Preference towards HIV Self-Testing above Other Testing Options in a Sample of Men Who Have Sex with Men from Five European Countries.

We analyzed men who have sex with men (MSM) from Denmark, Germany, Greece, Portugal and Spain to identify who would choose HIV self-testing as their preferred testing method and assessed their preferred setting to acquire a self-testing kit and to confirm a reactive result. In 2016, we recruited an online sample of 3725 HIV-negative MSM. We used Poisson regression to identify factors associated with choosing self-testing as the preferred testing option. For those choosing it as their preferred option, we assessed the preferred settings to acquire a self-testing kit and to confirm a reactive result. Not being open about one's sexual behaviors with men was associated with choosing self-testing as the preferred option, except in Greece; older age in Greece and Spain; reporting condomless anal intercourses (CAI) in Germany and Portugal; reporting one previous test in Greece; between 2 and 5 in Spain and with having been tested ≥ 12 months ago in Germany, Portugal and Spain. The internet (32.8%) was the preferred place to acquire a self-testing kit and primary care (34.0%) for confirmation purposes. Self-testing was highly valued, especially among individuals who were not open about their sexual behaviors with men. In certain countries, it was also associated with older age, CAI and being undertested.This study was supported by Consumers, Health and Food Executive Agency (CHAFEA: 20131101) and Acción Estratégica Intramural (PI17CIII/00037).
