Abstract
Objectives: Sexual decision-making and sexually transmitted infection (STI) prevention are influenced not only by individuals' characteristics but also by those of their partners and their relationship with each other. To inform STI prevention and understand transmission dynamics, we aimed to understand sexual partnership demographic assortativity, sexual behaviour, communication and concurrency among UK-resident gay, bisexual and other men who have sex with men (GBMSM).
Methods: With community members and organisations, we codesigned a sexual partnerships module for an annual online cross-sectional community-based survey of UK-resident GBMSM (cisgender/trans/non-binary assigned-male-at-birth) undertaken November-December 2023. We collected data about ≤3 most recent male sex partners since August 2023 and analysed variations in relative demographic characteristics (age, ethnicity), sexual behaviours (practices, condom use, HIV-pre-exposure prophylaxis (HIV-PrEP use)) and sexual health communication by partner type (one-time, established, casual and uncertain).
Results: 1106 participants described 2342 partners: 12.5%, 20.4%, 9.9% and 57.1% reporting 0, 1, 2 and 3 partners, respectively, of varying combinations. Casual partner types were most reported (43.2%) versus one-time (36.1%), established (13.9%) and uncertain partnerships (6.8%). Concurrency was common with the mean number of ongoing partnerships >1 (1.23, 95% CI 1.17 to 1.30). Age-mixing varied by partner type, from median 2 (established partners) to 10 (one-time partners) years difference.Sexual health communication was highest among established partners. It was two times as common to be unaware of one-time partners' HIV status (66.8%) and not to have discussed sexual health (65.7%) compared with casual partners (30.0% and 27.2%, respectively). Condom use was low across partner types. HIV-PrEP was always used by HIV-negative participants in two times as many one-time, causal and uncertain partnerships (49.2%, 50.0%, 42.0%) compared with established partnerships (23.3%) involving condomless anal intercourse.
Discussion: UK-resident GBMSM have diverse types of male sexual partners, varying in their demographic mixing, sexual behaviour and communication, which should be reflected in sexual health promotion and transmission dynamics analyses.
目的：性决策和性传播感染（STI）的预防不仅受到个人特征的影响，而且受到其伴侣及其彼此关系的影响。为了预防性传播感染并了解传播动态，我们旨在了解英国同性恋、双性恋和其他男男性行为者（GBMSM）的性伴侣人口分类、性行为、沟通和并发性行为。方法：我们与社区成员和组织共同设计了一个性伙伴关系模块，用于2023年11月至12月进行的英国居民GBMSM（顺性/变性/非二元性别出生时指定的男性）的年度在线横断面社区调查。我们收集了自2023年8月以来≤3名最新男性性伴侣的数据，并分析了相对人口统计学特征（年龄、种族）、性行为（实践、安全套使用、艾滋病毒暴露前预防（HIV-PrEP使用））和按伴侣类型（一次性、已建立、随意和不确定）的性健康交流的变化。结果：1106名参与者描述了2342个伴侣：12.5%、20.4%、9.9%和57.1%分别报告了不同组合的0、1、2和3个伴侣。非正式伴侣类型最多（43.2%），一次性（36.1%），确定（13.9%）和不确定的伴侣类型（6.8%）。并发性在持续伴侣的平均数量bbb1中很常见（1.23,95% CI 1.17至1.30）。年龄混合因伴侣类型而异，中位数相差2岁（已建立伴侣）至10岁（一次性伴侣）。性健康交流在固定伴侣中最高。不知道一次性伴侣的艾滋病毒状况（66.8%）和没有讨论性健康（65.7%）的情况是临时伴侣（分别为30.0%和27.2%）的两倍。不同类型伴侣的安全套使用率都很低。hiv阴性参与者使用HIV-PrEP的一次性、因果关系和不确定伙伴关系（49.2%、50.0%和42.0%）是已建立伙伴关系（23.3%）的两倍，涉及无套肛交。讨论：在英国居住的GBMSM男性性伴侣类型多样，在人口混合、性行为和交流方面各不相同，这应反映在性健康促进和传播动态分析中。
期刊介绍：
Sexually Transmitted Infections is the world’s longest running international journal on sexual health. It aims to keep practitioners, trainees and researchers up to date in the prevention, diagnosis and treatment of all STIs and HIV. The journal publishes original research, descriptive epidemiology, evidence-based reviews and comment on the clinical, public health, sociological and laboratory aspects of sexual health from around the world. We also publish educational articles, letters and other material of interest to readers, along with podcasts and other online material. STI provides a high quality editorial service from submission to publication.
