HIV risk exposure of injecting drug users in Sydney.

One thousand two hundred and forty-five Sydney injecting drug users (IDUs) were interviewed by questionnaire in 1989 to determine demographic and behavioural characteristics. One-sixth (16.7%) were considered to be at low risk of HIV from either needle sharing or sexual transmission as they had either never shared injecting equipment, or had not shared for years, or cleaned their injecting equipment effectively on 100% of the occasions when they did share; and were either celibate or monogamous or, if they had multiple partners, had not had unsafe sex in the previous 6 months. Over half (50.7%) had either unsafe injecting or sexual behaviour with the remaining third (32.6%) engaging in both unsafe injecting and sexual practises. Women were more at risk from sharing injection equipment than men but men were more at risk from sexual transmission than women. Increasing age was associated with greater likelihood of safer sex but age had no effect on injecting practises. There was no relationship between unsafe injecting and sexual practises. Amphetamine use was associated with low risk injecting practises while heroin use was associated with low risk sexual transmission. These findings indicate appreciable residual risk behaviour sufficient to allow for at least a slow diffusion of HIV among injecting drug users.

Reliability of interview responses of injecting drug users.

We compared 23 injecting drug users (IDUs) who were part of a larger study at retest periods of less than or greater than one month for test-retest reliability of their responses to a detailed questionnaire covering demographics, drug use, HIV risk behavior and attitudes and knowledge about HIV. Data indicated that there was high test-retest reliability for demographic characteristics, and for the social context of drug use for the shorter retest duration.

Explanations for sharing injection equipment in injecting drug users and barriers to safer drug use.

We examined the explanations given by a sample of 1245 injecting drug users in Sydney, Australia for accepting used injection equipment. Factor analysis of these reasons revealed three dimensions of sharing: not caring when withdrawing or intoxicated, unavailability of equipment, and not seeing it as high risk or ease of injecting. The most common reasons given were difficulty in obtaining sterile equipment (73% of cases), the dangers not seeming so important when in withdrawal (40%) and sharing being something done with friends or lovers (31%). Most common reasons for not sharing were related to health issues (91% citing AIDS and 67% hepatitis). These data suggest that interventions target provision of sterile equipment, and education which highlights risk situations such as intoxication and withdrawal.

Predictors of HIV status among injecting drug users and health promotion.

Two consecutive samples one year apart of injecting drug users (n = 754 and n = 345) were collected in Sydney, Australia and analysed for predictors of Human Immunodeficiency Virus (HIV) prevalence. Data indicated that similar variables were associated with HIV infection in both waves of the study. Risks for HIV infection included number of injections in last typical using month, acceptance of used injecting equipment from other injecting drug users (IDUs) who were known to be infected either before or after the sharing occurred, having sex with people known to be infected with HIV, and sexual orientation. It was not possible to determine whether sexual or equipment sharing with known HIV infected people preceded or followed HIV infection. These data confirm that predictors of HIV prevalence in Sydney are similar to those found in overseas studies and that sexual orientation appears to be the most powerful predictor. These data suggest both that sexual contact is an important route of infection in IDUs, and that sexual risks for HIV infection in IDUs need to be emphasised.

Significant relationships and social supports of injecting drug users and their implications for HIV/AIDS services.

Strong social support networks have been associated with positive outcomes for health and well-being throughout the life-cycle. This paper investigates the structural and functional nature of social support networks of 100 injecting drug users (IDUs) in Sydney and the implications for HIV/AIDS services. Using a modified ISEL respondents saw support in terms of its tangibility of people and support, in terms of an appraisal of having friends, and as a self-esteem measure. We found the majority of respondents 'hung around' with other IDUs, lived with other IDUs, and were satisfied with the support they received from their friends. Friends appeared to be a more important source of social support than biological families and if respondents were to become HIV infected they would be more open about their status with friends than family. Where family was involved in support it was likely to be provided by mothers and siblings who were also the family members who knew about the respondent's drug use. There was no relationship between numbers of supports and satisfaction of support, suggesting quality and quantity of support were independent. Non-social supports were conceptualized primarily in terms of medical services.

Changes in equipment sharing in injecting drug users in Sydney 1989-1990.

We investigated levels of equipment sharing in injecting drug users in Sydney, Australia, in two consecutive samples recruited in a non-treatment setting using similar methodology in 1989 (n = 1,245) and 1990 (n = 550). Comparison between the two waves of the study indicated that there were consistent and major reductions in percentage of time used equipment was re-used, and number of people from whom used equipment had been accepted. There was a corresponding significant and major increase in use of sterile injection equipment, obtained more frequently in the second sample from needle and syringe exchanges. The proportion of respondents reporting they had never shared equipment rose significantly. These data suggest that there is a continuing increase in the adoption of safer injecting practices and utilisation of needle and syringe exchanges over time in response to the threat of HIV transmission in injecting drug users.

A comparison of drug use and HIV infection risk behavior between injecting drug users currently in treatment, previously in treatment, and never in treatment.

We compared three groups of injecting drug users in a large cross-sectional study on HIV/AIDS and risk behaviors in Sydney, Australia, to determine what differences existed between those who had never been in treatment (n = 458), had previously been in treatment (n = 387), and were currently in treatment (n = 367). Drug use for those currently in treatment was assessed during the last typical using month before treatment. Those previously and currently in treatment were similar in terms of drug use patterns and HIV risk-related injecting behaviors. Those never in treatment were younger, had a lower level of HIV risk-related injecting behaviors, and reported lower drug use and less involvement in the drug subculture. There was little difference between the three groups on HIV risk-related sexual behaviors. These data suggest that those never in treatment are less dysfunctional and possibly less involved in drug-using careers, whereas there appears to be a close relationship between being previously and currently in treatment.
