Risk factors for shooting gallery use among drug injectors in Puerto Rico

Needle sharing is one of the principal risk behaviors leading to HIV transmission among injection drug users (IDUs). Shooting galleries, a social context where IDUs rent, share, and borrow needles, are locations usually found near drug markets. This study, which interviewed 1,700 IDUs from May 1989 to June 1990, assesses sociodemographic characteristics and HIV risk behaviors among shooting gallery users in Puerto Rico. Multivariate analyses showed that shooting gallery use is associated with speedball (a concoction of heroin and cocaine) injection, income from illegal activities and previous drug treatment. Shooting gallery users were more likely to rent, share, and borrow needles, and less likely to always use bleach and water to clean needles. Strategies to reduce shooting gallery use among drug injectors are discussed

HIV/AIDS risk perception, HIV risk behaviors, and HIV seropositivity among injection drug users in Puerto Rico

This paper assesses the factors related to self perception of developing AIDS among a group of 1,568 Puerto Rican injection drug users (IDUs). Incarceration history, years of drug injection, sharing needles, renting and borrowing needles, sharing rinse water or cooker, and having an IDU sex partner yielded a moderate association with HIV/AIDS risk perception. Use of sterile needles, shooting drugs alone, having had previous treatment episodes, and all the variables related to health status were also moderately associated with HIV/AIDS risk perception. A logistic regression model based on backwards elimination procedure, which included statistically significant variables in the bivariate analyses, yielded the variables living with children, sex with an IDU partner, shooting drugs alone, perception of health, having had a sexually transmitted disease, and results of HIV testing as statistically significant (p < 0.05)
