How to get the most out of parental controls. Unlike previous research, this meta-analysis found overall screen time had no association with a child's performance at school. But when each type of screen time was broken down, the study found time spent on television viewing and video games was associated with poorer academic achievement.

Teen scores appeared to be worse than those of younger children when the amount of time spent watching TV went up. That makes sense, as studies have shown television viewing replaces time kids might spend studying, sleeping, talking and getting some exercise. Prior studies show excessive TV viewing reduces the ability of children to pay attention and think clearly, while increasing poor eating habits and behavioral problems.
Video games unlikely to cause real-world violence, experts say. In this study, playing video games seemed to only impact the academic composite score in teens.
Video gaming has been linked to declines in verbal memory and restorative slow-wave sleep in school-aged children, but it has also been shown to improve motor performance and spatial abilities.
In prior studies, overall time spent on any screen has been linked to poor grades at school and various unhealthy behaviors. Based on this study, the authors feel that its time science examines the role of each type of screen, in the hopes that might help focus interventions by parents and educators.
More research is definitely needed, pediatrician Dr. Jenny Radesky, lead author on the American Academy of Pediatrics guidelines on screen use by children and adolescents, wrote in an email. Screens and digital media have changed so much since then," said Radesky, who was not involved in the study. What's a parent to do? The updates on the AAP's guidelines on screen time were in response to the growing prevalence of screens in our society.
Behavior problems, nightmares , and trouble sleeping may happen after kids watch violence on screen. Older kids can be scared by violent images too. Talking with kids this age will help them, so it's important to comfort them and explain what they see to help ease fears. But it's even better to not let your kids view shows or play games that could be frightening.
TV and video games often show behaviors like drinking alcohol , doing drugs, smoking cigarettes , and having sex at a young age as cool, fun, and exciting.
When these things seem acceptable, kids and teens might be tempted to try them. That might lead to substance abuse problems, and studies show that teens who watch lots of sexual content are more likely to start sexual activity earlier.
Health experts have long linked too much screen time to obesity. When they're staring at screens, kids are inactive and tend to snack. They're also bombarded with ads that encourage them to eat unhealthy foods like potato chips and drink empty-calorie soft drinks that often become favorite snack foods. Studies show that decreasing the amount of TV kids watched led to less weight gain and lower body mass index BMI.
Replacing video game time with outdoor game time is another good way to help kids maintain a healthy weight. As a parent, you can help decrease the harmful effects of digital media. You can monitor the type of programming and limit your child's screen time. Here are some tips for setting good viewing habits:. Choose programs for your child to watch. Always plan what your child will be watching. Don't turn on a viewing device randomly. Give choices between 2 programs you think are appropriate for your child.
Limit screen time to 1 or 2 hours a day for children older than 2 years. Literally thousands of studies have looked at whether there is a link between exposure to media violence and violent behavior.
The evidence from the research is overwhelming. Children become immune to the horror of violence, gradually accept violence as a way to solve problems, imitate violence they observe on TV, and identify with characters victims or victimizers they see on TV. Research has shown that the more hours children spend watching TV, the more likely they are to display aggressive impulses and hostile feelings.
This effect has been found to apply whether the televised behavior is performed by a human or by a cartoon character. And aggressive impulses have been found to occur with girls as well as boys and with teenagers and adults as well as children.
Many parents think that since they grew up on violent cartoons and turned out alright, their children will also. But studies have found that the amount of violence has increased dramatically and the type of violence has changed. It is now more pervasive, more sinister, and more frighteningly realistic. And the effect is lasting.
Watching TV at age four was one factor found to be associated with bullying in grade school. Kids who watch more TV start smoking at an earlier age. Television viewing was a stronger influence on starting smoking than peer smoking or parental smoking. Exposure to alcohol use on TV and in music videos such as on MTV is a risk factor for increased drinking in adolescents.
Exposure to sexual content increases the likelihood that children will become sexually active earlier in life. TV is one factor in childhood obesity. Studies have shown that the more TV watched, the more likelihood of a child being overweight.
The more TV watched as a child the higher weight, serum cholesterol, poor fitness and likelihood of smoking in adults. Girls who watch a lot of TV are at increased risk of developing eating disorders. TV viewing leads to sleep problems, especially if viewed right before bedtime. Many of us have the idea that TV is relaxing. I know I did. And while we are viewing it, it is relaxing, although not as relaxing as reading a book. But studies show that a person is less relaxed after the TV is turned off than they were before it went on.
And they are less relaxed than people who completed a physical activity or a calmer activity like reading or playing cards. Brain development may be effected. Research on early brain development and TV is not clear. Many studies link early television viewing with later attention problems, such as ADHD. Other experts disagree with these results. However, most researchers agree with the American Academy of Pediatrics when they state that children aged 2 and younger should have NO screen time.
Children older than that should be limited to hours per day of nonviolent, educational programming. Research has a lot to say about television and school performance. Television viewing may replace activities that we know help with school performance, such as reading, doing homework, pursuing hobbies, and getting enough sleep. Studies have found the following:. Children who watched exclusively educational TV as preschoolers had higher grades, less aggression, and placed more value on academics than those who watched all kinds of TV.
Children who watched little television before the age of three had significantly better scores in math and reading at age six. Watching television as a child affected educational achievement at age Watching more television in childhood increased chances of dropping out of school and decreased chances of getting a college degree, even after controlling for confounding factors.
How do we help our children develop positive television viewing habits? How do we teach our children to view television as a treat or special entertainment — especially when we may not view television that way ourselves?
