Multilevel factors associated with sleep duration and bedtime regularity in U.S. children with and without neurodevelopmental disorders: a nationally representative study.

ABSTRACT:

Background

This study compared multilevel factors associated with sleep duration and bedtime regularity in children with and without neurological and developmental disorders (NDD) using a nationally representative sample.

Methods

We combined data from the 2016-2017, 2018-2019, and 2020-2021 United States National Survey of Children's Health (NSCH), including 86,014 children aged 9-17 years.
