Adolescents with emotional and behavioural problems are at higher risk to become excessive or addicted Internet users: is this association moderated by gender?

BACKGROUND: The Internet offers many opportunities for adolescents to facilitate their lives. However, its everyday use may lead to excessive behaviour, including addiction. Our aim was to assess the association between emotional and behavioural problems (EBP) and level of internet use, and whether gender moderates this association. METHODS: We used data from a representative sample of 5,433 Slovak adolescents (mean age: 13.51, 48.8% boys) from the Health Behaviour in School-aged Children-study conducted in 2018, collected through online self-report questionnaires. EBP was measured by the Strengths and Difficulties Questionnaire and excessive internet use (EIU) and internet addiction (IA) by the Excessive internet use scale. We analysed using multinomial logistic regression. RESULTS: More than 25% of the adolescents reported EIU; almost 4% reported being addicted to Internet. EIU was more prevalent in girls, but IA was more prevalent in boys. Adolescents with borderline or increased levels of EBP were more likely to report EIU (odds ratio, OR/95% confidence interval, CI: 1.85/1.60-2.14; 3.16/2.67-3.75, respectively) and IA (OR/95% CI: 2.23/1.57-3.18; 4.89/3.41-7.03, respectively). Adjustment for gender, age or perceived family wealth hardly changed the findings. Moreover, gender did not modify the associations between EBP with EIU. CONCLUSION: Adolescents with higher levels of EBP are more likely to become excessive Internet users or Internet addicts. This shows a need of early identification of adolescents with EBP as they seem to be relatively vulnerable to develop EIU or IA.

How to make healthy early childhood development more likely in marginalized Roma communities: a concept mapping approach.

BACKGROUND: This study aims to assess which measures could improve the healthy early childhood development of children from marginalized Roma communities and to identify priority measures. METHODS: Concept mapping approach was used, using mixed methods. In total 54 professionals, including social workers, educators, health care providers, municipality representatives, and project managers participated in our study. RESULTS: Four distinct clusters of measures targeting living conditions, public resources, healthcare and community interventions, and 27 individual priority measures of highest urgency and feasibility were identified. The cluster 'Targeting living conditions', was rated as the most urgent but least feasible, whereas the cluster 'Targeting health care', was considered least urgent but most feasible. Among the 27 priority measures, 'Planning parenthood' and 'Scaling up existing projects' had the highest priority. CONCLUSION: Our results reflect the public and political discourse and indicate significant barriers to implementation. Reducing inequalities in early childhood needs to be addressed through coordinated efforts.

Body image, body composition and environment: do they affect adolescents' physical activity?

BACKGROUND: Most adolescents are less physically active than recommended, despite the strong effort of various stakeholders to promote physical activity (PA). Body image and body composition may play an important role not only in directly facilitating adolescents' PA but also in enabling environment-related factors. As evidence is lacking, we aimed to assess the associations of adolescents' PA with body-related and environment-related factors, whether this differs by age and gender, and whether these factors interact. METHODS: We used data on 888 11- to 15-year-old adolescents (mean age = 13.5, 56% boys) from the Health Behaviour in School-aged Children study conducted in 2018 in Slovakia. We used multinomial logistic regression analysis to assess the association of adolescents' PA with body-related factors (body image, body composition) and environment-related factors (PA-promoting environment, less leisure constraints), taking into account age and gender. RESULTS: Adolescents who perceived their body as not too fat were more likely to be physically very active rather than inactive [odds ratios (ORs)/95% confidence interval (CI) 2.15/1.44-3.22], and similarly those who were not overweight/obese (3.24/2.09-5.01) and perceived less leisure constraints (1.74/1.44-2.11). In older adolescents and in girls, the association of adolescents' PA with body composition and environment-related factors was stronger. The association of adolescents' PA with perceiving less leisure constraints was stronger among adolescents who did not perceive their body as too fat (OR/95% CI 1.98/1.26-3.14), and for those who were not overweight/obese (OR/95% CI 1.62/1.01-2.57). CONCLUSION: Adolescents' PA is associated with both body-related and environment-related factors. These associations are stronger in girls and older adolescents, if co-occurring.

Does it fit better? Measures of physical activity among adolescents in relation to health indicators.

BACKGROUND: Measuring physical activity (PA) is one of the pillars of successful health promotion; however, we struggle to find a tool enabling the identification of risk groups. The current standard approach of assessing moderate-to-vigorous physical activity (MVPA) every day does this inadequately. The aim of this study is to explore whether three other indicators of adolescents' PA can identify such risk groups in a better way. METHODS: We used data on 888 11- to 15-year-old adolescents (mean age = 13.5, 56% boys) from the Health Behaviour in School-aged Children study conducted in 2018 in Slovakia. Sufficient PA was indicated by the following four indicators: (i) MVPA every day, (ii) MVPA 5-7 days a week, (iii) engagement in organized sports (team or individual) and (iv) combining MVPA 5-7 days a week and engagement in organized sports. We used binary logistic regression analysis to assess the association of various indicators of adolescents' PA with body composition, cardiovascular fitness and self-rated health (SRH), considering age and gender. RESULTS: Being active based on various indicators was associated with better health outcomes, with the strongest associations for the indicator combining MVPA 5-7 days a week and engagement in organized sports. The only exceptions were the non-significant associations of active adolescents (being active 5-7 days per week or engaged in organized sports) with cardiovascular fitness and SRH. CONCLUSIONS: Measuring PA using an indicator that combines MVPA 5-7 days a week and engagement in organized sports is the most valid using three health indicators as criteria.

Does family communication moderate the association between adverse childhood experiences and emotional and behavioural problems?

BACKGROUND: Adverse childhood experiences (ACEs) and poor family support and communication can increase emotional and behavioural problems (EBP). Therefore, we assessed the association of difficult communication with mother and with father separately with both emotional and behavioural problems (EBP), and whether adolescents' communication with mother and with father moderates the association of adverse childhood experiences (ACE) with the EBP of adolescents. METHODS: We used data from the Health Behaviour in School-aged Children study conducted in 2018 in Slovakia, comprising 5202 adolescents aged from 11 to 15 (mean age 13.53; 49.3% boys). EBP were measured using the Strengths and Difficulties Questionnaire. We used generalized linear regression adjusted for age, gender and family affluence to explore the modification of the associations between ACE and EBP by communication (easy vs. difficult communication) with mother and father. RESULTS: Difficult communication or a complete lack of communication due to the absence of mother and father increased the probability of emotional (exp (b): 0.96, 95% CI: 0.92|1.00; and 0.95, 95% CI: 0.91|0.99, respectively) and also of behavioural problems (exp (b): 0.96, 95% CI: 0.92|1.00; and 0.94, 95% CI: 0.90|0.97, respectively). We found a statistically significant interaction of communication with father on the association of ACE with EBP, showing that the joint effects were less than multiplicative. CONCLUSION: Difficult communication with mother and father is related to EBP among adolescents, and adolescents' communication with father moderates the association of ACE with both emotional and behavioural problems among adolescents.

Adolescents exposed to discrimination: are they more prone to excessive internet use?

BACKGROUND: The Internet may serve as a suitable environment for discriminated adolescents as they may consider the online space as the place where they have possibility to build social ties they are missing in their offline life or manage their self-presentation. Therefore, our aim was to explore the association between different types of discrimination by peers (because of gender, physical appearance, culture/skin color/language, unfavorable family situation) and excessive Internet use (EIU), and whether gender moderates this association. METHODS: We used data from a representative sample of 6,462 Slovak adolescents (mean age: 13.00, 49.6% boys) from the HBSC study conducted in 2018. Data were collected through online self-reported questionnaires. We assessed the association between various types of discrimination by peers and EIU using linear regression, and the role of gender as potential moderator. RESULTS: Discrimination because of physical appearance was most prevalent (18.0%). Adolescents exposed to discrimination by peers reported higher levels of EIU. We found an interaction of gender on the association of discrimination because unfavorable family situation with EIU. Boys who experienced this type of discrimination were at higher risk of EIU compared to girls. CONCLUSION: Discriminated adolescents are more likely to use the Internet excessively, with some associations being stronger for boys than for girls. Prevention strategies focused on raising adolescent awareness of the risks and benefits of the Internet should target discriminated adolescents, especially boys, as they seem to be the vulnerable group.

Do sleeping habits mediate the association between time spent on digital devices and school problems in adolescence?

Background: This study examined the associations of Internet and computer screen time with school difficulties and the role of sleep quality and soft and energy drinks consumption. Methods: We used data from the cross-sectional Health Behaviour in School-aged Children study collected in 2014 among Slovak adolescents (aged 11.0-15.9 years, N = 7595, 48.1% boys). We examined the inter-relations between time spent with on digital devices (time spent playing digital games or Internet use), sleeping quality (sleeping shortage, sleeping difficulties), soft/energy drinks consumption and school problems (low academic achievement, disliking school, being pressured by schoolwork and truancy), using structural equation modeling. Results: Results showed that the more time adolescents spent on digital devices during leisure time, the more school problems they had. This association was mediated by a higher consumption of soft or energy drinks and a lower quality of sleeping. The direct effect of time spent on digital devices on school problems and its indirect effect via sleeping quality were relatively small (-0.26 and -0.30, respectively, standardized solution), compared with the indirect effect of time spent on digital devices via soft/energy drinks consumption as well as sleeping quality (0.65, standardized solution). Conclusions: Time spent on digital devices is associated with school problems, with sleeping and soft/energy drinks consumption playing a substantial role in this association.

Test-retest reliability of selected HBSC items measuring problem behaviour among Slovak and Czech adolescents.

OBJECTIVES: The purpose of this study was to assess the test-retest reliability of selected items based on self-reports, measuring problem behaviour in the Slovak and Czech version of the HBSC survey questionnaire. METHODS: The data from test-retest study, based on an international Health Behaviour in School-aged Children (HBSC) study and consistent with its methodology, were analysed. A sample of 580 primary school pupils (51.2% of boys), grades five and nine participated in a test and retest with a four-week interval. Six items concerning problem behaviour were evaluated overall and stratified by gender and age. RESULTS: Analyses of test-retest reliability indicated modest (0.30 to 0.49), moderate (0.50 to 0.69), or high (0.70 to 1.00) reliability across nearly all questions, with some reliability differences in analyses by gender and age. In general, findings of present study suggest the moderate reliability of measures of smoking, drunkenness, fighting and negative relationship to school, modest reliability of measures of bullying behaviour, and low reliability of measure of truancy. CONCLUSIONS: The overall findings of this study suggest that most of selected indicators in the HBSC survey questionnaire have satisfactory test-retest reliability. Further test-retest studies in a large and diverse sample, as well as validity studies, should be considered for the future HBSC study.

Regular energy drink consumption is associated with the risk of health and behavioural problems in adolescents.

Consumption of energy drinks has become popular and frequent among adolescents across Europe. Previous research showed that regular consumption of these drinks was associated with several health and behavioural problems. The aim of the present study was to determine the socio-demographic groups at risk for regular energy drink consumption and to explore the association of regular energy drinks consumption with health and behavioural problems and negative school experiences in adolescents. Data from the Health Behaviour in School-aged Children Study conducted in 2014 in Slovakia were analysed. We assessed socio-demographic characteristics, energy drink consumption, health and behavioural problems and negative school experiences based on self-reports from 8977 adolescents aged 11-15 years (mean age/standard deviation 13/1.33; 50.0% boys). The prevalence of regular energy drink consumption in the present sample was 20.6% (95%CI: 20%-21%). Regular energy drink consumption was more frequent among boys and older adolescents. Adolescents with a medium-level family affluence were less likely to drink energy drinks regularly. Adolescents who consumed energy drinks regularly had more health and behavioural problems and negative school experiences. CONCLUSION: Adolescents drinking energy drinks are at risk of a wide range of negative outcomes and should be specifically addressed by preventive interventions. What is Known • Energy drink consumption has become popular and frequent among adolescents across Europe. • There is growing evidence that energy drink consumption is related to negative social, emotional and health outcomes, but only a few studies have explored this relationship in adolescents. What is New • Regular energy drink consumption was more frequent among boys and adolescents reporting low family affluence and increased with age. • Adolescents reporting regular energy drink consumption were in higher risk to suffer from health and behavioural problems and negative school experiences.

Health-endangering everyday settings and practices in a rural segregated Roma settlement in Slovakia: A descriptive summary from an exploratory longitudinal case study.

BACKGROUND: Research into social root-causes of poor health within segregated Roma communities in Central and Eastern Europe, i.e. research into how, why and by whom high health-endangering settings and exposures are maintained here, is lacking. The aim of this study was to assess the local setup of health-endangering everyday settings and practices over the long-term in one such community. It is the initial part of a larger longitudinal study qualitatively exploring the social root-causes of poor Roma health status through the case of a particular settlement in Slovakia. METHODS: The study, spanning 10 years, comprised four methodologically distinct phases combining ethnography and applied medical-anthropological surveying. The acquired data consisted of field notes on participant observations and records of elicitations focusing on both the setup and the social root-causes of local everyday health-endangering settings and practices. To create the here-presented descriptive summary of the local setup, we performed a qualitative content analysis based on the latest World Health Organization classification of health exposures. RESULTS: Across all the examined dimensions - material circumstances, psychosocial factors, health-related behaviours, social cohesion and healthcare utilization - all the settlements' residents faced a wide range of health-endangering settings and practices. How the residents engaged in some of these exposures and how these exposures affected residents' health varied according to local social stratifications. Most of the patterns described prevailed over the 10-year period. Some local health-endangering settings and practices were praised by most inhabitants using racialized ethnic terms constructed in contrast or in direct opposition to alleged non-Roma norms and ways. CONCLUSIONS: Our summary provides a comprehensive and conveniently structured basis for grounded thinking about the intermediary social determinants of health within segregated Roma communities in Slovakia and beyond. It offers novel clues regarding how certain determinants might vary therein; how they might be contributing to health-deterioration; and how they might be causally inter-linked here. It also suggests racialized ethnically framed social counter-norms might be involved in the maintenance of analogous exposure setups.

Is risk-taking behaviour more prevalent among adolescents with learning disabilities?

Background: Reports from schools indicate that adolescents with learning disabilities (LD) frequently show risk-taking behaviour (RTB), but evidence is lacking. The aim of the study was to assess the associations between LD status and RTBs among Slovak adolescents and to explore whether family affluence and family composition have a moderating or mediating role in these associations. Data from the Slovak national HBSC study 2014 were analyzed. The sample comprised 1549 15-year-old adolescents (mean age: 15.4; 52.5% boys). RTBs were defined as early sexual experience, truancy, fighting, bullying, early smoking initiation and drunkenness. The associations between LD status and RTBs were assessed using binary logistic regression; the mediating as well as moderating role of family affluence and family composition was explored as well. Adolescents with LD are two times more likely to be engaged in early sexual experiences (OR 2.39; 95% CI 1.45-3.95), fighting (OR 1.72; 95% CI 1.01-2.95) and bullying (OR 2.08; 95% CI 1.26-3.44), but not in early smoking initiation, drunkenness or truancy. Family affluence and family composition did not moderate or mediate these associations. Adolescents with LD are at high risk of early sexual experiences, fighting and bullying but not of smoking initiation, drunkenness or truancy. Non-intact and poor families do not increase the risks associated with LD status of adolescents; however, in these families adolescents with LD are more prevalent.

Do family environment factors play a role in adolescents' involvement in organized activities?

The study assessed the association of family environment factors with adolescents' participation in organized leisure-time activities (OLTA). We used data on 10,472 Czech adolescents aged 11-15 years (49.2% boys) from the 2013/2014 Health Behaviour in School-aged Children study. The associations of family support, the presence of parental screen-time rules and joint family activities with participation in at least one OLTA were assessed using logistic regression. High family support and the presence of parental screen-time rules were associated with higher odds of OLTA participation. Moreover, adolescents playing sports, indoor games and going for walks with their families at least weekly were more likely to participate in OLTA. Conversely, those spending time in joint family TV/video watching on most days were less likely to do so. A supportive family environment and direct parental involvement in their adolescent children's leisure are associated with OLTA participation in early to middle adolescence.

Is Spiritual Well-Being Among Adolescents Associated with a Lower Level of Bullying Behaviour? The Mediating Effect of Perceived Bullying Behaviour of Peers.

The aim of this study was to explore the association between spiritual well-being and bullying among Slovak adolescents, and whether perceived bullying behaviour of peers mediated this relationship. Data from the Health Behaviour in School-aged Children study conducted in 2014 in Slovakia were used. Data were obtained from 9250 adolescents with a mean age of 13.48 years. The final sample consisted of 762 adolescents aged 15 years old (52.2% boys). We used logistic regression models and the Sobel test. Adolescents who reported a higher level of spiritual well-being were at lower risk of reporting that some or more schoolmates bully others or that they themselves bully others. These relationships were partially mediated by perceived norms about the bullying behaviour of schoolmates. Spiritual well-being was found to be negatively associated with bullying; in addition, a mediating role of perceived bullying behaviour of peers in this relationship was confirmed.

Regional mortality by socioeconomic factors in Slovakia: a comparison of 15 years of changes.

BACKGROUND: Like most Central European countries Slovakia has experienced a period of socioeconomic changes and at the same time a decline in the mortality rate. Therefore, the aim is to study socioeconomic factors that changed over time and simultaneously contributed to regional differences in mortality. METHODS: The associations between selected socioeconomic indicators and the standardised mortality rate in the population aged 20-64 years in the districts of the Slovak Republic in the periods 1997-1998 and 2012-2013 were analysed using linear regression models. RESULTS: A higher proportion of inhabitants in material need, and among males also lower income, significantly contributed to higher standardised mortality in both periods. The unemployment rate did not contribute to this prediction. Between the two periods no significant changes in regional mortality differences by the selected socioeconomic factors were found. CONCLUSIONS: Despite the fact that economic growth combined with investments of European structural funds contributed to the improvement of the socioeconomic situation in many districts of Slovakia, there are still districts which remain "poor" and which maintain regional mortality differences.

Lack of parental rule-setting on eating is associated with a wide range of adolescent unhealthy eating behaviour both for boys and girls.

BACKGROUND: Unhealthy eating habits in adolescence lead to a wide variety of health problems and disorders. The aim of this study was to assess the prevalence of absence of parental rules on eating and unhealthy eating behaviour and to explore the relationships between parental rules on eating and a wide range of unhealthy eating habits of boys and girls. We also explored the association of sociodemographic characteristics such as gender, family affluence or parental education with eating related parental rules and eating habits of adolescents. METHODS: The data on 2765 adolescents aged 13-15 years (mean age: 14.4; 50.7 % boys) from the Slovak part of the Health Behaviour in School-Aged Children (HBSC) study 2014 were assessed. The associations between eating-related parental rules and unhealthy eating patterns using logistic regression were assessed using logistic regression. RESULTS: Unhealthy eating habits occurred frequently among adolescents (range: 18.0 % reported skipping breakfast during weekends vs. 75.8 % for low vegetables intake). Of all adolescents, 20.5 % reported a lack of any parental rules on eating (breakfast not mandatory, meal in front of TV allowed, no rules about sweets and soft drinks). These adolescents were more likely to eat unhealthily, i.e. to skip breakfast on weekdays (odds ratio/95 % confidence interval: 5.33/4.15-6.84) and on weekends (2.66/2.12-3.34), to report low consumption of fruits (1.63/1.30-2.04) and vegetables (1.32/1.04-1.68), and the frequent consumption of sweets (1.59/1.30-1.94), soft drinks (1.93/1.56-2.38) and energy drinks (2.15/1.72-2.70). CONCLUSIONS: Parental rule-setting on eating is associated with eating behaviours of adolescents. Further research is needed to disentangle causality in this relationship. If causal, parents may be targeted to modify the eating habits of adolescents.

Differences between Roma and non-Roma in how social support from family and friends helps to overcome health care accessibility problems.

BACKGROUND: Roma are the most deprived ethnic minority in Slovakia, suffering from discrimination, poverty and social exclusion. Problematic access to good quality health care as result of institutional and interpersonal discrimination affects their health; therefore, factors which affect health care accessibility of Roma are of high importance for public health and policy makers. The aim of this study was to explore the association between health care accessibility problems and ethnicity and how different levels of social support from family and friends affect this association. METHODS: We used data from the cross-sectional HepaMeta study conducted in 2011 in Slovakia. The final sample comprised 452 Roma (mean age = 34.7; 35.2% men) and 403 (mean age = 33.5; 45.9% men) non-Roma respondents. RESULTS: Roma in comparison with non-Roma have a more than 3-times higher chance of reporting health care accessibility problems. Social support from family and friends significantly decreases the likelihood of reporting health care accessibility problems in both Roma and non-Roma, while the family seems to be the more important factor. CONCLUSION: The worse access to health care of Roma living in so-called settlements seems to be partially mediated by social support. Interventions should focus on Roma health mediators and community workers who can identify influential individuals who are able to change a community's fear and distrust and persuade and teach Roma to seek and appropriately use health care services.

Inequalities in mortality by socioeconomic factors and Roma ethnicity in the two biggest cities in Slovakia: a multilevel analysis.

BACKGROUND: The socioeconomic and ethnic composition of urban neighbourhoods may affect mortality, but evidence on Central European cities is lacking. The aim of this study was to assess the associations between socioeconomic and ethnic neighbourhood indicators and the mortality of individuals aged 20-64 years old in the two biggest cities of the Slovak Republic. METHODS: We obtained data on the characteristics of neighbourhoods and districts (educational level, unemployment, income and share of Roma) and on individual mortality of residents aged 20-64 years old, for the two largest cities in the Slovak Republic (Bratislava and Kosice) in the period 2003-2005. We performed multilevel Poisson regression analyses adjusted for age and gender on the individual (mortality), neighbourhood (education level and share of Roma in population) and district levels (unemployment and income). RESULTS: The proportions of Roma and of low-educated residents were associated with mortality at the neighbourhood level in both cities. Mutually adjusted, only the association with the proportion of Roma remained in the model (risk ratio 1.02; 95 % confidence interval 1.01-1.04). The area indicators - high education, income and unemployment - were not associated with mortality. CONCLUSION: The proportion of Roma is associated with early mortality in the two biggest cities in the Slovak Republic.

Is subjective perception of negative body image among adolescents associated with bullying?

UNLABELLED: Adolescents' body image dissatisfaction has an adverse effect on peer relationships. It may lead to changes in behaviour (aggressive or passive) and consequently to bullying behaviour. Our aim was to assess the association between body image dissatisfaction and involvement in bullying and whether this differs by gender. We used data from the Slovak part of the 2010 Health Behaviour in School-aged Children study. The final sample comprised 8050 adolescents aged 11 to 15 years old (mean age 13.57), less than half of whom were boys. The association between self-reported body image and involvement in bullying was determined using multinomial logistic regression. We found a significant association between body dissatisfaction and involvement in bullying. Adolescents dissatisfied with their bodies because due to feeling overweight were more likely to become passive or reactive victims. Self-reported thinness was found to be significantly associated with bully-victims only in boys. CONCLUSION: Adolescent body dissatisfaction is strongly associated with bullying behaviour. Our findings point out the importance of incorporating at schools different types of intervention programmes supporting positive self-perceptions of adolescents and reducing bullying behaviour.

Medical Professionals' Responses to a Patient Safety Incident in Healthcare.

Objectives: Patient safety incidents (PSIs) are common in healthcare. Open communication facilitated by psychological safety in healthcare could contribute to the prevention of PSIs and enhance patient safety. The aim of the study was to explore medical professionals' responses to a PSI in relation to psychological safety in Slovak healthcare. Methods: Sixteen individual semi-structured interviews with Slovak medical professionals were performed. Obtained qualitative data were transcribed verbatim and analysed using the conventional content analysis method and the consensual qualitative research method. Results: We identified eight responses to a PSI from medical professionals themselves as well as their colleagues, many of which were active and with regard to ensuring patient safety (e.g., notification), but some of them were passive and ultimately threatening patients' safety (e.g., silence). Five superiors' responses to the PSI were identified, both positive (e.g., supportive) and negative (e.g., exaggerated, sharp). Conclusion: Medical professionals' responses to a PSI are diverse, indicating a potential for enhancing psychological safety in healthcare.

Barriers and enablers for sufficient moderate-to-vigorous physical activity: The perspective of adolescents.

BACKGROUND: Interventions to improve physical activity (PA) among adolescents continue to be a public health priority. To promote PA more effectively, we need to identify the main factors contributing to (not) engagement in PA in the perspective of adolescents themselves. Thus, we explored the barriers and enablers for sufficient moderate-to-vigorous physical activity (MVPA) in adolescents from their point of view. METHODS: We used qualitative data collected as part of the international Health Behaviour in School-Aged Children study. We obtained data from 14-17 years old adolescents from the first year of Slovak high school. We conducted 11 online, semi-structured individual and group interviews with 24 participants in total (7 boys; mean age = 15.17, SD = 0.87) in Slovakia. We analysed the data using consensual qualitative research and thematic analysis. RESULTS: In the statements of adolescents, four main themes were identified regarding factors contributing to (not) engagement in PA among adolescents. 'Myself as a source' represents the importance of adolescents' own efforts, knowledge, physical predispositions and PA experience. 'How PA can be done' represents school as an opportunity for PA, and PA teachers and sports coaches as specialists who can create an enabling environment for sports. 'Others as a source' represents the social circle that can set a positive sports example and can encourage adolescent's efforts in PA. 'Factors outside' represents other factors that can inspire adolescents, e.g. by giving them a comfortable space and time to exercise, or can be a barrier to PA. CONCLUSION: The potential factors that include adolescents' perspectives can be more leveraged in designing supportive, inclusive, enjoyable, and skills-appropriate PA programmes.
