Study: Minority Kids Spend Most Waking Hours Plugged In To Media

USA Today reports:

Among 8- to 18-year-olds, Asian Americans logged the most media use (13 hours, 13 minutes a day), followed by Hispanics (13 hours), blacks (12 hours, 59 minutes), and whites (8 hours, 36 minutes.)
Researchers didn't say why, but some experts have theories.

"Children may turn to media if they feel their neighborhoods lack safe places to play or if their parents have especially demanding jobs that prevent engagement," says Frederick Zimmerman, chair of the department of Health Services at UCLA School of Public Health.

Michael Rich, professor of pediatrics at Harvard Medical School and director of the Center on Media and Child Health at Children's Hospital Boston tells USA Today that screen time may also be the culprit behind the obesity epidemic among minority kids and contribute to their sleep deprivation:

Growing obesity rates among children, especially minority youth, may also correlate to the high screen time...Rich, who blogs online at Askthemediatrician.org, says he is also concerned about the content of media being viewed, and that children are losing valuable sleep hours to electronics, which can affect school performance and behavior.
