INTRODUCTION: The cognitive benefits of physical activity (PA) are well-documented. Yet, boys typically spend more time in PA during adolescence than girls, and the gender differences concerning cognitive benefits associated with PA remain elusive. Compositional data analysis (CoDA) is the statistical tool that assesses the interaction between time spent in PA and other movement behaviors that make up the 24-hour day in a single statistical model. We investigated how 24-hour movement behaviors are associated with cognitive function in boys and girls using CoDA. METHODS: Early adolescents (N=4082; F=1997; aged 11.97 ± 0.65 years) from the Adolescent Brain Cognitive Development (ABCD) study at Year 2 were analyzed. CoDA was used to explore predicted changes in cognitive function (NIH Toolbox) with 60-min time reallocations between sleep, sedentary behaviors, light PA, and moderate-to-vigorous PA (MVPA), obtained by wrist-worn accelerometer. Estimated cognitive function response curves were based on significant regressions from isometric log-ratio coordinates of time spent in movement behaviors, adjusted for covariates (age, puberty, household income, BMI). RESULT: Significant R2 changes were observed for picture vocabulary (girls: adj-R2=0.24,p<0.001; boys: adj-R2=0.19,p<0.001), flanker (girls: adj-R2=0.05,p<0.001; boys: adj-R2=0.04,p<0.001), and oral reading tasks (girls: adj-R2=0.14,p<0.001; boys: adj-R2=0.13,p<0.001). CoDA with 95% CI revealed that a 60-min increase in MVPA among girls, but not boys, was significantly associated with improved picture vocabulary (0.10, 6.33), flanker (1.03, 7.05), and oral language performance (0.04, 5.01). CONCLUSION: CoDA reveals that increasing MVPA by 60 minutes a day in early adolescent girls is associated with improved cognitive functioning.
