Elevated BMI linked to higher risk of long COVID in youth

November 1, 2024

Higher BMI in children and young adults significantly increases the risk of post-acute sequelae of SARS-CoV-2 infection (PASC). These findings highlight the need for targeted care to prevent chronic conditions in those with elevated BMI.

This retrospective cohort study of 172,136 participants was conducted at 26 U.S. children’s hospitals from March 2020 to May 2023. Eligible participants included children and young adults ages 5 to 20 years with SARS-CoV-2 infection.

Key findings: Compared with those with a healthy weight, participants with obesity had a 25.4% increased risk of PASC, while those with severe obesity had a 42.1% increased risk. Additionally, the risk of any PASC symptoms and conditions was higher among those with overweight (5%), obesity (13%), and severe obesity (18%).
