Background & AimVerify the prevalence of hypovitaminosis D and obesity in elderly patients infected by new coronavirus. The patients developed severe symptoms and were admitted in intensive care unit (ICU) to receive invasive ventilation due to diagnosis of acute respiratory distress syndrome (ARDS).MethodsA cross-sectional descriptive study composed of elderly (age ≥ 60 years) admitted to the ICU. Were collected demographic (sex, age), anthropometric data, presence of comorbidities (hypertension, diabetes, heart disease, lung, neurological and oncological diseases), severity score in ICU (SAPS III), PaO2/FiO2 ratio, analysis of C-reactive protein (CRP) and serum dosage of 25-hydroxy vitamin D (25 OHD) in the first day of hospitalization to identify elderly with hypovitaminosis D (low values < 30 ng/mL). The diagnosis of obesity in elderly was determined by calculating the body mass index (BMI) ≥ 30 kg/m2.ResultsA total of 176 elderly met the inclusion criteria. 54% were elderly men and mean age of 72.9 ± 9.1 years. The median BMI was 30.5 (28.1-33) kg/m2 with 68.7% having a nutritional diagnosis of obesity and 15.3% had BMI ≥ 35 kg/m2. The most prevalent comorbidities were hypertension (72.2%) and diabetes (40.9%). Prevalence of hypovitaminosis D with values of 25 OHD <30 ng/mL, < 20 ng/mL and <10 ng/mL was 93.8%, 65.9% and 21% respectively. The prevalence of hypovitaminosis D (<30 ng/mL) in obese elderly was 94.2%. There was a negative and significant bivariate correlation between BMI and levels of 25 OHD (r = - 0.15; p = 0.04).ConclusionHypovitaminosis D and obesity in elderly have a high prevalence in critically ill patients in ICU infected by the new coronavirus. Laboratory investigation of vitamin D becomes important, especially in obese elderly patients.Copyright © 2020 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.
