Behavior problems, anxiety, and depression in youths were associated with these individuals participating in remote schooling during broader social lockdowns in a new study.
The systematic review, which was published in JAMA Pediatrics on Jan. 18, 2022, was based on data from 36 studies from 11 countries on mental health, physical health, and well-being in children and adolescents aged 0-18 years. The total population included 79,781 children and 18,028 parents or caregivers. The studies reflected the first wave of pandemic school closures and lockdowns from February to July 2020, with the duration of school closure ranging from 1 week to 3 months.
“There are strong theoretical reasons to suggest that school closures may have contributed to a considerable proportion of the harms identified here, particularly mental health harms, through reduction in social contacts with peers and teachers,” Russell Viner, PhD, of UCL Great Ormond St Institute of Child Health, London, and colleagues wrote in their paper.
The researchers included 9 longitudinal pre-post studies, 5 cohort studies, 21 cross-sectional studies, and 1 modeling study in their analysis. Overall, approximately one-third of the studies (36%) were considered high quality, and approximately two-thirds (64%) of the studies were published in journals. Twenty-five of the reports analyzed focused on mental health and well-being.
Schools provide not only education, but also services including meals, health care, and health supplies. Schools also serve as a safety net and source of social support for children, the researchers noted.
The losses children may have experienced during school closures occurred during a time when more than 167,000 children younger than 18 years lost a parent or caregiver to COVID-19, according to a recent report titled “Hidden Pain” by researchers at the University of Pennsylvania, Nemours Children’s Health, and the COVID Collaborative. Although not addressed in the current study, school closures would prevent bereaved children from receiving social-emotional support from friends and teachers. This crisis of loss also prompted the American Academy of Pediatrics to issue a National State of Emergency in Children’s Mental Health in October 2021.
New study results
These studies identified associations between school closures during broader lockdowns and increased emotional and behavioral problems, as well as increased restlessness and inattention. Across these studies, 18%-60% of children and adolescents scored higher than the risk thresholds for diagnoses of distress, especially depressive symptoms and anxiety.
Although two studies showed no significant association with suicide in response to school closures during lockdowns, three studies suggested increased use of screen time, two studies reported increased social media use, and six studies reported lower levels of physical activity.
Three studies of child abuse showed decreases in notifications during lockdowns, likely driven by lack of referrals from schools, the authors noted. A total of 10 studies on sleep and 5 studies on diet showed inconsistent evidence of harm during the specific period of school closures and social lockdowns.
“The contrast of rises in distress with decreases in presentations suggests that there was an escalation of unmet mental health need during lockdowns in already vulnerable children and adolescents,” the researchers wrote. “More troubling still is evidence of a reduction in the ability of the health and social care systems to protect children in many countries, as shown by the large falls in child protection referrals seen in high-quality cohort studies.”
