New research from Children’s National Hospital and the National Institutes of Health provides comprehensive insights into how COVID-19 affects children over time. The Pediatric COVID Outcomes Study examined symptom burden, behavioral health, and cardiology outcomes in hundreds of children and adolescents with and without COVID-19 infection.
Long-COVID Symptoms in Children
Researchers identified 20 symptoms more commonly reported in children who had COVID-19, including headaches, fatigue, forgetfulness, gastrointestinal issues, malaise, and respiratory issues. Symptoms varied by age, with some appearing early and others persisting or emerging months later. The study tracked these symptoms in the first 12 months after enrollment, making it the first and largest study of its kind in the U.S. to publish longitudinal data on pediatric long-COVID outcomes.
Physical and Mental Health Findings
In a research project with more than 800 youth, children who had COVID-19 reported worse global health, reduced physical and cognitive functioning, and increased fatigue, pain, and sleep disturbances. However, rates of anxiety and depression were similar between infected and uninfected children. Researchers noted that the pandemic has affected all children’s mental health broadly, not just those infected with the virus.
Cardiac Outcomes Reassuring
In reassuring news for families, a third prospective study found no evidence that COVID-19 causes long-term heart damage in children. Using advanced imaging, researchers observed no differences in cardiac function between infected and uninfected youth, and found no changes before and after infection. Children reporting seemingly cardiac symptoms such as chest pain or fatigue had normal heart function, indicating these symptoms are not linked to underlying heart dysfunction.
