This cross-sectional study compares sexual risk behaviours among a sample of young adult substance users in Miami (N=602) with and without foster care histories.Methods Participants completed a comprehensive assessment which included sections on foster care, sexual risk behaviours and related health and social problems. Logistic regression was used to examine the relationship between foster care history, associated syndemic vulnerabilities and increased likelihood of having a prior HIV/STI diagnosis.Results Bivariate analyses indicated that foster care alumni were more likely to report a prior HIV/STI diagnosis, higher condomless sex frequencies, being high on alcohol or drugs during sex, sexual victimisation and a history of homelessness compared with other participants in the sample (p<0.05). Multivariate analyses revealed that foster care history, sexual victimisation and group sex participation are associated with a prior HIV/STI diagnosis (p<0.05). Group sex participation doubled the odds of a prior HIV/STI diagnosis for foster care alumni, compared with other participants (p<0.5).Conclusions This exploratory study identifies characteristics that distinguish foster care alumni from non-alumni and signals the need to better serve the sexual and related health needs of individuals with foster care histories. Clinicians and healthcare providers should provide foster care alumni with detailed HIV/STI risk reduction information and resources and services to address related syndemic vulnerabilities (eg, victimisation and homelessness).
