A key UK public health priority is to reduce HIV incidence among gay and other men who have sex with men (MSM). This study aimed to explore the social and environmental context in which new HIV infections occurred among MSM in London and Brighton in 2015.
A qualitative descriptive study, comprising in-depth interviews, was carried out as a substudy to the UK Register of HIV Seroconverters cohort: an observational cohort of individuals whose date of HIV seroconversion was well estimated. An inductive thematic analysis was conducted in NVivo, guided by a socio-ecological framework.
Participants were recruited from six HIV clinics in London and Brighton. Fieldwork was conducted between January and April 2015.
All MSM eligible for the UK Register Seroconverter cohort (an HIV-positive antibody test result within 12 months of their last documented HIV-negative test or other laboratory evidence of HIV seroconversion) diagnosed within the past 12 months and aged ≥18 were eligible for the qualitative substudy. 21 MSM participated, aged 22-61 years and predominantly white.
A complex interplay of factors, operating at different levels, influenced risk behaviours and HIV acquisition. Participants saw risk as multi-factorial, but the relative importance of factors varied for each person. Individual psycho-social factors, including personal history, recent life stressors and mental health, enhanced vulnerability towards higher risk situations, while features of the social environment, such as chemsex and social media, and prevalent community beliefs regarding treatment and HIV normalisation, encouraged risk taking.
Recently acquired HIV infection among MSM reflects a complex web of factors operating at different levels. These findings point to the need for multi-level interventions to reduce the risk of HIV acquisition among high-risk MSM in the UK and similar settings.
英国公共卫生的一项关键优先事项是降低男同性恋者及其他男男性行为者(MSM)中的艾滋病毒感染率。本研究旨在探究2015年伦敦和布莱顿的男男性行为者中新发艾滋病毒感染发生的社会和环境背景。
作为英国艾滋病毒血清转化者登记队列研究的子研究,开展了一项定性描述性研究,包括深入访谈。该队列研究是一个观察性队列,对艾滋病毒血清转化日期有良好估计。在NVivo中进行归纳主题分析,以社会生态框架为指导。
参与者从伦敦和布莱顿的六家艾滋病毒诊所招募。实地调查于2015年1月至4月进行。
所有符合英国登记血清转化者队列条件(在其最后一次记录的艾滋病毒阴性检测后12个月内出现艾滋病毒阳性抗体检测结果或其他艾滋病毒血清转化实验室证据)、在过去12个月内确诊且年龄≥18岁的男男性行为者有资格参与定性子研究。21名男男性行为者参与,年龄在22至61岁之间,主要为白人。
在不同层面起作用的多种因素之间存在复杂的相互作用,影响着风险行为和艾滋病毒感染情况。参与者认为风险是多因素的,但各因素的相对重要性因人而异。个人心理社会因素,包括个人经历、近期生活压力源和心理健康状况,增加了处于高风险情况的易感性,而社会环境特征,如化学性行为和社交媒体,以及社区对治疗和艾滋病毒常态化的普遍观念,则鼓励冒险行为。
男男性行为者中近期获得的艾滋病毒感染反映了在不同层面起作用的复杂因素网络。这些发现表明,需要采取多层次干预措施,以降低英国及类似环境中高危男男性行为者感染艾滋病毒的风险。
