项目摘要

The majority of HIV transmission takes place between individuals via sexual contacts. At a population level, these partnerships can be viewed as connected into a dynamic sexual partnership network, whose structural and compositional characteristics influence, and are influenced by, the HIV epidemic. Although this is well understood, lack of data and a framework for utilising sampled network data and strategies for translating simulation findings into health promotion strategies has prevented the use of data-driven dynamic network mathematical models to inform the design of interventions in specific settings. The way that individuals seek and form sexual partnerships is changing in many settings, and so plausibly are the characteristics of the sexual partnership network. A rapid rise in the use of online social media is occurring not only in high income settings, but also in sub-Saharan Africa. It is now both critical and feasible to develop a framework for data-driven dynamic partnership network models of HIV transmission, to understand the intersection of HIV acquisition and transmission risk with online socialising and partner-seeking, and to ensure that HIV prevention and engagement in care interventions can be most effectively designed and targeted.A key group affected by HIV across the world is men who have sex with men (MSM), including in sub-Saharan Africa (SSA). Studies of MSM in SSA have found high HIV prevalence and incidence, alongside widespread experience of social stigma, violence, harassment and poor access to sexual health services. The incentives for MSM to socialise and seek partners online are high, and correspondingly, there is great potential to use online social media venues to provide information or referrals for in-person HIV prevention, testing and care services. This project will use unique and current data on sexual partnerships, online and offline-initiated, HIV status and engagement in care, and social media use from representative samples of MSM from Nairobi and Johannesburg to develop dynamic network models of HIV transmission, explore the potential role of social media use in HIV transmission, and bring networks-based insight to improve targeting of health promotion and inform intervention development and future research to reduce HIV incidence.

大多数艾滋病毒传播是通过性接触在人与人之间发生的。在人口层面，这些伙伴关系可以被视为连接到一个动态的性伙伴关系网络，其结构和组成特征影响着艾滋病毒的流行，也受到艾滋病毒流行的影响。尽管这一点众所周知，但缺乏利用采样网络数据的数据和框架以及将模拟结果转化为健康促进策略的策略，阻碍了使用数据驱动的动态网络数学模型来为特定环境下的干预措施设计提供信息。在许多环境中，个人寻求和建立性伙伴关系的方式正在发生变化，性伙伴关系网络的特征也因此发生了变化。在线社交媒体的使用迅速增加不仅发生在高收入环境中，而且发生在撒哈拉以南非洲地区。现在，开发一个数据驱动的动态艾滋病毒传播伙伴关系网络模型框架，了解艾滋病毒感染和传播风险与在线社交和寻求伴侣的交叉点，并确保艾滋病毒预防和参与，既关键又可行。可以最有效地设计和瞄准护理干预措施。全世界受艾滋病毒影响的一个关键群体是男男性行为者 (MSM)，包括撒哈拉以南非洲地区 (SSA)。对撒哈拉以南非洲地区男男性行为者的研究发现，艾滋病毒流行率和发病率很高，同时普遍存在社会耻辱、暴力、骚扰和难以获得性健康服务。 MSM 在网上社交和寻找伴侣的动机很高，相应地，利用在线社交媒体场所提供面对面艾滋病毒预防、检测和护理服务的信息或转介的潜力很大。该项目将使用来自内罗毕和约翰内斯堡的 MSM 代表性样本的有关性伙伴关系、线上和线下发起的、艾滋病毒状况和护理参与度以及社交媒体使用情况的独特且最新的数据，以开发艾滋病毒传播的动态网络模型，探索艾滋病毒传播的潜力。社交媒体的使用在艾滋病毒传播中的作用，并带来基于网络的洞察力，以提高健康促进的针对性，并为干预措施的制定和未来的研究提供信息，以减少艾滋病毒的发病率。
