The role of genetic and environmental influences on the association between childhood ADHD symptoms and BMI.

ABSTRACT:

Background/objectives

Although childhood attention deficit hyperactivity disorder (ADHD) has been previously associated with concurrent and later obesity in adulthood, the etiology of this association remains unclear. The objective of this study is to determine the shared genetic effects of ADHD symptoms and BMI in a large sample of sibling pairs, consider how these shared effects may vary over time, and examine potential sex differences.

Subject/methods

Cholesky decomposition models were
