Teens who spend lots of time surfing the web, playing games and chatting with friends on smartphones and tablets may be more likely to symptoms of attention deficit hyperactivity disorder ADHD, a U.S. study suggests.




The study involved 2,587 students in 10 high schools across Los Angeles County. The students had no significant symptoms of ADHD at the study’s start. During the two years of the study, the researchers surveyed the teens and asked them about the frequency of their participation in 14 different kinds of online activities.




About half of the students said they check social media sites and text many times every day. The study found that teens who were high frequency users of seven or 14 digital media platforms were more than twice as likely to develop ADHD symptoms than teens who did not use any media platform at a high frequency rate.




ADHD symptoms include inattention, hyperactivity, restlessness or impulsivity. The disorder, which is more common in boys than girls, affects about 5% of all children in the United States. The prevalence of ADHD has been estimated at 5% worldwide, as well.
