Access to treatment among European MSM with diagnosed HIV
We have just published in PLoS One the reasons for not taking anti-retroviral treatment (ART) from EMIS, our large Pan-European Internet survey which included 13,353 MSM with diagnosed HIV living in more than 30 countries. A quarter (25.4%) had never received ART, but a small proportion (2.1%) had started and since stopped taking ART. Perceived lack of need was by far the most common reason for not taking or stopping ART (mentioned by 88.8%), followed by fear of consequences (11.7%), and ART inaccessibility (2.3%). For all reasons, an East-West gradient could be seen, with larger proportions of men living in Central and Eastern Europe reporting reasons other than medical advice for not taking ART. A minority were reluctant to start ART independent of medical advice and this was associated with experiences of discrimination in health care. ART is widely available for MSM diagnosed with HIV across Europe and not being on treatment is predominantly due to treatment not being recommended by their physician and/or not perceived to be needed by the respondent.
