Elevated body mass index (BMI) in children and young adults was associated with an increased risk of post-acute sequelae of SARS-CoV-2 infection (PASC), or long COVID, a large retrospective cohort study suggested.

Those with obesity had a 25.4% increased risk of long COVID (relative risk [RR] 1.25, 95% CI 1.06-1.48) and those with severe obesity had a 42.1% increased risk (RR 1.42, 95% CI 1.25-1.61) compared with children and young adults who had healthy weight, reported Yong Chen, PhD, of the University of Pennsylvania in Philadelphia, and colleagues.

"To our knowledge, this retrospective cohort study is the first and the largest to explore the association of BMI status with PASC among the pediatric population," Chen and co-authors wrote. "The findings suggest that PASC may lead to poorer long-term quality of life, affecting physical health, educational achievement, and social development; this underscores the importance of early identification, prevention, and targeted interventions to mitigate these risks."
