背景国内人口流动在中国的艾滋病流行中起着重要作用。然而，很少有研究直接比较了与男性发生性关系的移民男性（MSM）与当地MSM的艾滋病毒/性传播感染（STI）风险。方法.我们在中国广州进行了一项研究，目的是了解流动MSM和本地MSM之间艾滋病毒/性传播疾病风险的差异。对广州市273名流动男男性行为者和249名本地男男性行为者进行了横断面调查。收集两组患者的行为学和HIV/梅毒血清学资料，并进行比较。多变量logistic回归被用来估计艾滋病毒/性传播感染的风险和移民身份之间的关联。结果与本地MSM相比，移民MSM报告无保护肛交（UAI）（OR = 1.4; 95%CI [0.9-2.0]）和有多个同性恋伴侣（OR = 1.2; 95%CI [0.8-1.8]）的几率更高。流动人群首次性行为时安全套使用率低于本地人群（OR = 0.7; 95%CI [0.5-0.9]）。相对于本地MSM，移民MSM在过去6个月内报告HIV/STI检测的几率较小（OR = 0.5; 95%CI [0.4-0.8]）。此外，流动MSM表现出较低的艾滋病毒知识水平比本地MSM（OR = 0.4; 95%CI [0.2-0.8]）。结论流动男男性接触者更有可能从事危险性行为，报告艾滋病毒知识水平较低，获得艾滋病毒/性传播感染检测的机会较少。敦促采取针对移徙男男性行为者的进一步综合干预措施。
Background. Internal migration plays a significant role in China’s HIV epidemic. However, few studies have directly compared migrant men who have sex with men (MSM) with local MSM with regard to HIV/sexually transmitted infections (STIs) risks. Methods. We conducted a study in Guangzhou, China, with the aim of understanding the differences in HIV/STIs risks between migrant MSM and local MSM. A cross-sectional study was conducted among 273 migrant MSM and 249 local MSM in Guangzhou, China. Their behavioral and serologic data on HIV/syphilis were collected and compared between the two groups. A multivariate logistic regression was used to estimate the associations between HIV/STIs risks and migratory status. Results. Migrant MSM, compared to local MSM, have higher odds of reporting unprotected anal intercourse (UAI) (OR = 1.4; 95% CI [0.9–2.0]) and having multiple homosexual partners (OR = 1.2; 95% CI [0.8–1.8]). A lower rate of condom use at homosexual debut was reported in migrant MSM than in local MSM (OR = 0.7; 95% CI [0.5–0.9]). Migrant MSM have less odds of reporting HIV/STIs testing in the previous 6 months relative to local MSM (OR = 0.5; 95% CI [0.4–0.8]). In addition, migrant MSM demonstrated a lower level of HIV knowledge than local MSM (OR = 0.4; 95% CI [0.2–0.8]). Conclusion. Migrant MSM are more likely to engage in sexual risk behaviors, report a lower level of HIV knowledge and have less access to HIV/STIs testing. Further comprehensive interventions targeting migrant MSM are urged.
