Association of Sedentary Behavior with Brain Structure and Intelligence in Children with Overweight or Obesity: The ActiveBrains Project.

ABSTRACT: We investigated the associations of different sedentary behaviors (SB) with gray matter volume and we tested whether SB related to gray matter volume is associated with intelligence.

Methods

99 children with overweight or obesity aged 8-11 years participated in this cross-sectional study. SB was measured using the Youth Activity Profile-Spain questionnaire. T1-weighted images were acquired with a 3.0 T Magnetom Tim Trio system. Intelligence was assessed with the Kaufman Brief Test. Whole-brain voxel-wise multiple regression models were used to test the associations of each SB with gray matter volume.

Results

Watching TV was associated with lower gray matter volume in six brain regions (β ranging -0.314 to -0.489 and cluster size 106 to 323 voxels; p < 0.001), playing v
