Research Brief: TV linked to high blood glucose in children

Extensive TV watching is associated with poor blood glucose control in children and adolescents with type-1 diabetes, say Norwegian researchers. The study examined the TV watching habits of 538 children and adolescents, with a mean age of 13. Those who watched less than one hour of TV a day had a lower level of glucose in the blood — an HbA1c level of 8.2 per cent. In comparison, children who watched more than four hours a day had an HbA1c level of 9.5 per cent (Diabetes Care Online 2007).
