Hypothesis
Sexual and social relationships would factor prominently as HIV-related risk factors among female injection drug users.
Conclusion
HIV prevalence is significantly higher among female injection drug users compared to males, and geographic mobility influences HIV risk differently by gender.
Supporting Evidence
- HIV prevalence was higher in females (10.2%) compared to males (3.5%).
- Deportation from the U.S. was a significant factor for higher HIV risk among male IDUs.
- Factors associated with higher HIV prevalence among females included younger age and lifetime syphilis infection.
Takeaway
This study found that women who use drugs in Tijuana are more likely to have HIV than men, and moving to the city can change their risk of getting HIV.
Methodology
Injection drug users were recruited using respondent-driven sampling and underwent testing for HIV and syphilis, along with structured interviews.
Potential Biases
Potential underreporting of drug use and HIV status due to stigma.
Limitations
The study is cross-sectional, limiting causal inferences about the relationship between migration and HIV risk.
Participant Demographics
Of 1,056 participants, 896 (86%) were male and 157 (14%) were female, with most being Mexican-born.
