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 .
Physical activity to prevent obesity in young children: cluster randomised controlled trial
Objective To assess whether a physical activity intervention reduces body mass index in young children . Design Cluster r and omised controlled single blinded trial over 12 months . Setting Thirty six nurseries in Glasgow , Scotl and . Participants 545 children in their preschool year , mean age 4.2 years ( SD 0.2 ) at baseline . Intervention Enhanced physical activity programme in nursery ( three 30 minute sessions a week over 24 weeks ) plus home based health education aim ed at increasing physical activity through play and reducing sedentary behaviour . Main outcome measure Body mass index , expressed as a st and ard deviation score relative to UK 1990 reference data . Secondary measures were objective ly measured physical activity and sedentary behaviour ; fundamental movement skills ; and evaluation of the process . Results Group allocation had no significant effect on the primary outcome measure at six and 12 months or on measures of physical activity and sedentary behaviour by accelerometry . Children in the intervention group had significantly higher performance in movement skills tests than control children at six month follow-up ( P=0.0027 ; 95 % confidence interval 0.3 to 1.3 ) after adjustment for sex and baseline performance . Conclusions Physical activity can significantly improve motor skills but did not reduce body mass index in young children in this trial . Trial registration Current Controlled Trials IS RCT N36363490
