Bioelectrical Impedance Analysis for Body Composition and Nutritional Status in Hospitalized Patients With Inflammatory Bowel Disease / 胃肠病学

ABSTRACT

Background: Inflammatory bowel disease (IBD) affects the digestive tract, and the prevalence of malnutrition is high. Recently, bioelectrical impedance analysis (BIA) has been frequently used clinically for nutritional assessment. Aims: To study the nutritional status of hospitalized IBD patients through BIA combined with serological indicators. Methods: Data from hospitalized IBD patients who underwent BIA test at Renji Hospital, School of Medicine, Shanghai Jiao Tong University between Jan. and Dec. 2015 were collected retrospectively. In the 198 patients enrolled, 129 were Crohn's disease (CD) and 69 were ulcerative colitis (UC). Serological results, as well as BIA results and related indices were compared between CD and UC patients. Results: The serum vitamin B12 level, body weight and body fat mass were significantly lower in patients with CD than in those with UC (P0.05). Differences in BMI and BCMI between active CD and CD in remission were insignificant (P>0.05). Conclusions: Among the hospitalized IBD patients, males with CD have worse nutritional status than males with UC. Except for serum vitamin B12, there is no significant difference in nutritional status between female CD and female UC patients. BIA related indices are effective tool for assessment of nutritional status, which may be used as a complement to BMI.
