Objective: This study examined gender-specific effects of social bonds, network characteristics, and other factors on drug treatment enrollment among Puerto Rican drug users.

Method: Participants (425 women; 1,374 men) were recruited in New York and Puerto Rico in 1998-2003.

Results: Gender differences were found: education (< high school/GED) and having a sex partner who is an injection drug user (IDU) were significantly related to current enrollment in drug treatment (EDT) for women; for men, having an IDU friend (negatively) had a main effect on EDT, and having an IDU friend also had a significant interaction effect with their own injection drug use on EDT.

Biculturality refers to two independent processes of acculturation, one to the host society's culture and another to the culture of origin. This study examined the relationship between biculturality and HIV-related risk behaviors in a sample of injecting and noninjecting Puerto Rican drug users (N = 259), recruited in New York City in 2005-2006. Biculturality was measured by two scales: involvement in (i) American culture (AMBIC) and (ii) Puerto Rican culture Biculturality (PRBIC).

Background: Puerto Rican drug users recruited in NY who previously used drugs in Puerto Rico (PR) have been found to have higher HIV injection and sex-related risk behaviors than those who had not used in PR. This study examined predictors of risk among migrant Puerto Rican drug users. (For the purpose of this paper, the term "migrant" was used to designate Puerto Rican drug users who had used drugs in Puerto Rico and were recruited in New York or New Jersey).

Reducing sex risk behaviors among high-risk injection drug users (IDUs) and crack smokers is a continuing challenge for HIV prevention. Based on a longitudinal study of sexually active Puerto Rican IDUs and crack smokers in New York (n = 573) and Puerto Rico (n = 264), baseline predictors of changes in sex risk (number of unprotected sex acts) at 6- and 36-month follow-up interviews were examined. In New York, predictors of higher sex risk were being younger, having primary partners, having more other sex partners, never exchanging sex, having lower self-efficacy for reducing sex risk behaviors and being HIV-negative, and these predictors were significant at both postbaseline periods.
