The Journal of the American Medical Association (JAMA) published study results yesterday confirming the link between swine flu (H1N1) and the risks associated with extra weight. Data from the study came from information reported to the California Department of Public Health between April 23 and August 11, 2009. The study confirms anecdotal data published by this writer on October 24th.

According to details of the study published in the Los Angeles Times, the study looked at hospitalizations and deaths from the swine flu in California during the dates listed above. The results of the study show that extra weight that medically qualifies as morbid obesity (Body Mass Index in excess of 40) raises the risk for hospitalization or death from swine flu to nearly the level of pregnant women. The National Heart Lung and Blood institute has an online BMI calculator.
According to the latest statistics from the Centers for Disease Control (CDC), obesity now affects around 34 percent of all American adults. The California study showed that 58% of those hospitalized for swine flu had a BMI in excess of 30. Those with a BMI in excess of 40 were responsible for 25% of hospitalizations, even though that category of obesity has only a 5% incidence rate among the American adult population.
CDC director Thomas R. Frieden emphasized that obese individuals run a higher risk for many diseases and that obesity "should be added as one of the underlying conditions" when it comes to risk factors for swine flu (H1N1). As such, those at higher risk should contact their doctor to determine if the the new swine flu vaccine should be used in conjunction with any other health conditions.
