"We have seen a dramatic decline in death due to heart disease and stroke," says researcher Donald Lloyd-Jones, MD, ScM, chair of preventive medicine at the Northwestern University Feinberg School of Medicine.
While there is reason to celebrate that progress, he says, "We have a major tsunami that is threatening us. That is the obesity epidemic, which has been with us for 25 years. We are seeing the leading edge of this tsunami that is going to reverse many of the gains we have achieved in the last 40 years."
"We need to get serious about the obesity epidemic yesterday," he tells WebMD.
The report, "Heart Disease and Stroke Statistics -- 2012 Update,” is published in Circulation: Journal of the American Heart Association.
Every year, the American Heart Association works with the CDC and the National Institutes of Health to gather the most up-to-date statistics on heart disease, stroke, and other vascular diseases and their risk factors.
The latest information:
Heart disease and stroke accounted for 32.8%, or 1 in 3, of all U.S. deaths in 2008.
Slightly more than 67% of adults are either overweight or obese.
Among children and young adults ages 2 to 19, almost 32% are overweight or obese.
Children aren't getting enough physical activity. In 2009, 29.9% of girls and 17% of boys in grades nine to 12 said they had not done 60 minutes of moderate to vigorous physical activity even one time in the previous week.
Among adults, one-third report they engage in no aerobic leisure-time physical activity.
Calorie intake is up. The average total calorie intake from 1971 to 2004 rose 22% in women and 10% in men. Women average 1,886 calories a day now, men 2,693.
