NEW YORK - Texting while driving has become a greater hazard than drinking and driving among teenagers who acknowledge sending and reading text messages while behind the wheel of a moving vehicle.
The number of teens who are dying or being injured as a result of texting while driving has skyrocketed as mobile device technology has advanced.
Researchers at Cohen Children's Medical Center in New Hyde Park, N.Y., estimate more than 3,000 annual teen deaths nationwide from texting and 300,000 injuries.
The habit now surpasses the number of teens who drink and drive - a hazard that has been on a dramatic decline in recent years, researchers say.
An estimated 2,700 young people die each year as a result of driving under the influence of alcohol and 282,000 are treated in emergency rooms for injuries suffered in motor-vehicle crashes, according to the Centers for Disease Control and Prevention.
Dr. Andrew Adesman and a team of Cohen investigators found that between September 2010 and December 2011, an estimated 49 percent of boys between 15 and 18 admitted to texting while driving compared with 45 percent of girls.
"A person who is texting can be as impaired as a driver who is legally drunk," said Adesman, noting that a texting driver is distracted from the movement of traffic and the function of his or her own vehicle.
The new data are in sharp contrast to findings about drinking and driving among teens.
The CDC reported last fall that alcohol use among teen drivers has decreased by 54 percent since 1991.
Texting, however, has quickly grown in the last five to seven years, Adesman said.
"Fifty percent of high school students of driving age acknowledge texting while driving," said Adesman, chief of developmental and behavioral pediatrics at Cohen.
Further, he said, laws banning the practice don't work.
"When we compared states where there are no laws in effect (barring texting while operating a moving vehicle) and states where there are laws on the books, we found there was no difference in their responses," Adesman said. "Clearly, the laws are not effective."
The National Highway Traffic Safety Administration acknowledged Wednesday that distracted driving of all kinds - including the use of handheld cell phones - is a growing hazard.
Agency officials describe texting as among the worst of driver distractions because conversing by text simultaneously involves manual, visual and mental distractions.
Surveys cited by the agency suggest more than 100,000 drivers are texting at any given daylight moment, while more than 600,000 drivers are using handheld phones while operating a car.
As an expert in teen behavior, Adesman puts texting while driving in the same risk category as other hazardous activities, such as lack of seat belt use; drinking and driving; binge drinking; drug and tobacco use; unsafe sex, and tanning devices.
"We have very strong taboos against drinking and driving. Kids don't drink and drive every day. But some kids are out there texting and driving seven days a week - and they admit it," Adesman said.
His research dovetails with a recent California study, which demonstrated that it isn't just the teens who are texting but a large proportion of moms, dads and even grandparents.
That analysis of 715 adults between the ages of 30 and 64 found that nearly two-thirds admitted to using a cell phone while driving with children in the car, and one-third acknowledged texting while driving.
"When we compared states where there are no laws in effect (barring texting while operating a moving vehicle) and states where there are laws on the books, we found there was no difference. ... Clearly, the laws are not effective."
