INFANT MORTALITY AMONG MEXICAN AMERICANS, 1935-1985

研究的主要目的是比较 墨西哥裔美国人死亡率变化分析 和“盎格鲁”（非西班牙裔白色）婴儿在过去的五十年。 为了实现这一目标，我们将开发一个独特的数据库， 匹配的婴儿死亡和出生记录，将允许更广泛的 墨西哥裔美国人死亡经历调查 婴儿比迄今为止可能的（我们建议使 该数据集可供其他研究人员使用， 项目的完成）。 利用这个数据库，我们将 显示婴儿死亡率趋势的差异， 研究死亡风险之间的关系， 新生儿和新生儿后期的年龄和一些因素，包括 婴儿的出生体重和其他特征， 他们的母亲和父亲，以及怀孕的情况， 分娩 本研究的具体目的是：1） 建立一个链接的出生和婴儿死亡记录档案， 1935年至1985年期间， 列出的导致死亡的条件（多种原因），使用 单一疾病分类，并根据 种族识别; 2）追踪西班牙姓氏的趋势， 非西班牙姓氏的新生儿和 根据1935- 1985年的具体原因数据， 1949- 1985年的具体原因和具体重量数据; 3） 确定与下列情况有关的死亡原因代码的不连续性： 修订《国际疾病分类》; 4） 确定当前有利的出生体重 墨西哥裔美国人之间的分布存在于以前 （5）确定主要问题的程度 西班牙姓氏婴儿存活率提高，亲属 与其他白色婴儿相比， 分布和原因与出生体重特异性死亡率 风险 拟议研究的数据来源是出生和 死亡证明由圣安东尼奥市政府保管 卫生区。 已经获得了死亡记录， 目前正在对多种死因进行编码， 人口特征作为我们正在进行的项目的一部分， 墨西哥裔美国人和墨西哥移民的死亡率。

The major objective of the proposed research is the comparative analysis of the transition in the mortality of Mexican American and "Anglo" (non-Hispanic white) infants over the past fifty years. To accomplish this aim, we will develop a unique data base of matched infant death and birth records that will permit a broader investigation of the mortality experience of Mexican American infants than has heretofore been possible (We propose to make this data set available to other researchers following the completion of the project.) Using this data base, we will demonstrate differences in the trends in infant mortality by examining the relationships between mortality risks during the neonatal and postneonatal ages and a number of factors including birth weight and other characteristics of infants, characteristics of their mothers and fathers, and circumstances of pregnancy and parturition. The research has the following specific aims: 1) To develop a file of linked birth and infant death records for the interval 1935-1985 which are coded systematically for all conditions (multiple causes) listed as leading to death, using a single disease classification, and comparably coded according to ethnic identification; 2) To trace trends in Spanish surname and non-Spanish surname infant mortality risk for both neonatal and postneonatal deaths, based on cause specific data for 1935-85 and both cause-specific and weight-specific data for 1949-85; 3) To identify discontinuities in cause of death codes associated with revisions of the International Classification of Diseases; 4) To determine whether the current favorable birth weight distributions among Mexican Americans existed in previous decades; 5) To determine the extent to which the major improvement in survivorship of Spanish surname infants, relative to other white infants, is associated with birth weight distributions and cause versus birth weight specific mortality risks. The source of the data for the proposed study is the birth and death certificates in the custody of the San Antonio Metropolitan Health District. Death records have already been acquired and are currently being coded for multiple causes of death and demographic characteristics as part of our ongoing project on mortality among Mexican-Americans and Mexican immigrants.
