A prospective study of loss of control eating for body weight gain in children at high risk for adult obesity

OBJECTIVE: Limited data suggest that disordered-eating may predispose children to excessive weight gain. We investigated the relationship between baseline responses to the Eating Disorder Examination adapted for Children (ChEDE) and change in BMI (kg/m(2)) in children at high risk for adult obesity. METHOD: Children (6-12 years) were administered the ChEDE to assess loss of control (LOC) eating, dietary restraint, and eating, shape, and weight concern. Height and weight were measured at baseline and annually. RESULTS: Between July, 1999, and August, 2007, 772 measurements were obtained from 143 children over 4.5 +/- 1.9 years. LOC eating predicted an increased rate of BMI growth over time (p = .02). Compared with children without LOC, those reporting LOC gained an additional mean 2.4 kg of weight per year. CONCLUSION: LOC is a salient predictor of weight gain during middle childhood. Interventions that decrease LOC eating should be evaluated for their ability to prevent excessive pediatric weight gain.
