I haven't fully woken up yet but from the CDC site, I'm seeing this:
Excessive weight is correlated with higher levels of inflammation and immune system overreactions. Both of these things can cause bad covid outcomes. It doesn't always have to be about blood pressure, diabetes, or high cholesterol. Simply having too much fat, especially visceral fat, can put people at risk for an altered immune response to covid or any other pathogen.
Most people assumed what you wrote is correct. I assumed the same. But CDC data doesn't show a particularly strong correlation.
Quoting from the article:
Among 148,494 adults who received a Covid-19 diagnosis during an emergency department or inpatient visit at 238 U.S. hospitals from March to December, 71,491 were hospitalized. Of those who were admitted, 27.8% were overweight and 50.2% were obese, according to the CDC report. Overweight is defined as having a body mass index of 25 or more, while obesity is defined as having a BMI of 30 or more.
These two numbers total
78.0%.
Yet from the
CDC:
- Percent of adults aged 20 and over with obesity: 42.5% (2017-2018)
- Percent of adults aged 20 and over with overweight, including obesity: 73.6% (2017-2018) [meaning 31.1% overweight]
I suspect weight gain is up since 2017-2018, particularly in this year of COVID, during which people are staying home. This means that the
73.6% reported by the CVC for 2017-2018 is almost certainly low. In 2020, I would not be surprised if this number is closer to
75%.
With this in mind, let's reverse the numbers and assume
25% of the population is not overweight. They still made up
22% of hospitalizations.
Those who are overweight made up (roughly)
32% of the population and accounted for
27.8% of the hospitalizations. (Note that is is about the same ratio as those who are normal weight, yet the CDC wrote "People who are overweight may also be at increased risk." The CDC data that I am quoting does not support this.)
Those who are obese made up (roughly)
43% of the population and accounted for
50.2% of the hospitalizations.
Although there is some correlation between obesity and COVID hospitalizations, it's not as strong as many expected.
More than anything,
age is the determining factor in COVID outcome. Quoting from the
CDC:
The age correlation is many times stronger than the weight correlation.
Many health issues are associated with obesity. The CDC's goal is to encourage people to live healthier lifestyles. The CDC cannot tell you to be younger, but they can encourage you to lose weight.
I respectfully suggest looking at the data behind the words to understand what is really happening.
