本研究的目的在探討嫖客對愛滋病防治的知識、態度與行為之現況與其預防行為之相關因素。本研究為橫斷式研究，採用自擬的結構式問卷，於台北市之公娼與私娼地區，以立意取樣法收集203位樣本之相關資料。經統計分析後，研究結果顯示:嫖客在知識部分答對率為69.5%，其中以「愛滋病是傳染性疾病」與「愛滋病的檢查方法」的認識得分最高，「易感染群」與「政府指定愛滋病篩檢場所」的認識得分最低。在態度方面，整體的態度傾向沒有意見。在預防愛滋病的行為方面，嫖客在性交易時每次都會接受性工作者要求使用保險套佔7l.6%，嫖客所遇到的性工作者未要求戴上保險套時，每一次都會主動使用保險套佔51.2%，另嫖客與其他性伴侶保險套的使用佔12.3%，從未檢查過愛滋病者佔67.7%。嫖客保險套使用情形與嫖客的年齡、婚姻、教育程度、職業、平均每月收入、罹患性病的情形與飲酒、藥物濫用及態度有顯著的相關，然愛滋病的預防行為則與知識無關。

The purpose of this study was to investigate brothel clients' knowledge of, and attitude and behavior toward AIDS, and to identify the related factors affecting preventive behavior. This study used a cross-sectional design. Data were callected through a structured questionnaire answered by 203 participants who fre-quented legal and illegal brothels in Taipei. Obtained by means of statistical analysis, the major findings of this study were: about the clients knowledge of AIDS, the rate of correct answers was 69.5%. Knowledge about AIDS as a transmitted disease and about AIDS screening methods scored the highest; knowledge about the most vulnerable population and government-appointed screening centers scored the lowest. Attitude towards AIDS tends to be neutral overall. As to preventive behavior, 7l.6% of the participants routinely accepted a prostitute's request to use a condom and 51.2% of participants routinely used condoms on their own initiative. But the study found that only 12.3% of participants routinely used condom with other sexual partners, and 67.7% had never been tesed for HIV. Participants' use of condoms was significantly related to age, marital status, educational level, occupation, average income, past history of having sexually transmitted diseases, alcohol consumption, drug abuse and the attitude toward AIDS. However, the participants' preventive beha-vior was not found to be significantly related to knowledge of AIDS.
