Social Network Influences Alcohol Use

Behavior of friends makes a huge impact, for better or worse.

The researchers found that people were 50% more likely to drink heavily if a person they were directly connected to drank heavily.

The size of the effect was 36% for those at two degrees of separation, such as a friend of a friend, and 15% for those at three degrees of separation, they added.

It disappeared at four degrees of separation.

Christakis and colleagues also found that people were 29% more likely to abstain from drinking if someone they're directly connected to abstained.

That effect size was 21% at two degrees of separation and 5% at three degrees, and disappeared at four, they said.

They also found over the course of the study that those who were surrounded by heavy drinkers increased their alcohol consumption by about 70% compared with those who weren't connected to any heavy drinkers.

Conversely, those surrounded by nondrinkers decreased their alcohol consumption by half.

In multivariate analyses, the researchers found that for every additional connection one made to a heavy drinker, the risk of drinking heavily increased by 18% (95% CI 11% to 25%, P<0.001), and it decreased the likelihood that he or she would abstain by 7% (95% CI 2% to 12%, P=0.009). On the other hand, each additional abstainer in a person's life significantly reduced the likelihood that he or she would drink heavily by 10% (95% CI 4% to 15%, P=0.001). Effects on drinking were also dependent on the relationship. Heavy drinking by a wife, for example, increased the husband's likelihood of drinking heavily by 196%, while heavy drinking by a husband increased a wife's chances for drinking heavily by 126%.
