Now it looks like that link between friends and better health is true for the major online social network, too: Facebook. Researchers compared the health records of 12 million Facebook users to nonusers, in California.After controlling for things like age, race, and gender, they found that being on Facebook was associated with a slightly lower risk of death in a given year.Now, some of that could be explained by the fact that Facebook users might be more affluent, or have better access to healthcare.So the researchers did a second analysis- by looking only at Facebook and nonFacebook users on the California voter rolls,which is a sort of proxy control for socioeconomic status. And the association still held up.The study is in the Proceedings of the National Academy of Sciences. Of course correlation does not equal causation.
