ADVERSE PERINATAL EVENTS AND SUBSEQUENT INJURY-RELATED DEATH

一些已发表的研究表明， 在围产期窒息的风险增加， 青少年自杀 然而，这些研究回顾性地使用了 确定的数据和无法控制的不利社会 通常伴随围产期困难的情况。 在这个项目的第一阶段，大约55 000名 1959-66年出生的儿童作为合作项目的对象， 围产期计划计算机化。 在第二阶段， 计算机化的姓名和其他适当的识别信息， 提交给国家死亡指数，所有死亡的受试者 被确认了身份 在第三阶段， 将获得受试者并记录死亡原因。 以来 合作项目收集了大量关于受试者 产前，围产期和儿童史，将有可能 前瞻性研究围产期不良事件与 死亡风险以及死因。

Several published studies have indicated that children experiencing asphyxia during the perinatal period are at increased risk of subsequent adolescent suicide. However, these studies used retrospectively ascertained data and were unable to control for the adverse social conditions that often accompany perinatal difficulties. In the first phase of this project, the names of the approximately 55,000 children who were born during 1959-66 as subjects in the Collaborative Perinatal Project were computerized. During the second phase, the computerized names and other appropriate identifying information were submitted to the National Death Index, and all subjects who have died were identified. In the third phase, the death certificates of these subjects will be obtained and cause of death recorded. Since the Collaborative Project collected extensive data about the subjects' prenatal, perinatal, and childhood histories, it will be possible to study prospectively the relationship between adverse perinatal events and subsequent risk of death, as well as cause of death.
