Young People's health-related learning through social media: What do teachers need to know?

International regulatory bodies have argued that young people should be better supported to engage safely, responsibly and effectively with social media. This paper considers ways in which the introduction of structured social media engagement in schools could bring educational benefits for young people, particularly in supporting them to deal with challenges relating to health and wellbeing. New evidence is provided on: (i) the value of social media as a health-related learning tool to bridge informal and formal learning contexts; (ii) how teachers should be supported to better understand and respond to young people's learning needs; and (iii) the school-based policies, expectations and resources that will help teachers to offer relevant support.

Review of policies to increase fruit and vegetable consumption and physical activity in 49 low- and middle-income countries.

BACKGROUND: Inadequate physical activity (PA) and consumption of fruits and vegetables (FV) are known risk factors for non-communicable diseases (NCDs). Consequently, the World Health Organization (WHO) encourages the development of policies to increase PA and FV consumption. We reviewed available policies between 2004 and 2013 to increase FV consumption and PA from a convenience sample of 49 LMICs. METHOD: Information on national policies were obtained from government ministries involved with the formulation of nutrition and PA policies, WHO databases and from PubMed and Scopus. RESULTS: Of the 49 countries, 57% had policies to increase FV consumption, and 76% had policies to promote PA. Policy reviews indicated strategies that focus on schools, communities, the general public, the environment, the economy, mass media and WHO recommendations. Of the 28 countries with FV policies, 18% had formulated policies that met the WHO recommendations for daily intake of FV. Likewise, of the 37 countries with PA policies, 24% had policies that promoted the WHO recommendations for daily PA. CONCLUSION: Greater progress has been made in developing policies to increase PA compared to policies to increase FV consumption in low- and middle-income countries. However, most countries are still lagging behind in developing policies to meet the WHO recommendations.

The unintended consequences of school-based health and nutrition policies: a systematic review.

Background: Significant funding and attention are directed toward school-based health and nutrition interventions. Less attention is given to the potential unintended consequences of these policies, especially those that target children and adolescents. This systematic review aimed to elucidate the unintended consequences of school-based health and nutrition policies in the United States. Methods: We conducted a systematic review, adhering to PRISMA guidelines, to analyze quantitative, qualitative, and mixed methods research conducted between January 2013 and September 2023. The search strategy encompassed three databases, identifying 11 articles that met the inclusion criteria. Results: Unintended consequences were organized into four themes: disordered weight control behaviors, parental discomfort or encouragement of disordered weight control behaviors, eating disorder triggers, and financial losses. The analysis of disordered weight control behaviors indicates limited impact on youth, and we noted limited consensus in the assessment of these behaviors. We observed parent concerns about BMI screening and reporting as well as apprehensions about privacy and efficacy. There were fewer articles addressing eating disorder antecedents, although there was evidence that some youths with eating disorders considered school health class a trigger of their disorder. One study was identified that found an increase in food waste following replacement of sugar-sweetened beverages. Implications: Findings underscore the importance of comprehensive evaluation and consideration of unintended consequences in the development and implementation of school-based health policies. Recommendations include further longitudinal research, integrating obesity prevention with eating disorder prevention, and de-implementation when unintended consequences potentially outweigh benefits, such as in BMI screening and surveillance.Systematic Review Registration: Identifier CRD42023467355. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=467355.

An evaluation of school-based e-cigarette control policies' impact on the use of vaping products.

INTRODUCTION: Electronic cigarette (e-cigarette) use among youth is common, and so efforts to regulate its use and availability are continually being made. The school environment represents an important domain for advancing health policy among youth populations. This study examines the impact of school-based e-cigarette control policies on student e-cigarette use in the context of a natural experiment. METHODS: Using three years of longitudinal student and school level data (2013/2014 to 2015/2016), from a sample of 69 secondary schools in Ontario, Canada, a generalized estimating equation approach examined the impact of school-based e-cigarette control policy changes on the prevalence of youth e-cigarette use. The main outcome of interest was current e-cigarette use, while covariates included age, gender, ethnicity, and amount of spending money in dollars per week the student has. Tests of proportion (t-tests) were used to examine whether there were any significant differences in the changes for each intervention school relative to the sample of schools that report no changes in school-level e-cigarette control policies. RESULTS: Estimates from the generalized estimating equation approach suggest that students had lower odds of using e-cigarettes in schools where an e-cigarette control policy was implemented. That is, the e-cigarette control policy decreased the adjusted odds of being an e-cigarette user (OR=0.68; 95% CI: 0.48-0.97). Examining school-specific impact, at four of six schools that had an e-cigarette control policy, the ban on the use of e-cigarettes may have lowered the prevalence of e-cigarette use. CONCLUSIONS: This is the first study to use longitudinal data to study school-level e-cigarette use and the impact of e-cigarette control policy. These results provide new evidence that school-level policies banning the use of e-cigarettes on school property may be effective in reducing e-cigarette use (or preventing it) in their current form, as seen in this natural experiment.
