Researchers from University College London discovered that girls, in particular, are more likely to have a high BMI if they have a television in their bedroom.

Experts suggest that the longer children spend watching the television, the higher the chances of them being overweight. In light of the findings of the study, researchers have now called for further research into the correlation between obesity in children and the use of laptops, tablets and mobile phones.

The findings of the study have been published in the International Journal of Obesity. Researchers used data from 12,000 children living in the UK. They found that almost 50 percent of children had a TV in their room at the age of 7 years old. Parents involved in the study were asked to respond to questions, including how many hours of TV children watched per day. After 4 years, data was analysed from the children at the age of 11. The research team established that those with a TV in their room were more likely to be overweight. The risk of obesity was 30 percent higher in girls who had a TV in their room at the age of 7 compared to those who didn’t. In boys, the risk was around 20 percent higher.

Dr Anja Heilmann, from the research team at UCL, explained that the study suggests a clear link between obesity risk and exposure to television. The reasons are unclear, but experts believe that children who watch TV in their bedrooms are more likely to snack and graze, live a more sedentary lifestyle and get less sleep than those who don’t watch TV in their rooms.
