Obesity

FTO variation and early frontostriatal brain development in children

Obesity (Silver Spring)Published Longitudinal cohort study

Authors' conclusion

These findings suggest that common genetic risk for obesity is associated with differences in early development of brain reward circuitry and argue for investigating dynamic relationships among genotype, brain, behavior, and weight throughout development.

Study context

Population
Children in RESONANCE, a longitudinal study of early brain development (102 female, 126 male)
Participants
228 children
Exposure
FTO rs9939609 risk allele carriers vs no risk allele
Outcome
Growth trajectories of nucleus accumbens and frontal lobe volumes, total gray matter and white matter volume
Follow-up
Infancy through middle childhood
Methodological detailsfunctional concurrent regression models, MRI from infancy through middle childhood
  • Functional concurrent regression models
  • MRI from infancy through middle childhood

Main finding

As reported in the abstract

Nucleus accumbens volume (adjusted for total brain volume) · 750 to 2250 days (2-6 years)
  • Greater nucleus accumbens volume in AA vs TT in the interval of 750 to 2250 days (2-6 years)
  • Bootstrap pointwise 95% CI for regression coefficient functions
  • Adjusted for sex, BMI z score and maternal education

Observational data: associations, not effects.
