Attention Deficit Linked to TV Viewing
Risk to Children Increases With Number of Hours Watched, Study Finds

CHICAGO, April 4 -- Very young children who watch television face an increased risk of attention deficit problems by school age, a study has found, suggesting that TV might overstimulate and permanently "rewire" the developing brain.

For every hour of television watched daily, two groups of children -- ages 1 and 3 -- faced a 10 percent increased risk of having attention problems at age 7.

The findings bolster previous research showing that television can shorten attention spans and support recommendations by the American Academy of Pediatrics that children younger than 2 should not watch television.

"The truth is there are lots of reasons for children not to watch television. Other studies have shown it to be associated with obesity and aggressiveness," said lead author Dimitri A. Christakis, a researcher at Children's Hospital and Regional Medical Center in Seattle.

The study, appearing in the April issue of Pediatrics, involved 1,345 children who participated in government-sponsored national health surveys. Parents answered questions about the children's TV viewing and rated their behavior at age 7 on a scale similar to measures used in diagnosing attention deficit disorders.

The researchers lacked data on whether attention deficit disorders had been diagnosed in the youngsters, but the number of children whose parents rated them as having attention problems -- 10 percent -- is similar to the prevalence in the general population, Christakis said. Problems included difficulty concentrating, acting restless and impulsive and being easily confused.

About 36 percent of the 1-year-olds watched no TV, while 37 percent watched one to two hours daily and had a 10 percent to 20 percent increased risk of attention problems. Fourteen percent watched three to four hours daily and had a 30 percent to 40 percent increased risk compared with children who watched no TV. The remainder watched at least five hours daily.

Among 3-year-olds, only 7 percent watched no TV, 44 percent watched one to two hours daily, 27 percent watched three to four hours daily, almost 11 percent watched five to six hours daily, and about 10 percent watched seven or more hours daily.

In a Pediatrics editorial, educational psychologist Jane M. Healy said the study "is important and long overdue" but needs to be followed up to better explain the mechanisms that may be involved.

Christakis said unrealistically fast-paced images typical of most TV programming may alter normal brain development.

"The newborn brain develops very rapidly during the first two to three years of life. It's really being wired" during that time, Christakis said.

Overstimulation during this critical period "can create habits of the mind that are ultimately deleterious," Christakis said. If this theory holds true, the brain changes likely are permanent, but children with attention problems can be taught to compensate, he said.

Jennifer Kotler, assistant director for research at Sesame Workshop, which produces children's programs including "Sesame Street," questioned whether the results would apply to educational programming.

"We do not ignore this research," but more is needed on variables that could affect the impact of early exposure to television, including whether content or watching TV with a parent makes a difference, Kotler said.

"There's a lot of research . . . that supports the positive benefits of educational programming," she said.
