Objective: This study aimed to analyze parents’ perceptions regarding adolescents’ screen use, signs of screen dependency, and its impact on sleep among 10- to 16-year-olds in the district of Leiria, Portugal. A descriptive–correlational, cross–sectional study was conducted in April 2024 using an online questionnaire completed by a non-probabilistic accidental sample of 616 parents or legal guardians. Nearly half of the respondents (48.2%) perceived adolescents as dependent on screens, while 68.7% believed that their screen time was excessive. Several behavioural signs consistent with digital dependence were reported. Increased screen use was significantly associated with shorter sleep duration, daytime sleepiness, and difficulties initiating sleep. Although many adolescents still achieved the recommended number of hours of sleep, those perceived as screen-dependent were more likely to experience compromised sleep quality and quantity. These findings reinforce the growing concern about adolescents’ digital habits and underscore the importance of implementing targeted health promotion strategies focused on responsible screen use and sleep hygiene among school-aged youth.

Human papillomavirus (HPV) vaccination is a cornerstone of cancer prevention across genders. In the United Kingdom (UK), the programme now includes boys, yet uptake remains below target, with persistent disparities by gender and region. This commentary examines the drivers of these gaps, including the historical framing of the HPV vaccine as a vaccine for girls, limited public awareness of boys’ eligibility, and challenges in school-based delivery. Gendered misconceptions, cultural norms, and inadequate communication continue to limit uptake in boys, while healthcare professionals, including general practitioners, dentists, and pharmacists, remain underused in supporting vaccine access and tackling parental hesitancy. Schools are central to equitable delivery, but teachers often lack training and possess low-to-moderate knowledge of HPV-related topics, including HPV vaccination availability for boys and HPV-related cancers affecting men. Drawing on health behaviour theory, we propose evidence-informed, multi-level recommendations to improve uptake, from gender-inclusive messaging and more efficient consent processes to digital engagement tools that support parents. We also highlight our ongoing research into parental attitudes toward HPV vaccination for boys aged 9–12 in England, which will inform future targeted interventions and policy development.

Schools constitute strategic settings for shaping eating behaviors among youth. Given the profound environmental, health, and social challenges associated with current food systems, there is an urgent need to explore dietary patterns that simultaneously support human well-being, ecological sustainability, and ethical principles. This comprehensive review provides a contemporary overview of the role of plant-based diets as an instrumental pathway to a healthier and more sustainable future by examining (i) environmental and social impacts of current food systems; (ii) the effects of plant-based diets on health; (iii) determinants of plant-based diet implementation in schools, including barriers and facilitators to their adoption; and (iv) the development of future-oriented dietary guidelines. Transitioning to plant-based diets, combined with sustainable agricultural practices, can reduce resource use and promote ecological sustainability. Promoting plant-based diets can also encourage the development of a more responsible and equitable social culture. Plant-based diets consistently provide metabolic, cardiovascular, and anti-inflammatory benefits across diverse populations, contributing to healthy weight and glycemic regulation. Well-planned plant-based diets may also improve cognitive function and promote psychological well-being. The integration of plant-based diets in schools is limited by barriers such as children’s food preferences, habitual eating patterns, peer influence, time and resource constraints, limited knowledge, cultural attachment to meat, and low family involvement. Conversely, facilitators including experiential learning, nutrition education, teacher and family engagement, social norms, ethical or environmental motivations, and institutional support promote acceptance and implementation. Ongoing research is required to refine dietary recommendations, assess long-term health outcomes, and ensure nutritional adequacy across pediatric populations. Continued evaluation of school-based interventions and policy frameworks will be essential to optimize the integration of plant-based diets and to monitor their health, ethical, and environmental impacts.
