“A study of 672 children from Rhode Island revealed that they scored shockingly low on tests designed to assess cognitive development. In the decade preceding the pandemic, the mean IQ score on standardized 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.
The study concluded that the key factor influencing these lower scores in infants is stress on the parents who face challenges in work and providing attentive childcare, leading to lack of stimulation and interaction with the children. It is unknown if the lower cognitive scores will have a long-term impact.”
Children born during the coronavirus pandemic have significantly reduced verbal, motor and overall cognitive performance compared with children born before, a US study suggests.
The first few years of a child’s life are critical to their cognitive development. But with Covid-19 triggering the closure of businesses, nurseries, schools and playgrounds, life for infants changed considerably, with parents stressed and stretched as they tried to balance work and childcare.
With limited stimulation at home and less interaction with the world outside, pandemic-era children appear to have scored shockingly low on tests designed to assess cognitive development, said lead study author Sean Deoni, associate professor of paediatrics (research) at Brown University.
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.
“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 prior to 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.
