A WaPo headline,
quoted along with substantial text from the article by my son John at Facebook, where I expressed surprise that the factor was so low and asked:
Did they count obesity as a "condition" when they did that calculation?
Then:
I looked at the CDC report, and I see it only counted "severe obesity (body mass index ≥40 kg/m2)" as a condition. I'm a 5'5" woman, and I would need to weigh more than 240 pounds — more than 100 pounds over normal weight — to enter that BMI range.
Obesity begins at a 30 BMI, which would be 180 pounds for my height. That's 60 pounds less than the weight the CDC counted as a "condition" when it did its calculation. It wouldn't be 12 times as likely but what? — 100 times? — if they'd included the merely obese. And what if they'd counted the overweight but not obese? That would go all the way down to 150 for my height. It would be useful to know, because we have some power over our own weight!
ADDED: My son questions my observation. The factor should be lower if they included less severe conditions. I agree with him. I'm thinking in terms of being less likely to die. When you're trying to figure out how dangerous the illness is to you, you consider how likely it is for a person in your condition to die if they get the disease. Perhaps it's the case that 99.9% of those who died of the disease were obese. Of course, that's not the same as saying if you get the disease and you're obese, you have a 99.9% chance of dying. But if the overall percentage of those who get the disease and die is 0.1%, then I'd like to know what's the percentage for those who get the disease but are not obese? Is it 0.01%? That would be extremely useful information! For one thing, it would give people something to do to protect themselves: lose weight. But also, it would show us who should continue the more extreme form of social distancing and who should feel free to get out and about.
