Sara Collins, vice president for affordable health insurance at the Commonwealth Fund in New York City, said that "this is consistent with the trends we are seeing."
The number of people without health insurance, now some 50 million, has increased along with rapidly rising health care costs, she said.
In addition, many people have high deductibles and co-pays and skimpy coverage, Collins said.
"This underscores the reason we need health care reform," she said. "The coverage expansions will be critical in terms of insuring people who don't have health insurance, and helping to make health care affordable."
People without health insurance are likely to put off care until they are very ill, Collins said.
"We know that people who don't have health insurance get care at about 50 percent of the rate as people with health insurance," she said. "So, if you don't have health insurance you are going to delay care."
Sixty percent of people without insurance delay or avoid going to the doctor when they are sick because of costs, she added.
