Wondering why your waistline is expanding? Have a look at those of your friends. Your close friends can influence your weight even more than genes or your family members, according to new research appearing in the July 26 issue of The New England Journal of Medicine. The study's authors suggest that obesity isn't just spreading; rather, it may be contagious between people, like a common cold. Originally published on July 25, 2007.

Tonight's story focuses on a report from the Framingham Heart Study that suggests that obesity – and thinness – can spread through social ties. And it's not just that obese people tend to hang out together. If one of a pair of mutual friends BECOMES obese (defined as Body Mass Index, or BMI>= 30) then the risk of the other becoming obese increases by 171%! And social closeness is much more important than geographic closeness. There was no effect for next door neighbors who weren't friends. But a friend 1,000 miles away influences you as much as a friend next door. Originally published on July 25, 2007.
