  1. Longitudinal associations between different types of screen use and depression and anxiety symptoms in adolescents


    Higher screen time was longitudinally associated with higher anxiety and depression symptoms at one-year follow-up in adolescents. Time-change associations between screen usage and depressive and anxiety symptoms were observed. Also, associations differed based on sex and screen type, whereby greater increases in screen use predicted greater emotional distress. Findings from this prospective analysis suggest that screen time is an important determinant of anxiety and depressive symptoms among adolescents. Future studies are recommended to help inform programs promoting screen time reduction with a goal to enhance adolescents’ mental health.

  2. Evidence supporting a combined movement behavior approach for children and youth’s mental health – a scoping review and environmental scan


    There is a wealth of knowledge on the association between combined MB and MH though only one tool examined how combined MB and MH are associated. Efforts are warranted to better track and intervene on population and individual-level 24-h MB for MH promotion and disease prevention.

  3. Appearance satisfaction mediates the relationship between recreational screen time and depressive symptoms in adolescents


    Our results indicate that appearance satisfaction medi-ated the direct effect of recreational screen time on depressive symptoms, recreational screen time was sig-nificantly related to lower appearance satisfaction, which was significantly predictive of more severe depres-sive symptoms. As such, findings warrant randomized controlled trials designed to determine whether modu-lating screen time may be an efficacious strategy to reduce appearance dissatisfaction and depressive symp-toms during adolescence.

  4. Sociodemographic Factors Associated With Objectively Measured Moderate- to Vigorous-intensity Physical Activity in Adults With Type 2 Diabetes: Cross-sectional Results From the Canadian Health Measures Survey (2007 to 2017)


    Sociodemographic factors are strongly associated with levels of MVPA in adults with type 2 diabetes. Sociodemographic information should be routinely collected by clinicians and used to inform more tailored and effective interventions for this patient population.

  5. Interindividual Differences in Trainability and Moderators of Cardiorespiratory Fitness, Waist Circumference, and Body Mass Responses: A Large-Scale Individual Participant Data Meta-analysis


    Despite the widespread assumption that individuals respond differently to exercise, the current IPD meta-analysis provided evidence in favour of no interindividual differences in trainability for CRF, waist circumference, and body mass. Although exercise training per se may not explain why individuals differentially benefit from completing ostensibly the same dose of exercise training, completing exercise training will increase the probability that an individual will experience a meaningful change in CRF, waist circumference, and body mass.
