Social connectedness, sleep, physical activity contribute to better mental health among teens during COVID-19 pandemic: Study

Bethesda (Maryland) [US], February 1 (ANI): While the pandemic has affected everyone, physically and mentally, equally, it has had a permanent impact on young children and adolescents, who had to stay shut indoors and miss out on so much of school life. A recent study, however, has some good news.
The research, published in the 'Journal of Adolescent Health', had a longitudinal survey data of more than 3,000 adolescents ages 11-14 recorded before and during the early months of the COVID-19 pandemic in 2020.
The survey found that supportive relationships with family and friends and healthy behaviours, like engaging in physical activity and better sleep, appeared to shield against the harmful effects of the pandemic on adolescents' mental health.
The research is based on data from the Adolescent Brain Cognitive Development (ABCD) Study, the largest long-term study of brain development and child health ever conducted in the United States.
Researchers also explored predictors of perceived stress, anxiety, and depressive symptoms, and found that girls were more likely than boys to experience psychological distress during the pandemic. Psychosocial factors, including poorer quality and functioning of family relationships, more screen time, and witnessing discrimination in relation to the pandemic, also predicted youth distress.
"Early adolescence is a time when youth are already experiencing rapid change physically, emotionally, and socially, and the COVID-19 pandemic has caused immense disruption to this sensitive stage in life," said Nora D. Volkow, M.D., director of NIDA.
"This study helps us understand how modifiable lifestyle factors affect the mental health and well-being of adolescents, and it can inform the development of interventions to protect youth during a major life stress. This is important now, as we continue to grapple with the pandemic, and also in future crisis response at the local or national level."
In this study, investigators analyzed data from a longitudinal cohort of over 3,000 ABCD Study participants ages 11 to 14-years-old and their families. These young adolescents and their parents completed pre-pandemic assessments by February 2020, which documented baseline parent/caregiver reports of externalizing problems (e.g., acting aggressively, breaking rules) and sleep disturbances (e.g., sleep duration), and youth reports of internalizing problems (e.g., feeling anxious or depressed).
Participating parents and youth then separately completed three online COVID-19 surveys, conducted between May and August 2020, which featured more than 200 items across psychosocial and lifestyle domains.
Researchers used machine learning methods to look for patterns of positive affect, anxiety, stress, and depressive symptoms across the surveys. They then interpreted the results through an algorithm to provide an overall ranking of variables according to their importance for predicting youth mental health outcomes.
The top variables were categorized into eight domains: demographics; coping behaviours (e.g., having a regular mealtime); physical activities; relationships; resources (e.g., unable to afford food), screen time, sleep (e.g., pre-pandemic sleep disturbances), and other (e.g., pre-pandemic psychological problems).
Out of all the possible predictors considered, positive relationship variables, such as talking about plans for the coming day with parents, participating in family activities, and those related to healthy behaviours like physical activities and better sleep were among the top predictors of high positive affect and were also protective against stress, anxiety, and depression.
Conversely, more screen time activities, including social media and video games, as well as witnessing racism or discrimination in relation to the coronavirus, emerged as important predictors for negative affect. The study also found that girls, and those who entered the pandemic with existing mental health or sleep problems, appeared to be particularly vulnerable to the negative impact of the COVID-19 pandemic.
"Focusing on what you can do to support young people, like maintaining as much of a routine as possible, walking at least 10 minutes a day, and strengthening family relationships, really matters during times of stress." said Fiona C. Baker, Ph.D., director of the Center for Health Sciences at SRI International, Menlo Park, California, and principal investigator of the ABCD study site at SRI.
The authors also note that compared to the full ABCD Study sample of about 11,800 people at study entry, this study included only a subsample of 3,000 youth with sufficient data from the pre-pandemic ABCD assessments and COVID-19 surveys. Compared to the full ABCD Study, this subsample of youth was less likely to be Hispanic/Latino (16 per cent vs. 20 per cent), less likely to be Black (7 per cent vs. 15 per cent), more likely to be Asian (5 per cent vs. 4 per cent), and their parents were more likely to have higher education (e.g., having a postgraduate degree 42 per cent vs. 34 per cent). Generalizability of this study is therefore limited by the fact that the sample is not representative of the U.S. population.
"This additional COVID data collection is also a valuable example of how the ABCD study team was able to effectively pivot within such a massive project, to leverage this important learning opportunity during the pandemic," said Orsolya Kiss, Ph.D., a postdoctoral fellow at SRI International and lead author of the study. "Further, machine learning techniques allowed the data itself to drive the findings, rather than expectations or hypotheses. While the team informed the structure of what data was incorporated from before and during the pandemic, the model then determined what was important." (ANI)
