We aimed to identify individual and sexual partnership characteristics associated with partner notification (PN) among people with STI. We hypothesised that PN would be less likely in more casual sexual partnerships and in partnerships with intimate partner violence (IPV).
We conducted an observational study among the first 330 patients with STI enrolled in a trial of a behavioural intervention to reduce STI incidence, at a clinic in a poor, Cape Town community. We included 195 index patients (those reporting STI symptoms), and conducted longitudinal analyses using participant-completed questionnaires on the day of diagnosis and 2 weeks later. Using partnership data for five recent sexual partners, we assessed factors associated with reported PN with logistic regressions, adjusting for repeated measurements on the same participant for each partner.
The sample included 99 males with 303 partners and 96 females with 158 partners. Males reported perpetrating IPV in 46.2% of partnerships. Females reported being IPV victims in 53.2% of partnerships. Males notified 58.1%, females 75.4% of partners during the 2 weeks following diagnosis. Type of partner was an independent correlate of PN for males and females, with the odds of PN lower in more casual partnerships. For males, reporting physical IPV perpetration in the partnership was an independent correlate of PN. For females, there was no association between IPV victimisation in a partnership and PN.
Efforts to decrease the pool of infectious partners need to have a strong focus on the promotion of PN in casual relationships and one-night stands. IPV was not identified as a barrier to PN. In future, we need to investigate the association between IPV with an objective measure of PN success such as partner testing or treatment, or index patient reinfection.

我们旨在确定与性传播感染患者的性伴侣通知（PN）相关的个体和性伴侣特征。我们假设，在更随意的性伴侣关系和存在亲密伴侣暴力（IPV）的伴侣关系中，PN 的可能性较小。
我们在开普敦一个贫困社区的诊所中，对参加一项旨在减少性传播感染发生率的行为干预试验的前 330 名性传播感染患者进行了一项观察性研究。我们纳入了 195 名索引患者（报告有性传播感染症状的患者），并在诊断当天和 2 周后使用参与者完成的问卷进行了纵向分析。使用最近 5 个性伴侣的伴侣关系数据，我们使用逻辑回归评估了与报告的 PN 相关的因素，为每个伴侣对同一参与者的重复测量进行了调整。
样本包括 99 名男性和 303 名性伴侣，96 名女性和 158 名性伴侣。男性报告在 46.2%的伴侣关系中实施了 IPV。女性报告在 53.2%的伴侣关系中是 IPV 的受害者。男性在诊断后 2 周内通知了 58.1%的伴侣，女性通知了 75.4%的伴侣。对于男性和女性来说，伴侣类型是 PN 的独立相关因素，在更随意的伴侣关系中，PN 的可能性较低。对于男性来说，报告在伴侣关系中实施身体 IPV 与 PN 有关。对于女性来说，在伴侣关系中遭受 IPV 与 PN 之间没有关联。
减少感染性伴侣数量的努力需要将 PN 在随意关系和一夜情中的推广作为重点。IPV 并不是 PN 的障碍。在未来，我们需要研究 IPV 与 PN 的客观成功指标（如伴侣检测或治疗，或索引患者再感染）之间的关联。
