AB OBJECTIVES: To compare risk behaviors for HIV infection among IDUs in
Santos (S) & Rio (R), Brazil. These are the largest ports in South
America, and have the first (Santos) and 12th (Rio) highest incidence
rates for AIDS in Brazil. METHODS: 479 IDUs in Rio and 220 in Santos
were interviewed using the WHO multicity methodology and questionnaire.
Behavioral data reported are for the six months prior to the interview,
except as mentioned otherwise. RESULTS: The mean age of the two samples
was similar (around 28 years old) and in both cities cocaine was
injected by over 95% of the sample. Significant differences were found
in sex ratio (Santos 42% female vs. Rio 13% female; p < .0001) and
recruitment site--street/treatment. center--(S = 55% street recr. vs. R
= 32% street recr.; p < .0001). IDUs in Santos both injected
significantly more frequently (S = 51% vs. R = 33%; p < .0001, for
frequencies of injection > 3x a week) and engaged more in syringes
sharing (S = 54% vs. R = 30%; p < .0001), similar proportions of those
interviewee of the 2 cities (S = 61% vs. R = 68%) cleaned injection
equipment but most of them (S = 82% vs. R = 88%) only with water.
Sexually active IDUs in Rio were more likely to never use condoms than
their counterparts in Santos, both with primary partners (S = 69% vs. R
= 83%; p < .004) and occasional partners (S = 46% vs. R = 63%; p < .007)
of the opposite sex. On the other hand, sex with clients, of the
opposite sex, was much more frequent in Santos than in Rio (S = 35% vs.
R = 6%; p < .0001). Male-to-male sexual contacts, in the last 5 years,
were reported by 36% of the males interviewed in Santos and 36% in Rio.
For those engaged in male male-to-male sexual contacts in the last 6
months, most of them (S = 67% vs. R = 73%) never used condoms.
CONCLUSIONS: Despite the major differences observed, both
cities--important transhipment routes of cocaine, are deeply afflicted
by the HIV spread among their IDUs (seroprevalence for HIV in the
samples: S = 63% & R = 33%), with possible important further spread to
their sexual partners and offspring.
