ScienceDaily (Aug. 3, 2010) — Although the prevalence of obesity and obesity-attributable deaths has steadily increased, the resultant burden of disease associated with obesity has not been well understood. A new study published in the September issue of the American Journal of Preventive Medicine indicates that Quality-Adjusted Life Years (QALYs) lost to U.S. adults due to morbidity and mortality from obesity have more than doubled from 1993-2008 and the prevalence of obesity has increased 89.9% during the same period.
The statistics are alarming, confirming what we have known from observation of people in the United States fior the past 20 years. Between 1993 and 2008, the prevalence of obesity increased from 14.1% to 26.7%. According to the study, black women had the most quality adjusted life years lost due to obesity, at 0.0678 per person in 2008. This is 31% higher than black men, 50% higher than white women and white men.

In 2008, another study projected that nearly 80% of people in the United States may be overweight by 2030 if current trends continue (and they are).
