Impacts of TV on School-Age Children: What Research Shows the Misconception and Real Negative Impacts

Based on the results of 10 studies, there are 5 problems and 1 mis-conception about the negative impacts of TV-viewing for children.

The problems: TV-viewing is strongly related to obesity, particularly for children who spend less time doing physical activities. It is also associated with short-term aggressive behavior, especially among boys, and is associated with attention problems. More TV-viewing is associated with decreased academic achievement among elementary school children, particularly when watching TV on weekdays. For adolescents, watching TV more than 10 hours per week is associated with decreased academic achievement. One study found that childhood TV-viewing at ages of 5-11 is related to attention problems at ages 13 and 15. 

There is a misconception that TV-viewing is related to myopia. However, based on 2 studies, as long as they don’t sit too close to the screen, TV-viewing is NOT related to myopia, even for children who watch more than 2 hours per day. Other types of close-up work including reading, writing, and using computers is more associated with myopia than TV-viewing.
