Aim To assess different techniques to measure body composition in paediatric patients with inflammatory bowel disease using dual energy X‐ray absorptiometry as a reference method. We hypothesised that a three‐compartment model may demonstrate superiority over other methods as skinfold thickness equations and bioelectrical impedance analysis. Methods Body composition was assessed using skinfold thickness equations, bioelectrical impedance analysis and the three‐compartment model. Data obtained with these methods were compared to the results obtained by dual energy X‐ray absorptiometry. Statistical analysis was performed using Spearman's correlation and Bland–Altman's limits of agreement method. Results Twenty‐one paediatric patients with inflammatory bowel disease were included: 11 females and 10 males; mean age for the entire group: 14.3 years, range 12–16 years. In children with inflammatory bowel disease, skinfold thickness equations, bioelectrical impedance analysis and the three‐compartment model showed reliable measurements with small differences in the percentage of total body fat and good limits of agreements. Conclusion The assessment of body composition using bioelectrical impedance analysis provides a valid and accurate method in children with inflammatory bowel disease as compared to dual energy X‐ray absorptiometry. In the future, superiority of 3‐compartment model in research and clinical settings of nutritional intervention and disease status in children with inflammatory bowel disease remains to be demonstrated.
