured using total body less head (TLBH) dual-energy X-ray absorptiometry (DXA). PA was measured using a triaxial accelerometer for 5 days in a row. About 24 paediatric IBD patients in clinical remission (24 boys; age 15.3± 0.4 years; Crohn’s disease [CD], n=20, ulcerative colitis [UC], n=18, and inflammatory bowel disease-unclassified [IBD-U], n=2) were recruited. BMD was 0.940 g/cm2 on average, with a z score of somewhere between −0.42 and 0.14. BMD was substantially lower in CD patients than in UC patients (P<0.001). The average amount of time spent in physical activity each day was somewhere between 247.24 and 16.71 minutes, with somewhere between 45.73 and 8.22 minutes spent in moderate-to-vigorous activity (MVPA). The time spent in MVPA was found to have a significant positive connection with the BMD z score (P=0.003) and LBM z score (P=0.026). The favorable connection between MVPA and BMD z score was verified by multivariate analysis. The amount of protein consumed daily has no bearing on BMD. LBM z score was inversely linked with cumulative glucocorticoid dose (P=0.003) but not with BMD z score (P=0.069). There was a strong positive association between MVPA, LBM, and BMD, according to the study. Longitudinal studies were needed to understand the changeable factors determining body health and composition.
