Researchers evaluate HIV prevention intervention on farmworker communities, find positive results

Latina immigrants in farmworker communities are a vulnerable and understudied population who are at a high risk for contracting HIV. Nationally, rates of new HIV infections among Latinas are more than four times that of non-Latina white women – and the rates are even higher for those in marginalized populations.  

Researchers from Robert Stempel College of Public Health and Social Work’s Center for Research on U.S. Latino HIV/AIDS and Drug Abuse (CRUSADA) recently concluded a three-year study on the effectiveness of the Centers for Disease Control’s (CDC) evidence based SEPA (Salud/Health, Educación/Education, Prevención/Prevention, Autocuidado/Self-care) program. SEPA was created by Nilda Peragallo and is a culturally tailored HIV/AIDS behavior change intervention for heterosexually active Latinas between the ages of 18 and 44 at risk for HIV and STD infection due to unprotected sex with male partners.  

“Latinas are particularly vulnerable when they are in stable, heterosexual relationships in these communities as many men do not adhere to maintaining a monogamous relationship,” said Patria Rojas, assistant professor in the Department of health Promotion and Disease Prevention at Stempel College Of Public Health and Social Work and principle investigator on the study. “Culturally, sex is an extremely private aspect of life and these women have not been taught about condom use or been given the tools to talk about their sexual health.” 

The CRUSADA researchers interviewed 240 recent Latina immigrants from Miami-Dade farmworker communities who had engaged in unprotected sex in the three months leading up to the beginning of the study. The women reported relatively low levels of formal education, with about half having less than a high school degree and came from household with an annual medium income of $23,541.  

Using the SEPA intervention, which employs demonstrations, role-play, and other capacity building exercises that together strengthen the confidence and self-efficacy of Latinas in condom use, condom negotiation, and partner communication, the study revealed significant increases in HIV prevention knowledge among participants.  

Overall, women’s self-efficacy for HIV prevention increased after the intervention with participants reported higher levels of self-efficacy after the intervention as well as indications of significant increases in condom use among participants after the intervention. 

“When women emigrate from Latin America, they come with the values from their communities, which tend to include sanctity and they believe that talking about sex is taboo. While there have been studies that show that the SEPA intervention model worked in marginalized urban settings, there was no evidence on whether it was going to be effective in rural areas such as farmworker communities,” said Rojas. “These findings give us hope that we can help this marginalized community of women who are at the high risk of contracting HIV so that they can live safer, healthier lives and be more in control of their sexual health conduct.”
