Despite the Obama Administration's outreach effort to inform and enroll Latinos in health insurance through the Affordable Care Act (ACA,) a new survey shows that 1 in 4 Latinos still have not heard of President Barack Obama's signature health care law.

The groundbreaking study, titled The Latino National Health and Immigration Survey, was sponsored and designed by the Robert Wood Johnson Foundation Center for Health Policy at the University of New Mexico and implemented by Latino Decisions.  In the survey, which was conducted from Jan. 29, 2015, to March 12, 2015, researchers found that Latinos have the highest rates of uninsured of all ethnic groups in the country.

To help spread awareness about the benefits of signing up for ACA or Obamacare, the Department of Health and Human Services tripled its spending this year on media targeting the Hispanic community. The HHS also teamed up with national groups like Enroll America to hold over 600 local enrollment events in January.

Although there have been some improvements in enrolling Latinos into Obamacare, 25 percent of respondents in the survey said they had heard or read "nothing at all" about the ACA exchanges, while 28 percent said they knew "not that much" about them.

In spite of the lack of knowledge regarding health care exchanges, the survey shows that 82 percent of Latinos have health insurance.

"The Affordable Care Act, in terms of expanding access to health insurance specifically for the Latino population, is clearly working," said Gabriel Sanchez, executive director of the RWJF Center for Health Policy at the University of New Mexico and Director of Research at Latino Decisions, according to U.S. News.

The study also notes that there is a gap in coverage between Latinos born in the U.S., who have a coverage rate of 87 percent, and immigrants, who have a coverage rate of 78 percent.

Furthermore, the research indicates that the lack of engagement with the marketplaces and health care providers among 78 percent of Latinos is caused by the perception of anti-immigrant or anti-Hispanic attitudes in the country.

"One of the most concerning narratives about the state of life in Latino America is the extent to which some are 'living in the shadows,'" Francisco Pedraza, assistant professor of political science at Texas A&M University, noted in a statement. "We found that 1 in 3 Latinos are holding back in some form from full engagement in public life in order to avoid scrutiny of their citizenship status. This includes ... making appointments with health care providers."
