ATLANTA — Teens who text 120 times a day or more — and there seems to be a lot of them — are more likely to have had sex or used alcohol and drugs than kids who don't send as many messages, according to provocative new research.
The study's authors aren't suggesting that "hyper-texting" leads to sex, drinking or drugs, but say it's startling to see an apparent link between excessive messaging and that kind of risky behavior.
The study concludes that a significant number of teens are very susceptible to peer pressure and also have permissive or absent parents, said Dr. Scott Frank, the study's lead author.
"If parents are monitoring their kids' texting and social networking, they're probably monitoring other activities as well," said Frank, an associate professor of epidemiology and biostatistics at Case Western Reserve University School of Medicine.
Frank was scheduled to present the study Tuesday at a meeting of the American Public Health Association in Denver.
The study was done at 20 public high schools in the Cleveland area last year, and is based on confidential paper surveys of more than 4,200 students.
It found that about one in five students were hyper-texters and about one in nine are hyper-networkers — those who spend three or more hours a day on Facebook and other social networking websites.
About one in 25 fall into both categories.
Hyper-texting and hyper-networking were more common among girls, minorities, kids whose parents have less education and students from a single-mother household, the study found.
Frank's study is billed as one of the first studies to look at texting and social networking and whether they are linked to actual sexual intercourse or to other risky behaviors.
"This study demonstrates that it's a legitimate question to explore," said Douglas Gentile, who runs the Media Research Lab at Iowa State University.
