Description
Summary:Summary Background Limited research has addressed the obesity–COVID‐19 severity association in paediatric patients. Objective To determine whether obesity is an independent risk factor for COVID‐19 severity in paediatric patients and whether age modifies this association. Methods SARS‐CoV‐2‐positive patients at NYU Langone Health from 1 March 2020 to 3 January 2021 aged 0–21 years with available anthropometric measurements: weight, length/height and/or body mass index (BMI). Modified log‐Poisson models were utilized for the analysis. Main outcomes were 1) hospitalization and 2) critical illness (intensive care unit [ICU] admission). Results One hundred and fifteen of four hundred and ninety‐four (23.3%) patients had obesity. Obesity was an independent risk factor for critical illness (adjusted risk ratio [ARR] 2.02, 95% CI 1.17 to 3.48). This association was modified by age, with obesity related to a greater risk for critical illness in adolescents (13–21 years) [ARR 3.09, 95% CI 1.48 to 6.47], but not in children (0–12 years). Obesity was not an independent risk factor for hospitalization for any age. Conclusion Obesity was an independent risk factor for critical illness in paediatric patients, and this association was modified by age, with obesity related to a greater risk for critical illness in adolescents, but not in children. These findings are crucial for patient risk stratification and care.
