Sex Differences in the Association between Cortical Thickness and Children's Behavioral Inhibition.

ABSTRACT:

Aim

To investigate sex differences in the association between cortical thickness and behavioral inhibition of 9-10 years old American children.

Materials and methods

This cross-sectional investigation used data from the Adolescent Brain Cognitive Development (ABCD) study. Baseline ABCD data of 10249 American children between ages 9 and 10 were analyzed. The independent variable was cortical thickness measured by structural brain magnetic resonance imaging (sMRI). The primary outcome, behavioral inhibition, was measured based on the behavioral inhibition system (BIS), and behavioral approach system (BAS). Sex was the moderator. Age, race, ethnicity, socioeconomic status indicators, and intracranial volume were covariates.

Results

In the overall sample, high cortical th
