Use of antiretroviral therapy among HIV positive individuals living in British Columbia.
The objective of this study was to examine the level of antiretroviral use and characterize individuals accessing antiretroviral therapy in British Columbia. The study was conducted by the British Columbia Persons with AIDS Society and the British Columbia Centre for Excellence in HIV/AIDS. Self-administered questionnaires were mailed out to HIV-positive members from May to September of 2002. Comparisons of sociodemographic characteristics and disease status were made using Pearson's Chi2 and the Kruskal-Wallis test for continuous variables. A total of 764 (51%) HIV-positive participants returned the questionnaire. Of these, 80% reported ever using antiretroviral therapy and 64.5% indicated current use. Reasons for never taking antiretroviral therapy were high CD4 or doctor's advice (74/126; 59%), feeling healthy (50/126; 40%) and being afraid of side-effects (35/126; 28%). Those reporting current antiretroviral use were more likely to be older (p<0.001), white (p=0.01), male (p<0.001), gay or bisexual (p<0.001), graduated from high school (p=0.001), non-injecting drug user (IDU) (p<0.001) and earning a household income greater than CAN$10,000/year (p=0.003). IDU status and length of time since diagnosis remained significantly associated with antiretroviral use in multivariate models. The differences in current antiretroviral use by sociodemographic characteristics such as IDU suggest that the need remains to target marginalized populations in order to maximize the health benefits from antiretroviral therapy.
