Clinical and Research Challenges
Background: Lean body mass (LBM) deficits in youth with Inflammatory Bowel Disease (IBD) are well-established and persist despite achievement of remission and restoration of body mass. LBM deficits are associated with both short and long-term health outcomes including sarcopenia, metabolic dysregulation, and development of osteopenia/osteoporosis. LBM deficits are multifactorial though largely explained by inflammatory processes, inadequate dietary intake, and increased energy needs. Physical activity (PA) may also play a role in LBM deficits. Unfortunately, PA and diet in youth with IBD have been understudied. The present cross-sectional study describes relations between PA, diet, body composition, and disease status in a sample of youth with IBD. Methods: 40 patients with IBD aged 8-17 (M=14.58 years; 60% female; 78% Caucasian; 60% Crohn’s) completed the study. Measures included: Moderate to Vigorous PA (MVPA; Godin Leisure Time Exercise Questionnaire), Diet (4-day Food Record), Body Composition and Bone Mineral Density (BMD; Dual-energy X-ray Absorptiometry), and Disease Status (Physician Global Assessment). Analyses included independent samples t-test and two-tailed pearson correlations. Data collection is ongoing. Results: No differences were found on variables based on group. Correlational analyses (N = 40) revealed that greater MVPA was associated with higher LBM (r = .39) and lower fat mass (r = -.38). Average percent protein intake was associated with older age (r = .38), lower percent carbohydrate intake (r = -.72) and higher BMD (r = .37). Less active disease was associated with higher BMI (r = -.38), higher BMD (r = -.46), and higher LBM (r = -.48). Interestingly, disease status was not associated with health behavior engagement. Conclusions: The present study suggests the need for further research into physical activity and diet as a means of improving outcomes for pediatric patients with IBD through improvements in LBM.
