What is the effect of school closures on children?

Text updated on 2020-11-11

Between March and May 2020, schools in many countries closed down totally or partially. These closures had negative consequences for children in terms of learning, health, and psychological well-being. A health protocol based on recent knowledge on the spread of SARS-CoV-2 could help keep schools open while limiting the spread of the coronavirus.

Numerous studies have been carried out in various countries (Spain, United States, France, Italy, Malaysia, United Kingdom, etc.) to assess the consequences for children of the closure of schools in March-May 2020.

Firstly, the closure of schools has increased the risk of pupils dropping out, with an even greater risk within the priority education networks, thus tending to increase educational inequalities.

Containment has had an effect on the health of children and adolescents. It has led to a decrease in physical activity following the cessation of physical education and sports classes, the suppression of sports activities, and anincrease in the time spent in front of monitors. These factors increase the risk of overweight and obesity even in children, which is a factor in the development of many diseases and increases the risk of developing a severe form of COVID-19. See the question What is the risk of dying from COVID-19 for an infected person?

The psychological effects of confinement in children and adolescents can be observed at several levels. School is not only a place of learning; it is also a place where children and adolescents develop multiple social relationships, and social interactions are essential for cognitive development. Confinement has also increased young people's anxiety levels, affected their emotional state and led to isolating behaviours. Being constantly in the presence of parents who are themselves anxious and/or depressed increases stress in the child. Finally, the closure of schools has increased the number of cases of mistreatment, probably due to the increase in time spent at home.

How to keep schools open despite the COVID-19 pandemic?
The closure of schools at the beginning of the COVID-19 pandemic has been decided invited to reduce the spread of the SARS-CoV-2 coronavirus. Since that time, scientific and medical studies have led to a better understanding of how the coronavirus is transmitted and how to limit its spread within individuals. Health protocols that take into account this new knowledge have been developed and their implementation greatly reduces the risk of infection.

Most of the world's governments have temporarily closed educational institutions in order to contain the spread of the COVID-19 pandemic. These national closures affect hundreds of millions of students around the world. Several other countries have implemented localized closures affecting millions more learners.

A study in Malaysia of 1,054 university students showed an increase in anxiety levels during confinement. Factors contributing to increased stress were financial constraints, distance learning, and uncertainty about the future.

In Italy and Spain, the first European countries to close schools, 85.7% of parents perceived changes in their child's emotional state and behaviour during confinement. The most frequent symptoms were: attention difficulties (76.6%), boredom (52%), irritability (39%), restlessness (38.8%), nervousness (38%), feelings of isolation (31.3%), feelings of discomfort (30.4%), and worry (30.1%).

The results of this Italian study indicate that during confinement, 30% of the parents report excessive use of video and network games, 25% report changes in eating and sleeping habits, and 18% report isolation and withdrawal behaviour.

In the United Kingdom, schools closed at the end of March 2020 and only reopened in August and September. This meant that many working parents had to juggle their professional work with their childcare responsibilities such as home schooling. One study showed that many parents used the morning to work, and that the most common hours for home schooling were in the late afternoon and evening. In early April, respondents to a national survey were asked whether they agreed that home schooling strains relationships within the household, and almost half (48 per cent) strongly or somewhat agreed. Nearly one-third (30%) of parents strongly or somewhat agreed that home schooling affects their well-being, and 50% said it affects the well-being of their children.

A survey conducted in Italy among 18,147 people shows that after 3 to 4 weeks of confinement, more than 80% of individuals show symptoms of stress, post-traumatic stress disorder, and insomnia, with women and young people being more affected.

SOS Amitié, a national helpline for people in distress in France, received 1,000 more calls per day in October 2020 than in January-February 2020, before the confinement. The association deplores that "the unprecedented situation of the health crisis due to COVID-19 has generated new suffering or anxiety and, consequently, a significant increase in the number of calls."

Humans are ultra-social beings. In the course of evolution, a unique form of sociability has emerged in humans that partly explains the specificity of human cognition and morality.

Reports of intra-family violence increased by a third during the March-April 2020 lockdown in France. This violence is a risk factor for the development of mental pathologies. In France, if you are a victim or if you are aware of a situation of child abuse, you can call 119 (911 in US/Canada, 999 in UK). If you are a victim or if you are aware of a situation of violence against a woman, you can call 3919 (different in other countries).
