台灣年輕男性間性行為者之手機交友軟體使用 與危險性行為之關聯：探討性刺激尋求傾向之調節作用

Abstract

背景：具地理定位功能之手機交友軟體，已逐漸成為台灣年輕男性間性行為者間受歡迎之社群平台。過去研究發現使用交友軟體者，在性行為的表現，相較於沒有使用交友軟體者是更加活躍的。此外，亦有研究證實具性刺激尋求傾向之男性間性行為者，與發生危險性行為是具正向關係。刺激尋求傾向也曾被當作會發生危險性行為之調節因子。然針對手機交友軟體使用與危險性行為之關聯卻很少被研究。 目的：本研究欲了解台灣年輕男性間性行為者其手機交友軟體使用特質，並探討此交友軟體使用型態，與其是否和交友軟體認識之朋友發生危險性行為具關聯性。同時，本研究亦檢視性刺激尋求傾向，是否扮演著手機交友軟體使用與危險性行為之調節因子。 方法：本研究針對全台灣15至39歲年輕男同志，透過網路匿名問卷進行資料蒐集，最後有效分析樣本數為688人，統計方法以多變項回歸模型進行分析。 結果：台灣年輕男同志使用手機交友軟體者，以使用Jack’d者為最多，共佔59%。其中，54.9%之男同志回答其過去一年內，曾與手機交友軟體之對象發生肛交行為。本研究發現相較於使用非Jack’d者，使用Jack’d之男同志 (AOR=0.5)，其與交友軟體上之對象發生肛交行為的機率顯著降低2倍。低性刺激尋求者，具有以下特質較易與交友軟體之對象發生肛交：目前獨居者 (AOR=2.73)、與其他友人同居者 (AOR=2.70)，性角色為不分偏0號者 (AOR=2.75)、與交友軟體之對象約在對方住處者 (AOR=7.14)，約在自己住處者 (AOR=5.48)、約在旅館者 (AOR=4.57)，對交友軟體之性器官資訊感興趣者 (AOR=5.15)。高性刺激尋求者，具有以下特質較易與交友軟體之對象發生肛交：服役者 (AOR=7.91)；性角色為不分偏1號者(AOR=2.55)；與交友軟體上之對象約在旅館者 (AOR=2.70)；一個人無聊時(AOR=3.28)使用交友軟體找尋性伴侶者、連續假日時 (AOR=3.04)使用交友軟體找尋性伴侶者；對交友軟體上之性器官資訊感興趣者 (AOR=5.15)。 結論：本研究發現發生肛交行為之相關因素會因性刺激尋求傾向高低而不同，即其為一調節因子。居住情況、性角色、交友軟體之圖片與資訊、與交友軟體之對象相約性行為的地點和當下使用交友軟體找尋性伴侶之情境，都和是否與交友軟體之對象發生肛交行為有顯著關係。建議未來研究能深入探究性刺激尋求傾向之調節作用的機轉，並了解低、高性刺激尋求傾向者在使用手機交友軟體與發生危險性行為表露之不同意涵。

Background: Geosocial networking application (“app”) use has become increasingly popular among young men who have sex with men (YMSM) in Taiwan, and has been found to be associated with more sexual activities. Sexual sensation seeking (SSS) tendency is also positively related to more sexual risk-taking. Prior research has identified sensation seeking as a moderator of sexual risk behavior among YMSM. However, little is known about the effects of their app use on sexual risk-taking. Objectives: This study aimed to examine the characteristics of app use, and to explore the associated factors of anal sex with apps-met partners (AMPs), among YMSM in Taiwan. The moderating effects of SSS tendency were also explored. Methods: Data were collected from 688 apps-using YMSM aged 15–39 years through an anonymous online survey. Multivariate logistic regression was used for data analysis. Results: The majority of apps-using YMSM in Taiwan used Jack’d (59.0%). About 54.9% of YMSM reported having anal sex with AMPs in the past 12 months. Besides, YMSM who reported Jack’d as their most frequently used app were significantly less likely to have anal sex with AMPs (AOR=0.50) than their non-Jack’d counterparts. Among low-SSS YMSM, those living alone (AOR=2.73) and with others (AOR=2.70), rather than with family, and those in a sexually receptive role (AOR=2.75) were more likely to have anal sex with AMPs. YMSM who usually had sex with AMPs in their AMP’s place (AOR=7.14), their own place (AOR=5.48), and a hotel (AOR=4.57), and YMSM interested in information shown on apps about penis (AOR=5.15), were significantly more likely to have anal sex with AMPs. However, YMSM in a relationship with only one partner (AOR=0.25), and those interested in photos of abdomen (AOR=0.29) and information shown on apps about height (AOR=0.30) and relationship status (AOR=0.44), were less likely to have anal sex with AMPs. Among high-SSS YMSM, those in the military (AOR=7.91), living alone (AOR=3.84), and assuming a sexually insertive role (AOR=2.55) were more likely to have anal sex with AMPs. YMSM who usually had sex with AMPs in a hotel (AOR=2.70), who tended to seek sex via apps when bored and alone (AOR=3.28) and on holidays (AOR=3.04), and who were interested in information shown on apps about penis (AOR=2.53), were more likely to have anal sex with AMPs. High-SSS YMSM interested in photos of hair (AOR=0.41) were less likely to have anal sex with AMPs. Conclusions: This study found that the factors associated with sexual risk-taking behavior differed between low-SSS and high-SSS YMSM, indicating significant moderating effects. Notably, living status, places for hook-up sex, sex role, photos and information shown on apps, and contexts of sex-seeking via apps had significant effects on anal sex with AMPs among YMSM. More research is needed to further explore the mechanisms of such moderating effects and the different implications of app use in their sexual risk-taking in low-SSS and high-SSS YMSM.
