ABSTRACT: Effective on January 1, 2001, New York State enacted the Expanded Syringe Access Demonstration Program (ESAP), which allows syringes to be sold in pharmacies without a prescription or dispensed through doctors, hospitals, and clinics to persons 18 years of age or older and permits the possession of those syringes for the purposes of injecting drugs.
To assess changes in receptive syringe sharing since the inception of the ESAP.
Sociodemographic characteristics and syringe use data regarding the last injection episode were combined from 3 projects (n = 1181) recruiting injection drug users in ongoing studies in Harlem and the Bronx in New York City from January 2001 through June 2003. These data were analyzed as serial cross sections by calendar quarter.
Receptive sharing decreased significantly over time, from 13.4% in the first quarter to 3.6% in the last quarter. Obtaining the last injection syringe from an ESAP source (mostly pharmacies) increased significantly over time, from 7.5% in the first quarter to 25.0% in the last quarter. In multiple logistic regression analysis, variables that were significantly associated with less receptive sharing were syringe exchange and ESAP syringe source as well as time since ESAP inception. Female gender and white race/ethnicity were significantly associated with greater receptive sharing.
The increase in the use of pharmacies and other ESAP syringe sources in this sample has been accompanied by a decline in receptive sharing.

ABSTRACT: Significant differences in HIV-related risk behaviors have been found between Puerto Rican drug users in New York City (NY) and Puerto Rico (PR). An examination of HIV incidence rates and characteristics of seroconverters in each location was undertaken. Baseline and follow-up interviewing and HIV testing were conducted in 1998 to 2002 with seronegative Puerto Rican injection drug users (IDUs) and crack smokers from East Harlem, NY (n = 455) and Bayamón, PR (n = 268). There were a total of 32 seroconverters, 9 in NY and 23 in PR, for seroconversion rates of 0.88/100 person-years at risk (pyr; 95% CI, 0.31-1.45) in NY and 3.37/100 pyr (95% CI, 2.02-4.72) in PR (P < 0.001). In PR, variables significantly related to seroconversion were younger age and using shooting galleries. Being in methadone treatment was protective against seroconversion. In NY, crack use was significantly related to seroconversion. The higher seroconversion rate found in PR indicates a need to enhance HIV prevention efforts, including increasing methadone treatment and access to sterile syringes. The need to address sexual risk behaviors in both locations was also indicated. Resources focusing on reducing HIV transmission in the Caribbean should include efforts to target the drug use-HIV epidemic in PR.

ABSTRACT: The PRECEDE model for health promotion proposes three types of influences on health behaviors: Predisposing, Enabling, and Reinforcing factors. This model was used to examine a range of influences on HIV risk behaviors (sharing syringes and other injection-related paraphernalia) among Puerto Rican injection drug users (IDUs). A total of 698 IDUs were interviewed (438 in East Harlem, New York, and 260 in Bayamón, Puerto Rico). Both types of risk behaviors were more prevalent in Puerto Rico. Similarities in influences on syringe sharing behaviors were found in the two sites and included self-efficacy (for reducing injection-related sharing) and norms. Influences on the sharing of other injection-related paraphernalia were primarily Enabling factors in both communities, and purchasing drugs with others was the strongest predictor of paraphernalia sharing. The need to address risks associated with joint drug purchasing in both locations and to enhance efforts to reduce risks among IDUs in Puerto Rico is indicated.

ABSTRACT: We compared injection-related HIV risk behaviors of Puerto Rican current injection drug users (IDUs) living in New York City and in Puerto Rico who also had injected in the other location with those who had not.
We recruited Puerto Rican IDUs in New York City (n = 561) and in Puerto Rico (n = 312). Of the former, 39% were "newcomers," having previously injected in Puerto Rico; of the latter, 14% were "returnees," having previously injected in New York. We compared risk behaviors within each sample between those with and without experience injecting in the other location.
Newcomers reported higher levels of risk behaviors than other New York IDUs. Newcomer status (adjusted odds ratio [OR] = 1.62) and homelessness (adjusted OR = 2.52) were significant predictors of "shooting gallery" use; newcomer status also predicted paraphernalia sharing (adjusted OR = 1.67). Returnee status was not related to these variables.
Intervention services are needed that target mobile populations who are coming from an environment of high-risk behavior to one of low-risk behavior.
