Binary logistic regression was used to compare men tested as part of a regular sexual health check and those tested in response to a perceived risk event (Table 4). The odds of having had an HIV test because of a perceived risk event remained significantly higher among the London survey sample compared with Glasgow/Edinburgh, and among men reporting higher risk sexual behaviour than among men not reporting this behaviour. The adjusted odds were significantly lower among men aged ≥ 46 years and men aged 26–35 years, than among those aged ≤ 25 years, and among those reporting more frequent HIV testing in the previous 2 years. All variables remained significant in the multivariate model.
