Role of Sleep Duration and Timing on Paediatric BMI Across Childhood and Adolescence: Do Both Matter?

ABSTRACT:

Background

Adequate sleep duration is a prevention factor for paediatric obesity, but the role of timing is still unclear.

Objectives

To investigate associations of sleep duration and timing with BMI in a large paediatric database.

Methods

Medical chart and survey data were collected from 29 409 children aged 2-18 years who attended well-child visits between Jan 2019 and Dec 2023 (repeated-measures cross-sectional design). Logistic and linear mixed effects regression models accounting for repeated measures estimated odds of overweight/obesity and continuous BMI-for-age CDC-based percentiles for each additional/later hour of sleep duration, midpoint (median of bedtime and wake time), and bedtime, adjusted for potential confounders and stratified by age groups.
