P03-08 Do sports and PA offer a special arena with particularly good opportunities to work with the personal development of young people? - A study of young people's personal developing opportunities on sports-based independent boarding schools in Denmark

Abstract Background Independent boarding schools are a unique Danish type of residential setting for young people between the ages of 14 to 18. Distinguishing independent boarding schools from Danish public schools is, the independent boarding schools' distinct obligation to promote the ‘personal development' of the students. Approximately half of the 242 Danish independent boarding schools have an explicit focus on sport and physical activity (PA). Thus, it is interesting to investigate if sports-based independent boarding schools offer an arena with particularly good opportunities to work with the personal development of young people? Methods In March 2019 a survey was distributed to 1020 students at three participating sports-based independent boarding schools. This survey has since been developed further and in March 2022, it will be distributed nationwide to approximately 120 schools, with the scope of reaching approximately 18.000 students. To gain insights in regard to the aim of the study, the survey will collect quantitative data on sociodemographics of the students, motives for choosing independent boarding school life, the students' perception of the pedagogical practice in sports and PA lessons, the students' perceived personal development, and the students' well-being. Results and conclusion The study will take place in March 2022 and thus data and conclusions will be presented at the conference.

Results and conclusion
The study will take place in March 2022 and thus data and conclusions will be presented at the conference. Keywords: personal development, sports, physical activity, school

Background
Poor mental health among youth is a public health concern. As half of the mental disorders occur before or during adolescence it is important to investigate how modifiable lifestyle factors are associated with mental health in this population. The association between physical activity patterns and mental health has been studied before but most studies rely on selfreported physical activity. This study aimed to investigate the associations between device-measured physical activity patterns, sports participation, screen time, and mental health in Swedish adolescents. Methods Cross-sectional data were collected from 1139 adolescents aged 13-14 in 2019. Data on physical activity patterns were collected using accelerometers for one week. Screen time and sports participation were self-reported by the students. Anxiety and health-related quality of life were assessed using a short version of the Spence Children's Anxiety Scale and Kidscreen-10. Although the effect sizes generally were small, the largest effect sizes were observed between the high/low MVPA group in boys (Cohen's d -0.51) and high/low screen time group on weekdays in girls (Cohen's d 0.59). With regards to anxiety, high moderate-to-vigorous-physical activity during leisure time on weekdays was associated with low anxiety scores in girls (B=-0.09, CI: -0.13, -0.05) and boys (B=-0.4, CI: -0.07, -0.01). Gender differences were observed, boys participating in organized sports had lower anxiety (B= -1.81 CI: -3.49, -0.13) whereas girls who reported high screen time on weekdays had high anxiety (B = 4.06, CI: 1.94, 6.18).

Conclusions
Our results could create a paradigm for future studies to decide which types of PA patterns and time domains to target P03-10 I miss a normal life. It's gone on so long': A qualitative interpretation of youth's perceptions of a third national COVID-19 lockdown on their well-being and physical activity

Background
Youth have experienced unprecedented restrictions during the COVID-19 pandemic. It is important to ascertain youth's perceptions of how the lockdown restrictions have impacted their well-being. Given the varying restrictions imposed in different countries, exploring the impact relative to the specific restrictions is imperative. This study investigated youth's views on the impact of a third national lockdown on their well-being and physical activity.
