Scientists say there is a clear link between having a TV in your bedroom as a young child and becoming overweight later in childhood | | International Journal of Obesity | Story via The Guardian
Children who have TVs in their bedrooms are more likely to be overweight than those who do not, a study by University College London scientists suggests.
Sitting still for long periods watching TV has long been thought to be one of the changes in behaviour of the last few decades that could be contributing to the obesity epidemic. It has been suspected that having a TV in the bedroom might exacerbate the problem. Children or adolescents might be snacking unobserved, they could be exposed to advertising for junk food while watching adult programmes and they may not sleep as well, which is also linked to putting on weight.
Published in the International Journal of Obesity, the research used data on more than 12,000 children born in 2000/2001 who were recruited to the UK Millennium Cohort Study, set up to look at the influences on children’s development into adulthood. They investigated the data from the age of seven to 11. More than half had a TV in their bedroom.
They found that girls who had a TV in their bedroom at age seven were at an approximately 30% higher risk of being overweight at age 11, compared to children who did not have a TV in their bedroom. Boys were 20% more likely to become overweight.
