Achieving the recommended daily level of physical activity (PA) in adolescent boys and girls helps improve their cardiovascular health, maintain a healthy body weight, promote mental health. The purpose our study was to determine whether there were statistically significant differences between aged 12 15 years with respect age amount PA on different days week. sample included 606 7th, 8th, 9th grade students from four Slovenian elementary schools who participated by completing questionnaire (IPAQ; International Physical Activity Questionnaire, 2006). We used quantitative research approach method causal-non-experimental. Shapiro-Wilk test data normally distributed at risk (p > 0.05). Because non-normal distribution variables < 0.001), non-parametric Mann-Whitney genders, Kruskal-Wallis groups. Boys significantly more active than all week except Wednesday (Mon.: p=0.018; Tues.: p=0.001; Thurs.: p=0.020; Fri.: p=0.015, Sat.: p=0.012; Sun.: p=0.001). Significant levels seventh-, eighth-, ninthgraders occurred only Sundays (p<0.001), changing student age. study's findings that are raise concerns about gender participation during this critical developmental period. Such may contribute long-term health consequences perpetuate inequalities overall fitness well-being. observed adolescence highlight need for targeted interventions strategies among girls. Addressing underlying factors lower is essential promoting equitable inclusive promotion.

Nowadays, children and adolescents are exposed to digital media (DM) from an early age. Therefore, specific guidelines have been published by the World Health Organization, whose aim is limit daily screen time (ST) viewing. However, during COVID-19 pandemic, a rise in DM use, consequently ST viewing, was observed. More more aspects of modern life thought be affected excessive Accordingly, this review document health effects viewing on adolescents. A narrative performed searchable databases. In total, 43 original articles were considered. Excessive correlated with increased risk for obesity other cardiometabolic factors, mental health, unhealthy dietary habits eating disorders, problems development child–parent relationships. Sleep, physical activity, eyesight, headaches, musculoskeletal system negatively as well. effect weighted type used way types used. Other confounding factors reported. There evidence suggest negative correlation between youth exists. Nevertheless, research needed if established.

Recently the Swedish Public Health Agency published recommendations of a maximum two-to-three hours daily leisure screen time for adolescents aged 13–18, partly to promote better sleep (2024-Sep-02). Biologically and socially, adolescence is characterized by belated times, depressive effects can arise through displacements. Theorized links between time, sleep, depression, merited examination four mediators determine their relative importance which them mediate future depression. Hypotheses were preregistered. Three-wave psychometric health data collected from healthy students ( N = 4810; 51% Boys; ages 12–16; 55 schools; n 20 26 Stockholm municipalities). Multiple imputation bias-corrected missing data. Gender-wise Structural Equation Modelling tested facets as competing (quality, duration, chronotype, social jetlag). The primary model result included three first achieve acceptable fit indices (RMSEA 0.02; SRMR 0.03; CFI 0.95; TLI 0.94). Screen deteriorated within months effect sizes varied Beta weights ranged: 0.14–0.30) but less genders. Among boys, at baseline had direct adverse on depression after twelve p <0.038). girls, was mediated quality, chronotype (57, 38, 45% mediation). Social jetlag remained non-significant. This study supports modernized ‘screen-sleep-displacement theory’. It empirically demonstrates that screen-sleep displacements impact several aspects simultaneously. Displacements led elevated symptoms among girls not boys. Boys may be more prone externalizing due loss. Results could mirror potentially beneficial public national recommendations.

Changes in lifestyle during the pandemic may have predisposed adolescents to vulnerability poor mental health. This study aims evaluate these changes and their association with course of anxiety. A prospective was conducted 153 participants (16 years old, 72% female) who were assessed before (T0, November 2019-January 2020) one year later (T1, April-May 2021). Lifestyle habits (free-time activities, maladaptive behaviors, sleep, screen use) anxiety measured. Data concerning experiences related COVID-19 family relations lockdown collected. worsening found. Of note, pattern associations between quite different two time-points, suggesting that purpose impact some be changed after pandemic. Regression analyses showed increases associated sleep problems, heightened efforts reduce time, loneliness. Pathway analysis revealed absence cross-lagged effects among anxiety, use, while concurrent variables found both assessments. These results suggest possible long-term Risk-factors identified habits, thus contributing identifying targets for interventions.
