This paper discusses the user side of harm reduction, focusing to some extent on the early responses to the HIV/AIDS epidemic in each of four sets of localities-New York City, Rotterdam, Buenos Aires, and sites in Central Asia. Using available qualitative and quantitative information, we present a series of vignettes about user activities in four different localities in behalf of reducing drug-related harm. Some of these activities have been micro-social (small group) activities; others have been conducted by formal organizations of users that the users organized at their own initiative. In spite of the limitations of the methodology, the data suggest that users' activities have helped limit HIV spread. These activities are shaped by broader social contexts, such as the extent to which drug scenes are integrated with broader social networks and the way the political and economic systems impinge on drug users' lives. Drug users are active agents in their own individual and collective behalf, and in helping to protect wider communities. Harm reduction activities and research should take note of and draw upon both the micro-social and formal organizations of users. Finally, both researchers and policy makers should help develop ways to enable and support both micro-social and formally organized action by users.
Cohort studies of young (aged 18-30 years) injecting drug users recruited in 1997-1999 in the Harlem and Lower East Side areas of New York City, New York, were used to assess the incidence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). The authors found that HIV incidence was low at both sites: 0.8/100 person-years at the Harlem site and 0/100 person-years at the Lower East Side site. In contrast, HBV incidence was moderate (12.2/100 person-years) at the Harlem site and high (30.7/100 person-years) at the Lower East Side site. Similarly, HCV incidence was moderate (9.3/100 person-years) at the Harlem site and high (34.0/100 person-years) at the Lower East Side site. Results show that high rates of HBV and HCV transmission do not imply high rates of HIV transmission, even within an area of high HIV seroprevalence.
The objective of the research was to assess the effects of geographic proximity on the utilization of syringe exchange among injection drug users (IDUs) in New York City. Between 1994 and 1996, 805 IDUs were interviewed with a structured questionnaire. Geographic proximity was defined as living within a ten-minute walk. Eighty-one per cent of IDUs who lived close typically used a syringe exchange compared to 59% of those who lived further away. In multiple logistic regression analysis, those who lived close remained (adjusted odds ratio of 2.89; 95% CI 2.06 to 4.06, p = 0.001) more likely to use syringe exchange. Those who lived close were less likely to have engaged in receptive syringe sharing at last injection (adjusted odds ratio = 0.45, 95% CI 0.24 to 0.86, p = 0.015). In conclusion, locating exchange services in areas convenient to large numbers of IDUs may be critical for prevention of HIV infection.
Male IDUs who have sex with men are more likely to engage in higher-risk behaviors and to be HIV infected. Improved intervention approaches for male IDUs who have sex with men are needed.
HIV prevalence and risk behaviors seem to be falling among each racial/ethnic group of drug injectors. Black and Hispanic injectors continue to be more likely to be infected. Declining prevalence among whites poses some risk of politically based decisions to reduce prevention efforts. Overall, these results show that risk reduction can be successful among all racial/ethnic groups of drug injectors and suggest that continued risk reduction programs may be able to attain further declines in infection rates in each group.
