Study: Even 7-year-olds sometimes hurt themselves

CHICAGO (AP) — Even children as young as 7 sometimes cut themselves on purpose, according to a small study believed to be the first to examine self-injury at such early ages.

The study was based on interviews with children in the Denver area and central New Jersey, without confirmation from parents or others. But the researchers and independent experts say the results are credible and raise awareness about a disturbing problem.
