ABSTRACT
OBJECTIVE: To test the presence of the obesity paradox in two cohorts of patients hospitalized for COVID-19. DESIGN: Two multicenter prospective cohorts. SETTING: Three fourth level institutions. PATIENTS: Adults hospitalized in the general ward for confirmed COVID-19 in the three institutions and those admitted to one of the 9 critical care units of one of the institutions. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Categorized weight and its relationship with admission to the ICU in hospitalized patients and death in the ICU. RESULT: Of 402 hospitalized patients, 30.1% were obese. Of these, 36.1% were admitted to the ICU vs. 27.1% of non-obese patients. Of the 302 ICU patients, 46.4% were obese. Of these, mortality was 45.0% vs. 52.5% for non-obese. The requirement to transfer hospitalized patients to the ICU admission get a HR of 1.47 (95%CI 0.87-2.51, pâ¯=â¯0.154) in the multivariate analysis. In intensive care patients, an HR of 0.99 (95%CI: 0.92-1.07, pâ¯=â¯0.806) was obtained to the association of obesity with mortality. CONCLUSIONS: The present study does not demonstrate an association between obesity and risk of inpatient transfer to intensive care or death of intensive care patients due to COVID-19 therefore, the presence of an obesity paradox is not confirmed.
