UMiami: Interventions That Incorporate Social Networks Can Have Positive Effects on HIV Prevention and Treatment Outcomes, Study Finds

Many Latina seasonal workers reside and work in Miami-Dade County, a location that is known to have the highest HIV incidence in the U.S. While this rate is four times the national average, there are no prevention interventions that aim to decrease HIV among Latina seasonal workers.

A study published in the International Journal of Environmental Research and Public Health compared the outcomes of two interventions – VOICES and HEALTHY – which were adapted to include a respondent-driven social network component. Each participant was asked to recruit three friends, and those friends were asked to recruit three more friends. There was a total of 20 groups of 13 friends.

Researchers collected data at baseline, as well as during the six and 12 months after the interventions were completed. A total of 261 Latina seasonal workers participated in either of the two interventions. There were significant changes in cognitive factors, behavioral factors, and cognitive factors. This study supports the literature that suggests that interventions that incorporate social networks can have positive effects on HIV prevention and treatment outcomes, including sustained benefits beyond study periods.
