Frieden noted that the number of Americans with private health insurance coverage has dropped steadily for the past 10 years.
"The public safety net has more than protected children. But while public coverage provided some safety net for adults, it wasn't enough to offset the loss of private coverage," he said. "As private insurance coverage fell the safety net protected children, but did not adequately protect adults."
Many gaps in health insurance coverage will be closed by the provisions of the Affordable Care Act, signed into law in March by President Barack Obama, the report said. Under the new law, 94 percent of adults under age 65 will be insured by 2019.
This should help cut down on missed or delayed care. Also, the new law requires coverage of preventive care, which could save 100,000 lives each year, according to the report.
But the new health reform law remains controversial, with Americans equally divided over whether they like it, according to recent polls. And Republicans who will take control of the House of Representatives in January have pledged to make major changes to the legislation. However, Democrats still control the Senate, which would have to agree to any changes to the law.
The statistics for the new CDC report were collected from the National Health Interview Survey for 2006, 2007, 2008 and 2009, and early-release survey data from the first quarter of 2010.
