RESEARCH DESIGN AND METHODS Data were collected from 287 consecutive COVID-19 patients hospitalized at two hospitals in New Orleans, Louisiana from March 30th to April 5th, 2020. MetS was identified per WHO criteria.
RESULTS Among 287 patients (mean age, 61.5 years; female, 56.8%; non-Hispanic Black, 85.4%), MetS was present in 188 (66%). MetS was significantly associated with mortality (adjusted odds ratio [aOR]: 3.42, 95% confidence interval [CI]: 1.52-7.69), ICU (aOR: 4.59, CI: 2.53-8.32), invasive mechanical ventilation (IMV) (aOR: 4.71, CI: 2.50-8.87) and acute respiratory distress syndrome (ARDS) (aOR: 4.70, CI: 2.25-9.82), compared with non-MetS. Multivariable analyses of hypertension, obesity and diabetes individually showed no association with mortality. Obesity was associated with ICU (aOR, 2.18, CI, 1.25-3.81), ARDS (aOR, 2.44, CI, 1.28-4.65), and IMV (aOR, 2.36, CI, 1.33-4.21). Diabetes was associated with ICU (aOR, 2.22, CI, 1.24-3.98) and IMV (aOR, 2.12, CI, 1.16-3.89). Hypertension was not significantly associated with any outcome. Inflammatory biomarkers associated with MetS, C-reactive protein (CRP) and lactate dehydrogenase (LDH) were associated with mortality [CRP (aOR, 3.66, CI, 1.22-10.97), LDH (aOR, 3.49, CI, 1.78-6.83)].
CONCLUSIONS In predominantly Black patients hospitalized for COVID-19, the clustering of hypertension, obesity and diabetes as MetS increased the odds of mortality compared to these comorbidities individually.
