WASHINGTON, D.C. -- Distracted walking is becoming a dangerous, even deadly problem.
People who text or use cell phones or other electronics while walking are stumbling into danger: walking into traffic, falling off curbs, and walking in front of trains.
Nearly 1,200 people were treated in emergency rooms across the country last year for injuries sustained while walking and using a cellphone or another electronic device, according to the Consumer Product Safety Commission.
That's just the number of people who admitted to being distracted while walking.
CPSC analysts believe there are many more people who don't tell the ER doctor, and many doctors who don't include it in their reports.
A study from the University of Maryland found 116 cases where pedestrians were killed or seriously injured while wearing headphones over the past six years.
Two-thirds of the victims were men under 30.
Half the cases involved trains.
