Abstract
Objective. To examine hepatitis C virus (HCV) seroprevalence among injection drug users in 4 US cities from 1994 through 2004. Methods. Demographic characteristics, behaviors, and prevalence of HCV antibody among 5088 injection drug users aged 18-40 years from Baltimore, Maryland; Chicago, Illinois; Los Angeles, California; and New York, New York, enrolled in 3 related studies - Collaborative Injection Drug User Study (CIDUS) I (1994-1996), CIDUS II (1997-1999), and CIDUS III/Drug User Intervention Trial (2002-2004) - were compared using the χ2 and Mantel-Haenszel tests of significance. Trends over time were assessed by logistic regression. Results. Prevalence of HCV infection was 65%, 35%, and 35% in CIDUS I, CIDUS II, and CIDUS III, respectively. The adjusted prevalence odds ratio (OR) of being HCV antibody positive increased with the number of years of injection drug use (OR, 1.93 [95% confidence interval {CI}, 1.68-2.21] for each year of injecting within the first 2 years; OR, 1.09 [95% CI, 1.07-1.11] for each year of injecting beyond the first 2 years). Significant decreases were observed in the prevalence of HCV antibody between CIDUS I and CIDUS III in Baltimore (OR, 0.30; 95% CI, 0.20-0.43) and Los Angeles (OR, 0.17; 95% CI, 0.09-0.31) and among people of races other than black in Chicago (OR, 0.12; 95% CI, 0.08-0.17). No decrease in prevalence was seen in New York (OR, 1.04; 95% CI, 0.69-1.58) or among blacks in Chicago (OR, 0.55; 95% CI, 0.16-1.90). Conclusion. Although regional differences exist, our data suggest that the incidence of HCV infection among injection drug users in the United States decreased from 1994 through 2004.

Abstract
Negative public reactions to emerging infectious diseases can adversely affect population health. We assessed whether social support was associated with knowledge of, worry about, and attitudes towards AIDS and severe acute respiratory syndrome. Our findings suggest that social support may be central to our understanding of public responses to emerging infectious diseases.

Abstract
Abstract
Background. The hepatitis C virus (HCV) is hyper-endemic in injecting drug users. There is also excess HCV among non-injection drug users who smoke, snort, or sniff heroin, cocaine, crack, or methamphetamine. Methods. To summarize the research literature on HCV in drug users and identify gaps in knowledge, we conducted a synthesis of the relevant research carried out between 1989 and 2006. Using rigorous search methods, we identified and extracted data from published and unpublished reports of HCV among drug users. We designed a quality assurance system to ensure accuracy and consistency in all phases of the project. We also created a set of items to assess study design quality in each of the reports we included. Results. We identified 629 reports containing HCV prevalence rates, incidence rates and/or genotype distribution among injecting or non-injecting drug user populations published between January 1989 and December 2006. The majority of reports were from Western Europe (41%), North America (26%), Asia (11%) and Australia/New Zealand (10%). We also identified reports from Eastern Europe, South America, the Middle East, and the Caribbean. The number of publications reporting HCV rates in drug users increased dramatically between 1989 and 2006 to 27-52 reports per year after 1998. Conclusion. The data collection and quality assurance phases of the HCV Synthesis Project have been completed. Recommendations for future research on HCV in drug users have come out of our data collection phase. Future research reports can enhance their contributions to our understanding of HCV etiology by clearly defining their drug user participants with respect to type of drug and route of administration. Further, the use of standard reporting methods for risk factors would enable data to be combined across a larger set of studies; this is especially important for HCV seroconversion studies which suffer from small sample sizes and low power to examine risk factors.

Abstract
OBJECTIVE: To compare HIV prevalence among injecting and non-injecting heroin and cocaine users in New York City. As HIV is efficiently transmitted through the sharing of drug-injecting equipment, HIV infection has historically been higher among injecting drug users. DESIGN: Two separate cross-sectional surveys, both with HIV counseling and testing and drug use and HIV risk behavior questionnaires. METHODS: Injecting and non-injecting heroin and cocaine users recruited at detoxification and methadone maintenance treatment from 2001-2004 (n = 2121) and recruited through respondent-driven sampling from a research storefront in 2004 (n = 448). RESULTS: In both studies, HIV prevalence was nearly identical among current injectors (injected in the last 6 months) and heroin and cocaine users who had never injected: 13% [95% confidence interval (CI), 12-15%] among current injectors and 12% (95% CI, 9-16%) among never-injectors in the drug treatment program study, and 15% (95% CI, 11-19%) among current injectors and 17% (95% CI, 12-21%) among never injectors in the respondent driven sampling storefront study. The 95% CIs overlapped in all gender and race/ethnicity subgroup comparisons of HIV prevalence in both studies. CONCLUSIONS: The very large HIV epidemic among drug users in New York City appears to be entering a new phase, in which sexual transmission is of increasing importance. Additional prevention programs are needed to address this transition.

Abstract
Abstract
Drug treatment staff are uniquely situated to support their clients' HCV related needs, and those with greater self efficacy to do so are more likely to provide this support. Using data collected from staff (N = 140) in 6 drug treatment programs in New York City, we determined the correlates of this self efficacy. Results indicate that medically credentialed staff and staff with more hepatitis C knowledge have greater self efficacy to support their clients' HCV related needs. There was no relationship between this self efficacy and the staff member's own HCV infection or that of a close relative. Efforts should focus on increasing staff's HCV knowledge in order to increase their confidence in providing HCV related support to their clients.

Abstract
Abstract
Background. In spite of the disproportionate prevalence of hepatitis C virus (HCV) infection among drug users, many remain uninformed or misinformed about the virus. Drug treatment programs are important sites of opportunity for providing HCV education to their patients, and many programs do, in fact, offer this education in a variety of formats. Little is known, however, about the level of HCV knowledge among drug treatment program patients, and the extent to which they utilize their programs' HCV education services. Methods. Using data collected from patients (N = 280) in 14 U.S. drug treatment programs, we compared patients who reported that they never injected drugs (NIDUs) with past or current drug injectors (IDUs) concerning their knowledge about HCV, whether they used HCV education opportunities at their programs, and the facilitators and barriers to doing so. All of the programs were participating in a research project that was developing, implementing, and evaluating a staff training to provide HCV support to patients. Results. Although IDUs scored higher on an HCV knowledge assessment than NIDUs, there were many gaps in HCV knowledge among both groups of patients. To address these knowledge gaps, all of the programs offered at least one form of HCV education: all offered 1:1 sessions with staff, 12 of the programs offered HCV education in a group format, and 11 of the programs offered this education through pamphlets/books. Only 60% of all of the participating patients used any of their programs' HCV education services, but those who did avail themselves of these HCV education opportunities generally assessed them positively. In all, many patients were unaware that HCV education was offered at their programs through individual sessions with staff, group meetings, and books/pamphlets, (42%, 49%, and 46% of the patients, respectively), and 22% were unaware that any HCV education opportunities existed. Conclusion. Efforts especially need to focus on ensuring that all drug treatment program patients are made aware of and encouraged to use HCV education services at their programs.

Abstract
Abstract
CONTEXT: The US Centers for Disease Control and Prevention (CDC) strongly recommend comprehensive risk counceling and services for people living with HIV (PLH); yet, there are no evidence-based counseling protocols. OBJECTIVE: To examine the effect of a 15-session, individually delivered, cognitive behavioral intervention on a diverse sample of PLH at risk of transmitting to others. DESIGN: This was a multisite, 2-group, randomized, controlled trial. PARTICIPANTS: Nine hundred thirty-six HIV-infected participants considered to be at risk of transmitting HIV of 3818 persons screened were randomized into the trial. Participants were recruited in Los Angeles, Milwaukee, New York, and San Francisco. INTERVENTION: Fifteen 90-minute individually delivered intervention sessions were divided into 3 modules: stress, coping, and adjustment; safer behaviors; and health behaviors. The control group received no intervention until the trial was completed. Both groups completed follow-up assessments at 5, 10, 15, 20, and 25 months after randomization. MAIN OUTCOME MEASURE: Transmission risk, as measured by the number of unprotected sexual risk acts with persons of HIV-negative or unknown status, was the main outcome measure. RESULTS: Overall, a significance difference in mean transmission risk acts was shown between the intervention and control arms over 5 to 25 months (χ = 16.0, degrees of freedom = 5; P = 0.007). The greatest reduction occurred at the 20-month follow-up, with a 36% reduction in the intervention group compared with the control group. CONCLUSION: Cognitive behavioral intervention programs can effectively reduce the potential of HIV transmission to others among PLH who report significant transmission risk behavior.

Abstract
Early acquisition of hepatitis C virus (HCV) infection appears to affect a substantial proportion of injection drug users (IDUs)-between 20 percent and 90 percent. Analysing the range of HCV prevalence estimates in new injectors may help identify factors that can be modified to reduce HCV transmission. The HCV Synthesis Project is a meta-analysis of studies of HCV epidemiology and prevention in drug users worldwide. In this preliminary analysis, we examined data from 127 studies of IDUs that reported HCV prevalence in relation to age or year since onset of drug injection, analysing heterogeneity and calculating summary statistics where appropriate. Six studies reported gender-specific HCV prevalence rates among young or new injectors; the group mean prevalence was 47 percent for men and 44 percent for women (NS). Group mean age for HCV-negatives was 24.7 years (range 24-28) and 26.1 years (range 21-31) for HCV-positives (n = 8 studies). Data were examined from 13 studies that compared HCV prevalence among young injectors to older injectors using 5-year age categories; substantial variation was present within these categories such that measures of central tendency were not calculated. Similarly, among studies reporting HCV prevalence among IDUs in relation to 1-year intervals of duration of injection (<1 year, <2 years, and <3 years), considerable variability was observed. Notably, there were studies in each category that reported prevalence of 70 percent or higher among recent-onset drug injectors. Our findings confirm previous studies reporting high risk of acquiring HCV shortly after onset of injection; thus, HCV prevention programmes must emphasize methods to reach new injectors. Future research should (1) report data on time to infection in depth, (2) provide detailed information on study methodology, and (3) characterize the research setting with respect to underlying factors that affect injection practices and networks. This will permit synthesis of a greater number of studies and may lead to the identification of factors that impede HCV transmission.

Abstract
OBJECTIVE: To examine the relationship between herpes simplex virus 2 (HSV-2) seroprevalence and human immunodeficiency virus (HIV) seroprevalence among noninjecting heroin and cocaine users in New York City. METHODS: Four hundred sixty-two noninjecting cocaine and heroin users were recruited from a drug detoxification program in New York City. Smoking crack cocaine, intranasal use of heroin, and intranasal use of cocaine were the most common types of drug use. A structured interview was administered and a serum sample was collected for HIV and HSV testing. RESULTS: HIV prevalence was 19% (95% CI 15%-22%) and HSV-2 seroprevalence was 60% (95% CI 55%-64%). The adjusted risk ratio for the association between HSV-2 and HIV was 1.9 (95% CI 1.21%-2.98%). The relationship between HSV-2 and HIV was particularly strong among females, among whom 86% were HSV-2 seropositive, 23% were HIV seropositive, and all HIV seropositives were also HSV-2 seropositive. CONCLUSIONS: HSV-2 appears to be an important factor in sexual transmission of HIV among noninjecting cocaine and heroin users in New York City, especially among females. The estimated population attributable risk for HIV infection attributable to HSV-2 infection in this sample was 38%. Programs to manage HSV-2 infection should be developed as part of comprehensive HIV prevention for noninjecting drug users.

Abstract
Abstract
A pattern of serious injection drug user (IDU) driven HIV epidemics in Asia, with emerging evidence of generalization through heterosexual transmission, indicates the need for interventions focusing on both drug- and sex-related risk reduction. In a cross-border HIV prevention project for IDUs in northern Vietnam and southern China, peer educators disseminated risk reduction information to IDUs in the community and provided 20,000-25,000 sterile needles/syringes and 4,000-6,000 condoms per month. Since implementation of these interventions, the frequency of both injecting and sexual risk behaviours fell significantly, HIV prevalence among IDUs declined or stabilized, and HIV incidence dropped. There is official support for harm reduction interventions in both countries but this appears precarious in view of persistently powerful political and financial support for a law enforcement approach. Moreover, the simultaneous pursuit of inconsistent policies can have negative effects on the implementation of interventions. A harmonized and consistent policy environment is needed. Most of the evidence for efficacy of community-based HIV prevention comes from the developed world, but well-designed evaluations of such interventions in Asia and elsewhere in the developing world would have a better chance to influence policy decisions there. A synergistic approach to research, policy development, and service delivery is best calculated to achieve positive results in the struggle against HIV/AIDS in developing countries.

Abstract
Abstract
Background. A number of studies suggest females may be more likely to engage in injection and sex risk behavior than males. Most data on gender differences come from industrialized countries, so data are needed in developing countries to determine how well gender differences generalize to these understudied regions. Methods. Between 1999 and 2003, 2512 male and 672 female current injection drug users (IDUs) were surveyed in ten sites in developing countries around the world (Nairobi, Beijing, Hanoi, Kharkiv, Minsk, St. Petersburg, Bogotá, Gran Rosario, Rio, and Santos). The survey included a variety of questions about demographics, injecting practices and sexual behavior. Results. Females were more likely to engage in risk behaviors in the context of a sexual relationship with a primary partner while males were more likely to engage in risk behaviors in the context of close friendships and casual sexual relationships. After controlling for injection frequency, and years injecting, these gender differences were fairly consistent across sites. Conclusion. Gender differences in risk depend on the relational contexts in which risk behaviors occur. The fact that female and male risk behavior often occurs in different relational contexts suggests that different kinds of prevention interventions which are sensitive to these contexts may be necessary.

Abstract
This study examined the effect of syringe exchange program setting on the injection practices, health status, and health service utilization patterns of injection drug users (IDUs) recruited from a public urban hospital. One hundred sixty-six participants were randomized to either community- or hospital-based syringe exchange services. Poisson regression models were used to compare service utilization between groups. In both conditions, risky drug use practices decreased, and physical health functioning improved over time. Hospital-based syringe exchange program (SEP) attendees had 83% more inpatient admissions (p < .0001) and 22% more ambulatory care visits (p < .0001) than those assigned to the community-based SEP condition. Syringe exchange services that are integrated into public hospital settings may serve as a valuable strategy to engage hard to reach IDU populations in behavioral interventions designed to reduce HIV risk transmission behaviors and increase access to, or engagement in, the use of secondary and tertiary preventive medical care.

Abstract
We examine injecting and sexual risk correlates of hepatitis B (HBV) and hepatitis C (HCV) seroprevalence among new injecting drug users (IDUs) (age 18-30 years, injecting ≤6 years). Participants were interviewed/serotested (HIVab, HBVcAb, HCVab) in New York City, February 1999-February 2003. Gender-stratified, multivariate logistic regression was conducted. Participants (N = 259) were: 68% male; 81% white. Women were more likely to test HCV seropositive (42% versus 27%) and men HBV seropositive (24% versus 12%); HIV seroprevalence was low (3%). Among both men and women, HBV seropositivity was associated with ever selling sex, and HCV seropositivity with ever having had infected (HIV, HBV or HCV) sex partners (among those ever sharing injecting equipment). Among women only, HBV seropositivity was associated with ever having had infected sex partners (regardless of ever sharing injecting equipment), and HCV seropositivity with ≥300 lifetime drug injections. Among men only, HCV seropositivity was associated with ≥40 lifetime number of sex partners (among those never sharing injecting equipment). In this new IDU sample, HBV and HCV seroprevalence differed by gender and were considerably higher than HIV seroprevalence. Early interventions, targeting injecting and sexual risks and including HBV vaccination, are needed among new IDUs to prevent HBV, HCV and, potentially, HIV epidemics.

Abstract
This systematic review examined the evidence on the prevalence of the Hepatitis C Virus (HCV) in non-injecting drug users (NIDUs) who sniff, smoke or snort drugs such as heroin, cocaine, crack or methamphetamine. The search included studies published from January 1989 to January 2006. Twenty-eight eligible studies were identified and the prevalence of HCV in these NIDU populations ranged from 2.3 to 35.3%. There was substantial variation in study focus and in the quality of the NIDU data presented in the studies. The results of our systematic review suggested that there are important gaps in the research of HCV in NIDUs. We identified a problem of study focus; much of the research did not aim to study HCV in users of non-injection drugs. Instead, NIDUs were typically included as a secondary research concern, with a principal focus on the problem of transmission of HCV in IDU populations. Despite methodological issues, HCV prevalence in this population is much higher than in a non-drug using population, even though some IDUs might have inadvertently been included in the NIDU samples. These studies point to a real problem of HCV in NIDU populations, but the causal pathway to infection remains unclear.

Abstract
Aims: A prior study concluded that drug treatment coverage, defined as the percentage of injection drug users in drug treatment, varied from 1 percent to 39 percent (median 9 percent) in 96 metropolitan statistical areas (MSAs) in the United States. Here, we determine which metropolitan area characteristics are associated with drug treatment coverage. Methods: We conducted secondary analysis of official data, including the number of injection drug users in treatment and other variables, for 94 large US MSAs. We estimated the number of injection drug users in these metropolitan areas using previously described methods. We used lagged cross-sectional analyses where the independent variables, chosen on the basis of a Theory of Community Action, preceded the dependent variable (drug treatment coverage) in time. Predictors were determined using ordinary least squares multiple regression and confirmed with robust regression. Results: Independent predictors of higher drug treatment coverage for injectors were: presence of organisations that support treatment (unstandardized beta = 1.64; 95 percent CI .59 to 2.69); education expenditures per capita in the MSA (unstandardized beta = .12; 95 percent CI -.34 to 2.69); lower percentage of drug users in treatment who are non-injection drug users (unstandardized beta = -0.18; 95 percent CI -0.24 to -0.12); higher percentage of the population who are non-Hispanic White (unstandardized beta = .14; 95 percent CI .08 to .20); lower per capita long-term debt of governments in the metropolitan area (unstandardized beta = -0.93; 95 percent CI -1.51 to -0.35). Conclusions: In conditions of scarce treatment coverage for drug injectors, an indicator of epidemiologic need (the per capita extent of AIDS among injection drug users) does not predict treatment coverage, and competition for treatment slots by non-injectors may reduce injectors' access to treatment. Metropolitan finances limit treatment coverage. Political variables (racial structures, the presence of organisations that support drug treatment, and budget priorities) may be important determinants of treatment coverage for injectors. Although confidence in these results would be higher if we had used a longitudinal design, these results suggest that further research and action that address structural, political, and other barriers to treatment expansion are sorely needed.

Abstract
OBJECTIVES: To assess an HIV prevention programme for injecting drug users (IDU) in the crossborder area between China and Vietnam. DESIGN: Serial cross-sectional surveys (0, 6, 12, 18, 24 and 36 months) of community-recruited current IDU. METHODS: The project included peer educator outreach and the large-scale distribution of sterile injection equipment. Serial cross-sectional surveys with HIV testing of community recruited IDU were conducted at baseline (before implementation) and 6, 12, 18, 24 and 36 months post-baseline. HIV prevalence and estimated HIV incidence among new injectors (individuals injecting drugs for < 3 years) in each survey wave were the primary outcome measures. RESULTS: The percentages of new injectors among all subjects declined across each survey waves in both Ning Ming and Lang Son. HIV prevalence and estimated incidence fell by approximately half at the 24-month survey and by approximately three quarters at the 36-month survey in both areas (all P < 0.01). CONCLUSION: The implementation of large-scale outreach and syringe access programmes was followed by substantial reductions in HIV infection among new injectors, with no evidence of any increase in individuals beginning to inject drugs. This project may serve as a model for large-scale HIV prevention programming for IDU in China, Vietnam, and other developing/transitional countries.

Abstract
This study assessed relationships between residual risk behavior (risk behavior among persons participating in effective HIV prevention programs) and HIV infection. Structured interviews and HIV tests were obtained from participants in six large U.S. syringe exchange programs. Program characteristics were obtained through interviews with the directors. Findings indicated that injection risk behaviors varied significantly across the six programs - from 10% to 27% of the participants at each program reported receptive sharing of needles and syringes in the 30 days prior to the interview. HIV prevalence ranged from 2.5% to 22.2% across the six programs. HIV prevalence among new injectors was strongly related to HIV prevalence among long-term injectors across the programs (r = .869). There was a consistent pattern of negative relationships between injection risk behaviors and HIV infection across the six programs (higher rates of risk behavior at a program associated with lower HIV infection). As a result, appropriate evaluation of HIV prevention programs may require not only information on continuing risk behavior and HIV infection among program participants but also historical information on the epidemiology of HIV in the local community.

Abstract
Background. Many heroin users do not inject drugs but may still be at risk of infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), via sexual or other noninjection-related activity. Methods. Noninjecting heroin users (NIUs) in New York City who were recruited and prospectively followed during March 1996-February 2003 were tested for anti-HIV, anti-hepatitis B core antigen, and anti-HCV and were interviewed about their sexual and other noninjecting risk. A seroconversion is represented by the first positive test result after the last negative test result. Hazard ratios (HRs) (P < .05) were estimated by use of Cox proportional hazards regression. Results. Of 253 HIV-negative participants, 2 seroconverted (0.29/100 person-years at risk [pyar]); of 184 HBV-negative participants, 16 (3.3/100 pyar); and, of 219 HCV-negative participants, 16 (2.7/100 pyar). Independent predictors of seroconversion were, for HBV, being a female who engages in unprotected receptive anal sex (HR, 6.8), having short-term sex partners (HR, 6.2), and being a male with male sex partners (HR, 5.7); for HCV, being a male who receives money/drugs for sex (HR, 5.6) and sharing noninjecting crack-use equipment (HR, 4.5). Conclusions. NIUs are at considerable risk of HBV infection via high-risk sex; and, for HCV, via high-risk sexual activity and the sharing of noninjecting crack-use equipment. Interventions in NIUs must seek to reduce high-risk sexual activity and the sharing of noninjecting drug-use equipment.

Abstract
Community activism can be important in shaping public health policies. For example, political pressure and direct action from grassroots activists have been central to the formation of syringe exchange programs (SEPs) in the United States. We explored why SEPs are present in some localities but not others, hypothesizing that programs are unevenly distributed across geographic areas as a result of political, socioeconomic, and organizational characteristics of localities, including needs, resources, and local opposition. We examined the effects of these factors on whether SEPs were present in different US metropolitan statistical areas in 2000. Predictors of the presence of an SEP included percentage of the population with a college education, the existence of local AIDS Coalition to Unleash Power (ACT UP) chapters, and the percentage of men who have sex with men in the population. Need was not a predictor.

Abstract
Aims: To characterize heroin and cocaine users in New York City who have changed from injection to non-injection drug administration and to identify factors associated with long-term non-injection use. Design: Two cross-sectional studies of heroin and cocaine users in New York City. Settings and participants: New admissions were recruited at drug abuse treatment programs (2000-04) and respondent-driven sampling was used to recruit drug users from the community (2004). Both injecting and non-injecting drug users participated in each study. 'Former injectors' were defined operationally as people who had used heroin and/or cocaine in the 6 months prior to the interview and who had injected illicit drugs in the past, but whose most recent injection was more than 6 months before the study interview. 'Current' injectors were defined as people who had injected heroin and/or cocaine in the 6 months prior to the interview. Measurements: A structured interview on drug use history was administered, and a serum sample was collected and tested for the human immunodeficiency virus (HIV). Findings: A total of 104 former injectors was recruited for the drug abuse treatment program study, and 229 current injectors were recruited for the community recruitment study; 160 former injectors and 1731 current injectors were recruited from the drug abuse treatment study. Compared with the current injectors, former injectors were older and more likely to be African American. The former injectors reported long intervals since their most recent injection, a mean of 8 years in the drug abuse treatment program study and a mean of 12 years in the community recruitment study. The most common reasons for stopping injection drug use included concerns about health, social stigmatization and self-image, and preference for intranasal use as a route of drug administration. The results were highly consistent across the two studies. Conclusions: The transition from injection to non-injection use appears to be relatively stable behavior change for many former injectors, who report a decade or more without injecting. Developing a greater understanding of the transition from injection to stable non-injection drug use may provide insights into the natural histories of drug use and addiction.

Abstract
Objective: To assess variation in injection risk behavior among unstably housed/homeless injecting drug users (IDUs) across programs in a national sample of US syringe exchange programs. Methods: About 23 syringe exchange programs were selected through stratified random sampling of moderate to very large US syringe exchange programs operating in 2001-2005. Subjects at each program were randomly sampled. Risk behavior interviews were collected using audio-computer assisted self-interviewing (A-CASI). "Unstable housing/homelessness" was operationally defined as having lived "on the street or in a shanty" or "living in a shelter or single room occupancy hotel (SRO)" at any time in the 6 months prior to the interview. "Receptive sharing" was operationally defined as having injected with a needle or syringe that "had been used by someone else" in the 30 days prior to the interview. Six very large and nine moderate-to-large programs had at least 50 subjects who reported unstable housing, and these 15 programs were used in the analyses. Results: There was considerable variation among the 15 programs in the percentages of unstably housed participants (range from 35 to 74%, P < 0.0001), and in the percentages of unstably housed participants who reported receptive sharing (range from 8 to 52%, P < 0.0001). At each of the 15 programs, unstably housed exchange participants were approximately twice as likely to report receptive sharing than were stably housed participants. The weighted mean odds ratio was 2.02, 95% confidence interval, 1.68-2.41 (random effects model) and there was no statistically significant variation in these odds ratios. Across the 15 programs, receptive sharing among unstably housed participants was highly correlated with receptive sharing among stably housed participants (r = 0.95, P < 0.001, 90% of variance among unstably housed "explained" by variance among stably housed). Conclusions: The programs clearly differ in the extent to which they are attracting unstably housed IDUs as participants. The consistency of more frequent injection risk behavior among unstably housed exchange participants and the lack of significant variation in the odds ratios for increased injection risk suggests that none of the programs were "better" or "worse" at reducing injection risk behavior among unstably housed participants. Reduction in injecting risk behavior among syringe exchange participants may require greater efforts to provide stable housing or the development of dramatically new interventions to reduce injecting risk behavior among IDUs with persistent unstable housing.

Abstract
Abstract
Prevention of heterosexual transmission of HIV between and from drug users is important for controlling the local and global HIV heterosexual epidemic. Sex risk reduction interventions and health-related interventions are important for reducing the sex risk behaviors of drug users. Sex risk reduction interventions address individual-level, peer-level, and structural-level determinants of risk reduction. Health-related interventions include HIV counseling and testing, prevention and treatment of sexually transmitted diseases, and delivery of highly active antiretroviral therapy. It is important to adapt effective interventions implemented in resource-rich countries to the realities of the resource-constrained settings and to address relevant contextual factors.

Abstract
We examined the diffusion of the D.A.R.E program to reduce use of illicit drugs among school-aged children and youths and the diffusion of syringe exchange programs to reduce HIV transmission among injection drug users. The D.A.R.E program was diffused widely in the United States despite a lack of evidence for its effectiveness; there has been limited diffusion of syringe exchange in the United States, despite extensive scientific evidence for its effectiveness. Multiple possible associations between diffusion and evidence of effectiveness exist, from widespread diffusion without evidence of effectiveness to limited diffusion with strong evidence of effectiveness. The decision theory concepts of framing and loss aversion may be useful for further research on the diffusion of public health innovations.
