The present study monitored the trends of HIV/AIDS-related attitudes and perceptions including awareness, knowledge, self-perceived risk of HIV infection, and program evaluation among the general public in Hong Kong over a period of 7 years. Six cross-sectional telephone surveys were conducted. A total of 6,795 respondents aged 18-50 randomly selected from the general population participated in the study. Over the study period, the level of HIV/AIDS-related knowledge has improved slightly for most of the studied items. Condom use has been more widely accepted as an efficacious means of HIV prevention. However, the public seemed to be losing interest in HIV/AIDS-related issues and were not satisfied with the efficacy and adequacy of HIV/AIDS programs in Hong Kong. Sustaining efforts to remove misconceptions and to raise the public's interest, formulation of more effective programs, and ongoing evaluation are necessary.
