The HIV care continuum is a tool that describes the quality of HIV care for people living with HIV and assesses the extent to which the goal of viral suppression has been achieved. In 2014, we conducted a retrospective cross-sectional study to assess the characteristics associated with three steps of the HIV continuum of care in Italy [i.e., most recent diagnoses, people diagnosed and in care who are on therapy, and people with viral load (VL) suppressed among those on therapy]. Among the 10,262 individuals diagnosed and linked to care, 9,810 (95.6%) were on therapy and among these 8,383 (85.7%) had VL suppressed. The comparison between people diagnosed in 2013 to those diagnosed before 2013 shows that they were more likely to be male [adjusted odds ratios (AOR) = 1.46; 95% confidence interval (95% CI): 1.18-1.79], <25 years of age (AOR = 7.59; 95% CI: 4.17-13.79), and born in Italy (AOR = 1.33; 95% CI: 1.09-1.62). Factors significantly associated with not being in therapy were as follows: age <35 years (AOR = 4.03; 95% CI: 2.50-6.51), age 35-55 years (AOR = 1.85; 95% CI: 1.19-2.87), being migrants (AOR = 1.25; 95% CI: 1.13-1.39), being men who have sex with men (MSM) (AOR = 1.54; 95% CI: 1.22-1.95), have been diagnosed in 2010-2012 (AOR = 4.51; 95% CI: 3.03-6.73), or before 2010 (AOR = 3.18; 95% CI: 2.41-4.21), and not had previous clinical AIDS (AOR = 8.24; 95% CI: 3.33-20.23), whereas factors significantly associated with not having VL suppressed were as follows: age <35 years (AOR = 1.56; 95% CI: 1.13-2.13) and age 35-55 years (AOR = 1.23; 95% CI: 1.10-1.38), being migrants (AOR = 1.38; 95% CI: 1.11-1.70), have been diagnosed in 2010-2012 (AOR = 1.34; 95% CI: 1.14-1.57), in 2013 (AOR = 4.35; 95% CI: 2.47-7.68), and not having had previous clinical AIDS (AOR = 0.74; 95% CI: 0.63-0.86). Despite this we observed significant disparities for young people, MSM, and migrants, overall in Italy the vast majority of people diagnosed with HIV and in care in 2013 received therapy and the percentage of people who are VL suppressed is near the Joint United Nations Programme on HIV/AIDS goal.
