The 24-hour movement behavior guidelines recommend that children ages 5 to 17 years accumulate a minimum of 60 minutes per day in moderate to vigorous physical activity, spend no more than 2 hours per day in recreational screen time, and obtain 9 to 11 hours (5-13 years) and 8 to 10 hours (14-17 years) of sleep per night. The purpose of this study was to determine whether meeting the 24-hour movement behaviors were associated with dimensions of impulsivity. Data from this cross-sectional observational study were part of the first annual curated release of the Adolescent Brain Cognitive Development Study. Participants included 4524 children between the ages of 8 and 11 years. Children were assessed on eight different dimensions of impulsivity, such as their tendency to seek out thrilling experiences, to set desired goals, to respond sensitively to rewarding or unpleasant stimuli, and to act rashly in negative and positive moods. Results showed that adherence to individual movement behavior recommendations as well as combinations of adherence to movement behavior recommendations were associated with each dimension of impulsivity. Specifically, the results showed that children who met all three movement behaviors scored more favorably on 5 of the 8 dimensions of impulsivity, and that children who met the screen time and sleep recommendations scored more favorably on all 8 dimensions of impulsivity. These findings have important implications for pediatricians, psychiatrists, educators, parents, and policy makers as they suggest that strategies to limit recreational screen time while simultaneously promoting early, routine bedtimes and more sleep may enhance the treatment and prevention of impulsivity-related psychiatric disorders.
