78% Of People Hospitalized For Covid-19 Were Overweight Or Obese
In a study of adults who tested positive for COVID-19 were hospitalized, according to data on emergency department or inpatient visits at 238 U.S. hospitals from March to December, 27.8% were overweight and 50.2% were obese. In the past, the CDC has reported a link between obesity and severe illness, and hospitalization. This is most likely because obesity is often correlated with weakened immune function and decreased lung capacity, both of which can render ventilation difficult.
The CDC found that individuals with a body mass index of under 25 were at the lowest risk of hospitalization for COVID. However, the agency reports that, among those who are 65 and over, the risk of severe illness “sharply increased” as their BMIs rose.
In 2018, 42% of the U.S. population was obese. Obesity is defined as having a BMI of 30 or more, while overweight is defined as having a BMI of 25 or more. A man who is 5’10” and 175 pounds and a woman who is 5’4” and 146 pounds would both be considered overweight, as their BMIs would surpass 25. Additionally, a man and woman of those same heights would be “obese” at 210 and 175 pounds, respectively, according to the CDC’s BMI calculator.
According to the CDC, obesity is most prevalent among non-Hispanic Black adults, followed by Hispanic adults and non-Hispanic white people.
Though the study presents important findings on the link between COVID and obesity, the findings should be taken with a grain of salt. The study was limited to examining adult patients who received care at a hospital, meaning the risk estimates for severe COVID-19 might differ among all adults who contracted the virus. Furthermore, the report only looked at patients who chose to report their height and weight.
The CDC stressed the importance of vaccine prioritization, masking, and promoting proper nutrition and exercise. Additionally, the CDC urged clinicians to consider patients with high BMIs and/or obesity when making decisions regarding their healthcare.
The CDC wrote: “As clinicians develop care plans for COVID-19 patients, they should consider the risk for severe outcomes in patients with higher BMIs, especially for those with severe obesity.”
