The preparedness to share injecting equipment: an analysis using vignettes.

This paper reports on the use of vignettes to study drug injectors' preparedness to share injecting equipment. Separate vignettes referring to borrowing and passing on injecting equipment have been submitted to 505 injecting drug users in Glasgow. Injectors were asked to identify their own likely response in each of the situations described within the vignettes. It was shown that even among those injectors not reporting any actual sharing in the last 6 months a significant proportion would still be prepared to share injecting equipment within certain situations. The preparedness to share injecting equipment was seen to be influenced by such factors as social distance, sex and length of time injecting. It is suggested that even in situations where drug injectors may have modified their behaviour in the direction of lower levels of reported sharing, a propensity to share may remain. This suggests the continuing need to provide injectors with easy access to sterile injecting equipment; in addition, services working with injecting drug users may need to focus not only upon actual sharing behaviour but also upon what we have described here as the preparedness to share. Indeed, the latter dimension should stand as a warning to services of the potential for sharing injecting equipment to increase in the future.

Mobility of Scottish injecting drug users and risk of HIV infection.

Nine hundred and nineteen injecting drug users (IDUs) were interviewed in Glasgow, Scotland during 1990 and 1991, as part of a wider study of HIV risk behaviour, about their injecting and sexual behaviour outside the city in the previous two years. Forty-five percent of respondents injected outside Glasgow, 6% shared needles and syringes (n/s) and 20% had sexual intercourse. Much activity occurred outside Scotland but mainly within the UK, particularly London. Predictors of n/s sharing outside Glasgow during the previous two years included current injecting with and passing on of used n/s and sexual intercourse with casual partners. Predictors of sexual behaviour outside Glasgow included passing on used n/s, having sexual intercourse with casual partners and, for females, engaging in prostitution. Glasgow IDUs are a highly mobile group and although HIV prevalence remains low within this population, considerable potential for importation/exportation of HIV and other bloodborne and sexually transmitted infections exists. Further work is required to establish why IDUs travel to, and engage in high-risk activities in locations outside their home environment, and detailed data about activities such as frequency of condom usage and n/s cleaning practices need to obtained. While there is a widespread network of services for IDUs in the UK, information provided usually relates to local services and may not fully address the needs of this mobile population. Therefore, we recommend that IDUs be provided with details of facilities such as n/s exchange schemes and drug-treatment establishments in centres to where they most commonly travel.

Why do men buy sex and what are their assessments of the HIV-related risks when they do?

The belief that female prostitution might play a key role in the heterosexual spread of HIV infection has led to a great deal of attention being focused on the activities of women who sell sex. By contrast, the activities of men who buy sex has been largely ignored. One of the reasons for this has undoubtedly been the difficulties of contacting such men. In this paper data from telephone interviews with 70 men who had recently purchased sex are presented. It is shown that there was a wide range of factors that the men cited in explaining the appeal of commercial sex. The paper also reports on the males' views as to the risks of HIV associated with commercial sex. Although the men believed HIV to be very widespread amongst women selling sex, hardly any of them felt at risk themselves as a result of their commercial sexual encounters. The basis for the men's optimism about avoiding HIV and their preparedness to inform other sexual partners about their prostitute contacts are also described.

HIV risk behaviours among female prostitute drug injectors in Glasgow.

This paper focuses upon HIV-related risk behaviours of 51 female drug injecting prostitutes, interviewed as part of a serial cross-sectional study of injecting drug users in Glasgow. Forty-five per cent injected with used needles and syringes in the 6 months prior to interview. Condom use in private sexual relations was low with only 9% of those with primary partners and 22% of those with casual partners reporting consistent use of condoms with these partners. In contrast, use of condoms for all commercial sexual encounters was almost universal. Prevalence of HIV was 2.2%. Despite this low prevalence, we conclude that the level of injecting-related and private sexual risk behaviours reported here requires the continuing monitoring of drug injecting prostitutes in Glasgow.

Female streetworking prostitution and HIV infection in Glasgow.

OBJECTIVES: To identify the extent of HIV infection and injecting drug use among female streetworking prostitutes in Glasgow; to estimate the size of the female streetworking prostitute population in the city; and to estimate the number of HIV positive women working as prostitutes on the streets in Glasgow. DESIGN: Observation and interviewing of female prostitutes over seven months in red light district; analysis of saliva samples for presence of antibodies to HIV; capture-recapture approach to estimating the size of the female streetworking prostitute population. SETTING: Glasgow. SUBJECTS: 206 female streetworking prostitutes. MAIN OUTCOME MEASURES: Number of women with antibodies to HIV, self reported use of injecting drugs, history of contact with 206 women. RESULTS: Saliva samples were requested from 197 women; 159 (81%) provided samples. Four (2.5%, 95% confidence interval 0.7%-6.3%) of the samples were positive for HIV, all of which had been provided by women who injected drugs. Of the 206 streetworking women contacted 147 (71%) were injecting drug users. About 1150 women are estimated to work on the streets in Glasgow over a 12 month period. CONCLUSIONS: HIV is not as widespread among female prostitutes as many reports in the tabloid press suggest. A greater proportion of female streetworking prostitutes in Glasgow are injecting drugs than has been reported for other British cities.

Selling sex: female street prostitution and HIV risk behaviour in Glasgow.

Female prostitutes have often been seen as a major source of HIV infection. In this paper we report on a study of HIV-related risk behaviour among street prostitutes in Glasgow. This paper is based on street interviews using a standardized schedule with 68 women. We focus on the extent of HIV testing amongst the women, travel, the sexual services provided, the use of condoms with clients and private partners, and the extent of drug injecting and equipment sharing by the women. It is shown that female street prostitution within Glasgow is, at present, unlikely to be associated with significant heterosexual spread of HIV as most commercial sex is with a condom. However, some risk activities are continuing. Additionally, prostitutes report worrying rates of condom failure with clients. It is suggested that attention should switch away from an exclusive focus on women selling sexual services to target the men who purchase sex. These data indicate that much of the pressure for these women to provide unprotected sex comes from their clients.

Estimates of HIV infection among injecting drug users in Glasgow, 1985-1990.

OBJECTIVE: To use research and surveillance studies in Glasgow (Scotland, UK) to estimate the number of current injectors infected with HIV, the total number of injectors infected up to the end of 1990 and the recent incidence of infection. DESIGN: (A) Prevalence of injecting drug use was estimated using log-linear modelling. (B) Prevalence of HIV infection was determined from voluntary testing of a community-wide sample of injectors. (C) The number of infected current injectors was predicted by combining the distributions generated by (A) and (B). (D) Data on known HIV-positive injectors were used in conjunction with (C) to forecast the cumulative number of infected injectors. RESULTS: The number of current injectors was estimated to be 9400; the prevalence of HIV infection among 447 injectors recruited to the HIV prevalence study during 1990 was 1.1%. From these data, the number of HIV-positive current injectors in 1990 was estimated to be between 52 and 138. Between 1985 and 1990, 110 known HIV-positive injectors were registered or received treatment in Glasgow for HIV-related diseases; the total number of cases estimated to have occurred during this period was between 110 and 300. The incidence of infection in Glasgow during 1990 was likely to have been low in light of the finding that only one case in the prevalence study had not previously been diagnosed HIV-positive. CONCLUSIONS: Linkage of datasets from a variety of sources and studies has enabled the substantial refinement of estimates of the number of injectors and the proportion infected with HIV in Glasgow up to 1990.

Providing drug injectors with easier access to sterile injecting equipment: a description of a pharmacy based scheme.

In this short paper we describe the operation of a pharmacy-based scheme operating in Glasgow to provide injecting drug users with sterile injecting equipment. The operation of the scheme is described under a number of headings: its physical location, the policy of selling injecting equipment, the return of previously used equipment, counselling and referral, and, the style of working of pharmacy staff. It is shown that while retail pharmacies may be an important point of contact with injecting drug users it should not be assumed that pharmacy staff already possess the requisite skills for working in this area. There is a need for pharmacists' and their staff to be able to draw upon the experience of colleagues working in this area in order to benefit from a pool of common experience. In addition there is a need to provide staff with access to appropriate back-up and support services.

A new method of estimating prevalence of injecting drug use in an urban population: results from a Scottish city.

Using modelling techniques derived from behavioural ecology, unnamed identifier data from a variety of partial samples of injecting drug users [IUDs] were used to estimate the prevalence of this population in Glasgow during 1989. The model yielded an estimate of 9424 [95% confidence interval +/- 2460] which represents a prevalence rate of 15 per 1000 population aged 15-55. The estimated male:female ratio was 2.64:1 and the modal IDU aged 20-24. These figures should facilitate assessment of the service requirements of this group and provide a basis from which the number of IDUs infected with HIV and the number likely to progress to AIDS can be determined. As the methodology required to facilitate reliable prevalence estimates utilizes relatively easy to obtain information it could be repeated in other urban centres where drug injecting is known to occur.

Estimating hidden populations: a new method of calculating the prevalence of drug-injecting and non-injecting female street prostitution.

This paper outlines a new method we have developed for estimating the prevalence of streetworking prostitution and the proportions of female street-working prostitutes who are injecting drug users. This method is based on the capture/recapture approach and involves distinguishing new fieldwork contacts from repeat field work contacts. The size of the overall population can be modelled from records of the increasing ratio of repeat to new fieldwork contacts. The method may have a relevance beyond a concern with prostitution and drug injecting, and may be of value in estimating other hidden populations.

An ethnographic study of HIV-related risk practices among Glasgow rent boys and their clients: report of a pilot study.

This paper provides an early report of a continuing ethnographic study of male prostitution in Glasgow. Pilot work indicates that rent boy activity may be of considerable importance for the spread of HIV infection. Although there is little evidence of an association between rent boy activity and injecting drug use, rent boys may well be implicated in epidemic spread because many (but not all) of them report unsafe sexual practices. Some boys reported that they engaged in unprotected anal sex both actively (insertor) and passively (insertee). Although the majority of the boys' clients were covert bisexuals--married men seeking occasional, anonymous, male sexual contact--a substantial minority of clients were gay-identified.

Adolescents, sex and injecting drug use: risks for HIV infection.

In this paper we present data on the HIV-related risks for adolescents growing up in an area where injecting drug use is prevalent and HIV infection has been identified among local injecting drug users. We report on young peoples' knowledge, attitudes and perceptions of drug use and injectors; HIV and AIDS; sex, safer sex and condom use. These adolescents had an extensive and practically oriented knowledge of illicit drugs and drug injectors. The majority of adolescents contacted had an unsophisticated but approximate understanding of HIV transmission dynamics and how to guard against infection. Our data suggest that many adolescents find issues relating to sex awkward, embarrassing and difficult subjects for discussion. In a final section we consider some of the policy implications of our work focussing in particular on the prevention of injecting, the promotion of condom use, and the necessity of avoiding a focus upon risk groups.
