Violent TV, Video Game Viewing Linked to Gene

Monday, February 24th, 2014

Children who engage in a lot of violent video game play and television viewing may be driven by genetics, according to new research conducted with Dutch children and published in the Journal of Communication.

The parents noted how much violent TV programming their children, aged 5-9, viewed, as well as how often they played violent video games. DNA samples collected at the children’s birth were then analyzed to determine whether they have a certain gene variant. The researchers found that children who had the specific variation of the serotonin-transporter gene on average consumed more violent media and displayed more ADHD-related behavior than those who did not have the genetic marker.

The researchers noted that the link is subtle, and other factors, chiefly the parenting environment children are growing up in, may be at play.  However, other research has found links between genetic factors and the overall amount of media children are likely to consume.  And this new study is the first to isolate the type of media–violent content–being consumed in light of genetic factors.  So the scientists called for further research.

“Our results indicate that children’s violent media use is partly influenced by genetic factors. This could mean that children with this gene variant are more likely to seek out stimulating activities, such as violent television viewing and video game playing,” said [researcher Sanne] Nikkelen in a statement. “It is important to study the relationship between media use and ADHD-related behaviors because children who show increased ADHD-related behaviors often face peer and academic difficulties and are at increased risk for substance abuse. Examining factors that may contribute to the development of these behaviors is essential.”

Study: Too Much TV Has Health Risks

Wednesday, June 15th, 2011

Kid Watching TelevisionA new study published this week in the Journal of the American Medical Association associates prolonged television viewing with increased risks of type 2 diabetes and cardiovascular disease, joining smoking and lack of exercise as major risk factors for those diseases.  Parents can take note of the findings in light of the American Academy of Pediatrics’ recommendation that kids under 2 watch no television, and older kids watch no more than 1-2 hours each day.

Dr. Frank Hu, a professor of nutrition and epidemiology at the Harvard School of Public Health and the study’s co-author, told The Boston Globe that the average American spends 5 hours a day watching television, possibly putting their health at risk in the process:

“There’s something unique about TV watching,” says Hu, that sets it apart from other sedentary activities, like reading a book or tapping out e-mails to friends. “People tend to eat while watching TV,” he says. “They see commercials for junk food and sugary beverages, and it’s part of our culture to eat chips and beer when watching a sporting event….It’s almost completely passive and is probably the best marker of a sedentary lifestyle — the couch potato syndrome.”
