IOWA CITY, Iowa (AP) — A new study says that 3 percent of Iowa children do not have health insurance, one of the lowest rates in the nation that could nonetheless be improved. The University of Iowa’s Public Policy Center says it conducted a telephone and Internet survey in 2010 and 2011 that concluded the rate of uninsured children was roughly unchanged from five years earlier.

The study says that most of the uninsured children come from families that would be eligible for existing government programs such as Medicaid and hawk-i. Its authors are calling for continued outreach to get them enrolled and are holding a webinar to discuss the report today (Tuesday).

The report notes parents will have incentives to get their children insured under the Affordable Care Act, which mandates that individuals obtain insurance.
