Effects of HIV-prevention interventions for samples with higher and lower percents of Latinos and Latin Americans: a meta-analysis of change in condom use and knowledge

Abstract

This meta-analysis (N=110,092) assessed the efficacy of HIV-prevention interventions across samples with higher and lower concentrations of Latinos/Latin Americans. Findings indicated that groups with higher percents of Latinos increased condom and HIV-related knowledge to a lesser extent than groups with lower percents of Latinos/ Latin Americans. Moreover, groups with greater percents of Latinos/Latin Americans only benefited from intervention strategies that included threat-inducing arguments, whereas groups with lower percents of Latinos/Latin Americans benefited from numerous strategies. In addition, groups with greater percents of Latinos/Latin Americans increased condom use when interventions were conducted by a lay community member, whereas groups with lower percents of these groups increased condom use the most in response to experts. Not surprisingly, there were important differences among Latinos/Latin Americans with different education levels, different genders, and US/Latin American nationality.
