大多数关于异性性行为风险的研究都集中在无安全套的阴道性交上，尽管有证据表明无安全套的肛交有明显更高的艾滋病毒传播风险。本研究的重点是男性客户的肛交行为与女性性工作者（FSW）在蒂华纳，墨西哥，那里的艾滋病毒流行病正在增长的高危人群。Logistic回归分析被用来确定男性客户之间的肛交心理和行为的相关性。我们的HIV阴性男性样本（N= 400）主要是拉丁美洲人（87.5%），出生在墨西哥（78.8%），从未结婚（36.8%）或正常或习惯法婚姻（31.5%），就业（62.8%），平均年龄和教育分别为37.8和9.2年。89%的人认为自己是异性恋，11%的人认为自己是双性恋。根据设计，50%的样本居住在蒂华纳，其他50%居住在圣地亚哥县。近一半（49%）的人报告说，在过去的4个月里，至少有一次与蒂华纳的FSW发生肛交;在这些参与者中，85%的人报告说，他们与FSW发生的一次或多次肛交行为没有使用避孕套。在一个多变量模型中，在过去4个月与FSW肛交与双性恋识别，与FSW使用甲基苯丙胺，重复访问相同的FSW，更高的分数对作为FSW的客户端感知的耻辱，和性强迫。预防计划需要解决异性肛交的行为和心理社会相关性，以减少男性客户，FSW及其性网络成员之间的艾滋病毒/性病传播风险。
Most studies of heterosexual sex risk practices have focused on condomless vaginal sex despite evidence that condomless anal sex has a significantly higher risk of HIV transmission. The present study focused on male clients’ anal sex practices with female sex workers (FSWs) in Tijuana, Mexico, where an HIV epidemic is growing among high-risk groups. Logistic regression analyses were used to identify psychosocial and behavioral correlates of anal sex among male clients. Our sample of HIV-negative men (N= 400) was predominantly Latino (87.5 %), born in Mexico (78.8 %), never married (36.8 %) or in a regular or common-law marriage (31.5 %), and employed (62.8 %), with an average age and education of 37.8 and 9.2 years, respectively. Eighty-nine percent identified as heterosexual and 11 % as bisexual. By design, 50 % of the sample resided in Tijuana and the other 50 % in San Diego County. Nearly half (49 %) reported at least one incident of anal sex with a FSW in Tijuana in the past 4 months; of those participants, 85 % reported that one or more of their anal sex acts with FSWs had been without a condom. In a multivariate model, anal sex with a FSW in the past 4 months was associated with bisexual identification, methamphetamine use with FSWs, repeat visits to the same FSW, higher scores on perceived stigma about being a client of FSWs, and sexual compulsivity. Prevention programs are needed that address the behavioral and psychosocial correlates of heterosexual anal sex in order to reduce HIV/STI transmission risk among male clients, FSWs, and their sexual network members.
