INFANT MORTALITY AMONG MEXICAN AMERICANS, 1935-1985

拟议研究的主要目标是比较 墨西哥裔美国人死亡率的变迁分析 和“盎格鲁”(非西班牙裔白人)婴儿在过去的50年里。 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 比到目前为止可能的婴儿数量更多(我们建议 这一数据集可供其他研究人员使用 项目竣工。)使用这个数据库，我们将 展示婴儿死亡率趋势的差异 检查死亡风险之间的关系 新生儿和新生儿后年龄以及一些因素，包括 出生体重和婴儿的其他特征，特征 他们的父母，怀孕的情况和 分娩。本研究有以下具体目的：1) 建立一份将出生和婴儿死亡记录联系起来的文件 1935-1985年期间，对所有人进行了系统编码 列出的导致死亡的情况(多个原因)，使用 单种疾病分类，并根据 种族认同；2)追踪西班牙姓氏和 非西班牙姓氏新生儿和婴儿死亡风险 新生儿死亡，基于1935-85年和1935-85年的特定原因数据 1949-85年特定原因和特定体重的数据；3)至 识别与以下相关的死因代码中的不连续项 修订《国际疾病分类》；4)改为 确定当前有利的出生体重 在墨西哥裔美国人中的分配在以前 几十年；5)确定主要的 西班牙姓氏婴儿存活率的提高 对其他白人婴儿来说，与出生体重有关 分布和原因与出生体重特定死亡率的关系 风险。 这项拟议研究的数据来源是出生和 由圣安东尼奥大都会保管的死亡证明 卫生区。死亡记录已经被获取， 目前正在对多种死因进行编码， 人口统计特征是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.
