Background: Latinx men are disproportionately impacted by HIV. Research often looks at Latinx people as a heterogeneous population. This paper describes baseline characteristics and barriers to HIV care among Mexican born men enrolled in an HIV care engagement intervention at a public health clinic in Chicago. Methods: Survey and medical chart data were collected. Results: 66 Mexican born men enrolled in the project. Over half (60%) were newly diagnosed; 40% were reengaging in care or establishing care for the first time. Participants reported significant pre and postmigration concerns including poverty, social stigma, late entry to care, and concurrent health concerns, including 47% screening positive for depression. Barriers to care and mental health concerns were significantly related to Stage 3 HIV. Discussion: More prevention and intervention research is needed to ameliorate the negative socioeconomic and health ramifications of immigration and bolster mental and sexual health, reduce HIV transmission, and increase testing, linkage and care retention.
