Aims: There is an urgent need to explore the impact of the COVID-19 pandemic on adolescent mental health and health behaviours. To date, there are no such studies on Swedish adolescents. As COVID-19 emerged in the middle of our ongoing 2-year follow-up examination of the Study of Adolescence Resilience and Stress, we had the unique opportunity to use the corona outbreak as a ‘natural experiment’ to study the impact of COVID-19 on 15-year-old adolescents in Sweden. Methods: Adolescents (baseline age 13.6±0.4 years) were recruited from schools in western Sweden (during the COVID-19 outbreak schools were kept open for those under 16 years of age). The COVID-19 pandemic reached Sweden on 31 January 2020. A total of 1316 adolescents answered the 2-year follow-up survey before (unexposed to COVID-19 pandemic, controls) and 584 after 1 February 2020 (COVID19-exposed). Data on stress, psychosomatic symptoms, happiness, relationships with parents and peers, school and health behaviours were collected. Results: Adolescents reported higher levels of stress and psychosomatic symptoms and lower levels of happiness at follow-up compared to baseline. These changes occurred to a similar extent in both the control and COVID-19-exposed groups. Likewise, the COVID-19-exposed group showed no deterioration in peer relations or relations with parents versus controls. We did not find any significant differences between groups regarding sleep duration and physical activity. Conclusions: Swedish adolescents exposed to COVID-19 during most of 2020 showed no differences in longitudinal changes in mental health, relationships with parents and peers, and health behaviours compared to those not exposed to COVID-19.
Child health is taking the back seat in development strategies. In summarising a newly released collaborative report, this paper calls for a novel conceptual model where child health takes centre stage in relation to the 2030 Agenda and the Sustainable Development Goals. It lays out five principles by which renewed effort and focus would yield the most benefit for children and adolescents. These include: redefining global child health in the post-2015 era by placing children and adolescents at the centre of the Sustainable Development Goals; striving for equity; realising the rights of the child to thrive throughout the life-course; facilitating evidence informed policy-making and implementation; and capitalising on interlinkages within the SDGs to galvanise multisectoral action. These five principles offer models that together have the potential of improving design, return and quality of global child health programs while re-energising the 2030 Agenda and the Sustainable Development Goals.
Background
Self-perceived mental health problems among adolescents has had an upward trend. Concurrently, adolescents’ physical activity (PA) has been falling whilst sedentary time (SED) has increased. There is a lack of research using accelerometer measured PA and SED to study their relationships to perceived stress and psychosomatic symptoms, both frequently observed mental health problems among adolescents. Whether coping strategies is one of the mechanisms underlying such relationship is less clear.
Methods
A total of 2283 13-year olds were enrolled in the baseline examination of the STARS (STudy of Adolescence Resilience and Stress) study in Western Sweden. Light-, moderate-, vigorous-intensity PA (LPA, MPA and VPA) and SED were measured using hip-worn ActiGraph GT3X+ accelerometer. A total of 1284 adolescents provided valid accelerometer data (at least 4 days with ≥10 h per day). PA and SED during school-time and leisure-time were analysed separately. Surveys were utilized to monitor perceived stress, psychosomatic symptoms and the use of coping strategies “shift-persist”. Logistic regression and mediation analyses were performed adjusting for gender, ethnicity, socioeconomic status and puberty development.
Results
We observed that more time spent in PA was associated with less stress in adolescents. The associations were observed for LPA (Odds ratio for LPA per 60 min: 0.557 (95% CI 0.399–0.776), VPA (Odds ratio for VPA per 15 min: 0.688 (95% CI 0.588–0.806) and MVPA (Odds ratio for MVPA per 15 min: 0.795 (95%CI 0.718–0.879) during leisure time, but not during school time. Similar associations were observed between leisure time PA and psychosomatic symptoms. The associations remained statistically significant even after adjusting for the confounders. Further, our data showed that adolescents who engaged more time in PA during leisure time were more likely to adopt the coping strategies of “shift-persist”. Mediation analysis showed that the use of “shift-persist” mediated the associations between leisure time PA and stress/psychosomatic symptoms.
Conclusions
Leisure time physical activity, irrespective of intensity, may facilitate successful coping with stress and stress-related mental health problems in adolescents.
To deliver on the 2030 Agenda and the seventeen development goals, while facing complex health challenges, we need research and education that extend across multiple scientific fields. This will enable researchers from a variety of disciplines to meet, identify research issues, apply for funding, and conduct interdisciplinary research. In addition, student involvement is key in achieving the 2030 Agenda’s global goals – and beyond. Challenges include, climate change and child health, non-peaceful societies, gender inequalities and health. The Swedish Institute for Global Health Transformation (SIGHT) was founded in 2017 at the Royal Swedish Academy of Sciences with the support of the Bill & Melinda Gates Foundation. SIGHT’s mission is to promote an interdisciplinary approach in research and education in the field of global health. In order to deliver on the commitment to global health among researchers and students in various scientific fields and at universities and colleges across Sweden, SIGHT has established SIGHT Fellows, a mentoring programme for academic researchers. In collaboration with universities, established research institutions, and other stakeholders, SIGHT Student Network holds dynamic meetings for students from a variety of disciplines and universities to contribute to delivering the UN’s sustainability goals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
