Objective: Childhood overweight is related to higher sensitivity for external food cues and less responsiveness towards internal satiety signals. Thus, cognitive psychological models assume an enhanced food attention bias underlying overeating behavior. Nevertheless, this question has only been sparsely investigated so far in younger children and it remains open whether restrained eating behavior plays a correlative role.
Methods: The present study investigated this specific information processing bias for food relevant stimuli in 34 overweight children between 6 and 10 years and 34 normal weight children matched for age, sex and socioeconomic status. Children completed a computerized Food Picture Interference task that assessed reaction time interference effects towards high and low calorie food pictures. Level of hunger and restrained eating were assessed via self-report.
Results: Results indicated that while finding no group difference in general processing speed or hunger level before the task, overweight children showed a higher attentional bias to food pictures than normal weight children. No effect of caloric density was found. However, surprisingly, the interference effect was negatively related to restrained eating in the overweight group only.
Conclusion: The found hypersensitivity for food cues independent of calorie content in overweight children appears to be related to dysfunctional eating, so that future research should consider strategies for attentional retraining.
