Genetic inheritance drives link between parental BMI and childhood body size and eating behaviour, Norwegian cohort study finds
By
Tom A. Bond ,
Summary
This prospective cohort study from the Norwegian Mother, Father and Child Cohort Study (MoBa) investigates whether associations between parental peri-pregnancy BMI and offspring birth weight, childhood BMI up to age 8, and eating behaviour at age 8 are due to genetic inheritance. Using structural equation modelling with data from mothers, fathers, and children, the study finds that parental BMI influences offspring body size and eating behaviour primarily through genetic transmission rather than shared environmental factors. The research highlights the role of genetic inheritance in intergenerational transmission of obesity-related traits.

The study highlights the role of genetic inheritance in intergenerational transmission of obesity-related traits.
Associations between parental peri-pregnancy BMI and offspring birth weight, childhood BMI up to 8 years, and eating behaviour at age 8 were examined using structural equation modelling.
