• The primary goal of study was to assess the relationship between obesity and mortality of COVID-19 patients in France.

• The study was conducted in Paris and involved 5795 patients aged 18-79 years. The patients involved in the study were those that were admitted from February 1st to April 30th, 2020.

• Patients were separated into 3 groups based on their BMI categories: normal weight, overweight, and obese.

• After 30 days, 891 deaths occurred out of the patients admitted to the Paris hospitals.

• Patients in the obese range of BMI were more likely to die - BMI of 30-35: 1.89x increased mortality rate, BMI of 35-40: 2.79x increased mortality rate, and BMI of >40: 2.55x increased mortality rate.

• The results of this study show that COVID-19 patients with obesity have double the mortality rate compared to COVID-19 patients without obesity.
