Overall , we found data that support a negative relationship between obesity and various aspects of neurocognitive functioning , such as executive functioning , attention , visuo-spatial performance , and motor skill .
The existing literature is mixed on the effects among obesity , general cognitive functioning , language , learning , memory , and academic achievement .
Executive dysfunction is associated with obesity-related behaviors , such as increased intake , disinhibited eating , and less physical activity .
Physical activity is positively linked with motor skill .
Childhood obesity rates have risen dramatically over the past few decades .
Although obesity has been linked to poorer neurocognitive functioning in adults , much less is known about this relationship in children and adolescents .
Therefore , we conducted a systematic review to examine the relationship between obesity and obesity-related behaviors with neurocognitive functioning in youth .
Fitness, fatness, cognition, behavior, and academic achievement among overweight children: do cross-sectional associations correspond to exercise trial outcomes?
BACKGROUND This study examined associations of fitness and fatness with cognitive processes , academic achievement , and behavior , independent of demographic factors , at the baseline of an exercise trial . METHODS Overweight , sedentary but otherwise healthy 7 - 11 year olds ( N=170 ) participated in a study of health , cognition and achievement in the Augusta , GA area from 2003 - 2006 . Children underwent evaluations of fatness and fitness , psychological assessment s of cognition and academic achievement , and behavior ratings by parents and teachers . Partial correlations examined associations of fitness and fatness with cognitive and achievement scores and behavior ratings , controlling for demographic factors . RESULTS Fitness was associated with better cognition , achievement and behavior , and fatness with worse scores . Specifically , executive function , mathematics and reading achievement , and parent ratings of child behavior were related to fitness and fatness . Teacher ratings were related to fitness . CONCLUSION These results extend prior studies by providing reliable , st and ardized measures of cognitive processes , achievement , and behavior in relation to detailed measures of fitness and fatness . However , cross-sectional associations do not necessarily indicate that improving one factor , such as fatness or fitness , will result in improvements in factors that were associated with it . Thus , r and omized clinical trials are necessary to determine the effects of interventions
