    Future research is needed to verify these preliminary findings and determine the directionality of relationships observed, and experimental studies are needed to determine whether promoting either increased steps per day or intensity of physical activity can improve social emotional functioning in the early years.

  4. Longitudinal association between movement behaviours and depressive symptoms among adolescents using compositional data analysis.


    Isotemporal substitution estimates indicated that decreasing screen time by 60 minutes/day and replacing that time with 60 minutes of additional sleep is associated with the largest change in depressive symptoms across all subgroups.
