    Notes: Aims. To measure risk behaviour among injecting drug users (IDUs) using the Injecting Risk Questionnaire (IRQ). Methods. Data were analysed from the first multi-site survey of injecting risk behaviour among IDUs not in contact with drug services in England. A total of 1214 IDUs were recruited from community settings in seven sites. Findings. Fifty-two per cent reported sharing injecting equipment in the previous 4 weeks in response to a single question on sharing. This rose to 78% when asked more detailed and multiple questions on injecting risk practices. Levels of injecting risk behaviour did not differ substantially by gender, age, length of injecting career, main drug of injection, previous treatment contact or geographical location. However, sharing partners were restricted to a median of two others. Conclusion. These data raise questions concerning the extent to which levels of injecting risk behaviour have increased over recent years, or the extent to which previous monitoring systems underestimated levels of risk. None the less, the data confirm that the promotion of safer injecting continues to be an important public health issue with regard to reducing blood-borne infections.

    Notes: Fears of a crack ‘epidemic’ in the United Kingdom of the kind experienced in the United States remain unfounded. However, findings from an ongoing serial point HIV prevalence study indicate that the use and injection of crack cocaine among injecting drug users (IDUs) in London is on the increase. Data on patterns of drug use and drug injection were collected over 4 years (1990–93), from IDUs recruited from both drug treatment and community-based settings. All respondents were asked about their drug use in the 6-month period prior to interview. The use of crack cocaine increased significantly from 16% in 1990 to 59% in 1993 and the injection of crack cocaine from 1% to 27%, respectively. The findings suggest that crack cocaine is being injected more regularly, with increases over the 4-year period in those who reported injecting the drug at least once per week. In response this paper considers both the health implications of, and the treatment response to, the increasing use and injection of crack cocaine among IDUs in London.

    Prevalence of markers for hepatitis B virus and HIV-1 among drug injectors in London: injecting careers, positivity and risk behaviour (1996)

    Notes: Concerns about the risks of HIV infection among drug injectors have eclipsed concerns about the prevalence and transmission of hepatitis, and in particular hepatitis B virus infection. Findings are reported from surveys undertaken with two separate community-recruited samples of drug injectors in London collected in 1992 (n = 505) and in 1993 (n = 507). Anonymized confirmed testing of saliva snows 51.5% of drug injectors in 1992 and 47.9% in 1993 to be antibody positive to the core antigen of hepatitis B virus (anti-HBc). Approximately half of the drug injectors confirmed as anti-HBc positive were unaware that they had been infected with hepatitis, Anti-HIV-1 prevalence was considerably lower at 7.0% in 1992 and 6.9% in 1993. Multivariate analyses showed anti-HBc positivity to be most likely among older injectors with longer injecting careers who had a history of having shared used needles and syringes. HIV-1 positivity was also associated with a history of having shared injecting equipment as well as with recent sharing (i.e. in the last 6 months). Unlike anti-HBc positivity, there were no associations between HIV-1 positivity and age or length of injecting career. Younger injectors with shorter injecting careers were more likely to report recent sharing of used injecting equipment than older injectors with longer injecting careers. We note the potential for continued transmission of HBV and HIV-1, particularly among younger injectors. We recommend an integrated strategy to maximize the health of drug injectors, of which HIV and HBV prevention is a part. There is a need to widen the availability of HBV vaccinations for HBV negative drug injectors and their sexual partners and for clear guidelines to drug injectors about the relative efficacy of bleach to disinfect injecting equipment of HBV and HIV.

    Continued risk behaviour among HIV positive drug injectors in London: implications for intervention (1993)

    Notes: Findings are reported on the risk behaviour of 104 confirmed HIV-1 antibody positive drug injectors in London. Findings indicate that 41.3% of respondents had never received treatment or help for their drug use, and that 52.0% had never received a named test for HIV antibodies. The majority of confirmed HIV positive respondents (70.1%) were unaware of their HIV positive status. Respondents unaware of their HIV positive status were less likely to use condoms with primary sexual partners than respondents aware of their HIV status, and were marginally (though not significantly) more likely to report borrowing and lending used injecting equipment. Overall levels of risk-taking were similar to those reported in UK studies of injecting drug use as a whole. The paper concludes by emphasising the high potential for HIV transmission among the equipment sharing and sexual partners of HIV positive drug injectors and by stressing the importance of low-threshold HIV testing, education and treatment interventions in the community. If significant proportions of HIV positive drug injectors remain unaware of their antibody status, and if they also continue to engage in behaviours of risk to others, the spread of HIV among drug injectors and their partners may escape current efforts of prevention and prevalence control.
