Abstract
We evaluated factors associated with incident self-reported AIDS diagnoses among HIV-infected women in the Women's Interagency HIV Study (WIHS). Baseline information included age, race/ethnicity, HIV risk category, site of enrollment, years of education, cigarette smoking, CD4 cell count, and HIV viral load. Baseline and follow-up data on self-reported AIDS were analyzed using chi-square, Kaplan-Meier, and Cox proportional hazard models. Among the 1397 HIV-infected women who reported being free of clinical AIDS at baseline, 335 women (24%) reported an incident AIDS diagnosis during follow-up. In stratified Kaplan-Meier analyses, the development of self-reported AIDS was significantly associated with baseline CD4 cell count and viral load (p < 0.01). In multivariate Cox proportional hazard analyses, women were statistically more likely to report AIDS if they had CD4 cell counts below 195 cells/mm3 (p < 0.01), HIV RNA > 4000 copies/ml (p < 0.01), were current smokers (p < 0.01), and had "no identifiable risk" for acquisition of HIV (p = 0.03). Self-reports of a clinical AIDS diagnosis may not always be accurate, but laboratory markers of HIV disease indicate that those women who self-report such diagnoses have greater immunodeficiency and a higher viral load when compared with those who report no AIDS-defining diagnoses.
