Florida Cohort carried out in 3 waves

The goal of the Florida Cohort is to assess how individual, clinic, and community level factors influence healthcare accessibility and utilization and HIV clinical outcomes across the state of Florida. We seek to be representative of all people living with HIV in Florida and will also include some people who do not have HIV. The study will help identify barriers to care and treatment that could be changed by future interventions to improve the health outcomes of Floridians living with HIV and other chronic conditions.  We will work with the Florida Department of Health to continuously follow HIV viral load and CD4 counts from all persons enrolled in the cohort. The Cohort will also help build relationships between researchers from around the state.

This study has been carried out in three waves:

  • Wave 1 took place between 2012 and 2013.
  • Wave 2 took place between 2014 and 2017 and enrolled 900 participants from Gainesville, Lake City, Tampa, Orlando, Miami, Sanford, Ft. Lauderdale. 
  • Wave 3 will begin recruiting participants in 2020! This wave will focus on mental health and substance use among people living with HIV, including transgender persons. This study will recruit 750 participants from across the state of Florida

AIMS

This will be the largest prospective cohort study focused on the health effects of marijuana in PLWH. The findings will inform HIV treatment providers and patients who are considering marijuana to manage HIV-related symptoms or HIV disease itself, and will identify patterns of marijuana use that are most strongly associated with the incidence of substance use disorders.

  • Determine the association of daily and occasional marijuana use with HIV care engagement, viral suppression, and HIV disease progression
  • Determine the association of past and current marijuana use with cognitive function, motivation, and planning
  • Determine the association of chronic marijuana use with cytokine markers of chronic inflammation.

COMMUNITY RESOURCES

SHARC’s research happens across the state of Florida in Gainesville, Orlando, Tampa, Miami, and more. We believe access to resources is important for our communities and their health. For the Gainesville, Orlando, Tampa, Broward County, and Miami areas, we have created resources guides to support you.
