If all states were performing as well as Iowa and 4 other top-ranked states, 4.6 million more U.S. children would have health insurance.
Researchers at the Commonwealth Fund, New York, have published data backing that assertion in a report covering 13 measures of states' success at providing high-quality health care for children.
Iowa came in first. The other states ranking in the top 5 are Vermont, Vermont, Maine, Massachusetts and New Hampshire.
The 5 lowest-ranked states for children's health care are Arizona, Louisiana, Mississippi, Florida and Oklahoma.
The 13 performance indicators used include measures representing access to care, quality of care, cost of care, children's potential to lead healthy lives, and "equity," or fairness.
