A study has found that teenagers who text 120 times a day are more likely to have sex and use drink and drugs.
Researchers said there was a definite link between excessive messaging and risky behaviour.
The study, which was based on confidential surveys was taken by 4,200 students at 20 high schools in Cleveland. It revealed around one in five students were hyper-texters and about one in nine were hyper-networkers – those who spent three or more hours a day on Facebook and other social networking websites. Both conditions were more common among girls.
Those who texted at least 120 times a day were nearly three-and-a-half times more likely to have had sex than their peers who didn’t text as much. Hyper-texters were also more likely to have been in a physical fight, binge drink, use illegal drugs or take medication without a prescription.
Lead author Dr Scott Frank from Case Western Reserve University in Denver, said: ‘If parents are monitoring their kids’ texting and social networking, they’re probably monitoring other activities as well.
