Watching TV for more than two hours a day increases the risk of raised blood pressure in children, a study has found.
Children aged two to 10 who spent this much time in front of a TV or computer screen were 30pc more likely to have high blood pressure than those who did not.
Lack of physical activity increased the risk even more, by 50pc, scientists found. The findings, published in the International Journal of Cardiology, are based on data from 5,221 children from eight European countries collected over two years.
"The study shows the number of new high blood pressure cases and the connection between physical activity and different sedentary behaviours with the risk of high blood pressure in European children," said lead researcher Dr Augusto Cesar de Moraes, from the University of Sao Paulo.
