男同性戀者是感染愛滋病的高危險群，在這個群體中，愛滋病傳染如野 火撩原散播開來。本研究主要的目的有三:1.調查高雄地區男同性戀者其性行為現 況2.男同性戀者對於愛滋病威脅的感受3.愛滋病對男同性戀性行為之影響。 本研究採田野研究法，深入男同性戀酒吧，以半結構性問卷、一對一的方式，進 行深度訪談收集資料，並經個案同意後抽血做愛滋病毒抗體(ELISA、WB)的篩 檢。本研究採立意取樣，研究對象為高雄地區某一同性戀酒吧或自願前來高醫愛 滋病防治中心篩檢愛滋病毒(HIV)的男同性戀者。受訪者共計29位(男同性戀22 人，男雙性戀7人)，年齡從18~54歲不等，平均年齡27.4歲(SD=7.27)。本研究的主 要發現如下:1.男同性戀者的性行為以口交、肛交為多，使用保險套的比率偏低。 2.自覺愛滋病威脅主要有三:「生命威脅」、「社交生活受限」、「同性戀身份的 暴露」，即使感受到愛滋病威脅，但是性行為的改變十分有限。3.男同性戀者會 採取「謹慎選擇性伴侶」、「注重個人衛生保健」、「避免去同性戀集會場所」 及「改變性行為方式」來預防愛滋病，僅有少數男同性戀經常使用保險套，男同 性戀者採取預防愛滋病的策略似乎無法有效的防止愛滋病的感染。 從整體的研究結果來看，高雄地區的男同性戀常採取高危險行為，由於怕暴露自 己同性戀的身分，即使感受到愛滋病的威脅，也不敢自動出面做愛滋病毒的篩 檢。由於研究樣本十分難得，因此研究結果的推論十分有限。本研究的建議是須 分辨男同性戀者在其不同的聚會地點及對於不同的性伴侶所採取的性行為方 式，進一步評估其因應愛滋病威脅的方式是否有效。因此唯有進入同性戀群體做 深度訪談的研究結果才有助於相關單位制定有效的愛滋病防治策略。
