Sept. 10, 2007 -- Looking for the latest news on the link between extra weight and heart disease?
Here's the scoop: Overweight people are more likely than their leaner peers to have heart disease "events"?including heart attacks, even if they control their blood pressure and cholesterol.
So say scientists including Rik Bogers, PhD, of the Centre for Prevention and Health Services Research in the Netherlands.
They reviewed 21 studies that included nearly 303,000 adults in the U.S., Australia, the U.K., and Europe.
Data included participants' BMI (body mass index) and coronary heart disease "events," including fatal and nonfatal heart attacks, sudden death, and chest pain.
The studies follow-up periods ranged from about five to 35 years. During that time, participants had 18,000 heart disease "events" -- and the overweight and obese had the greatest heart risk.
The researchers compared the odds of having a coronary heart disease "event" during the follow-up period for three groups of people: those with normal BMI, those who were overweight but not obese, and those who were obese.
Compared with people with normal BMI, overweight-but-not-obese people were 32% more likely and obese people were 81% more likely to have a heart disease "event" during the follow-up period.
Those findings are already adjusted for participants' age, sex, level of physical activity, and smoking status.
Cholesterol and blood pressure didn't totally explain the results.
After adjusting for cholesterol and blood pressure, overweight-but-not-obese people were 17% more likely and obese people were 49% more likely than people with normal BMI to have a heart "event."
The findings, published today in the Archives of Internal Medicine, did not have data on participants' eating habits or family history of heart disease.
Of course, heart disease doesn't just affect people who are overweight. Heart disease is the leading killer of U.S. men and women -- and the scale doesn't tell the full story of heart health.
If you're concerned about heart risk, check in with your doctor, no matter what size you are.
