NHBS is a cross-sectional study to investigate HIV behavioral risks among core risk groups in 21 . cities with the highest HIV AIDS prevalence. This analysis examines data from the NHBS data collection cycle with IDU conducted in New York City in 2009. We explored how the recency of migration from Puerto Rico PR to New York City NYC impacts both syringe sharing and unprotected sex among injection drug users IDU currently living in NYC. Methods We used a mixed-methods approach to examine differences in risk between US-born IDU PR IDU who migrated to NYC more than three years ago non-recent migrants and PR IDU who migrated in the last three years recent migrants . Respondent-driven sampling RDS was used to recruit the sample n 514 . In addition qualitative individual and group interviews with recent PR migrants n 12 and community experts n 2 allowed for an in-depth exploration of the IDU migration process and the material and cultural factors behind continued risk behaviors in NYC. Results In multiple logistic regression controlling for confounding factors recent migrants were significantly more likely to report unprotected sexual intercourse with casual or exchange partners adjusted odds ratio AOR 95 confidence intervals CI and receptive syringe sharing AOR 95 CI in the past year compared to US-born IDU. HIV and HCV seroprevalence were highest among non-recent migrants. Qualitative results showed that risky injection practices are partly based on cultural norms acquired while
