Even though one out of three American children live within a mile of their school, almost not half of those students often bike or walk to class, scientists report.
Children who live in the South, in country areas, or who have college-educated parents, are among those least likely to bike or walk to school, notes the report, which is published in July.
Sarah Martin and her workmates at the US Centers for Disease Control and Prevention (CDC) studied materials from more than 7, 000 children between 9 and 15 years of age.
They found that almost 35 percent of the children lived within one mile of their schools. Children between 11 and 13 years old were more likely to walk or bike than 9-year-olds. Children whose parents had a high school education were more likely to bike or walk than children with college-educated parents.
"The majority of children are missing an opportunity to increase daily physical activity," Martin said in a prepared statement.
According to the CDC, nearly one in five (18. 8 percent) children between 6 and 11 years old are overweight. Increased daily physical activity is one of the methods the CDC gives to help deal with obesity (肥胖)in children.
Martin said that there are all kinds of reasons why children in city areas might be more likely to bike or walk. They said the fact is that schools may be in mixed-use neighborhoods where it is more possible to bike or walk, compared with other places where there may be fewer safe sidewalks.
