‘Based on this data, the model calculated the percentage of COVID-19 hospitalizations that could have been prevented without these four underlying conditions. Results were published in the Journal of the American Heart Association on February 25, 2021. The researchers estimated that more than 900,000 COVID-19 hospitalizations occurred through November 2020. Based on their model, 30% of these hospitalizations were attributable to obesity, 26% to hypertension, 21% to diabetes, and 12% to heart failure. These people would still have been infected with COVID-19, but likely would not have been sick enough to need hospitalization.
‘More than one of these conditions are often present in the same person. The model also estimated hospitalizations due to different combinations. The numbers weren’t simply additive. In total, 64% of the hospitalizations might have been prevented if not for the four conditions. The model suggested that COVID-19 hospitalizations due to these conditions varied by age. Older adults with diabetes, heart failure, or hypertension were more likely to be hospitalized than younger people with the same condition. However, obesity affected COVID-19 hospitalization risk similarly across age groups.’
