The association of admission random blood glucose concentration and body-mass index with mortality in COVID-19 patients.

Abstract

This study aimed to investigate the association between hyperglycemia and body mass index (BMI), along with other associated comorbidities in hospitalized COVID-19 patients among the Indonesian population. This was a retrospective study conducted at Hasan Sadikin Hospital, Bandung between March 1, 2020, and August 30, 2020. Data were analyzed using the chi-square test for categorical data and unpaired t-test and Mann-Whitney alternative test for numerical data using SPSS version 24.0 (IBM SPSS Statistics for Windows, Version 24.0. IBM, Armonk, NY, USA) and GraphPad Prism version 7.0 for Windows. A total of 142 hospitalized COVID-19 patients were documented between March and August 2020 at the Hasan Sadikin Hospital. Among the 142 patients, 116 (81.7%) survived, while 26 (18.3%) died. Sex, age, BMI, number of comorbidities, heart rate, respiratory rate, peripheral oxygen saturation, platelet count, random blood glucose (RBG), and length of stay (LOS) were significantly associated with mortality. Multivariate analyses demonstrated that admission RBG levels > 140 mg/dl were independently associated with an increased risk of mortality in COVID-19 patients (OR 4.3, 95% CI 1.1-17.5, p = 0.043), while BMI > 25 kg/m2 was significantly associated with reduced mortality (OR, 0.22; 95% CI 0.05-0.88, p = 0.033). Admission hyperglycemia, indicated by an increase in RBG levels >140 mg/dL, is independently associated with an increased risk of mortality in hospitalized COVID-19 patients, while obesity (BMI >25 kg/m2) might have protective properties against the risk of death.
