Longitudinal assessment of brain structure and behaviour in youth with rapid weight gain: Potential contributing causes and consequences

Pediatr ObesPublished Longitudinal cohort study

Authors' conclusion

These findings suggest that brain structure in pre-adolescence may predispose some to rapid weight gain and that weight gain itself may alter maturational brain change in regions important for food intake and impulsivity. Behavioural interventions that target inhibitory control may improve trajectories of brain maturation and facilitate healthier behaviours.

Study context

Main finding

As reported in the abstract

Rapid weight gain associated with structural variation in brain features in regions of executive functioning, appetitive control and reward sensitivity

39 brain features

Observational data: associations, not effects.

Further findings

Brain structure change and impulsivity · Two years later

WG youth showed differences in change over time in several of these regions
WG youth performed worse on measures of impulsivity
