Immigrant Selectivity and Disparities in Birth Outcomes

描述（由申请人提供）：拟议的研究将通过探索出生悖论（即外国出生的母亲平均比社会经济地位相似的本地出生的母亲有更好的出生结果），有助于了解健康方面的种族/民族不平等。利用最近三项研究的汇总数据，我们将系统地调查移民选择对出生悖论的影响程度，我们还将通过调查到达美国的年龄和在美国居住的时间对出生结果的影响来测试“文化适应”和“风化”理论。了解移民到美国后健康是如何受到影响的，将为了解美国种族和民族健康差异的决定因素提供一个窗口

DESCRIPTION (provided by applicant): The proposed research will contribute to knowledge about racial/ethnic inequalities in health by exploring the nativity paradox - the fact that foreign born mothers, on average, have better birth outcomes than native born mothers of similar socioeconomic status. Using pooled data from three recent studies, we will systematically investigate the extent to which immigrant selectivity contributes to the nativity paradox and we will also test "acculturation" and "weathering" theories by investigating the effects of age at arrival in the U.S. versus duration of residence in the U.S. on birth outcomes. Understanding how the health of immigrants is affected after immigration to the U.S will provide a window into the determinants of racial and ethnic disparities in health in the U.S. PUBLIC HEALTH RELEVANCE: The proposed research will increase knowledge and information about the causes of disparities in birth outcomes among members of minority groups. This new knowledge should lead to more effective interventions for families and subsequently to better birth outcomes and healthier children.
