Background: There is a gap in the literature regarding data on sexting among youth under the age of 16 whereas the problems related to this practice could affect them more because of their ongoing development. This study aims to determine the prevalence rate and characteristics of sending one's own sexually related image among middle-school teens.

Methods: Data were obtained from a web-based in-school survey conducted between October 2019 and February 2020. The sample comprised 3006 (mean age 13.7; 50.2% males) 10th-grade pupils in the canton of Vaud (Switzerland). Participants were asked "Have you ever sent a sexually related/sexy image of yourself?". Analysis of variance/chi-square tests and multinomial regression analyses were used to compare the groups.

Results: Overall, 93.0% reported never, 3.7% once and 3.3% several times. No gender differences were found. Sending was associated with older age, low academic performance, cyberbullying victimization and reception of unsolicited sexually related images.

Conclusions: Education and health professionals should be aware that it is necessary to discuss the theme, perhaps with a more global approach including pressure, consent, exchange of nonsexual images, and so on from an early age. The context and reasons for sending remain to be explored, particularly to determine if the pressure is greater at this age.

Background: Uncontrolled bleeding is the leading preventable cause of death after injury. Stop the Bleed (STB) is a bleeding control training with proposed expansion into schools. However, the attitudes of guardians, specifically those with past trauma/injury, towards expanding STB into schools are unknown.

Methods: A cross-sectional survey evaluated guardian attitudes towards STB training in high schools, and compared responses between guardians based on the experience of prior trauma. Logistic regression models evaluated the association between prior trauma and guardian-reported acceptability of STB training.

Results: Of 750 guardians who received the survey, 484 (64.5%) responded. Most guardians (95.3%) wanted their child trained. Few (4.2%) felt this training would be harmful; 44.9% felt their child might be held responsible if something went wrong, and 28.4% reported it might be too scary for their child. In adjusted models, guardians with prior trauma were more likely to want their child trained (odds ratio [OR] = 3.50, 95% confidence interval [CI] 1.11-15.50), and identify STB as important to them (OR = 4.07, 95% CI 1.66-12.26).

Conclusion: Our results support STB training in high schools, and guardians with a trauma history may be more likely to want their child trained. Further work to understand the perceived potential harm, and work to design trauma-informed first-response trainings is warranted.

Background: To determine if school engagement is a viable target for early prevention of adolescent substance use, this study investigated whether school engagement in early adolescence (ages 12-14) is a cause of alcohol and cannabis use during middle to late adolescence (ages 15-19).

Methods: To facilitate causal inference, inverse probability of treatment weights (IPTWs), which are based on estimated probabilities of treatment selection (ie, school engagement), were created based on a robust set of potential confounders. Using the IPTWs, a cumulative link mixed model was fit to examine the impact of school engagement on alcohol and cannabis use among an ethnically diverse sample of adolescents (N = 360).

Results: School engagement was associated with a lower level of alcohol and cannabis use from age 15 to 18. School engagement was not associated with change in alcohol and cannabis use over time, suggesting that school engagement emits its effect early in the developmental course of substance use and offers protection throughout adolescence.

Conclusions: This study supports a compensatory role of early school engagement in substance use across middle and late adolescence. School engagement is a malleable factor and thus offers an avenue for prevention efforts.

Background: School belonging has been linked to students' health and well-being. As US schools become more ethnically diverse, it is important to understand how schools can contribute to a sense of belonging for students from all ethnic groups.

Methods: The present study examines the association between school interethnic climate, school belonging, and 3 well-being indicators (psychological, physical, and academic) among 657 10th graders across 2 states.

Results: Positive school interethnic climate was associated with stronger feelings of school belonging, and was indirectly associated with better psychological adjustment, fewer physical symptoms, and better grades via school belonging. There were no differences between White and non-White students in the findings.

Conclusions: Focusing on fostering a positive interethnic atmosphere may be a useful target for schools to support students' health and well-being as well as academic performance.

Background: Sport-related concussions are a major public health problem with only 50% of concussed teens reporting their symptoms. The purpose of this systematic review was to identify individual and institutional factors that contribute to concussion knowledge, attitude, and reporting behaviors among US high school athletes.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol was used to direct the process of this systematic review. A search for English, peer-reviewed, quantitative studies published between 2010 and 2020 was conducted in 5 scholarly databases. The Joanna Briggs Critical Appraisal Tools were used to assess study quality.

Results: Twenty-two studies met criteria for inclusion in this systematic review. The study designs were mostly cross-sectional (N = 18). Synthesis revealed individual factors including gender, age, race/ethnicity, grade level, and concussion history were associated with differences in concussion knowledge, attitude, and/or reporting behaviors. Institutional factors identified included school location, concussion education, access to an athletic trainer, sport played, and team climate. Six studies found concussion education had a positive impact on knowledge and reporting behaviors.

Conclusion: This systematic review identified certain populations which may be more vulnerable to underreporting concussion symptoms; therefore, a targeted approach to education and management may be more effective.

Background: School environments are important to consider for children's health. This study aims to determine if childhood peer bullying and school connectedness are associated with adolescent adiposity.

Methods: A total of 3377 children from the age 9 child interview of the Fragile Families and Child Wellbeing Study had self-reported bullying and school connectedness data at age 9, height and weight measured at ages 9 and 15, and waist circumference was measured during an age 15 home visit. Linear regression models estimated the association between bullying and school connectedness and (1) change in BMI between age 9 and 15, and (2) waist circumference at age 15. Models were stratified by sex.

Results: Girls had larger increases in body mass index (BMI) when experiencing low school connectedness, and students that experienced both bullying and low school connectedness had larger increases in BMI. Girls had larger waist circumferences for increased levels of bullying, low connectedness, and experiencing both.

Conclusions: School environments may play a role in the development of increased adiposity and there may be gender differences in the types of factors that are important to consider, particularly for central adiposity. Positive and engaging school environments can help support students' development and healthy behaviors.
