[BDSP. Notice produite par INIST R0x4d26A. Diffusion soumise à autorisation]. In the light of rising human immunodeficiency virus (HIV) incidence rates amongst women in Western Europe, a multicentred, cross-sectional study was undertaken to explore the multitude of possible factors associated with HIV in a population of female injecting drug users (IDU). Face-to-face interviews were conducted with 1198 female IDU recruited from a variety of settings in Paris, Madrid, Rome, London and Berlin. Their HIV status was determined from antibody testing of blood or saliva samples or from written confirmation of HIV test results from a physician. A hierarchical logistic regression model was used to identify direct and indirect associations between socioeconomic factors, marginalization and risk behaviour with HIV prevalence. The HIV prevalence in the sample of female IDU was 27.8% (range : 1.4% in London and 52.6% in Madrid). Factors independently associated with HIV prevalence in the regression analysis included : age>25 years (OR=2.0-2.9), left full-time education before age 14 (OR=2.4), no fixed address (OR=2.2), previous imprisonment (OR=1.4), commercial sex (OR=1.3), having a regular HIV positive sexual partner (OR=6.6), ever shared needles (OR=1.5) and any sexually transmitted disease (STD) infection in the last year (OR=1.7), The sexual behaviour and partners of female IDU in Western Europe are as important a component in explaining the HIV epidemic in this population as other risk factors, including high-risk drug taking behaviour.
