School-based intervention to improve mental health, cognitive function, and academic performance in adolescents
The trial was retrospectively registered on April 27, 2021. ISRCTN78666212
Stakeholders’ perspectives on barriers and facilitators to implementing extra physical activity in secondary schools to improve adolescents' health and academic performance
Introduction There is an association between physical activity and both health and academic performance. However, there is still a lack of consensus on how to engage adolescents in physical activity interventions in secondary schools. One approach to better understand the activities and strategies supporting effective implementation is to involve school staff and adolescents in the early stages of planning and preparing for interventions. Therefo…
Matrices of (dis)advantage – school segregation and social inequities in adolescent physical activity from an intersectionality approach
Tackling inequities and inequalities related to adolescents’ engagement in physical activity and sport is highlighted in recent research. However, rarely addressed are the issues of intersecting hierarchal systems of power that interlocks on both micro and macro levels, affecting how physical activity patterns express social memberships across several contexts. Therefore, this study aimed to explore how adolescents’ physical activity during leisu…
Short, frequent physical activity breaks improve working memory while preserving cerebral blood flow in adolescents during prolonged sitting - AbbaH teen, a randomized crossover trial
Retrospectively registered on 21/09/2020, ClinicalTrial (NCT04552626)
Gendered relations? Associations between Swedish parents, siblings, and adolescents' time spent sedentary and physically active
IntroductionThe family is assumed to be fundamental in youth socialization processes and development, connected to social and cultural practices such as healthy lifestyles and physical activity. However, gender patterns in physical activity among adolescents and the structural drivers of gender inequality (e.g., parentage and siblingship) are poorly understood. The aim of this study was to explore further how gender structures relate to adolescen…
Covid-19 and unfavorable changes in mental health unrelated to changes in physical activity, sedentary time, and health behaviors among Swedish adolescents
Background The COVID-19 pandemic has had major impact on the daily lives of adolescents. This study examined whether mental health outcomes had changed over the pandemic, and if such changes were related to changes in physical activity (PA), sedentary time, sleep, screen time, and participation in organized sports. Materials and methods In this longitudinal study, data were collected in autumn 2019 with follow-up measurements in spring 2021. In t…
Covid-19 induced changes in physical activity patterns, screen time and sleep among Swedish adolescents - a cohort study
Although no significant (α = 0.05) changes were seen in MVPA, both LiPA and sedentary time as well as sleep and screen time changed in unfavourable ways. More intense activities are often organised and seem to have withstood the pandemic, while less intense activities decreased. Some groups were more vulnerable and will need directed intervention in the post-pandemic period as well as when future pandemics hit
Adolescents’ experiences of a school-based health promotion intervention in socioeconomically advantaged and disadvantaged areas in Sweden
Socioeconomic factors influence participants' possibilities to engage in the intervention activities as well as how they use their time in the activities. This study showed that it is crucial to support adolescents' participation in physical activities by providing structure and engaging well-known teachers in the activities, especially in schools located in disadvantaged areas
Associations between Physical Activity Patterns, Screen Time and Cardiovascular Fitness Levels in Swedish Adolescents
Cardiovascular fitness (CVF) has been associated with cardiovascular risk factors in adolescents. CVF levels are determined by non-modifiable and modifiable factors; one modifiable factor is physical activity (PA). There is a lack of studies investigating the associations between PA patterns and CVF and how gender, parental education, BMI status and country of birth are associated with CVF. The aim of this study was to explore the cross-sectional…
Associations between the School Environment and Physical Activity Pattern during School Time in Swedish Adolescents
Knowledge about associations between school-based initiatives and physical activity patterns is limited. The purpose of this paper was to examine associations between factors in the school environment, physical activity and sedentary time during school time. The cross-sectional study included 1139 adolescents aged 13-14 from 34 schools. Physical activity and sedentary time were measured using hip-worn accelerometers. Factors in the school environ…
Adverse outcomes of chronic widespread pain and common mental disorders in individuals with sickness absence – a prospective study of Swedish twins
CMDs was a risk factor for DP, unemployment and mortality among individuals with SA, while CWP seems to be important in relation to future DP and mortality. Familial factors played a role in the associations between CMDs and DP and CMDs and unemployment
Impact of Expectations on the Effects of Exercise on Psychological Distress
The results encourage systematic use of exercise in prevention and rehabilitation of persons suffering from psychological distress. People's personal expectations might not be needed for treatment effect
Gendered relations? Associations between Swedish parents, siblings, and adolescents' time spent sedentary and physically active
