• 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).
