Swine Flu Kills Obese People Disproportionately
Philip K Dickhead writes "Bloomberg is reporting that the World Health Organization discovered a single, surprising characteristic that's emerged among swine flu victims who become severely ill: They are all fat. Infected people with a body mass index greater than 40 suffer respiratory complications that are harder to treat and can be fatal. The virus appears to be on a collision course with the obesity epidemic. WHO officials are gathering statistics to confirm and understand this development. 'It's very likely that if we went back retrospectively and looked at people who did poorly during seasonal flu, what would shake out is that obesity would be one of the risks.' Fat cells secrete chemicals that cause chronic, low-level inflammation that can hamper the body's immune response and narrow the airways, says Tim Armstrong, a doctor working in the WHO's chronic diseases department in Geneva."
Being obese is pretty much an invitation for all sorts of problems. I love my steak, fries, chocolate, soda and burgers, I just eat them once every other week in small quantities. It helps when I think of baby carrots and apples as snacks.
Actually in this case it's a perfectly valid way of looking at it. BMI was created for statistical analysis. And that's what it's being used for.
With the relatively small number of people that have died as a result of the H1N1 it's much easier to detect whether or not it's accurate for the group. But when doing models of how this is likely to shape out, the BMI is a perfectly legitimate way of doing it. The only other measure that's reasonable to consider is the waste to hip ratio, and that's not really designed for this.
