The onset of pubertal development and actigraphy-assessed sleep during middle childhood: Racial, gender, and genetic effects.

ABSTRACT:

Objective

This study (1) examined pubertal development in relation to actigraphy-assessed sleep in twin children, and tested whether associations differed by child race and gender, (2) modeled genetic and environmental influences on pubertal development and sleep indicators, and (3) examined genetic and environmental influences on the covariation of puberty and sleep.

Design

The classic twin design was used to examine genetic and environmental contributions to puberty and sleep and their associations.

Setting

Data were collected from community-dwelling urban and rural families of twins in the southwestern U.S.

Participants

The racially and socioeconomically diverse sample included 596 twin children (M_age = 8.41, SD = 0.69; 51.7% female; 66.3% white;
