A better understanding of HIV transmission dynamics is needed to further reduce the number of new HIV diagnoses in Belgium. As environmental and social context play an important role in explaining HIV acquisition despite the availability of effective HIV prevention, this study investigated how social and sexual networks may have influenced HIV prevention and risk behavior among a group of people newly diagnosed with HIV, including their perceptions of how they acquired HIV and their ability to disclose their HIV status.
We used an ego-centric social network approach, generating sociograms of social and sexual networks through in-depth interviews with 20 participants newly diagnosed with HIV.
Many participants reported a considerable overlap between their social and sexual networks. Friends, family members, regular sex partners and HIV physicians were placed closest to the ego on the sociogram. Self-identified gay men did not consider their casual sex partners as emotionally close enough to be included in the sociogram, despite these partners often being participants' primary source of information about sexual health. Self-identified heterosexual and bisexual men who have sex with men (MSM) had more diverse and separated networks, and often had not considered themselves at risk for HIV. They were less aware of PrEP compared to self-identified gay MSM, partly attributed to target-group specific community-based prevention efforts. Most participants disclosed HIV only to those closest to them, and the anticipated and perceived lack of social support influenced acceptance. Feelings of internalized HIV stigma and homophobia prevented HIV disclosure, especially among heterosexuals and heterosexual and bisexual MSM.
This study revealed important differences in the networks of gay-identified MSM, heterosexuals and hetero- and bisexual identified MSM influencing sexual risk taking and prevention behavior. Future prevention initiatives should be inclusive and mainstreamed to ensure to address those who do not identify as belonging established key populations. Awareness of HIV and biomedical prevention should be raised in the general population, providing a base on which tailored prevention can be built. Involving family physicians and socially empowering people living with HIV may help to decrease anticipated and internalized HIV stigma.
为进一步减少比利时新确诊的艾滋病毒感染病例数量,需要更好地了解艾滋病毒传播动态。尽管有有效的艾滋病毒预防措施,但环境和社会背景在解释艾滋病毒感染方面起着重要作用,本研究调查了社会和性网络如何影响一组新确诊艾滋病毒感染者的艾滋病毒预防和风险行为,包括他们对感染艾滋病毒途径的认知以及披露其艾滋病毒感染状况的能力。
我们采用以自我为中心的社会网络方法,通过对20名新确诊艾滋病毒感染者进行深入访谈,绘制社会和性网络的社会关系图。
许多参与者报告称其社会网络和性网络有相当大的重叠。在社会关系图上,朋友、家庭成员、固定性伴侣和艾滋病毒医生离自我中心最近。自我认定的男同性恋者不认为他们的临时性伴侣在情感上与自己亲近到足以被纳入社会关系图,尽管这些伴侣往往是参与者性健康信息的主要来源。自我认定的异性恋者和与男性发生性关系的双性恋男性(MSM)的网络更多样化且相互分离,他们通常不认为自己有感染艾滋病毒的风险。与自我认定的男同性恋MSM相比,他们对暴露前预防(PrEP)的了解较少,部分原因是针对特定目标群体的社区预防工作。大多数参与者只向最亲近的人披露自己感染艾滋病毒的情况,而预期和感知到的社会支持不足影响了这种接受度。内化的艾滋病毒耻辱感和恐同情绪阻碍了艾滋病毒感染状况的披露,尤其是在异性恋者以及异性恋和双性恋MSM中。
本研究揭示了自我认定的男同性恋MSM、异性恋者以及异性恋和双性恋MSM在网络方面的重要差异,这些差异影响着性风险行为和预防行为。未来的预防举措应具有包容性并纳入主流,以确保针对那些不认为自己属于既定关键人群的人。应提高普通人群对艾滋病毒和生物医学预防的认识,为开展针对性预防奠定基础。让家庭医生参与并增强艾滋病毒感染者的社会权能可能有助于减少预期的和内化的艾滋病毒耻辱感。
