"Both adults and kids lost private coverage over the past decade," Dr. Thomas Frieden, director of the C.D.C., said at a news conference, according to the Reuters news agency.
There was one nugget of good news in the report: While from 2008 to 2009, the number of adults aged 18 to 64 years without insurance for at least part of the year increased 5.7 percent (from 46.0 million to 48.6 million,) the number of children less than 17 years old without coverage for at least part of the year decreased 5.0 percent, (from 10.0 million to 9.5 million.)
All these figures are likely to throw gasoline on the fire of the public health care debate awaiting next year's Congress.
Republican House Speaker-in-waiting John Boehner has said he believes Republicans were elected in order to repeal sweeping health reforms passed last year that were in part aimed at finding coverage for the uninsured. One of the ways Republicans say they plan on addressing healthcare reforms is by defunding the reform's initiatives. Regardless, many predict political gridlock during the next two year in implementing health reforms.
Another important aspect of the debate that is likely to come up again is the Children's Health Insurance Program, or CHIP, the under 18 years old version of Medicaid. Only 41 Republicans voted for the 2009 expansion of the program, and President George Bush vetoed two previous attempts at extending federal health coverage to more American children.
"As private insurance coverage fell, the safety net protected children, but did not adequately protect adults," Frieden said.
Nine percent of adults lost private insurance, and public insurance picked up just 5 percent of them, the CDC said. Frieden said 22 percent of adults aged 18 to 64 are uninsured.
The CDC analyzed data from the National Health Interview Survey or NHIS for 2006, 2007, 2008, and 2009 and the first quarter of 2010 for its report. One of the many discoveries of this in-person survey conducted by the CDC was the shifting makeup of the uninsured population of America.
"The first myth is that it's only the poor who are uninsured," Friden said. "In fact, half of the uninsured are over the poverty level and one in three adults under 65 in the middle income range--defined arbitrarily here between $44,000 and $65,000 a year for a family of four--were uninsured at some point in the year."
