The present study reports the results of 2 surveys examining the likelihood of performing HIV antibody test among the Hong Kong mainland China traveller population. The 2 studies interviewed 1325 and 2074 male adult Hong Kong residents. Among those who had had sexual intercourse with a female sex worker (FSW) in the past 6 months, 31.1% in the first sample indicated that they intended to take an HIV antibody test in the future, whereas 16.4% in the second sample reported they had actually taken a blood test for HIV antibody. In both samples, no association was found between demographic variables, attitudinal/knowledge-related variables and intention to do a blood test for HIV antibody and actual testing behaviour. Moreover, in both samples, those who had more female sexual partners in the past 6 months were more likely to report an intention for HIV test or to have taken an HIV test.
