Social links may spread obesity.

A study found, after 32 years of close observation of more than 12,000 people, people may be more likely to become obese when their friends are obese.

The New York Times had very detailed information about the sociological information about the obesity epidemic in America and the social influences of close friends or mutual friends of those who are overweight.

The LA Times had more numbers and statistics about the study compared to the explanation of how the study was conducted or what the results meant.
