OBJECTIVES: This repeated cross-sectional study aimed to (a) report trends in adolescents' perceived family, friend, classmate, and teacher support, (b) estimate the extent to which each source of support related to life satisfaction across space and time, and (c) ascertain whether sociodemographic factors moderated the relationship in question. METHODS: We relied on data pertaining to the 2013/14, 2017/18, and 2021/22 waves of the Health Behaviour in School-aged Children study. The examined sample covered 44 countries and regions (n = 716,083; MAGE = 13.6; SDAGE = 1.64; 50.7% female). RESULTS: The level of all sources of perceived social support slightly decreased over the examined period (all ω2 < .01). Family support involved the largest association with life satisfaction (β = 0.16); friend support, the lowest one (β = 0.03). These associations varied only tenuously across space and time. Sociodemographic factors moderated the link between perceived social support and life satisfaction to a negligible-to-weak extent. CONCLUSION: Levels of perceived social support and their associations with life satisfaction subtly changed. Future research may attempt to pinpoint the macrosocial levers of these temporal dynamics.

INTRODUCTION: There is a consensus that adolescents' participation in organized leisure-time activities (OLTAs) is pro-developmental and beneficial for youth mental health. While enjoyment in OLTA is commonly regarded as positive, the role of obligation in the context of adolescents' OLTA has been scarcely researched. The present study investigated how these theoretically contradictory experiences (enjoyment and/or obligation) in OLTA participation relate to adolescents' wellbeing and incidence of psychological complaints accounting for their possible co-occurrence. METHODS: A nationally representative sample of 14,128 eleven-fifteen-year-old adolescents (49.7% girls) drawn from the Czech 2021/2022 Health Behaviour in School-aged Children cross-sectional study was used. A series of multivariate regression analyses assessed how perceptions of obligation and enjoyment in OLTA related to wellbeing and occurrence of psychological complaints. A person-centered approach derived groups of respondents on the basis of their perceptions of obligation and enjoyment. RESULTS: Regression analyses, controlled for sociodemographic and family environment factors, and dimensions of OLTA participation, indicated that adolescents enjoying their OLTA displayed more favourable mental wellbeing reports. In contrast, perceptions of obligation were only weakly associated with more frequent psychological complaints and not at all with wellbeing, unless adolescents also reported the lack of enjoyment. CONCLUSIONS: Enjoyment in OLTA plays a pivotal role in the association between OLTA participation and mental health, whereas the role of obligation is far less pronounced. In fact, if adolescents do not enjoy their participation, but feel obliged to participate, their self-assessed mental wellbeing is comparable to their peers not participating in OLTA at all.

Cíl: Hlavním cílem studie je zjistit změny v prevalenci obezity u reprezentativního souboru české mládeže mezi lety 2018 a 2022 a její aktuální koreláty s ohledem na socioekonomický status (SES) rodin adolescentů. Metodika: Národně reprezentativní soubor 24535 adolescentů ve věku 11–15 let (n = 11629/129062018/2022; chlapci: 50,4/50,6 %2018/2022) byl sestaven z posledních dvou cyklů online dotazníkového šetření realizovaného v letech 2018 a 2022. SES rodin zúčastněných adolescentů byl kategorizován pomocí Škály rodinného blahobytu. Obezitu reprezentuje interval > 97 % v percentilovém grafu Body Mass Indexu Světové zdravotnické organizace diferencovaný dle pohlaví a věku adolescentů. Rozdíly v prevalenci obezity adolescentů ze všech SES kategorií rodin byly testovány pomocí χ2-testu. Míra vlivu korelátů obezity adolescentů v roce 2022 byla analyzována pomocí vícenásobné logistické regresní analýzy. Výsledky: Mezi lety 2018 a 2022 nebyl u dívek ani chlapců v žádné kategorii SES rodin zjištěn signifikantní přírůstek v prevalenci obezity. U adolescentů z rodin s nízkým SES byla zaznamenána signifikantně nejvyšší (p < 0,001) prevalence obezity (11 %CHLAPCI a 5,8 %DÍVKY) ve srovnání s ostatními SES kategoriemi adolescentů. Mezi adolescenty z rodin s nízkým SES mají signifikantně nižší šanci výskytu obezity jedinci každodenně realizující pohybovou aktivitu (PA) střední až vysoké intenzity (p < 0,005) či 3krát týdně vysoce intenzivní PA (p < 0,05) než jejich méně aktivní vrstevníci. Vynechávání snídaní významně (p < 0,05) zvyšuje šanci výskytu obezity, ale pouze u adolescentů z rodin s nízkým SES. Kratší „screen time“ významně snižuje (p < 0,05) šanci výskytu obezity u všech SES kategorií adolescentů. Závěry: Obezita, jako výsledek dlouhodobé pozitivní energetické bilance zprostředkované nevyváženým chováním, je nejvýrazněji zastoupena u adolescentů z rodin s nízkým SES. Potvrdilo se, že významně nižší šance výskytu obezity adolescentů z rodin s nízkým SES je asociována s pravidelným prováděním doporučované PA, kratší dobou ST a nevynecháváním pravidelného snídání.

Objective: The main objective of the study is to determine changes in the prevalence of obesity in a representative cohort of Czech adolescents between 2018 and 2022 and its current correlates with respect to the socioeconomic status (SES) of adolescents’ families. Methods: A nationally representative sample of 24535 adolescents aged 11–15 years (n = 11629/129062018/2022; boys: 50.4/50.6%2018/2022) was drawn from last two cycles of an online questionnaire survey conducted in 2018 and 2022. The SES of the families of the participating adolescents was categorised using the Family Affluence Scale. Obesity was represented by > 97% on the age-differentiated World Health Organization Percentile Body Mass Index charts differentiated by gender and age of adolescents. The chi-square tests (χ2) were performed to assess differences in prevalence of obesity in each gender and SES categories of adolescents between 2018 and 2022. Multiple logistic regression analysis was used to analyse the relationship between different correlates and obesity in adolescents in 2022 separately for boys and girls. Results: There was no significant increase in the prevalence of obesity among girls or boys in any SES family category between 2018 and 2022. Adolescents from low SES families had the significantly highest (p < 0.001) prevalence of obesity (11%BOYS and 5.8%GIRLS) compared to other SES categories of adolescents. Among adolescents from low SES families, individuals who engaged in daily moderate to vigorous physical activity (PA) (p < 0.005) or 3 times per week vigorous PA (p < 0.05) had significantly lower odds of obesity than their less active peers. Skipping breakfast significantly (p < 0.05) increased the odds of obesity, but only in adolescents from low SES families. Shorter screen time significantly reduced (p < 0.05) the odds of obesity in all SES categories of adolescents. Conclusions: Obesity, because of long-term positive energy balance mediated by imbalanced behaviour, is most pronounced in adolescents from low SES families. It was confirmed that significantly lower odds of obesity in adolescents from low SES families are associated with regular practice of recommended PA, shorter ST duration and not skipping regular breakfast.

BACKGROUND: The main aim of the study is to examine changes in the prevalence of obesity in Czech adolescents between 2018 and 2022 and its current non-genetic correlates with respect to the adolescents' families'socioeconomic status (SES) in 2022. METHODS: The sample of 24,535 adolescents (n = 11,629/12,9062018/2022; boys: 50.4/50.6%2018/2022) aged 10.5-16.5 years that was analysed was drawn from two nationally representative cohorts of Czech youngsters from the last two cycles of the Health Behaviour in School-aged Children (HBSC) online questionnaire survey from 2018 to 2022. Obesity is represented by the > 97th percentile interval on the World Health Organization Body Mass Index percentile chart, with distinctions by sex and the age of adolescents. The differences in the prevalence of obesity between boys and girls from all SES family categories in 2018 and 2022 were tested using a chi-square test (χ2). Multiple logistic regression analysis with repeated measures was used to analyse correlates of obesity in 2022. RESULTS: Between 2018 and 2022, there was no significant difference in the prevalence of obesity in girls or boys in any of the SES categories of families. Adolescents from low-SES families have the highest prevalence of obesity, 11% for boys and 5.8% for girls, significantly higher (p < .001) than its prevalence among adolescents from high-SES families, by + 4.8% points for boys and + 3.9% points for girls. Among adolescents from low-SES families, individuals who engaged in moderate-to-vigorous physical activity (PA) daily (p < .005) or vigorous PA three times per week (p < .05) were significantly less likely to be obese than their less active peers. Skipping breakfast significantly (p < .05) increased the odds of obesity, but only among adolescents from low-SES families. Shorter screen time (ST) significantly (p < .05) reduced the odds of obesity for all categories of adolescent SES. CONCLUSIONS: Obesity is most pronounced in adolescents from low-SES families as a result of a long-term positive energy balance mediated by unbalanced behaviour. Significantly lower odds of obesity in adolescents from low-SES families were confirmed to be associated with regular practice of the recommended PA, shorter ST, and not skipping breakfast.

OBJECTIVE: Long-term isolation, including lockdowns and quarantines, may have a distressing effect on anyone experiencing it. Adolescent brain architecture is very sensitive to environmental adversities, and the mental health development of adolescents may be particularly vulnerable during the pandemic era. In order to better understand the triggers for perceived adolescent stress (PSS) during the COVID-19 lockdown, the present study aimed to assess the effects of social well-being and changes in time use during the lockdown, as well as the family COVID experience of adolescents. METHODS: The sample for this study comprised n = 3,440 adolescents (54.2% girls; mean age = 13.5 ± 1.6 years). Bayesian correlations between PSS, health and well-being variables were assessed. PSS was then modeled as an outcome variable in a series of nested Bayesian multilevel regression models. RESULTS: The negative impact of the COVID-19 lockdown was more apparent in girls. PSS was moderately correlated with adolescent health and well-being. The strongest predictor of higher level of PSS was frequent feeling of loneliness. On the contrary, lower level of PSS was most associated with having someone to talk to. CONCLUSION: Long-term social isolation of adolescents could be harmful to their mental health. Psychological coping strategies to prevent the consequences of social isolation and development of mental health problems should be promoted on the individual, family, and even community level.

Background/Objective: The second edition of the Czech Republic's Report Card on Physical Activity for Children and Youth was released in 2022. This paper describes the development of the Report Card and presents a comprehensive summary of the main findings. Methods: The multi-level search strategy was developed by the national expert panel to identify the available sources that provide data related to the physical activity of Czech children and adolescents. The data were used to assign grades to ten core and two additional indicators. Results: A total of 28 sources provided data that allowed grades to be assigned to 11 out of the 12 indicators. Grade B was assigned to six indicators (School: B+, Community and Environment: B, Organized Sport and Physical Activity: B-, Active Transportation: B-, Family and Peers: B-, Sleep: B-), grade C to three indicators (Overall Physical Activity: C+, Active Play: C, Physical Literacy: C), and grade D to two indicators (Government: D+, Sedentary Behaviors: D). No grade for the "Physical Fitness" indicator could be assigned due to a lack of data collected in the reference period 2018-2019. Conclusions: Although the family, school, and built environment provided a variety of opportunities to be physically active, a high proportion of children and adolescents did not meet the current physical activity guideline and were exposed to excessive sedentary behavior. A multisectoral and multidisciplinary response is required to reduce the health and economic burden of physical inactivity and excessive sedentary behavior among Czech children and adolescents.

Objectives: This study aimed to analyze the relationships among exclusion from PE, gender, and bullying in adolescents with specific developmental disorder of scholastic skills (SDDSS) aged 11, 13, and 15 years in Czechia. Methods: In total, the final research sample consisted of 13,953 students (49.4% boys) from the 2013/2014 Health Behaviour in School-aged Children survey. Chi-square tests and regression models stratified by presence of SDDSS diagnosis were used to assess the relationships between non-involvement in PA and bullying. Results: Students diagnosed with SDDSS (12.4% of the sample) were more likely to be excluded from physical education (PE) than students without this diagnosis. This exclusion was associated with higher odds of bullying victimization and perpetration. Our findings further showed that male gender plays a significant role for bullying perpetration for both groups (with and without SDDSS) investigated in the present study. Conclusion: Higher likelihood of aggressive behavior occurs in students who are excluded from PE, including students with SDDSS.

PURPOSE: This study aims to identify distinct typologies of joint family activities and the associations with mental health and wellbeing among adolescents across four countries from the World Health Organization European region. METHODS: The 2017/2018 data from adolescents from Armenia (n = 3,977, Mage = 13.5 ± 1.6 years, 53.4% female), Czechia (n = 10,656, Mage = 13.4 ± 1.7, 50.1% female), Russia (n = 4,096, Mage = 13.8 ± 1.7, 52.4% female), and Slovakia (n = 3,282, Mage = 13.4 ± 1.5, 51.0% female) were collected in schools. The respondents self-reported their participation in joint family leisure-time activities, life satisfaction, psychological and somatic complaints, as well as a range of demographic and family situational factors. Stratified by countries, latent class analysis identified typologies of joint family activities, and logistic regression models explored cross-sectional associations with life satisfaction, and psychological and somatic complaints. RESULTS: Three typologies were identified across each of the four countries, distinguished by low, moderate, and high levels of family engagement. Adolescents with higher family engagement generally reported greater life satisfaction and fewer psychological complaints compared to those with lower family engagement. Russian adolescents in the high family engagement typology reported fewer somatic complaints compared to those with low family engagement. In addition, adolescents from Czechia and Russia showing moderate family engagement also reported fewer psychological complaints compared to those in the low family engagement typology. DISCUSSION: Our findings from four countries suggest that adolescents with high family engagement have greater life satisfaction and fewer psychological complaints, pointing toward a need for interventions to support family engagement among adolescents. Further research is needed to fully explore underlying mechanisms.

OBJECTIVES: Recent literature indicates a decline over time in adolescent mental wellbeing but results are inconsistent and rely mainly on data from Western societies. This study investigates time trends in adolescent mental wellbeing (psychological and somatic complaints, life satisfaction) among Czech adolescents and explores the moderating role of gender, age and socioeconomic status. METHODS: Nationally representative data from 29,376 Czech adolescents (50.8% girls, mean age = 13.43; SD = 1.65) across five Health Behaviour in School-aged Children (HBSC) surveys (2002, 2006, 2010, 2014, 2018) were used. Hierarchical regression models estimated national trends in adolescent mental wellbeing and established the moderating role of gender, age and socioeconomic status. RESULTS: From 2002 to 2018, an increase in the psychological complaints was observed. Life satisfaction decreased over time up to 2014 only, whereas somatic symptoms increased until 2010, followed by a decline in 2014 and 2018. Girls, older adolescents and those from low family affluence reported poorer mental wellbeing. Gender gap increased over time for psychological complaints and life satisfaction. Socioeconomic inequalities gap remained stable over the investigated timeframe. CONCLUSIONS: Our findings do not provide evidence for substantial temporal changes in mental wellbeing among adolescents in the Czech Republic. Yet, the increase in psychological complaints has been consistent which is an indicator of a small decline over time in adolescent mental wellbeing. Furthermore, the gender gap in mental wellbeing increased over time, whereas the age and socioeconomic differences remained relatively stable. This calls for the attention of public health professionals and policy makers from the Czech Republic.
