      When one person gains weight , their close friends oftenfollow. Researchers have just

offered evidence in a study that says obesity (肥胖) appears to spread through social ties.

But the findings might also offer hope.

      If friends help make obesity acceptable , then they might also be influential in losing the

fat.The researchers note that support groups are already an effective tool in dealing with

other socially influenced problems , likealcoholism (酗酒 ) .

     The findings appeared in the New EngLand Journal of Medicine. The researchers used

information collected from 12, 000 people. It was collected between 1972 and 2003 as

part of the Framingham Heart Study.

     The information was highly detailed. There was even contact information(联络信息 )

for close friends of the people in the study.

     The researchers examined more than 40 , 000 social ties. They found a person's

chances of becoming severely overweight increased by 50% if a friend had become

obese.

     A sister or brother of a person who became obese had a 40% increased chance of

becoming obese. The risk for a wife or husband was a little less than that.

     Nicholas Christakis of Harvard Medical School was a lead researcher in the study.

He says there is a direct causal relationship (因果关系) betweena persongetting fatand

being followed in weight gain by a friend.

     The study found that the sex of the friends was also an influence. In same-sex

friendship, a person had a 71%increased risk of becoming obese. Men had a 44%

increased risk of becoming obese after weight gainin a brother. In sisters ,it was 67% .

     The researchers also considered the effect of where people lived in relation to each

other. James Fowler of the University of California,was the other lead expert. He says

a friend who lives a few hundred kilometers away has as much influence as one in the

same neighhorhood. He says the study demonstrates the need to consider that a major

part of people's health is tied to their social connections.

     Both researchers say their research shows that obesity is not just a private medical

issue , but a public health problem.
