Watching TV three hours a day linked to type 2 diabetes in children
Children who spend more than three hours a day in front of the TV or a computer may be at greater risk of developing type 2 diabetes.
Increased levels of body fat and insulin resistance in children were linked to regular extended periods of screen time in a new study published in the journal Archives of Disease in Childhood.
Diabetes risk factors including blood fat and glucose levels, blood pressure and resistance to insulin were measured in 4,495 children aged nine and ten from primary schools in London, Birmingham and Leicester.
Children who said they spent the most time watching TV or using electronic devices each day were found to be more likely to exhibit physical risk factors for diabetes.
“Our findings suggest that reducing screen time may be beneficial in reducing type 2 diabetes risk factors, in both boys and girls and in different ethnic groups from an early age,” wrote the researchers from St George’s, University of London.
The scientists said their findings were of “considerable potential public health interest” but emphasised further research was needed to prove the link between diabetes risk and screen time.
“This is particularly relevant, given rising levels of type 2 diabetes, the early emergence of type 2 diabetes risk, and recent trends suggesting that screen time related activities are increasing in childhood and may pattern screen-related behaviours in later life,” they said.
Previous research has suggested a link between time spent on screens and heightened type
