Abstract

The authors investigated the combined age and HIV effects on cognitive functions in 146 individuals, 116 of whom had HIV infection. Fortytwo percent had HIV-associated neurocognitive disorder, and all were receiving highly active antiretroviral therapy. Using linear and nonlinear regression modeling, the authors found only a trending effect of the quadratic term HIV status age, both including dementia cases (p 0.12) and excluding dementia cases (p 0.06). Our results suggest that either this early-2000 cohort is not old enough to detect a clear interactive age and HIV effect or that there may be a survivor bias for individuals with longterm infection. Further longitudinal studies are warranted
