**4.3.1 HIV prevalence by age**

The prevalence according to age group is represented in Table 3. In the overall sample, prevalence of HIV among young people (less than 25 years old) was significantly lower than among people of over 25 years of age (3.5% vs 9.6%). This difference in prevalence according to age group was also significant in Ljubljana where no HIV positive cases were found among younger MSM, and in Bratislava where 1.7% of younger MSM were HIV positive compared to 7.6% of older ones.
