Reopening schools during the Covid pandemic significantly improved kids’ mental health, Harvard researchers said Tuesday, leading to declines in diagnoses of anxiety, depression and ADHD and a drop in related health care spending.
Analyzing the health data of more than 185,000 California schoolchildren from 24 counties, the researchers compared the students’ mental health at the pandemic’s start in March 2020, when schools closed, to when schools reopened in June 2021.
The analysis of students between the ages of five and 18 years old revealed that the benefits of schools reopening were mostly shown in girls, potentially helping to explain recent and poor academic performance among older girls.
“This was one of our most striking findings,” health economist Pelin Ozluk, one of the study’s authors, said in a statement, “underscoring how essential school-based social environments are for girls’ wellbeing.”
The study also found that the percentage of children with a mental health diagnosis increased from 2.8 percent to 3.5 percent between 2020 and 2021; however, children whose schools reopened had decreased diagnoses.

Nine months after a school reopened, a child’s likelihood of being diagnosed with a mental health condition plummeted by 43 percent compared to before schools reopened.
And health care spending associated with mental health diagnoses also fell. Non-drug medical spending decreased by 11 percent, psychiatric drug spending fell by eight percent and spending on ADHD drugs decreased by five percent.
While the study did not determine the cause of their findings, the researchers suggested that changes in social interaction, sleep, screen time, degraded diets, learning difficulties, less access to mental health services available through schools and family hardship all could have played a role.
“Our results provide solid evidence to parents, educators, and policymakers that in-person school plays a crucial role in kids’ wellbeing,” Professor Rita Hamad, another of the study’s authors, said.
“The findings offer lessons for future public health emergencies and provide insight into why mental health worsened for children during the pandemic.”

Still, the researchers noted there were several limitations to the study. The data, which incorporates 224 school districts and an equal number of boys and girls, only included children in relatively higher-income areas who had in private health insurance.
It did not take race and ethnic background into account.
The authors said that more research is needed to determine how school reopenings during the pandemic affected the mental health of marginalized groups.
The findings build on years of research showing declines in the mental health of America’s youth, including how the pandemic worsened the crisis.
