Adverse Childhood Experiences and Accelerometer-Measured Physical Activity and Sleep in Preadolescents

Abstract

ObjectiveTo assess the relationship between adverse childhood experiences (ACEs) and objective measures of physical activity and sleep. MethodsData from the baseline and 2-year follow-up of the Adolescent Brain and Cognitive Development study were analyzed (n = 6227 for physical activity; n = 4151 for sleep). ACEs were assessed by parent report at baseline (mean age 9.9 years) with 3 levels: none, exposure to 1 ACE, and exposure to 2 or more ACEs. Objective measures of physical activity and sleep were assessed with an accelerometer at 2-year follow-up (mean age 11.9 years). Multivariate linear regression analyses were used to examine the relationship between ACEs and physical activity as well as sleep, adjusting for family income and sex. ResultsCompared to children with no ACEs, children with ACEs had fewer daily steps: 1 ACE (β = −323 (95% CI: −508 to −138), P < .001) and 2 or more ACEs (β = −417 (95% CI: −624 to −209), P < .001). ACEs were also associated with shorter sleep duration (minutes), although only for participants with 2 or more ACEs (1 ACE: β = −2.2 (−5.3 to 0.8), P = .16; 2 or more ACEs: β = −6.2 (95% CI: −9.6 to −2.7), P < .001). Rapid eye movement (REM) sleep specifically was reduced in participants with ACEs (1 ACE (β = −1.4 (−2.7 to −0.01), P = .05) and 2 or more ACEs (β = −2.3 (−3.8 to −0.8), P = .003). ConclusionsThere is a dose-response relationship between ACEs and reduced daily steps, total sleep duration, and REM sleep in preadolescents.
