Some working age Americans may be losing touch with health insurance.
A new study shows 41 percent of people with moderate to middle incomes didn't have health insurance for at least part of last year.
That's up from 28 percent without coverage in 2001.
The Commonwealth Fund study also says more than half of the uninsured adults say they're having problems paying their medical bills or have gone into debt to cover their expenses.
The survey of 4,300 adults shows people without insurance are more likely to skip recommended health screenings than those with coverage, and are less likely to have a regular doctor than people who have health insurance.
The Commonwealth Fund is a private, health care policy foundation.
