Association between Obesity and Length of COVID-19 Hospitalization: Unexpected Insights from the American Heart Association National COVID-19 Registry.
Association between Obesity and Length of COVID-19 Hospitalization: Unexpected Insights from the American Heart Association National COVID-19 Registry. Journal of obesity & metabolic syndrome Collins, W. J., Chang, A. Y., Weng, Y., Dahlen, A., O'Brien, C. G., Hom, J., Ahuja, N., Rodriguez, F., Rohatgi, N. 2022Abstract
Background: Observational analyses have noted an association between obesity and poor clinical outcome from Coronavirus Disease 2019 (COVID-19). The mechanism for this finding remains unclear.Methods: We analyzed data from 22,915 COVID-19 patients hospitalized in non-intensive care units using the American Heart Association National COVID Registry of adult COVID-19 admissions from March 2020 to April 2021. A multivariable Poisson model adjusted for age, sex, medical history, admission respiratory status, hospitalization characteristics, and select laboratory findings was used to calculate length of stay (LOS) as a function of body mass index (BMI) category. Additionally, 5,327 patients admitted to intensive care units were similarly analyzed for comparison.Results: Relative to normal BMI subjects, overweight, class I obese, and class II obese patients had approximately half-day reductions in LOS (-0.469 days, P<0.01; -0.480 days, P<0.01; -0.578 days, P<0.01, respectively).Conclusion: The model identified a dose-dependent, inverse relationship between BMI category and LOS for COVID-19, which was not seen when the model was applied to critically ill patients.
