Surprising trend toward better outcomes for Hispanics
OAKLAND, Calif., July 20, 2009 – Kaiser Permanente researchers found no disparities by race or ethnicity in risk of AIDS and death among HIV-infected patients in a setting of similar access to care. This is despite lower Anti-Retroviral Therapy adherence among Hispanics and African-Americans compared to whites. Researchers also saw a trend toward better outcomes for Hispanics.
The study, which appears online in The Journal of General Internal Medicine, is one of the largest to date to evaluate racial and ethnic differences in clinical outcomes among HIV-infected patients.
The study was a retrospective observational cohort study from 1996 to 2005 in Kaiser Permanente, an integrated delivery system with more than 3 million members in Northern California. Researchers studied 3,106 whites, 919 Blacks and 661 Hispanics infected with HIV and looked at differences in ART adherence, new AIDS events and all-cause mortality.
"This observation of reduced mortality in HIV-infected Hispanics is somewhat surprising giving the observed lower adherence rates, reduced immunological responses and lower census-based socioeconomic status compared to whites," said Silverberg. Hispanics had particularly low numbers of cardiovascular and cancer-related deaths. He explained that this phenomenon, also called the Hispanic Paradox, may occur because of differences in diet, genetics and extended family support.
This study is part of Kaiser Permanente's larger ongoing work to end health disparities by providing equitable access and care to its 8.6 million members, by targeting resources to areas in need in communities across the United States, by investing in disparities research, and by implementing strategies that support equity in health nationwide, including universal health coverage. ###
Additional investigators on the study include Wendy Leyden, MPH, Charles P. Quesenberry, Jr., Ph.D., and Michael A. Horberg, MD, MAS, all affiliated with the Kaiser Permanente Division of Research in Oakland, Calif. The research was funded by a Community Benefit grant from Kaiser Permanente Northern California, and a career development award from the National Institute for Allergy and Infectious Diseases, part of the National Institutes of Health.
