We explored the reasons that men who had ever tested provided for having their most recent HIV test (n = 2009). Overall, 1140 (56.7%) tested as part of a regular sexual health check, 714 (35.5%) reported testing in response to a perceived risk event, and 155 (7.7%) tested for other reasons. In comparing the characteristics of the three groups (Table 4), we found that the Glasgow/Edinburgh survey had the highest proportion tested as part of a sexual health check, the London survey had the highest proportion tested after a perceived risk event, and the Scotland‐wide online sample had the highest proportions tested for other reasons (this survey also included the most alternative testing options). Reasons for testing varied with age, with the highest proportion tested after a perceived risk event in the youngest age category (≤ 25 years). Men reporting higher risk UAI in the previous 12 months were more likely to report testing in response to a perceived risk event, although little variation in other sexual risk behaviours was observed. As would be expected, the proportion reporting testing as part of a regular check‐up increased with the frequency of HIV testing.
