FACTORS ASSOCIATED TO UNHEALTHY SEXUAL BEHAVIOURS AMONG PORTUGUESE ADOLESCENTS: 2018 HBSC STUDY

Practicing sexual intercourse (SI) under the influence of alcohol or drugs has been identified as an unhealthy sexual behaviour. The sample consisted of 5695 adolescents, of which 46.1% were males, with a mean age of 15 years old. The measures consisted of asking the adolescent if he or she had ever had SI, age of 1st SI, condom use at last SI, SI under the influence of alcohol or drugs and HIV testing. Most adolescents reported having never had SI (77.0%). Among those who responded affirmatively, they referred having had their 1st SI at 15 years old. A significant minority reported not having used condom at last SI (34.1%) and having had SI under the influence of alcohol or drugs (14.5%). It was noticeable that males, adolescents with high SES, those who reported not having used condom at last SI, those not having been HIV tested, those who consider themselves fat, smoke daily, and scored lower in emotional sensitivity and quality of life were those who were more likely to have reported having had SI under the influence of alcohol or drugs. Adolescents who reported having had SI under the influence of alcohol or drugs have multiple risk behaviours. These results may account for important changes in educational and health policies, directed towards the development of personal and social skills, the importance of adolescents’ quality of life and the activation of all the support structures where adolescents are involved and that are somewhat responsible for promoting a healthy lifestyle.

Prevalence and Social Inequality in Youth Loneliness in the UK

Using data from the English arm of the Health Behaviour in School-aged Children (HBSC) study, we examined the prevalence of loneliness for school-aged adolescents and how it is linked to social inequalities. The HBSC study collects data from 11-, 13-, and 15-year-olds, and is repeated every four years, allowing the exploration of prevalence rates of loneliness pre COVID-19 pandemic for comparison. We also explored whether loneliness was associated with socio-economic status (SES) and linked to academic attainment and health complaints. The total sample was 14,077 from 156 schools in England. Findings revealed a stable prevalence rate of 8.2% for loneliness from 2006 to 2014. We also found, across all survey years, (1) those aged 15 years were significantly lonelier than younger peers, (2) those who reported lower SES were lonelier than their more well-off peers, and (3) higher loneliness was associated with being ‘”below average” academically and reporting more health complaints. Conclusions: These prevalence data enable researchers, policymakers, and others to make comparisons with prevalence rates during the COVID-19 pandemic to explore whether there have been increases in loneliness among school-aged adolescents. Loneliness was consistently related to social inequalities, suggesting that targeted interventions that include whole systems changes are needed.

Long-term research impact: the case of adolescents having ‘good places to spend free time’ in Ireland

Background Demonstrating long-term impacts of research can be fraught with methodological challenges, especially when approached retrospectively. Potential accusations of bias or over-interpretation, and a lack of clear and specific causal data, can be real obstacles. This paper presents a case study of research impact, including enablers and context to aid interpretation. To develop a national set of child wellbeing indicators in line with UNCRC commitments, a participative study of children's understandings of wellbeing was undertaken to accompany a Delphi study with experts. The children contributed a number of unique indicators, including having ‘good places to spend free time'. Methods Public actions which aimed to meet Irish commitments to child wellbeing were documented. Collected evidence comprised the development of, and reporting on, a national set of wellbeing indictors for children, the development and implementation of two national policies and cyclical monitoring data, collected through the nationally representative data sets of the Health Behaviour in School-aged Children (HBSC) study in Ireland, 2002-2018. Results Measurement of stakeholder-informed indicators helped stimulate national policies on play (2004) and recreation (2007). Partnership-based policy implementation led to increases in spaces for play and recreation. Trends data from the HBSC study revealed significant and meaningful increases in ‘good places to go spend free time' for children aged 10-17 from 45.1% in 2002 to 63.5% in 2018, and for all socio-demographic sub-groups. Temporal analyses showed that increases followed policy implementation. Conclusions This impact case study links an original participative study, though policy development and implementation, to long-term improvements in Irish children reporting having ‘good places to spend free time'. An understanding of the decision-making context at key points is important to aid interpretation of the evidence under investigation. Key messages Commitment to child participation influenced national indicator adoption, policy development and implementation, with subsequent improvements to children’s health-related environments. The quality and specificity of data needed to demonstrate long-term research impact is challenging and interpretation requires contextualisation to avoid leaps of faith.

Sexual jokes at school and students’ life satisfaction: findings from the 2017/18 Swedish Health Behaviour in School-aged Children study

Objective In a previous study we demonstrated that the occurrence of sexual jokes in the class was associated with higher levels of psychological health complaints. Building on and extending these findings, the aim of the current study was to examine if exposure to sexual jokes at the student and at the class level was inversely associated with students’ life satisfaction. Data were derived from the 2017/18 Swedish Health Behaviour in School-aged Children (HBSC) study, with students aged 11, 13 and 15 years (n = 3710 distributed across 209 classes). Exposure to sexual jokes at the student level was captured by one item. Exposure to sexual jokes at the class level was calculated by aggregating this measure. The Cantril ladder was used to operationalise life satisfaction. Two-level logistic regression analyses were performed. Results Students who were exposed to sexual jokes at school were less likely to report high life satisfaction (OR 0.38, 95% CI 0.27–0.53). An inverse association was found between the class proportion of students who were exposed to sexual jokes and students’ likelihood of reporting high life satisfaction, whilst adjusting for exposure to sexual jokes at the student level (OR 0.98, 95% CI 0.97–0.9994). The findings highlight the importance of promoting a school climate without sexual harassment.

Energy Drinks Consumption Associated with Emotional and Behavioural Problems via Lack of Sleep and Skipped Breakfast among Adolescents

The aim of our study was to explore whether energy drink consumption is associated with both emotional and behavioural problems and whether this association might be mediated by amount of sleep and breakfast consumption among adolescents. The nationally representative Health Behaviour in School-aged Children (HBSC) study, realised in 2018 in Slovakia in schools, was used to acquire needed data, with the research sample of 8405 adolescents from 11 to 15 years old (mean age = 13.43; 50.9% boys) who completed the questionnaires on their own in a presence of researchers and research assistants. Emotional and behavioural problems were assessed by a Strengths and Difficulties Questionnaire, while energy drinks consumption, breakfast consumption and sleep duration was assessed by questions in line with the HBSC study protocol. Linear regression models assessed the associations between energy drinks consumption and emotional and behavioural problems. Mediation by sleep duration and breakfast consumption was assessed with parallel mediation models. Energy drink consumption was significantly associated with emotional (p < 0.001) and behavioural problems (p < 0.001), with higher consumption of energy drinks leading to more emotional and behavioural problems. Results from a parallel mediation analysis indicated that energy drink consumption is indirectly related to both emotional and behavioural problems through its relationship with the amount of sleep and breakfast consumption. Parents and professionals working with adolescents should be aware that unhealthy dietary habits and lack of sleep might be related to emotional and behavioural problems.

Chronic Backpain Among Adolescents in Denmark: Socioeconomic Inequality and Trends 1991-2018

Chronic backpain among adolescents is important because the prevalence and the burden of disability is high. Chronic backpain tracks into adulthood and is associated with several health problems. The objective was to study trends in the prevalence of chronic backpain among adolescents 1991-2018, to examine the association with socioeconomic status (SES) and whether this association changed over time. The study used data from eight comparable cross-sectional school-surveys of nationally representative samples of 11-15-year-olds in 1991, 1994, 1998, 2002, 2006, 2010, 2014 and 2018, the Danish arm of the international Health Behaviour in School-aged Children (HBSC) study. The participation rate was 88.0%, n=29,952. Chronic backpain was defined as self-reported backpain daily or several days a week during the last six months. The prevalence of chronic backpain was 11.1%, significantly increasing from 8.9% in 1991 to 11.7% in 2018. The OR for chronic backpain was 1.20 (1.10-1.31) in middle and 1.56 (1.41-1.73) in low compared to high OSC. Sensitivity analyses with two other cut-points for backpain frequency showed similar associations. Conclusion: Chronic backpain is common among adolescents and the prevalence increased from 1991 to 2918. The prevalence was highest in lower SES families. We recommend increased efforts to prevent chronic backpain.

Transport to School and Mental Well-Being of Schoolchildren in Ireland

Objectives: We explored whether modes of transport (cycling, walking, public transport or private vehicle) between home and school are associated with mental well-being in children aged 10–17 years, participating in the Irish Health Behaviour in School-aged Children (HBSC) study.Methods: Scores on the World Health Organization Well-being Index and the Mental Health Inventory five-item versions, self-reported life satisfaction, happiness with self, body satisfaction, excellent self-rated health, and multiple health complaints of 9,077 schoolchildren (mean age: 13.99 ± 1.91 years, percentage girls: 52.2%) were compared across modes of transport, unadjusted and adjusted for gender, age, family affluence and area of residence.Results: Those who reported using public transport reported poorer mental well-being than those using other means of transport, but adjusting for sociodemographic variables obscured these differences. The only exception was excellent health, where children who cycled outperformed the other three groups, even after adjustment for sociodemographic variables.Conclusions: Cycling can improve well-being in children. However, in promotion of cycling, social and environmental determinants and inequalities which influence adolescents’ and their parents’ decisions on modes of transport, need to be considered.

12-Year Trends in Active School Transport across Four European Countries—Findings from the Health Behaviour in School-Aged Children (HBSC) Study

Active school transport (AST) is a source of daily physical activity uptake. However, AST seems to have decreased worldwide over recent decades. We aimed to examine recent trends in AST and associations with gender, age, family affluence, and time to school, using data from the Health Behaviour in School-Aged Children (HBSC) study collected in 2006, 2010, 2014, and 2018 in the Czech Republic, Norway, Scotland, and Wales. Data from 88,212 students (11, 13 and 15 years old) revealed stable patterns of AST from 2006 to 2018, apart from a decrease in the Czech Republic between 2006 and 2010. For survey waves combined, walking to and from school was most common in the Czech Republic (55%) and least common in Wales (30%). Cycling was only common in Norway (22%). AST differed by gender (Scotland and Wales), by age (Norway), and by family affluence (everywhere but Norway). In the Czech Republic, family affluence was associated with change over time in AST, and the effect of travel time on AST was stronger. The findings indicate that the decrease in AST could be levelling off in the countries considered here. Differential associations with sociodemographic factors and travel time should be considered in the development of strategies for AST.

Alcohol consumption in early adolescence: Associations with sociodemographic and psychosocial factors according to gender

Introduction Early alcohol consumption can irreversible damage the adolescents’ brain and may affect their quality of life. In order to better prevent such a deleterious behaviour, knowing its determinants is needed. So far, only few studies among adolescents aged <15 years exist, of which the majority failed to include gender differences. Therefore, the aim of this study was to investigate whether gender differences in the association between alcohol use and sociodemographic and psychosocial characteristics among 10-14-year olds exist. Methods Data came from the 2018 Health Behaviour in School-Aged Children (HBSC) study conducted in French-speaking schools of Belgium. The sample analysed here comprised 4,364 10-14-year olds from the Walloon Region. Associations of the recent alcohol consumption (at least one glass during the past month) with sociodemographic and psychosocial characteristics were estimated using gender-stratified multivariable logistic regression modelling. Results Prevalence of early alcohol consumption was 14% (boys: 16%; girls: 12%). Migration status and family affluence scale (FAS) were associated with early alcohol consumption only in boys. Second-generation immigrant boys (vs. natives: OR = 0.66 [0.47–0.92]) and boys from “low” FAS families (vs. “high”: OR = 0.56 [0.32–0.98]) or “medium” FAS (vs. “high”: OR = 0.63 [0.43–0.92]) were less likely to have consumed alcohol in the past month. In both genders, alcohol consumption was positively associated with age and inversely associated with school satisfaction and family support. No association was observed with family structure, peer support and life satisfaction in the multivariable models. Conclusion Our findings showed that gender differences may exist in the determinants of alcohol consumption among young adolescents. They will contribute to the development of public health policies and actions for the most vulnerable adolescents, which should take gender differences into account.
