Think your kid isn't tempted by junk food while at school? A study finds that about half of kids surveyed from public and private school had ready access to vending machines, snack bars, school stores and a la carte lines. And they're not just selling carrot sticks.

The study, released Monday in the Archives of Pediatrics & Adolescent Medicine, looked at the foods children had access to at various spots on campus during lunch time, in what they termed "competitive venues."

Fitness experts are always telling us that incorporating movement into our day is a good way to burn calories. But is it effective?

How fast do you have to walk to stay ahead of the Grim Reaper? About 3 miles an hour.

More than 5,000 children a year go the emergency room after falling from windows, a study in the journal Pediatrics finds. The study, released Monday, examines patterns of such falls in children up to age 17, and finds that younger children may be at greater risk overall.

Researchers looked at data from the U.S. Consumer Product Safety Commission's National Electronic Injury Surveillance System from 1990 to 2008. In that time there were 98,415 children treated in hospital emergency rooms after sustaining a window fall, averaging 5,180 patients per year (not included in the study were falls from car windows, tree house windows, windows in homes under construction, falls through windows and falls from window sills, since in most of those cases the child fell back into the room). Patients were grouped by age, from 0 to 4 years old -- the higher-risk group -- and from 5 to 17 years old.
