Research indicates that being incarcerated adversely affects disease progression and overall health status. Because HIV infection is a growing problem among prison populations in the United States, understanding how incarceration affects HIV-related survival patterns is critical. The present study examined determinants of HIV-related survival in a cohort of 2380 Texas Department of Criminal Justice (TDCJ) inmates who were treated for HIV/AIDS, dating from January 1, 1992 and June 31, 1997. Assessment of the study factors indicated that there were no substantial violations of the assumptions of the Cox's proportional hazards (PH) model in the present study population. Furthermore, to address the potential problem of censoring- related bias, mortality information was collected on all inmates who were paroled on the basis of disease status. The present study's findings indicate that the following factors were associated with significant decreases in HIV- related survival in the TDCJ prison population: male gender, older age, self- report of no known HIV transmission risk factors, and presence of cytomegalovirus (CMV), Mycobacterium avium complex (MAC), and Pneumocystis carinii pneumonia. Moreover, survival decreased in a monotonic fashion with decrease in baseline CD4 count. While the majority of the present study's findings were consistent with those reported for nonincarcerated populations, it will be important for investigators to assess whether these findings persist among future cohorts of prison inmates.
