To evaluate mortality on the first day of life by minute and hour, and examine changes in major causes of death in the past three decades.
We evaluated mortality on the first day of life by the hour (0, 1, …, 23 h), and in the first hour by 5-min block (0-4, 5-9, …, 55-59 min) using data on cause of death for 15,690 infants in Canada from 1981 to 2012.
Infant mortality on the first day declined from 2.60 per 1000 in the 1980s to 1.26 in the 2000s. The decline was greater at 6-23 h than at 0-5 h of life, and among infants with congenital anomalies compared with prematurity and birth asphyxia.
Infant mortality is highest on the first day of life. More focus on prematurity and birth asphyxia in the first 5 h of life is needed to improve infant mortality.
按分钟和小时评估出生第一天的死亡率，并研究过去三十年主要死因的变化情况。
我们利用1981年至2012年加拿大15690例婴儿的死因数据，按小时（0、1、…、23小时）以及在第一个小时内按5分钟时段（0 - 4、5 - 9、…、55 - 59分钟）评估出生第一天的死亡率。
出生第一天的婴儿死亡率从20世纪80年代的每1000例2.60例降至21世纪初的1.26例。出生后6 - 23小时的死亡率下降幅度大于0 - 5小时，先天性异常婴儿的死亡率下降幅度大于早产和出生窒息婴儿。
婴儿死亡率在出生第一天最高。为了降低婴儿死亡率，需要更加关注出生后前5小时内的早产和出生窒息问题。
