      A new computer treatment is being used to deal with obesity in children. Connected to a small dining set,

consisting of (包括) 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 lecturer leading the treatment trials.(实验).

      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 (曲线) 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 (稳定地) and slowly

and the system teaches them to slow down. It's a bit like retraining," says Hamilton-Shield.

       Obesity now represents (代表) 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 England 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 years' time. At first, it would be managed by medical clinics (诊所).
