A new study suggests that about 40 percent of youths in the United States experience at least one physical assault each year.
Researchers at the University of New Hampshire's Crimes Against Children Research Center conducted random telephone interviews in 2011 with about 4,500 minors or their caregivers.
Nearly 14 percent of those surveyed reported repeated maltreatment by a caregiver, according to the study.
In addition, more than 13 percent reported being physically bullied; nearly one in three said they were emotionally bullied.
