    ABSTRACT: Migration to the United States has emerged as a risk factor for HIV and other STIs among Latino men. Because many Latino migrant men leave their social support and sexual partners behind, they are at an increased risk for engaging in high risk behavior. 37 male, seed egos from a previous study were enrolled and asked to recruit their sex and drug sharing alters. Sexual and drug networks of LMM were recruited via respondent driven sampling and were surveyed on socio demographic information, sex and drug behaviors, network members, and their attributes. Participants were screened for HIV, syphilis, Chlamydia and gonorrhea. Of the 81 enrolled participants, 81.5% (n=66) were men. 291 (191 unique) network members were named, of which 50.2% were sexual contacts, 42.6% were drug contacts, and 7.2% were both drug and sex contacts. 1 participant tested positive for syphilis. Drug users had lower mean (more sensation seeking) score (1.42 vs. 2.08; p .02). Analysis of the sexual networks of the drug and non-drug users' networks reveal high interconnectedness among the drug users, with less connectedness among the non-drug users. The comparison of the sexual networks indicates that the potential for disease spread if introduced into the network is greater among the drug users. Future research in this population should obtaining a better understanding of the network itself through increasing the number of network members enrolled, while potential interventions should focus on promoting family togetherness and cohesion into the receiving society.

    ABSTRACT: High rates of sex and drug risk behaviors have been documented among Latino migrant men in the US. Whether these behaviors were established in the migrants' home countries or were adopted in the US has not been described and has implications for prevention strategies. Quarterly surveys were conducted to gather information on selected sex and drug risk practices of Latino migrant men who arrived in New Orleans after Hurricane Katrina seeking work. Both kappa scores and McNemar's tests were performed to determine if practice of these behaviors in home country was similar to practice post-emigration to the US. Female sex worker (FSW) patronage, same sex encounters (MSM), and crack cocaine use was more likely to occur post- rather than pre-emigration. Of those who ever engaged in these selected behaviors, most adopted the behavior in the US (i.e., 75.8 % of FSW patrons, 72.7 % of MSM participants, and 85.7 % of crack cocaine users), with the exception of binge drinking (26.8 %). Men who were living with a family member were less likely to adopt FSW patronage OR = 0.27, CI = 0.10-0.76, whereas men who earned >$465 per week were more likely to adopt crack cocaine use OR = 6.29 CI = 1.29, 30.57. Interventions that facilitate the maintenance of family cohesion and provide strategies for financial management may be useful for reducing sex and drug risk among newly arrived migrants.

    ABSTRACT: Background Migration and mobility have been associated with higher drug and sex risk behaviour. Whether this increased risk is a result of the characteristics of mobile persons or environmental influences in a receiving community has not been well elucidated. The purpose of this analysis was to determine if risk behaviour was a continuation of sending country practices or if it was adopted in the new receiving environment (ie, New Orleans). Methods A cohort of Latino migrant men (n=93) were interviewed at baseline, 3 and 6-month visits and asked about past month behaviour. At a subsequent visit, they were also asked about behaviours in their sending country. All interviews were conducted in Spanish by trained staff. Four behaviours were examined: patronage of a female sex worker (FSW), sex with a man (MSM), binge drinking, and crack cocaine use. Cross-tabulations and McNemar tests were performed. Results At baseline, the men were mostly Honduran (71.0%), migrated directly to New Orleans from their country of origin (62.0%), were single (50.5%) with a median age of 28 (range 18−50) and a median of 6 years of schooling. The percentage of men reporting patronage of FSW, MSM and crack cocaine use was significantly higher in New Orleans than in the sending country, and high proportion of those reporting the behaviours in New Orleans, did not practice these behaviours in the sending country. When comparing sending country to New Orleans behaviour in order to examine discrepancies for behaviours, all but binge drinking were significantly different (p<0.04) with adoption of the behaviour in New Orleans accounting for >85% of the discrepancy see Abstract P1-S2.75 Table 1. Conclusion Rates of these four risky behaviours were high and, with the exception of binge drinking, were largely behaviours adopted in the USA Newly arrived migrant men are a group at high risk for sex and drug related STI/HIV. Interventions to prevent transmission in this vulnerable, difficult-to-access and highly mobile population are greatly needed.
