Bisexual behaviors may increase transmission pathways of HIV and sexually transmitted infections (STIs) from a higher prevalence group to lower prevalence groups in El Salvador. In 2008, men who have sex with men (MSM) were recruited in San Salvador and San Miguel using respondent driven sampling. Participants were interviewed and tested for HIV and STIs. Sixteen seeds and 797 MSM participated; 34.9% in San Salvador and 58.8% in San Miguel reported bisexual behavior. Bisexual behavior was associated with drug use (adjusted odds ratio (AOR) = 2.57, 95% CI: 1.30-5.06) and insertive anal sex (AOR = 5.45, 95% CI: 3.01-9.87), and inversely associated with having a stable male partner (AOR = 0.47, 95% CI: 0.26-0.84) and disclosing MSM behavior to family (AOR = 0.41, 95% CI: 0.22-0.75). Bisexual behavior was associated with risk behaviors with male and female partners that may be associated with HIV and STI transmission. Bisexual men displayed a distinct identity calling for tailored interventions.
双性恋行为可能会增加艾滋病毒和性传播感染（STI）在萨尔瓦多从高流行群体向低流行群体传播的途径。2008 年，采用应答驱动抽样法在圣萨尔瓦多和圣米格尔招募了与男性发生性关系的男性（MSM）。参与者接受了艾滋病毒和性传播感染的检测和访谈。共招募了 16 名种子参与者和 797 名 MSM，其中 34.9%的参与者来自圣萨尔瓦多，58.8%的参与者来自圣米格尔，报告存在双性恋行为。双性恋行为与吸毒（调整后的优势比（AOR）=2.57，95%置信区间：1.30-5.06）和插入性肛交（AOR=5.45，95%置信区间：3.01-9.87）有关，与拥有稳定的男性伴侣（AOR=0.47，95%置信区间：0.26-0.84）和向家人透露 MSM 行为（AOR=0.41，95%置信区间：0.22-0.75）呈负相关。双性恋行为与与男性和女性伴侣发生的风险行为有关，这些行为可能与艾滋病毒和性传播感染的传播有关。双性恋男性表现出一种独特的身份认同，需要有针对性的干预措施。
