Mum was probably right about this: hanging out with the wrong crowd on social networks like Facebook can encourage teenagers to engage in risky behaviours like drinking and smoking.

A study released today concludes that teenagers who see friends smoking and drinking alcohol in photographs posted on Facebook and Myspace are more likely to smoke and

"Our study shows that adolescents can be influenced by their friends' online pictures to smoke or drink alcohol,'' said Thomas Valente of the University of Southern California's Keck School of Medicine and the study's principal investigator.

"To our knowledge, this is the first study to apply social network analysis methods to examine how teenagers' activities on online social networking sites influence their smoking and alcohol use.''

Valente and his team drew conclusions from a survey of 1,563 students from the El Monte Union High School District in Los Angeles County in October 2010 and April 2011.

The researchers found that the size of one's online network of friends was not a major factor associated with risky behaviour but that exposure to friends' online pictures of partying or drinking was linked to smoking and alcohol use.

Teens whose close friends did not drink alcohol were more likely to be affected by increasing exposure to risky online pictures.

"The evidence suggests that friends' online behaviours are a viable source of peer influence,'' said Grace Huang, one of the researchers.

"This is important to know, given that 95 per cent of 12 to 17-year-olds in the United States access the internet every day, and 80 per cent of those youth use online social networking sites to communicate.''

In April 2011, nearly 30 per cent of respondents had smoked and more than half had at least one drink of alcohol.

The study appears in the September 3 online edition of the Journal of Adolescent Health.
