Differences in eating styles between overweight and normal-weight youngsters were investigated with a child version of the Dutch Eating Behavior Questionnaire (DEBQ). Subjects were children (n=1458; M: 10.1; SD=1.3) and adolescents (n=1016; M: 14.9; SD=1.5). Overweight adolescent girls scored high on emotional eating while overweight adolescent boys displayed more external eating. In overweight children, already 10.5 per cent displayed emotional eating and 38.4 per cent reported external eating. All overweight youngsters reported restrained attitudes. Eating styles were positively associated with indicators of eating pathology. The results suggest the use of appropriate norms that take into account the child's age, gender and overweight status.
A subgroup of overweight children appears to have a stronger tendency to act on impulse than normal weight children, and demonstrated an impulsivity prone personality. Hence, overweight children should be screened for impulse control deficiencies. More research is needed to clear out the robustness of gender differences, the existence of a specific personality profile and possibly common underlying mechanisms of childhood obesity and Attention Deficit Hyperactivity Disorder.
The study investigated whether obese children are more impulsive than lean children, taking into account the multidimensionality of the construct. Responses of 41 overweight children were compared to those of 40 lean children. The Stop Task, Circle Drawing Task and Opposite Worlds Task were administered to measure executive inhibitory control, and the Maudsley Index of Childhood Delay Aversion and the Door Opening Task were administered to measure motivational inhibitory control. On the Stop Task, the overweight children showed less inhibitory control. On the Opposite Worlds task, we found no significant difference, whereas on the Circle Drawing Task an unexpected group difference was found. Although on the Door Opening Task the overweight children showed greater reward sensitivity, they were equally motivated to wait on the Maudsley Index of Childhood Delay. We conclude that the findings were different depending on the measure used, but that they suggest that overweight children can be characterised by a decrease in executive and motivational inhibitory control.
A developmental pathway from weight problems through dieting to binge eating is plausible for a subgroup of obese children. Convergence between parent and child reports supports the assumption that children's reports are a viable means of monitoring dieting and weight behaviors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
