About The Study: This cross-sectional study including 426,000 children in Denmark found that body mass index (BMI) outcomes of COVID-19 pandemic–related control policies and restrictions were not exclusively observed among children with obesity, which suggests that pandemic-related mitigation policies targeting children and adolescents in all BMI categories are warranted. The findings of this study highlight differences among children of varying ages and BMI classes.
