Use of antiretroviral therapies among HIV-infected men who have sex with men: A household-based sample of 4 major American Cities

Objectives: This study sought to determine the prevalence and determinants of use of recommended antiretroviral regimens among urban seropositive men who have sex with men (MSM). Methods: A probability telephone sample of MSM was taken within regions of Chicago, Los Angetes, New York, and San Francisco. Analysis focused on use of antiretroviral therapies. Results: Although the majority of seropositive MSM with CD4 counts below 500 per microliter were using recommended antiretroviral regimens, 26% of seropositive MSM were not receiving such care. Men who were younger, who reported a sexual orientation other than homosexual, who had a more recent interview date, who were at middle levels of affiliation with the gay community, and who reported higher levels of perceived exclusivity on the part of the gay community were less likely to be using recommended antiretroviral regimens. Conclusions: Although current efforts to make antiretroviral therapies available to HIV-seropositive MSM are reasonably effective, additional efforts are needed for MSM characterized by relative youth and lower social support.
