• The primary goal of study was to assess the relationship between obesity, according to BMI, and age in severe cases of COVID-19 symptoms.

• The study took place in Singapore and 182 patients were assessed; the data was obtained from medical records provided by the National Centre for Infectious Diseases, Singapore.

• 91 patients’ records were excluded from the study as BMI data was not included in their records.

• The study population, after removing the 91 patients, had 51 patients with <25 BMI, 29 patients with 25-30 BMI, and 7 patients with >35 BMI.

• It was found that patients who were under the age of 60 and a BMI of 25 or greater had a significant association with pneumonia that required low-flow supplemental oxygen and mechanical ventilation. 

• It was also found that a BMI of 25 or greater was associated with higher serum lactate dehydrogenase levels, an indicator of disease severity in COVID-19.

• These findings show that obesity is a significant risk factor in the development and treatment of severe cases of COVID-19 when relating it to younger patients (under 60).

• The primary goal of the study was to assess the relationship between BMI and age in COVID-19 symptomatic patients in terms of hospital admission and acute versus intensive care.

• The study took place in New York and involved 3615 individuals from across the New York academic hospital system.

• 775 individuals had a BMI of 30-34 and 595 individuals had a BMI ≥ 35. The other individuals in the study did not have a BMI that would classify them as obese (less than 30).

• The only significant differences in hospital in admission and intensive care were in individuals who were <60 years of age.

• Patients with a BMI of 30-34 were 2 times as likely to enter into acute care and 1.8 times as likely to enter intensive care compared to patients with a BMI of <30.

• Patients with a BMI of ≥ 35 were 2.2 times as likely to enter into acute care and 3.6 times as likely to enter intensive care compared to patients with a BMI of <30.

• This study demonstrated that for patients under the age of 60 with a BMI that would indicate obesity, the rate of hospital admission is much higher than individuals who are not obese.
