Disparities along the HIV care continuum among Latinos

May 25, 2017 @ 10:00 am - 11:00 am

Presentation Abstract

Diana Sheehan, MPH, PhD

The HIV care continuum consists of several steps required to achieve viral suppression in people living with HIV from early diagnosis to antiretroviral (ART) adherence. Viral suppression and ART adherence have been linked to immunologic improvement and preservation and decreased risk of HIV transmission. However, only 31% of Latinos living with HIV in the US are virally suppressed. Using Florida HIV/AIDS surveillance data and multilevel modeling, we quantified disparities along each step of the HIV care continuum among Latinos ages 13 and older. Our population-based cohort studies suggest that Latinos born in Mexico and Central America are at significantly increased risk of delayed HIV diagnosis, non-retention in HIV care, and non-viral suppression compared with US-born Latinos. Nevertheless, our research suggests that targeting engagement in HIV care has the potential to drastically improve viral suppression among Latinos born in Mexico and Central America sufficient to eliminate disparities. Furthermore, Black Latinos are at significantly increased risk of non-viral suppression compared with White Latinos; however, this disparity disappears after controlling for neighborhood disadvantage. Finally, our studies have documented significantly increased risk of delayed HIV diagnosis among Latinos living in ethnic enclaves, and non-linkage to care among Latinos living in disadvantaged and rural neighborhoods. A presentation of ongoing and future work and areas of collaboration will also be included.

About the Lecturer

Dr. Diana Sheehan is a postdoctoral research fellow in the Department of Epidemiology at the Robert Stempel College of Public Health and Social Work at FIU. Her research aims to ameliorate disparities along the HIV care continuum among Latinos and socioeconomically disadvantaged populations using a socioecological framework. Dr. Sheehan’s health disparities work emphasizes the contribution of social and cultural determinants of health, as well as contextual determinants including residential neighborhood, social and ethnic networks, and the health care system. Dr. Sheehan has been funded by the National Institute on Drug Abuse (NIDA) and the HIV Prevention Trials Network (HPTN). Her work has received several recognitions including an award by the National Hispanic Science Network. Dr. Sheehan is a current fellow of the Interdisciplinary Research Training Institute on Hispanic Drug Abuse and a former Scholar in Health Disparities from the Center for Substance Use and AIDS Research on Latinos in the United States. Dr. Sheehan received a PhD in Public Health from FIU, and a Master of Public Health in International Health from Boston University.
