    OBJECTIVE: Over the past decade, concurrent with increasing social media use (SMU), there has been a shift toward poorer sleep among adolescents in many countries. The purpose of this study was to examine the cross-national associations between adolescent SMU and sleep patterns, by comparing 4 different categories of SMU (nonactive, active, intense, and problematic use). DESIGN, SETTING, AND PARTICIPANTS: Data were from 86,542 adolescents in 18 European and North American countries that participated in the 2017/18 Health Behaviour in School-aged study. MEASUREMENTS: Mixed-effects linear regression models were used to examine cross-national associations between 4 SMU categories and adolescent sleep duration, bedtime and social jetlag derived from self-reported data. RESULTS: For all countries combined, nonactive SMU was associated with longer sleep, earlier bedtimes, and less social jetlag, compared to active SMU, although the differences were minor. By comparison, intense and problematic SMU were associated with less sleep and later bedtimes on both school and nonschool days, and greater social jetlag, compared to active SMU. While findings were relatively consistent between countries, some differences were observed, suggesting that the national and cultural context may be important in interpreting results. CONCLUSIONS: These findings suggest that both intense and problematic SMU are associated with poorer sleep patterns in adolescents across most countries. Further research is needed to identify effective policies, programs, and messaging to promote the healthy use of social media and prevent potential negative impacts on adolescent sleep.

    After the bell : adolescents' organised leisure-time activities and well-being in the context of social and socioeconomic inequalities
    (2021-06-10) Badura, Petr; Hamrik, Zdenek; Dierckens, Maxim; Gobiņa, Inese; Malinowska-Cieślik, Marta; Furstova, Jana; Kopcakova, Jaroslava; Pickett, William; Institute of Public Health; Department of Public Health and Epidemiology
    BACKGROUND: Previous research has linked adolescents' participation in organised leisure-time activities (OLTAs) to better health and well-being. It remains unclear whether these associations can be observed consistently across social and socioeconomic strata and countries. METHODS: The present study used nine nationally representative samples of adolescents aged 11, 13 and 15 years (total n=55 429) from the 2017/2018 Health Behaviour in School-aged Children survey from Europe and Canada. Regression models with mixed effects to account for nested nature of data were applied to estimate: (1) the associations of social and socioeconomic factors with OLTA participation; (2) strengths of the associations between breadth and pattern of OLTA participation with health and well-being indicators, after adjustment for the social and socioeconomic factors. RESULTS: Rates of OLTA participation varied by age, sex and country of adolescents. Participants from lower socioeconomic classes and non-nuclear families were less likely to participate in OLTAs across each of the nine countries. Moreover, breadth of OLTA participation was associated with higher well-being independent of socioeconomic status or family structure. All of the participation patterns were associated with higher life satisfaction, but sports (either alone or in combination with a non-sport OLTA) were also associated with fewer psychological complaints and excellent self-rated health. CONCLUSION: Adolescents' engagement in OLTAs was associated with adolescents' subjective well-being regardless of country, age, sex and variance in social and socioeconomic factors. Policies aimed at increasing adolescents' subjective well-being and OLTA participation should focus on adolescents from low socioeconomic classes and non-nuclear families.
