Impaired executive function, drug and sex risk, and HIV infection in African American men
METHODS: Using baseline data of the Neuro-HIV Intervention Study (N=244), we estimated adjusted prevalence ratios (APRs) and 95% confidence intervals (CIs) for associations between impaired planning ability (TOL standardized total excess moves score < 10th percentile) and outcomes including risky injection practices (ever having shared needles, cookers, cotton, or rinse water and ever backloaded), casual sex (sex with a partner for less than three months), buying sex, and biologically-confirmed HIV infection.
RESULTS: Approximately 18% were HIV-infected. In analyses adjusting for age and education, impairment on TOL was associated with HIV infection (APR: 1.81, 95% CI: 1.09, 3.01) and with some but not all potential mediating factors including needle sharing (APR: 1.69, 95% CI: 1.03, 2.73) and buying sex (APR: 2.50, 95% CI: 1.66, 3.78). When adjusting for needle sharing and buying sex, factors that may mediate the association between impaired planning and HIV infection, the APR for the association between TOL and HIV strengthened to 1.91 (95% CI: 1.10, 3.33), suggesting other factors likely mediate the relationship.
CONCLUSIONS: Interventions that seek to improve planning may reduce HIV infection among African American men. Additional research is needed to identify the behavioral determinants of HIV infection that are most strongly influenced by impaired executive function.

Qualified on the content I am responsible for because: I am a doctoral student in epidemiology and my research focuses on STI/HIV and related risk behaviors. I have been working with this data for over a year and have presented findings related to executive function and infectious disease in the sample previously.
