Overall, 510 men (21.2%) reported having at least four HIV tests, 812 (33.7%) reported having two or three tests, and 1087 (45.1%) reported having zero or one test in the last 2 years, and we estimate that 54.9% (n = 1322) had at least one test per year. Table 2 compares the characteristics of men reporting fewer than two tests, two or three tests, and at least four tests in the last 2 years. The Scotland‐wide online sample included the highest proportions of men reporting two or three tests and at least four tests in the last 2 years. Significantly higher proportions of older men (aged ≥ 36 years) reported zero or one test in the last 2 years, while reporting at least four tests was most common among younger men (aged ≤ 25 years). There was less age variation in the proportions reporting two or three tests. Men reporting higher risk behaviours (STI, ≥ 10 sexual partners, ≥ 10 AI partners and/or higher risk UAI in the previous 12 months) were consistently more likely to report at least four tests in the last 2 years than men who did not report these behaviours. Other demographic and behavioural variables showed no significant relationship with testing frequency.
