    Parents complain about their teenagers' noses always in their phones. But they might want to look into their own screen time habits.

A study from the Pew Research Center was put out last week. It found that two-thirds of parents are worried about the amount of time their teenage children spend in front of screens. But more than a third of parents said they have worries about their own screen time.

More than half of teens said they often or sometimes find their parents to be distracted(分心的).It's often when the teens are trying to have a conversation with them. The study calls teens' relationship with their phones "closely connected" at times. It shows that nearly three-fourths check messages when they wake up. They also check their notifications(通知).Parents do the same. But parents do it at a lower rate. That rate is 57 percent. It is still a lot.

Big tech companies face a growing backlash(强烈抵制).There are complaints against the nature of their products. And against their apps. People complain about the endless notifications and other features. They say they are created to keep people tied to their screens.

Many teens are trying to do something about it. Fifty-two percent said they have cut back on the time they spend on their phones. Fifty-seven percent did the same with social media.

Researchers say parents have a big role in their kids' screen habits. Setting a good example is a big part of it.

"Kids don't always do what we say but they do as we do." That's according to Donald Shifrin, a professor who works at the University of Washington School of Medicine. He was not doing the Pew study. "Parents are the door that kids will walk through on their way to the world."
