We examined whether mobility, migrant status, and risk environments are associated with sexually transmitted infections (STIs) and HIV risk behaviors (e.g. sex trading, multiple partners, and unprotected sex).
We used Respondent Driven Sampling (RDS) to recruit external male migrant market vendors from Kyrgyzstan, Uzbekistan, and Tajikistan as well internal migrant and non-migrant market vendors from Kazakhstan. We conducted multivariate logistic regressions to examine the effects of mobility combined with the interaction between mobility and migration status on STIs and sexual risk behaviors, when controlling for risk environment characteristics.
Mobility was associated with increased risk for biologically-confirmed STIs, sex trading, and unprotected sex among non-migrants, but not among internal or external migrants. Condom use rates were low among all three groups, particularly external migrants. Risk environment factors of low-income status, debt, homelessness, and limited access to medical care were associated with unprotected sex among external migrants.
Study findings underscore the role mobility and risk environments play in shaping HIV/STI risks. They highlight the need to consider mobility in the context of migration status and other risk environment factors in developing effective prevention strategies for this population.
我们研究了流动性、移民身份和风险环境是否与性传播感染（STIs）和艾滋病毒风险行为（如性交易、多个性伴侣和无保护性行为）有关。
我们使用受访者驱动抽样（RDS）招募来自吉尔吉斯斯坦、乌兹别克斯坦和塔吉克斯坦的外部男性移民市场摊贩，以及来自哈萨克斯坦的内部移民和非移民市场摊贩。我们进行了多变量逻辑回归分析，以研究流动性与移民身份之间的相互作用对 STIs 和性风险行为的影响，同时控制了风险环境特征。
流动性与非移民中经生物学证实的 STIs、性交易和无保护性行为的风险增加有关，但与内部或外部移民无关。所有三个群体的避孕套使用率都很低，特别是外部移民。低收入、债务、无家可归和有限获得医疗保健等风险环境因素与外部移民的无保护性行为有关。
研究结果强调了流动性和风险环境在塑造艾滋病毒/性传播感染风险方面的作用。它们突出表明，在制定针对这一人群的有效预防策略时，需要考虑到移民身份和其他风险环境因素的流动性。
