(September 13, 2007 - Insidermedicine) A study just published in the Archives of Disease in Childhood reports that less than 3% of 11-year-old children in the United Kingdom do enough daily exercise.

It is recommended that kids do some form of moderate to vigorous physical activity for at least one hour every day, to promote good health and lessen the risks of becoming obese. Here are some facts concerning childhood exercise:
·    Childhood obesity is linked to the development of diabetes in adolescence and as an adult.
·    Children with type 1 diabetes who exercise regularly have lower blood pressure and cholesterol levels.
·    Although 30% of American children live within a mile of school, less than half regularly bike or walk to school.

In the latest study, researchers looked at the physical activity levels of more than 5,000 11-year-old English children for seven consecutive days. The kids wore a belt that contained a monitor to get a minute-by-minute record of the intensity and frequency of physical activity. The aim was to determine the total amount of daily physical activity and how strenuous the activity was.

The data showed that the children were about twice as physically active as adults, but were still not active enough. Boys were more physically active than girls. About 40% of the boys studied execised moderately to vigorously for at least an hour a day, compared to 22% of the girls.

We had a chance to speak to researcher Mr. Calum Mattocks, regarding his results.

The result of this under-activity in childhood could have health consequences in adulthood. The authors note "It is a sobering thought that children's activity levels actually peak at around [age 11] and decline precipitously during adolescence."

Mr. Mattocks offered his thoughts on how to rectify the problem.

The latest study is important for children and parents who are concerned with good health and avoiding health problems later in life. Being physically active every day is a good start. Those with physical or other health issues can talk with their doctor to set up an exercise program.
