Multivariate logistic regression analyses were conducted to assess characteristics associated with never having

been tested for HIV. Of the 13 111 participants, 26% were untested. By size of population, untested MSM were more likely to live in cities with fewer than 500 000 inhabitants (60% versus 44% for tested MSM; P < 0.05). In general, untested MSM were more likely to be younger than 25 years old (43% versus 16% for tested MSM; P < 0.05), with a median age of 26 years versus 33 years for tested MSM. Using the International Standard Classification of Educational Degrees to categorize education level, most untested MSM had a medium (38% versus 30% for tested MSM; P < 0.05) or low (11% versus 8% for tested MSM; P < 0.05) level of education. Regarding employment, untested MSM were significantly

JQ1 chemical structure more likely to be students selleck compound (32% versus 12% for tested MSM; P < 0.05) compared with tested MSM. More untested MSM identified themselves as bisexual (18% versus 10% for tested MSM; P < 0.05) or had not yet defined their sexual identity (10% versus 7% for tested MSM; P < 0.05). In comparison with tested MSM, fewer untested MSM had visited commercial gay venues (72% versus 90% for tested MSM; P < 0.05) and sex venues (47% versus 68% for tested MSM; P < 0.05) in the last 12 months. The number of nonsteady partners was lower among untested than among tested MSM. Men who reported fewer than three partners or no nonsteady partner in the last 12 months were more likely to be untested (54% versus 32% for tested MSM; P < 0.05). Unprotected anal intercourse (UAI) with a steady partner was more frequent among untested MSM (76% versus 73% for tested MSM; P < 0.05). There was Docetaxel in vivo no significant difference between the untested and tested MSM in relation to UAI with nonsteady partners in the last 12 months (45% versus 47%, respectively; P > 0.05). A higher proportion of untested MSM had UAI

with a steady partner whose HIV status was unknown or discordant (30% versus 7% for tested MSM; P < 0.05). The nonuse of drugs in the last 12 months was more common among untested MSM than among tested MSM (64% versus 43%, respectively; P < 0.05). Almost five times fewer untested MSM than tested MSM had had a diagnosis of an STI (syphilis, gonorrhea, chlamydia, genital warts or herpes) in the last 12 months (3% versus 14%, respectively; P < 0.05). Overall, more untested MSM perceived that they did not have access to free or affordable HIV testing (31% versus 7% for tested MSM; P < 0.05) and felt less confident to access HIV testing than tested MSM (13% versus 3%, respectively; P < 0.05). Multivariate analysis confirmed some factors as being associated with never having been tested among MSM (Table 1): being younger than 25 years old [odds ratio (OR) 2.9; 95% confidence interval (CI) 2.5–3.4], living in settlements with fewer than 500 000 inhabitants (from OR 1.
