While some people are spending less, a much larger percentage of Americans are spending more this year on health care.
The latter is about 40 percent, according to a new report from Bankrate Inc., an online publisher of personal finance content.
Bankrate also found that 28 percent of Americans are feeling more negative about the Affordable Care Act compared to a year ago. That was twice as many as the positive. One in four say it is more difficult to handle medical expenses now than it was a year ago.
There remains a lot of uncertainty about how the ACA will affect current health coverage, whether it's really going to take effect and even what it is, according to Bankrate.
"We're just three weeks away from when the new health insurance exchanges will begin accepting applications, and we're still observing a disturbing lack of consumer education," said Doug Whiteman, an insurance analyst for Bankrate.com. "If this doesn't change soon, millions of Americans could miss important deadlines or make uninformed decisions."
The findings are part of Health Insurance Pulse, a new monthly survey that tracks how Americans are feeling about health care and their personal finances. The survey was conducted by Princeton Survey Research Associates International.
