RESUMO
A growing body of research suggests that acculturation may play a role in the disproportionate likelihood of sexual risk behaviour and STI/HIV infection among Hispanic youth in the USA. We systematically reviewed the relationship between acculturation and STI/HIV-related sexual risk behaviour among Hispanic youth aged 13-24 by reviewing studies that have used a bidimensional acculturation approach. Electronic databases were searched with the searches limited to articles published in 1992 when the concept of bidimensional acculturation was introduced or later. Two independent researchers screened the full data set to assess eligibility. Six studies were included. Three studies used cross-sectional data, while the other three used longitudinal data. We discovered that sexual risk behaviours differed by Hispanic youth acculturation types and were moderated by gender. We found that Hispanic acculturated youth had lower odds of having multiple sex partners than US acculturated youth. However, the relationship between acculturation and condom use yielded contradictory results and we could find no report on bi-culturation and sexual behaviour. Additional research is needed to explore whether adopting both US and Hispanic-heritage cultures at the same time may reduce or increase the odds of engaging in sexual risk behaviour among Hispanic youth in the USA.
