When it comes to healthcare, many lower-income adults report being unsure how they will be able to pay their medical expenses. A large number of those surveyed are not confident in their ability to juggle bills, according to an AARP survey.

The survey reveals that more than 40 percent of low-income adults over the age of 45 say their health is "fair" to "poor," whereas less than 20 percent with an annual salary exceeding $25,000 reported the same feeling.

The study also revealed that almost 40 percent of respondents had to delay or even cancel a healthcare appointment within the last six months. AARP Foundation president Jo Ann Jenkins says tough economic times are hitting low-income Americans hard.

"Each day, millions are choosing between essentials like buying groceries or paying for prescriptions. It's a devastating choice that no one should have to make," says Jenkins.

Going without adequate healthcare can result in greater expenses down the road. Those who struggle to pay for their healthcare may want to consider researching insurance plans. People can go online to get health insurance quotes and to find a policy with premiums that fit into their budget.
