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. Homeless IDU women may be an important residual risk group warranting future preventive interventions and women with a history of STD should be a particular target for health education. Differences in HIV prevalence across cities are very large and may be related to differences in harm reduction policies.
The objective of this study was to describe factors associated with imprisonment of female injecting drug users (IDUs) and to assess if female IDUs who have been in prison have different HIV risk behaviours when compared to females IDUs who have never been incarcerated. A seroepidemiological survey was conducted of 304 female IDUs recruited in outreach and treatment programmes in Madrid, Spain. Data on sociodemographic characteristics and recent and lifetime risk factors, sexual and reproductive history and history of imprisonment were collected. Bivariate analysis and a logistic regression model were used to identify factors associated with imprisonment. Risk factors for imprisonment were having illegal sources of income, not having a fixed address, leaving education before finishing primary school and starting injection of drugs early in adolescence. HIV risk behaviours were highly prevalent among this population of female IDUs and drug injection in prison was reported by more than one-third of those who had ever been imprisoned. In addition, recent HIV risk behaviour indicators were not associated with imprisonment, suggesting that incarceration did not lead to risk reduction after release from prison. Female IDUs who have been in prison have substantial reproductive health problems that require gynaecological care. These results point to the urgent need for prevention programmes which address HIV and other blood-borne infections using gender specific approaches for women IDUs incarcerated in Spanish prisons.
In order to examine the prevalence of HIV infection and associated risk factors amongst Spanish female prostitutes a multicentre (n:22) cross-sectional study was conducted between November 1989 and January 1991. Data collected included socioeconomic characteristics, sexual behaviour and health status together with blood samples. A total of 1633 prostitutes were recruited into the study. Of these, 1433 (87·8%) consented to blood samples being taken and 180 (12·6%) were HIV positive. HIV seroprevalence was 54·7% for intravenous drug users (IVDUs) versus 3·7% for non-IVDUs. Previous imprisonment, hepatitis B and a partner who was an IVDU were significant predictors of HIV infection according to multivariate logistic regression models.
The results of a multicentre study of 1668 Spanish prostitutes are described with regard to syphilis infection. For those women who permitted serological tests (n = 1095), 30.59% (confidence interval (CI): 30.55%-30.63%) were positive for markers indicating current or prior infection. After adjustment was made for other variables, a significant association with syphilis infection was observed for periods of exposure (i.e. age and years working as a prostitute). No significant associations were detected for either intravenous drug use, or educational attainment. The results of this study are similar to those of some other investigations into the prevalence of syphilis amongst prostitutes.
