Angela M Robertson, Gudelia Rangel, Gustavo Martinez, Monica D Ulibarri, Jennifer L Syvertsen, Samuel A Bazzi,
Scott Roesch, Heather A Pines, and Steffanie A Strathdee
IAS 2014, Melbourne, Australia
Funding: National Institutes of Health (NIH) grants R01 DA027772, R36 DA032376, T32 AI007384, T32 DA023356, K01 DA026307, and P30 AI060354-10 . Contact: [email protected]
Setting: Mexico-U.S. border
2
Sex work is socially tolerated and quasi legal in many Mexican border cities; high HIV/STI risk among sex workers/clients
Cohort of Sex Workers & Intimate Partners
• Proyecto Parejas: prospective mixed methods study of HIV/STIs among 214 sex workers & their 214 intimate male partners (n=428) in Tijuana & Ciudad Juarez, Mexico – Most couples always had unprotected sex together; condoms used for sex work
– Heavy current drug use (62% heroin, 54% stimulants, 62% injected any drugs)

Findings Highlight Social/Economic Contexts of Risk
4
Time-varying predictors of new STIs (w/o HIV):• Recent stimulant use
(meth, crack, cocaine) increases women’s risk (aOR: 2.13; CI: 1.07–4.28)
• Women having regular sex work clients decreased their male partners’ risk (aOR: 0.38; CI: 0.14–1.03)
Female Sex Workers
Intimate Male Partners
Incidence of all STIs among FSWs than their male partners
• Women who reported physically assaulting partners also had decreased risk (aOR: 0.44; CI: 0.22–0.86)
More research is needed to understand how conflict and sex work earnings impact couples’ risk
• Couple interventions to promote communication and reduce conflict are needed

CONCLUSIONS Interventions that increase empowerment of sex workers (i.e., choice of clients, ability to avoid violence) may reduce their own HIV/STI incidence and that of their intimate male partners.
