| 摘要: |
| 目的 采用多重对应分析探讨我国西部男男性行为者（MSM）暴露前预防用药（PrEP）宣传途径与社会人口学特征和获得预防艾滋病服务指标之间的对应关系。方法 通过滚雪球抽样的方法，对重庆、四川、广西三地共1 407名MSM进行横断面调查，获得1 323份有效问卷，采用χ2检验进行简单关联分析筛选变量，再进行多重对应分析探索变量间的对应关系。结果 31.49%（416/1 321）的MSM听说过PrEP，希望通过网络、传统大众传媒、同伴教育、医疗机构咨询及服务获得PrEP相关信息的MSM分别占74.00%（979/1 323）、65.00%（860/1 323）、44.22%（585/1 323）和52.15%（690/1 323）。多重对应分析结果显示所有变量在两个维度上的Cronbach 系数分别为0.661和0.632，特征根分别为2.562和2.400；希望通过网络获得PrEP信息与接受过高等教育、未婚、年龄小于30岁、无小孩、城镇户口的MSM有较强关联，希望通过同伴教育获得与接受过伙伴相关知识传播、接受过艾滋病宣传资料、参加过同志工作组活动、接受过艾滋病免费咨询有较强关联。结论 多重对应分析直观地揭示了PrEP宣传途径与社会人口学特征和获得预防艾滋病服务指标之间的对应关系，为PrEP在我国的宣传提供了理论依据，同时也为PrEP在我国的应用研究提供一种新思路。 |

| Abstract: |
| Objective To explore the correlation of propaganda methods of pre-exposure prophylactic medication with sociodemographic characteristics and obtaining services of HIV prevention in men who have sex with men (MSM) in Western China by applying multiple correspondence analysis. Methods A cross-sectional survey was carried out on 1 407 MSM who were selected from Chongqing, Sichuan, Guangxi province by snowball sampling method. Chi-square tests and multiple correspondence analysis were used for selecting variables and exploring correlation. Results Totally 1 323 qualified participants were recruited and only 31.49%(416/1 321) had ever heard of pre-exposure prophylactic medication. It was found that 74.00%(979/1 323), 65.00%(860/1 323), 44.22%(585/1 323) and 52.15%(690/1 323) of MSM were willing to obtain pre-exposure prophylactic medication knowledge via internet, traditional media, peer education and medical institutions, respectively. In multiple correspondence analysis the Cronbach α values were 0.661 and 0.632 while eigenvalues were 2.562 and 2.400 in two dimensions of all variables. Willing to obtain pre-exposure prophylactic medication knowledge via internet was strongly correlated with higher education, unmarried status, younger than 30 years old, no children and urban residency. Willing to obtain knowledge by peer education was strongly correlated with having ever received information from peers, having received promotional materials, having received free AIDS consultation and participated in activities of MSM. Conclusion Multiple correspondence analysis can directly reveal the correlation among propaganda methods of pre-exposure prophylactic medication, sociodemographic characteristics and services of HIV prevention, which provides a theoretical basis for propaganda and research of pre-exposure prophylactic medication among MSM in China. |
