| Research Abstract |
Recent studies have indicated that higher BMI during childhood is associated with lower academic achievement scores, suggesting that maintaining a healthy weight may be essential for cognitive development. However, evidence regarding the association between childhood obesity and cognitive health has remained scarce. Accordingly, this study examined whether childhood obesity is associated with cognitive control, which has been heavily implicated in academic achievement. Preadolescent participants (n = 45; mean age = 10.5 years) performed a modified flanker task while their assessing their task performance and the N2 and P3 components of the event-related brain potential. Results indicated that higher BMI was associated with longer reaction time, larger N2 amplitude, and longer P3 latency for a task condition requiring greater amounts of cognitive control. These findings suggest that childhood obesity is negatively associated with cognitive control.
