3、A new computer treatment is being used to deal with obesity(肥胖)in children.

Connected to a small dining set, consisting of scales and a plate, a mini computer teaches children how to eat and reminds them when to stop.

“In very fat people, hunger signals from the stomach to the brain stop functioning. But the new computer system teaches the children how to receive these messages again,” says Dr. Julian Hamilton-Shield, the Bristol University senior leading the treatment trials.

The computer called a Mandometer, records and stores the weight loss from the plate when children eat. As the food is leaving the plate, a curve(曲線)is produced on the computer screen suggesting whether the child is eating too quickly.

“Children with weight problems often eat too quickly. We want them to eat steadily and slowly and the system teaches them to slow down. It’s a bit like retraining,” says Hamilton-Shield.

Obesity now represents one of the major threats to the future health of children. About one in five boys and one in four girls aged two to fifteen in English are overweight. But so far no treatments have proven effective in treating children.

The Mandometer was developed in Sweden, but at present is experiencing further development at the University of Bristol, with＄224,400 in funds from BUPA—a global health and care organization, The system could be on the market in two year’s time. At first, it would be managed by medical clinics.
