BIA was performed for patients with UC and CD, and body composition parameters, including protein, fat, skeletal muscle mass, segmental muscle and water, body cell mass, waistline circumference, visceral fat area, basal metabolic rate, and bilateral upper arm girth and skinfold thickness, were recorded. *, P<0.05 was considered statistically significant. UC, ulcerative colitis; CD, Crohn’s disease; BIA, bioelectrical impendence analysis.
