'Long-term harm' of too much TV for toddlers


Recommended Posts

The more TV a toddler watches, the higher the likelihood they will do badly at school and have poor health at the age of 10, researchers warn.

The study of 1,300 children by Michigan and Montreal universities found negative effects on older children rose with every hour of toddler TV.

Performance at school was worse, while consumption of junk foods was higher.

UK experts said parents could allow young children to watch "some" high quality TV.

On average, the two-year-olds watched just under nine hours of TV per week, while for four-year-olds the average was just under 15 hours.

But 11% of the two-year-olds and 23% of four-year-olds watched more than the recommended maximum of two hours of TV a day.

When the children were revisited at the age of 10, teachers were asked to assess the children's academic performance, behaviour and health, while body mass index (BMI) was measured at 10 years old.

Higher levels of TV viewing at two was linked to a lower level of engagement in the classroom and poor achievement in maths.

Researchers also found a decrease in general physical activity but an increase in the consumption of soft drinks and in BMI (body mass index).

"Our findings make a compelling public health argument against excessive TV viewing in early childhood."
