The fact that too much TV can result in attention problems is well known but least supported by data. To delve deep into the issue Landhuis and his colleagues investigated 1,037 girls and boys born in 1972 and 1973, tracking them from age 5 to 15.
Normally kids were watching 3.13 hours of TV on an average weekday when they are in the age 13 to 15 and about 2 hours of TV daily when they were 5 to 11 years old.
AdvertisementStudy participants who had watched more than 2 hours of TV in early childhood were more likely to have attention problems as young teens, the researchers found. Those who watched more than 3 hours were at even greater risk.
The researchers used statistical techniques to control for the effects of attention problems in early childhood and other factors that could influence both TV watching and later attention difficulties. They found that TV watching, both in early childhood and in adolescence, independently influenced the risk of these problems in adolescence.
