使用来自波多黎各母婴健康研究的汇总来源/目的地数据，我们研究了从波多黎各到美国的移民对婴儿死亡率的影响。一项仅限于美国本土的分析显示，移民子女的婴儿死亡率低于本土出生的波多黎各妇女子女的婴儿死亡率。一个关键的问题是，这种模式是否表明母亲接触美国文化会损害婴儿的健康，或者这在很大程度上是更健康或更有优势的母亲选择性移民到美国的结果。我们的研究结果表明，母亲在美国居住的时间与移民子女的婴儿死亡率呈正相关，这表明一个负面同化的过程正在发生。然而，将波多黎各纳入分析表明了选择性移民在解释美国大陆模式方面的重要性：最近移民到大陆的婴儿死亡率大大低于波多黎各非移民妇女的婴儿死亡率。评估了社会经济地位、文化取向、卫生习惯和卫生保健利用在解释母亲移民身份对婴儿生存机会的差异中的作用。
Using pooled origin/destination data from the Puerto Rican Maternal and Infant Health Study, we examine the implications for infant mortality of migration from Puerto Rico to the United States. An analysis restricted to the U.S. mainland shows that children of migrants have lower risks of infant mortality than do children of mainland-born Puerto Rican women. A critical question is whether this pattern indicates that maternal exposure to U.S. culture undermines infant health or whether it is largely a result of the selective migration of healthier or more advantaged mothers to the United States. Our findings show that mother's duration of U.S. residence is positively related to infant mortality among the children of migrants, suggesting that a process of negative assimilation is occurring. However, inclusion of Puerto Rico in the analysis demonstrates the importance of selective migration in explaining the U.S. mainland pattern: Infant mortality is substantially lower among recent migrants to the mainland than it is among nonmigrant women in Puerto Rico. The roles of socioeconomic status, cultural orientation, health habits, and health care utilization in accounting for differences in infants' survival chances by maternal migration status are assessed.
