Objective: The purpose of this study was to describe the variability in highly active antiretroviral therapy (HAART) regimens over time, the extent to which individuals switch, and the characteristics of those who are switching.
Methods: We evaluated data collected between 1994 and 2000 from 1056 HIV-positive women enrolled in the Women's Interagency HIV Study (WIHS) who reported initiating HAART. We described the variability and prevalence of changes in HAART regimens between semiannual visits, estimated time to switch using Kaplan-Meier methods, investigated factors associated with a first switch using Cox proportional hazards models, and compared disease markers among women switching or remaining on unchanged HAART regimens.
Background: Although HIV-positive women may be less likely than women in general to receive mammography due to socioeconomic disadvantage, HIV diagnosis may increase opportunities for medical interactions which encourage mammography.
Methods: HIV-positive (2,059) and HIV-negative (569) Women's Interagency HIV Study (WIHS) participants reported ever/never history of mammography at baseline (in 1994, 1995) and, at each 6-month follow-up visit, if they had been screened since their last visit. National Health Interview Survey (NHIS) data for 1994 were used to compare WIHS participants to U.
