    Background: Physical activity and sedentary behavior are related with psycho-social variables among youth, however its relationship with bullying victimization is unclear. The aim of the study was to clarify the associations between physical activity and sedentary behaviors with bullying victimization among children and adolescents. Methods: Two independent authors searched in four databases. The studies were selected/included only if participants were children and/or adolescents and the relationship between physical activity and/or sedentary behavior with bullying victimization was reported. Random-effects meta-analyses were used. Results: A total of 18 cross-sectional studies (including 386,740 children and adolescents, 51.8% females) were reviewed. Our study found that not meeting the physical activity guidelines (Odds Ratio [OR] = 1.14, 95% confidence interval [CI], 1.04 to 1.23) and excessive sedentary behavior (i.e., 2 h per day or more of screen time) (OR = 1.21, 95% CI, 1.14 to 1.28) were associated with 14 and 21% higher bullying victimization, respectively. Consistent associations were also found when we analyzed specific forms of bullying for sedentary behavior, including traditional and cyberbullying. Conclusions: The present study establishes the first quantitative framework for understanding the influence of physical activity and sedentary behavior on bullying victimization, and lays the groundwork for future studies and interventions aimed to its promotion.

    Physical activity, screen time and subjective well-being among children
    (Elsevier Doyma, 2020-05) García-Hermoso, Antonio; Hormazábal-Aguayo, Ignacio; Fernández-Vergara, Omar; Olivares, Pedro R.; Oriol-Granado, Xavier
    Background/Objective: The aim of the study was to explore the differences between physical activity and/or screen time levels on cognitive (Life satisfaction LS) and affective (Positive affect, PA and Negative affect NA) components of subjective well-being (SWB) in children. Method: This cross-sectional study enrolled 1,540 children (1,040 boys, 8–12 years old). LS, PA, NA, physical activity and screen time were assessed with validated questionnaires. Results: Children who reported 3 days per week of physical activity or less had lower LS and PA than counterparts with ≥6 days of physical activity per week (p < .05). Participants who reported 2 hours per day or less of screen time had lower NA than counterparts with 4 hours per day or more of screen time (p < .05). Also, children who meet physical activity guidelines have higher LS and PA compared to inactive peers, even with high screen time. In contrast, excessive screen time was also related with NA independent of the level of physical activity. Conclusions: Our findings suggest that physical activity is related with positive feelings and LS, but does not eliminate the effect of screen time on negative feelings among Chilean children.
