AB OBJECTIVE: To determine HIV-1 seroprevalence and HIV risk behaviors
among street-recruited IVDUs in Barcelona. METHODS: In 1993, 200 out of
treatment IVDUs (143 males and 57 females) were recruited at the street
level, by means of snow-balling techniques. Former IVDUs were used as
interviewers. Demographic, epidemiological and behavioral data were
collected by an anonymous structured questionnaire adapted from the
multicentric WHO study. Anonymous saliva samples were collected using an
OMNISAL device and were tested for anti-HIV-1 following WHO strategy II.
RESULTS: Overall, HIV-1 seroprevalence was 51%. Mean age of IVDUs was
29.5 years, and mean length of injecting behavior was 9.3 years.
Patterns of consumption in previous 6 months included 99.5% who reported
heroin use, 58% cocaine, 46.5% speedball, 75% tranquilisers, 27.5%
amphetamines and 1.5% crack cocaine. As a group, 56.5% and 64.5%
borrowed and lent injecting equipment, and 41% practiced backloading.
Among those who share, 74.4% reported always cleaning the equipment, but
40% of them do so only with water. In the previous 6 months, 77.5% of
IVDUs have been sexually active; systematic use of condoms was reported
by 25.6% and 36.1% for regular and occasional partners, respectively.
Multivariate analysis of this data will be presented to better identify
HIV-associated risk behaviors. DISCUSSION: This study has been the first
attempt in Catalonia to describe drug and sex behaviors of a population
of IVDUs not in contact with the social and health care system, as well
as the introduction of saliva tests for epidemiological purposes.
Identified risk behaviors show the need to reinforce prevention
strategies and to better explain the basic concepts of HIV transmission
to this population.
