摘要

The voluntary anonymous testing for human immunodeficiency virus (HIV) infection plays an important role in the prevention of HIV infection and provides an entry point for HIV care. A cross-sectional questionnaire-based survey was performed among 1008 subjects who voluntarily came to the National Taiwan University Hospital for anonymous HIV testing during May 2006 and July 2007. Over this 15-month study period, 1,008 subjects received 1194 tests. HIV infection was diagnosed in 35 subjects (3.4%) by particle agglutination for anti-HIV antibody followed by confirmation with Western blot. Multiple logistic regression analysis showed that, compared with the non-HIV infected subjects, HIV-infected subjects were older and were more likely to have had sexually-transmitted diseases, had used illicit drugs, had anal sex, and achieved a low level of education (p＜0.05). HIV-infected subjects were more likely to learn the information of the anonymous HIV test via the Internet. Of the 254 subjects who received the first test in the window period, only 81 subjects returned for the second test (31.8%) by July 2007. Those subjects who returned for the second test were more likely to be men, highly educated, heterosexual and single. Comparing the first and second questionnaires completed by the 81 subjects who repeated the test, we found that the rate of condom use with their regular sex partners did not differ significantly (56.7% vs 54.3%). Comparisons of the first and second questionnaires completed by the 152 subjects who repeated the test during the study period showed that the rate of condom use with regular sex partners did not significantly differ as a result of counseling. In conclusion, HIV infection was related to a history of sexually- transmitted diseases, use of illicit drugs, anal sex behavior, and having a HIV-positive spouse or partner among those who sought voluntary HIV testing and counseling. It seems that risk behaviors for the subjects who repeated the test remained unchanged after the one-time counseling. More studies are need to identify effective methods of counseling in order to promote safe sex among the subjects seeking anonymous HIV testing.
