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.

An understanding of the impact of the pandemic on their mental health is crucial in measures to promote the post-pandemic recovery. Using a person-centered approach, the current study aimed to identify mental health profiles in two cross-sectional samples of Finnish adolescents before and after the peak of the pandemic, and to examine how socio-demographic and psychosocial factors, academic expectations, health literacy, and self-rated health are associated with the emerging profiles. Methods and findings Surv…

Lasten ja nuorten sosiaalisen median ongelmatilanteet ja tarvittavat turvataidot

Kouluikäiset lapset ja nuoret viettävät päivittäin useita tunteja erilaisilla sosiaalisen median alustoilla (EU Kids, 2020). Keskeisenä kasvu- ja toimintaympäristönä sosiaalinen media (some) luo mahdollisuuksia muun muassa toimijuudelle, oppimiselle ja vuorovaikutukselle, mutta myös erilaisten ongelmatilanteiden rakentumiselle ja kohtaamiselle. Nettikiusaaminen, virheellisen tiedon tai vaarallisten some-haasteiden kohtaamisnen ovat esimerkkejä yleisistä somen ongelmatilanteista. Sosiaalisen median turvataidot ovat nykyajan kansalaistaitoja, joita voidaan opettaa kouluissa esimerkiksi terveystiedon oppitunneilla pelillisin keinoin. nonPeerReviewed

Problematic Social Media Use and Health among Adolescents

1) Background: The use of social media has become an integral part of adolescents’ daily lives. However, the intensive use of social media can develop into a health-threatening addiction, but unfavourable health consequences can occur even with less use. Social media user groups categorized as no-risk, moderate risk (of developing problematic behaviour), and problematic use were examined with reference to their prevalence, their associations with individual determinants and health, and the increased health risk between groups. (2) Methods: The Finnish nationally representative HBSC data (persons aged 11, 13, and 15, n = 3408) and descriptive and binary logistic regression analysis were appl…

Profiles of Internet Use and Health in Adolescence : A Person-Oriented Approach

(2) Methods: The study applied the Finnish nationally representative HBSC data (persons aged 11, 13, and 15, n = 3408), descriptive observation, latent class analysis, and multinomial logistic regression analysis. (3) Results: Entertainment activities (listening to music) and socially oriented activities (liking posts, talking online) were the most prevalent among adolescents, but gender differences emerged.

Adolescents’ online communication and well-being : Findings from the 2018 health behavior in school-aged children (HBSC) study

Background: Digital transformation has influenced all areas of adolescents’ lives, including the ways adolescents maintain friendships. Interpersonal communication is one of the most common activities while online. Online communication may provide adolescents with opportunities to expand their social contacts, but these encounters can be risky, especially when the communication is with unknown people on the internet. This study examined the associations between different forms of online communication behavior and well-being. Materials and methods: Data were collected from Finnish adolescents as part of the Health Behavior in School-Aged Children (HBSC) study in 2018. The participants were 3…

International perspectives on social media use among adolescents: Implications for mental and social well-being and substance use

In the present study, we aimed to explore the relationship between intensity of social media use (SMU), problematic SMU and well-being outcomes. Four categories of SMU were developed taking into account both intensity of use and problematic SMU simultaneously: non-active; active; intense; and problematic use. Using these four categories, we assessed associations between SMU and mental and social well-being, and substance use. Data from 190,089 respondents aged 11, 13, and 15 years from 42 countries involved in the Health Behavior in School-aged Children (HBSC) study were analyzed. With a slight cross-national variance, 78% of adolescents in the sample were classified as active or intense us…
