OBJECTIVE: To determine risk factors for HIV infection and to study time
trends of HIV seroprevalence in intravenous drug users (IVDU) in Berlin
(West). METHODS: From 1984 to 1989 784 heterosexual IVDU were recruited
anonymously from facilities for drug treatment and counselling.
Serological tests were carried out for HIV, hepatitis A and B, lues and
toxoplasmosis. Data on social and behavioural features were collected.
RESULTS: 23.2% were seropositive for HIV. Seroprevalence rates of
hepatitis B, hepatitis A and lues were 67.1%, 39.5%, and 3.9%,
respectively. HIV seropositivity was significantly associated with
sharing of injection equipment, imprisonment and intravenous drug use in
prison. The crude time trend of HIV seroprevalence (concerning the year
of the last iv drug use) shows an increase from 17.9% in 1983 to 29.1%
in 1985, and decreases to 17.2% in 1988. The estimated HIV
seroprevalence odds, adjusted for temporal changes in the study group,
show an increasing trend over the last years. CONCLUSIONS: The increase
in the adjusted HIV seroprevalence odds suggests that continued efforts
are necessary to reduce the spread of HIV among IVDA in Berlin (West).
As more detailed data indicate, IVDU of young age and in prison should
be main target groups for AIDS prevention.
