A study in the US suggests that children born during the pandemic have significantly reduced verbal, motor and overall cognitive performance compared to children born before.
The initial years of children’s lives are crucial to their cognitive development. But due to the pandemic, the lives of children changed noticeably with the closure of playgrounds, schools and kindergartens, with parents stressed and stretched as they tried to balance work and childcare, reports The Guardian.
Associate Professor of paediatrics (research) at Brown University and lead study author Sean Deoni said, due to the limited stimulation at home and less interaction with the outside world, pandemic-era children appear to have scored shockingly low on tests designed to assess cognitive development.
In the decade preceding the pandemic, the mean IQ score on standardised tests for children aged between three months and three years of age hovered around 100, but for children born during the pandemic that number tumbled to 78, according to the analysis, which is yet to be peer-reviewed, reports the Guardian.
“It’s not subtle by any stretch,” said Deoni. “You don’t typically see things like that, outside of major cognitive disorders.”
The study included 672 children from the state of Rhode Island. Of these, 188 were born after July 2020 and 308 were
born before January 2019, while 176 were born between January 2019 and March 2020. The children included in the study were born full-term, had no developmental disabilities and were mostly white, reports the Guardian.
Those from lower socioeconomic backgrounds fared worse in the tests, the researchers found.
The biggest reason behind the falling scores is likely the lack of stimulation and interaction at home, said Deoni. “Parents are stressed and frazzled … that interaction the child would normally get has decreased substantially.”
Whether these lower cognitive scores will have a long-term impact is unclear. In the first few years of life, the foundations for cognition are laid, much like building a house – it’s easier to add rooms or flourishes when you’re building the foundation, Deoni said. “The ability to course-correct becomes smaller, the older that child gets.”
Given this data comes from a relatively affluent part of the US, where social support and unemployment benefits are generous, the fear is that things could be worse in poorer parts of the country and the world, he added.
Sir Terence Stephenson, a Nuffield professor of child health at University College London, said the research was interesting given much has been written about the impact on the education of school-age children, but not much has come out on infants, reports the Guardian.
The key factor influencing these lower scores in infants has likely been stress on parents who faced challenges in both working and providing full-time attentive childcare, he said. “Perhaps not surprising that children from lower socioeconomic families have been most affected as this resonates with many of the other financial, employment and health impacts of the pandemic.”
