WASHINGTON (Reuters) - People who are obese but otherwise healthy may be at special risk of severe complications and death from the new H1N1 swine flu virus, U.S. researchers reported on Friday.
They described the cases of 10 patients at a Michigan hospital who were so ill they had to be put on ventilators. Three died. Nine of the 10 were obese, seven were severely obese, including two of the three who died.
"What this suggests is that there can be severe complications associated with this virus infection, especially in severely obese patients," said CDC virus expert Dr. Tim Uyeki.
Dr. Lena Napolitano of the University of Michigan Medical Center and colleagues studied the cases of 10 patients admitted to the university's intensive care unit with severe acute respiratory distress syndrome caused by infection with H1N1.
"Of the 10 patients, nine were obese (body mass index more than 30), including seven who were extremely obese (BMI more than 40)," they wrote in their report.
Their study was not designed to see if obesity or anything else poses a special risk factor for flu. But the researchers were surprised to see that seven of the 10 patients were extremely obese.
July 1, 2009 -- It's official, again. For the fifth year in a row, Mississippi is still the nation's heaviest state -- ground zero for obesity in the U.S.
That's according to a new report, F as in Fat 2009, issued today by the nonprofit Trust for America's Health in partnership with the Robert Wood Johnson Foundation.
The report shows that 32.5% of Mississippi adults are obese and 44.4% of kids 10-17 are overweight or obese.

I have taken a few statistics courses, and if I remember 1 thing, it is that you have to test a large sample to make a conclusion.
10 people? 300 million Americans, that's stupid. And, they would have to study people from more than 1 health care facilitiy, those 10 may have had bad treatment from bad doctors in a bad facility.
"The high prevalence of obesity in this case series is striking," the CDC's commentary accompany the report reads.
"Whether obesity is an independent risk factor for severe complications of novel influenza A (H1N1) virus infection is unknown.
Obesity has not been identified previously as a risk factor for severe complications of seasonal influenza."

I don't think anyone should be required to get the vaccine. I was just stating my opinion of what may happen because of what Reuters reported, not your post words.

The first study discovered leptin -- a hormone produced by fat cells that control how much food is eaten and how quickly energy is burned -- also supports white blood cell production, which in turn enhances immune function.
"This is a brand new role for leptin," Fraker said. "It appears that most obese people may be somewhat immunosuppressed. This finding shows us that the body's resistance to leptin plays a role in that, too."
The second study found corticosteroids produced naturally in the body do not suppress the immune system in the way prescription steroids -- such as inflammation-reducing prednisone -- do.
"With the pharmacological versions of steroids, you lose some immune function," Fraker said.
