Abstract
Physical activity (PA), sleep, and limited sedentary behavior are all known components that promote health for children. While each of these components independently impacts health, they are not mutually exclusive. The 24-hour movement guidelines bring together these components to provide recommendations that encompass the whole day. These 24-hour guidelines include at least 60 minutes of moderate to vigorous physical activity (MVPA), several hours of structured and unstructured light physical activity (LPA), 9 to 11 hours of sleep, and less than 2 hours of recreational screen time (Tremblay et al., 2016). Using the 24-hour movement guidelines as a framework, this study examined how the weight status of children with and without autism spectrum disorder (ASD) was influenced by the number of recommendations met. 26 children with ASD and 24 neurotypical children between the ages of 6 and 9 years (M = 8.4) participated in this study. Height (cm), weight (kg), body fat (%) were measured. BMI percentiles were calculated for each child to classify weight status. PA was measured objectively using ActiGraph GT3X accelerometers. Using ActiLife 6 software, time spent in MVPA and LPA was determined using the Evenson (2008) cut points. Parents reported sleep and screen time. The majority of children in this research were of healthy weight status. However, the BMI percentiles of 38.5% children with ASD were classified as overweight or obese and 8.3% of neurotypical children were classified as overweight. Children with ASD had an average of 3 hours of LPA, 47.6 minutes of MVPA, 9.2 hours of sleep, and 3.1 hours of screen time per day. Whereas children without ASD had an average of 3.14 hours of LPA, 63.1 minutes of MVPA, 9.74 hours of sleep, and 1.43 hours of screen time per day. 23% of children with ASD met 4 recommendations, 50% met 3 recommendations, 23% met 2 recommendations, and 9% met 1 recommendation. Whereas 44% of children without ASD met 4 recommendations, 50% met 3 recommendations, and 6% met 2 recommendations. Compared to neurotypical children of the same age, children with ASD were more likely to be overweight or obese. On average, children with ASD spent less time engaged in MVPA and LPA and engaged in more screen time. Overall, children with ASD were less likely to meet the 24-hour movement recommendations.
