The study found those who text at least 120 times a day are nearly three-and-a-half times more likely to have had sex than their peers who don’t text that 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.
Compared to the heavy texters, the hyper-networkers were not as likely to have had sex, but more likely to have been involved in other risky behaviors like drinking or fighting.
A Kaiser Family Foundation study found that about half of children ages 8 to 18 send text messages on a cell phone in a typical day. The texters estimated they average 118 texts per day. That study also found that only 14 percent of kids said their parents set rules limiting texting.
