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.

A minor office: the variable and socially constructed character of death certification in a Scottish city.

Those doctors in a Scottish city who had completed the most death certificates in 1985 were identified, interviewed about their certifying practices, and asked, for comparative purposes, to complete a series of dummy death certificates, based on case summaries. Analysis of the dummy certificates indicated substantial inter-practitioner variations in practice. From the interview data it is clear that the completion of death certificates is a very minor office: for most certifying doctors, death certification is an unsupervised, unreported, invisible, and unconsidered activity. It is argued that doctors who write large numbers of certificates conduct their certifications in Schutz's "world of routine activities" (Schutz 1970). It is this routinized orientation to certification that allows the practitioner to dwell within the "habitus" (Bourdieu 1977) of the medical collectivity but outside a normative order. Death certification may stand as an exemplar of a large number of medical activities, where wide and largely unacknowledged variations in practice occur with each practitioner investing his or her own practices with moral worth. Routinization ensures a moral order in the habitus, but not a normative order.

Ethnostatistics and the AIDS epidemic.

Ethnostatistics is the study of the social practices surrounding the construction and interpretation of statistics. This paper considers certain ethnostatistical aspects of the official statistics on AIDS cases--the monthly updated figures on AIDS cases supplied by the Department of Health and derived from the English and Scottish voluntary reporting schemes. The paper focuses on problems in the classification of cases according to the route of virus transmission, particularly where multiple risk practices may be reported. Some (but not all) classification problems can be avoided by adopting a cross-tabular format of presentation. The data on reported Scottish AIDS cases are re-analysed in order to illustrate such a cross-tabular representation. These data are the basis for a concluding statement on the difficulties in projecting future heterosexual epidemic spread.

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.

Injecting drug use and female street-working prostitution in Glasgow.

There are considerable difficulties associated with calculating the prevalence of covert, illegal and stigmatized activities. This paper outlines new methods we have developed for calculating the prevalence of both drug-injecting street prostitution and non-injecting street prostitution in Glasgow. Our data indicate that Glasgow has a much higher level of injecting drug use than has been reported among prostitutes in other British cities.

Artefact explanations of inequalities in health: an assessment of the evidence.

Artefact explanations seek to account for inequalities in health as a construct of the measurement process. The Black Report believed that the artefact explanation was relatively unimportant in accounting for the persistence of class inequalities in health. This paper reviews the evidence on artefact explanations of class differentials in specific-cause and all-cause mortality data, and also of differentials by occupation, by geography, and by gender. It is concluded that the role of artefact explanations in mortality differentials is larger, more pervasive, and more complex than Black and his colleagues believed.

The effectiveness of one-to-one risk communication interventions in health care: a systematic review.

OBJECTIVES: To assess whether risk-communication interventions are associated with changes in patient knowledge, attitudes, and behaviors, and to identify aspects of these interventions that modify these effects. DESIGN: Systematic review. DATA SOURCES: 96 studies from the period 1985-1996 retrieved by electronic searching of eight databases, hand searching of four journals, contacting key authors, and reference list searching. MAIN OUTCOME MEASURES: The effect size of the principal outcome was identified from each study. Outcomes measuring behavioral change were preferred; if these were not available, knowledge, anxiety, or risk perceptions were used, according to the focus of the study. Data were available to calculate the principal effect sizes for 82 of the studies. ANALYSIS: Meta-regression. RESULTS: The methodologic qualities of the studies varied. Nevertheless, risk-communication interventions generally had positive (beneficial) effects. Interventions addressing treatment choices were associated with larger effects than were those in other contexts, such as prevention or screening. Interventions using individual risk estimates were associated with larger effects than were those using more general risk information. Two design variables were identified as effect modifiers: randomized controlled trials were associated with smaller effects than other designs, and dichotomous outcomes were associated with larger effects than continuous outcomes. CONCLUSIONS: Risk communication interventions may be most productive if they include individual risk estimates in the discussion between professional and patient. Patient decisions about treatment appear more amenable to change by these interventions than attendance for screening or modification of risky behavior.

Reduction in needle sharing among community wide samples of injecting drug users.

Evidence of reduced levels of needle sharing among injecting drug users (IDUs) has largely been confined to IDUs attending needle exchanges or receiving treatment. In this paper we present the results of a serial cross-sectional study of needle sharing conducted in Glasgow using a multisite sampling strategy. Of the estimated 9400 IDUs in the city, 503 were interviewed in 1990 and 535 in 1991. The proportion of IDUs reporting injecting with, or passing on used needles and syringes in the last 6 months fell significantly as did the number of individuals from whom equipment was received or passed on to. The impact of this level of sharing has been limited in terms of HIV transmission; the prevalence of HIV among the 1990 sample was 2.0% and 1.1% for the 1991 sample. However, the fact that third of IDUs in Glasgow continue to inject, even occasionally, with used equipment gives cause for concern in view of the other pathologies known to be associated with poor injecting hygiene.
