Weight management is an important clinical aspect in the treatment of patients with type 1 diabetes. We evaluated the relationship of eating behaviors (cognitive dietary restraint, disinhibition, and susceptibility to hunger and their subscales) with body composition in adults with type 1 diabetes. Eating behaviors, anthropometry and dietary profile were assessed in 15 overweight adults with type 1 diabetes. Waist circumference was negatively associated with dietary restraint and its subscales (-0.55 < p < -0.49, p=0.06) and positively associated with susceptibility to hunger and its subscales (0.56 < p < 0.74, p<0.05). BMI was also associated with susceptibility to hunger and its subscale (0.52 < p < 0.63, p<0.05). Dietary restraint and its subscale were negatively associated with energy and fat intakes and positively with carbohydrate intake. Susceptibility to hunger was positively associated with energy and fat intakes and tended to be positively associated with total daily insulin dose (p = 0.48, p=0.07) but this tendency was lost when corrected by body weight. When participants were compared by mode of insulin delivery (multiple dose of insulin (MDI or continuous subcutaneous insulin infusion (CSII)), eating behaviors were similar between groups.
