The U.S. government has ended several health grants to one of the nation's largest pediatricians' groups -- a move the organization says could hurt children and families across the country.

The American Academy of Pediatrics confirmed this week that the U.S. Department of Health and Human Services is canceling seven federal grants that supported programs focused on child health.

The AAP, which has criticized some HHS positions and had ongoing clashes with officials, represents about 67,000 pediatricians nationwide.

"This vital work spanned multiple child health priorities, including reducing sudden infant death, rural access to health care, mental health, adolescent health, supporting children with birth defects, early identification of autism and prevention of fetal alcohol spectrum disorders, among other topics," Mark Del Monte, the group's chief executive officer, said in a statement.
