Migration Effects on Health of Working Age Vietnamese

这项拟议的研究将检查生活在美国和越南的越南人的一些健康后果。一个主要的实质性重点将是调查最近移民到美国的处于工作年龄的越南成年人的总体健康状况和核心健康信念。将暴露的健康的关键方面包括身体功能、角色限制、疼痛、社会功能、一般心理健康、压力、活力、精力、疲劳和一般健康认知。虽然有大量关于其他主要移民群体健康状况的文献，但我们对越南裔美国人的健康状况知之甚少，他们构成了近代史上规模最大的移民潮之一。一个主要的方法重点将涉及开发新的技术，以更好地解释移民和非移民之间的健康差异。将已报告的移徙对健康的影响归因于特定的原因，这是因为将移徙本身的影响与选择因素分开的固有困难。如果移民不能代表派遣人口，那么就很难解释派遣国移民和非移民之间的差异。我们将移民效应与选择效应分开的方法涉及一个“自然”实验，该实验比较了三个不同的群体：在美国的越南移民；从未离开过越南的越南人；以及在越南的越南回归者。

The proposed study will examine a number of health outcomes among Vietnamese living both in the United States and in Vietnam. A major substantive focus will be the investigation of overall health status and core health beliefs among working-age Vietnamese adults who have recently immigrated to the United States. Key dimensions of health to be exposed include physical functioning, role limitations, pain, social functioning, general mental health, stress, vitality, energy, fatigue, and general health perceptions. While there is an extensive literature on the health of other major immigrant groups, we know much less about the health of Vietnamese Americans, who constitute one of the largest waves of immigration to the United States in recent history. A major methodological focus will involve the development of new techniques to better explain health differences between migrants and non-migrants. Attributing reported effects of migration on health to specific causes are complicated by the inherent difficulties of separating the effects of migration per se from selection factors. If migrants are not representative of sending populations, then differences between migrants and non-migrants in the sending countries are difficult to interpret. Our approach to separating migration effects from selection effects involves a "natural" experiment that compares three distinct groups: Vietnamese immigrants in the United States; Vietnamese who have never left Vietnam; and Vietnamese returnees in Vietnam.
