Background: The objective of this study was to determine the associations between heart disease, obesity, and demographic factors and increased COVID-19 mortality.

Methods: We extracted deidentified patient-level data from the Froedtert Health System and Children’s Hospital of Wisconsin and used descriptive statistics and multivariable logistic regression to characterize relationships between heart disease, obesity, age group, sex, race and ethnicity and mortality following COVID-19 diagnosis.

Results: We found heart disease (adjusted odds ratio [AOR] 2.85; 95% CI, 2.11-8.83) and other demographic factors are significant predictors of increased mortality in COVID-19 patients. However, obesity was not a significant predictor of mortality (AOR 1.04; 95% CI, 0.53- 3.10).

Discussion: These unique results indicate some comorbid conditions and patient demographics contribute more strongly to mortality in COVID-19 patients.
