Kim SH, Kim YS, Lee SY, et al. - This study was undertaken to investigate if bioelectrical impedance analysis (BIA) could be used to evaluate the nutritional status of patients with inflammatory bowel disease (IBD). Data from 139 Korean patients with IBD who were treated between November 2018 and November 2019 were retrospectively analyzed. Individuals were classified as having active or inactive IBD based on the Harvey-Bradshaw index (a score of ≥5 indicates active Crohn’s disease) and the partial Mayo scoring index (a score of ≥2 indicates active ulcerative colitis). According to disease activity, BIA results and serum nutritional markers were examined. A total of 47 patients with ulcerative colitis and 92 patients with Crohn’s disease were included in this study. The results showed that the nutritional markers evaluated using BIA were associated with serum nutritional markers and inversely correlated with disease activity. Thus, the outcomes imply that BIA may be a useful tool that can help existing nutritional tests monitor the nutritional status of IBD patients.
