Visceral to subcutaneous fat ratio predicts short-term mortality in patients with Covid 19. A multicenter study.

Objective: To evaluate the association of body composition parameters with outcomes in Covid-19.

Methods: 173 patients hospitalized for Covid-19 infection in 6 European centers were included in this retrospective study. Measurements were performed at L3-level and comprised skeletal muscle index (SMI), muscle density (MD), and adipose tissue measurements [visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), intramuscular adipose tissue (IMAT), visceral-to-subcutaneous-adipose-tissue-area-ratio (VSR)].
