Langues : Anglais (eng) Mots-clés : Thésaurus INJECTION ; HEPATITE ; USAGER ; PREVENTION ; VACCINATION ; CONDUITE A RISQUE Descripteurs géographiques ETATS-UNIS Descripteurs internes VHC Résumé : Background Despite CDC recommendations to vaccinate injection drug users (IDUs) against hepatitis A virus (HAV) and hepatitis B virus (HBV) infections, coverage remains low. Vaccination programs convenient to IDUs have not been widely implemented or evaluated. We assessed whether convenience and monetary incentives influenced uptake of free vaccine by 18-30-year-old IDUs in five U.S. cities. Methods IDUs recruited from community settings completed risk behavior self-interviews and testing for antibodies to HAV (anti-HAV) and hepatitis B core antigen (anti-HBc). Vaccine was offered presumptively at pre-test (except in Chicago); on-site availability and incentives for vaccination differed by site, creating a quasi-experimental design. Results Of 3181 participants, anti-HAV and anti-HBc seroprevalence was 19% and 23%, respectively. Although 83% of participants were willing to be vaccinated, only 36% received =1 dose, which varied by site: Baltimore (83%), Seattle (33%), Los Angeles (18%), New York (17%), and Chicago (2%). Participation was highest when vaccine was available immediately on-site and lowest when offered only after receiving results. Monetary incentives may have increased participation when on-site vaccination was not available. Conclusion IDUs were willing to be vaccinated but immediate, on-site availability was critical for uptake. Convenience should be a key consideration in designing strategies to increase vaccine coverage among IDUs. (Review's abstract).

Langues : Anglais (eng) Mots-clés : Thésaurus INJECTION ; VIH ; USAGER ; PREVENTION ; THERAPIE COMPORTEMENTALE ; REDUCTION DES RISQUES ; CONDUITE A RISQUE ; CONTAMINATION Descripteurs internes VHC Résumé : Young injection drug users (IDUs) who are not infected with HIV or hepatitis C virus are at great risk of acquiring one or both of these infections through their sexual or injection behaviors. We describe the development of a behavioral intervention designed to decrease sexual and injection risk behaviors among young IDUs. The intervention was developed through a dynamic and iterative process that involved extensive development activities, focus groups with the target population to pilot individual activities and intervention sessions, and later, pilot testing of the entire intervention. The six-session intervention that emerged from the development process relied on both social-cognitive theories and peer influence models. We also designed a control intervention, trained facilitators to deliver the interventions, and conducted quality assurance of intervention delivery. To better understand intervention trial findings, we asked participants about their intervention experiences and examined potential contamination across arms. Both interventions were delivered with high fidelity and participants in both groups reported positive experiences. More perceived impact was reported for injection risk behaviors than for sexual risk behaviors among participants in the intervention arm. Minimal evidence of contamination was found. Lessons learned can help future researchers to develop stronger interventions for this high-need population. (Review's abstract).

Langues : Anglais (eng) Mots-clés : Thésaurus ADULTE JEUNE ; VIH ; USAGER ; PREVALENCE ; COHORTE Descripteurs internes VHC Résumé : Background New injection drug users (IDUs) are at high risk for blood-borne viral infections. Given U.S. policy to only fund proven-effective HIV prevention interventions, insights into conducting intervention trials among young IDUs are provided here by describing methods and participantsÆ characteristics in the CIDUS III/DUIT study. Methods In 2002-2004, 15-30-year-old IDUs in Baltimore, Chicago, Los Angeles, New York, and Seattle were recruited through community outreach, advertising and coupon-based participant referrals. Baseline interviews assessed sociodemographics, injection, and sexual behaviors. Antibody tests for HIV and hepatitis A, B, and C viruses (HAV, HBV, and HCV) were conducted. IDUs who were HIV and HCV antibody negative at baseline were eligible to participate in a randomized controlled HIV/HCV prevention trial. Follow-up assessments were conducted 3 and 6 months post-intervention. Data were analyzed to identify participant differences at baseline by city, trial enrollment, and trial retention. Results Baseline assessments were completed by 3285 IDUs. Participants were mean age 23.8 years, 69% male, 64% White, 17% Hispanic, and 8% Black. Seroprevalence of HIV, HCV, HBV, and HAV antibodies were 2.9, 34.4, 22.4, and 19.3%, respectively. Of the 2062 (62.7%) baseline participants who were HIV and HCV antibody negative, 859 (41.7%) were randomized. At least one follow-up assessment was completed by 712 (83%) randomized participants. Contextual factors, primarily homelessness, were associated with lower enrollment and retention. Conclusions Recruitment and retention of young-adult IDUs for complex intervention trials is complicated, yet feasible. Risk behaviors among participants enrolling in and completing the trial reflected those eligible to enroll. (Review's abstract).

Langues : Anglais (eng) Mots-clés : Thésaurus INJECTION ; USAGER ; PARTAGE DE SERINGUE ; PAIR ; CONDUITE A RISQUE Descripteurs géographiques ETATS-UNIS Résumé : Objectives This study examined risk factors for receptive syringe sharing (RSS) during illicit drug injection by persons 15-30 years old in five U.S. cities. Methods Participants were recruited through street outreach and respondent-driven referrals in Baltimore, Chicago, Los Angeles, New York, and Seattle between May 2002 and January 2004. Surveys of drug use, sexual behaviors, and correlates were administered through audio computer-assisted self-interviews at baseline and, for the subset of participants who enrolled in an HIV/HCV prevention intervention trial, at 3-months and 6-months post-baseline. The proportions of injections involving RSS at baseline and at follow-up were used as outcomes in multivariate models that adjusted for intervention effects. Results At baseline, 54% of 3128 participants reported RSS in the past 3 months. RSS decreased to 21% at 6-months post-baseline for the combined trial arms. Participants were more likely to report RSS if they perceived that their peers were not against RSS and if they injected with sex partners. Lower levels of perceived risk of infection with HIV (baseline, p < .001) or HCV (follow-up, p < .001) through RSS were also significant predictors of greater RSS. Conclusions Perceived risks, peer influences, and type of injection partner were robust predictors of RSS. Perceived risks and peer influences are particularly amenable to intervention efforts that may prevent RSS in this age group. (Review's abstract).

J. Année de publication : 2008 Article en page(s) : p.221-233 Caractéristiques matérielles : graph., tabl. Langues : Anglais (eng) Mots-clés : Thésaurus ETHNIE ; EVOLUTION ; INJECTION ; VIH ; TYPE D'USAGE ; HEROINE Résumé : Background. Racial/ethnic differences in drug injection prevalence contribute to disparities in HIV infection rates in the US between Whites, Blacks and Hispanics. We examine trends in the demographic characteristics of heroin injection drug users (IDUs) that may impact future HIV rates. Methods. Descriptive analyses were conducted of (1) the national Treatment Episode Data Set for 1992-2004 and of the 2002-2004 baseline data from (2) CIDUS-III, a 5-city study that recruited 3285 young IDUs, and (3) NIHU-HIT, a Chicago study of 647 young noninjecting heroin users. Results. Between 1992 and 2004, heroin was the injected drug most often reported at admission to drug treatment. During this period, the proportion of admissions reporting injection declined 44% among Blacks but only 14% for Whites. The peak age for heroin IDUs in treatment increased 10 years for Blacks while declining over 10 years for Whites. CIDUS-III enrolled about 8 times more White (64%) than Black (8%) young IDUs despite recruiting two-thirds of the sample in cities where Blacks constituted 27-64% of the population. Blacks comprised 53% of noninjecting heroin users in the Chicago NIHU-HIT, but only 2% of Chicago's CIDUS-III sample of heroin IDUs. Among current noninjecting heroin users, Whites were more likely than Blacks to have ever injected (, p < 0.001). Qualitative data supported greater resistance to injection among young Blacks than Whites. Conclusions. Among heroin users, young Blacks are resisting injection while young Whites exhibit the opposite tendency. New research should investigate reasons for this trend and its impact on the HIV epidemic and future service needs. (Review's abstract).
