在人口统计学和流行病学研究中，使用新生儿和新生儿后期死亡率作为内源性和外源性死亡率的替代指标是很常见的。本文所报告的结果表明，这种做法并不完全有效，也许需要重新制定新生儿死亡率的业务定义。研究表明，特定天数的内源性死亡率在生命的前18天占主导地位，代表特定天数的内源性和外源性死亡率模式的曲线在第18天左右收敛，而不是在第28天左右收敛。该研究还反对使用目前定义的新生儿后期死亡率作为外源性死亡率的替代指标。在第19天和第365天之间发生的所有可分类的婴儿死亡中，不到一半（44.5%）是由外生原因造成的。这项研究使用的新墨西哥州的出生和死亡数据相匹配，结果显示相当吻合。
Abstract The use of neonatal and postneonatal mortality rates as proxies for endogenous and exogenous mortality rates is common in demographic and epidemiological research. The results reported in this paper suggest that such a practice is not entirely valid and that, perhaps, a reformulation of the operational definition of the neonatal mortality rate is in order. The study shows that day‐specific endogenous mortality rates predominate during the first eighteen days of life and that curves representing the patterning of day‐specific endogenous and exogenous mortality rates converge at about the 18th day and not at about the 28th day. The study also warrants against the use of the postneonatal mortality rate, as currently defined, as a proxy for exogenous mortality. Of all classifiable infant deaths occurring between the 19th and the 365th day, less than half (44.5 per cent) are due to exogenous causes. The matched birth and death data from New Mexico used for this study are shown to correspond rather clo...
