Disparities in Health among Floating Immigrant Populations

项目摘要 对于拥有12.3亿人口的美国墨西哥移民的健康状况，人们缺乏了解 100万人，受到循环移民模式的影响。这一人群极易受到健康风险的影响， 贫穷、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一问题需要了解在哪些情况下 移民人口在原籍国面临健康风险，而在目的地迁徙 或者在返回本国后，他们才能了解情况。拟议的国际研究合作具有 有潜力为制定干预措施建立坚实的研究基础，以实现卫生公平 美国移民中服务不足的少数族裔群体。提出的研究旨在解决这一知识鸿沟 通过研究移民过程将个人暴露在不同环境中的机制， 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 东道国或原籍社区的疾病和酒精/药物依赖。使用风险共生模型 减少，这项研究提出了一个并发的混合方法嵌套设计来招募600个样本，将 包括(过去5年内)抵达洛杉矶的两个流动新移民小组 以及一群自愿或被迫返回墨西哥城的人。具体目标将：1)确定 身体健康(心血管、代谢失调)、精神健康、感染和 药物滥用/依赖后果；2)确定和描述迁移史之间的关联 和流动人口亚群的健康结果；3)决定个人、社会和 环境决定因素调节和/或调节迁徙亚群和 不同的健康状况结果；4)定性地描述文化和社区背景的影响 关于保持更安全(或风险更高)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.
