Associations of meeting 24-hour movement behavior guidelines with social and emotional function in youth with ASD/ADHD

Abstract

BackgroundThe 24-hour movement behavior (24-HMB) guidelines recommend that children and adolescents (youth) should limit screen time (ST), get an adequate amount of sleep (SL), and engage in sufficient physical activity (PA) to ensure health and healthy development. Meeting 24-HMB guidelines is associated with positive mental health outcomes (e.g., social and emotional function) in the general population. However, it is unclear whether such findings extend to youth with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Thus, we examined associations of meeting 24-HMB guidelines with social and emotional function in youth with comorbid ASD/ADHD. MethodsData from the 2020–2021 National Survey of Children's Health - a U.S. national, population-based, cross-sectional study – were used. We extracted and analyzed data on youth (aged between 6 and 17 years) diagnosed with comorbidity of ASD/ADHD. Data on movement behaviors (PA, ST, and SL) and specific outcome variables (social function and emotional function) were collected through caregiver-proxy reports. Logistic regressions were performed to examine the associations between meeting 24-HMB guidelines and social and emotional outcomes adjusting for covariates (e.g., age, sex, ethnicity, weight status, birth status, socio-economic status, and receiving medication/behavioral treatment). ResultsAmong 979 children and adolescents with comorbid ASD/ADHD, only 3.8 % met all three 24-HMB guidelines. In total, 45.0 % of participants met at least one guideline, and 25.5 % of those met at least two guidelines. Compared to those who did not meet any 24-HMB guidelines, meeting SL + ST guidelines was significantly associated with lower odds of poorer social function (being bullied: OR = 0.3, 95%CI [0.1–0.7]; arguing: OR = 0.2, 95%CI[0.1–0.4]). Furthermore, meeting PA + ST + SL guidelines was associated with lower odds of poorer emotional function (depression: OR = 0.5, 95%CI[0.3–0.7]). ConclusionMeeting 24-HMB guidelines was associated with better social and emotional function in U.S. youth with comorbid ASD/ADHD; however, currently very few with comorbid ASD/ADHD meet all 24-HMB guidelines. These results emphasize the importance of promoting adherence to the 24-HMB guidelines among youth facing the challenges of comorbid ASD/ADHD. These cross-sectional findings point to the need for further empirical evidence from longitudinal studies to support our conclusions.
