Obesity in COVID-19 Patients by Geographic Location

In populations with a high prevalence of obesity, such as the United States, COVID-19 will affect younger populations more than reported in other countries with lower prevalences of obesity. For example, in a large study of COVID-19 ICU patients in Italy, the median age was 63 years, with only 13% of patients younger than 51 years old and a prevalence of obesity of only 20% compared to the US' 40%.



Implications of Obesity in Patients with COVID-19

Association of Obesity and Age with severe cases of COVID-19

- Obesity prolongs the hospital stay in patients affected by COVID-19, and may impact on SARS-COV-2 shedding

Association of Obesity and Hospital Stay Length

- Risk of infection
- Effects by geographical location
- Proposed disease mechanisms that contribute to morbidity and mortality
- COVID-19 complications and outcomes

Focuses of Obesity in COVID-19 Patients

Metabolic characteristics of obese patients include higher levels of proinflammatory cytokines. Additionally, blood plasma levels of cytokines are higher in COVID-19 patients compared to healthy individuals. Due to these combined risk factors, obese patients infected with SARS-CoV-2 have a higher risk of hypercytokinemia where there is an influx of cytokines in the blood within a short amount of time; thus, leading to organ failure, severe lung damage, and significantly increased likelihood of death.
