Disparities in Health among Floating Immigrant Populations

项目摘要 关于美国墨西哥移民（12.3%的人口）的健康状况如何， 受循环移民模式的影响。这一人群极易受到健康风险的影响， 贫困、歧视、文化差异和移民政策执行带来的压力。 从公共卫生的角度解决这个问题需要了解的条件下， 移民人口在其原籍国面临健康风险，而在其目的地国， 无论是在国内还是回国后。拟议的国际研究合作有 有可能为制定干预措施建立坚实的研究基础，以实现健康公平， 美国移民中的少数民族。这项研究旨在解决这一知识差距 通过研究移民过程使个人暴露于不同环境的机制， 增加对危险行为的易感性，并导致心理和身体健康差异，传染性 疾病和酒精/药物依赖。使用风险共生模型 减少，本研究提出了一个并发的混合方法嵌套设计，招募了600个样本，将 包括两个最近到达洛杉矶的流动移民分组（在过去5年内） 以及一群自愿或被迫返回墨西哥城的人。具体目标是：1）确定 身体健康（心血管、代谢失调）、心理健康、感染和 药物滥用/依赖结果; 2）识别和描述迁移历史之间的关联 流动人口亚组的健康结果; 3）确定个人，社会和 环境决定因素介导和/或调节移徙分组之间的关系， 不同的健康状况结果; 4）定性描述文化和社区背景的影响 关于维持更安全（或更危险）的健康状况和物质使用的战略、做法和情况。

Project Abstract There exists a shortage of knowledge about how the health of US Mexican immigrants, a population of 12.3 million, is impacted by circular immigration patterns. This population is highly vulnerable to health risks and stress arising from poverty, discrimination, cultural differences, and immigration policy enforcement. Addressing this from a public health perspective requires an understanding of the conditions under which immigrant populations are exposed to health risks in their country of origin, while migrating, at their destination context or upon returning to their home country. The proposed international research collaboration has the potential to build a solid research foundation for developing interventions to achieve health equity for an underserved minority population of US immigrants. The research proposed aims to address this knowledge gap by examining the mechanisms by which immigration processes expose individuals to distinct environments, increases susceptibility to risk behaviors and contributes to mental and physical health disparities, infectious diseases and alcohol/drug dependence in the host or origin communities. Using the Symbiotic Model of Risk Reduction, this study proposes a concurrent mixed-methods nested design to recruit a sample of 600 that will include two subgroups of floating recent immigrants (within the past 5 years) that have arrived to Los Angeles and a group who have returned to Mexico City either voluntary or forced. The specific aims will: 1) Determine the prevalence of physical health (cardiovascular, metabolic dysregulation), mental health, infection, and substance abuse/dependence outcomes; 2) Identify and characterize the association between migration histories and health outcomes for the subgroups of floating populations; 3) Determine whether individual, social and environmental determinants mediate and/or moderate the relationships among the migration subgroups and varying health condition outcomes; 4) Characterize qualitatively the influence of culture and community context on strategies, practices and circumstances for maintaining safer (or riskier) health status and substance use.
