International audience ; Background: Previous studies link obesity to neurophysiological changes, however cognitive outcomes in adolescents who are overweight or obese, especially with their eatin g behavior, require further documentation. Objective: To examine the association between body mass index (BMI), eating behavior, and cognitive performance in Mexican adolescents. Method: Urban Mexican adolescents completed CANTAB tasks assessing spatial memory (PAL: Paired Associates Learning; SSP: Spatial Span), verbal memory (VRM: Verbal Recognition Memory), and emotional recognition (ERT: Emotion Recognition Task), as well as eating behavior measures. Cognitive performance was compared between normal-weight and overweight and obesity groups. Hierarchical regressions tested BMI and eating disor der symptoms as predictors of cognition. Results: The overweight and obesity group showed significantly poorer performance on PAL and SSP. Multivariate analyses revealed BMI, sex, and age predicted PAL, SSP, and VRM performance. Eating behavior differed by weight group, but only eating disorder symptoms predicted cognition. Neither BMI nor eatin g behavior predicted ERT performance. Conclusions: Spatial working memory is weaker in adolescents who are overweight or obese. Higher BMI also relates to poorer verbal memory, expanding known executive function deficits. Overall, these data reinforce the evidence on the negative effects of hyperadiposity on c ognitive performance in adolescents . |
