Improvements in infant mortality (death less than 1 year of age) have been experienced by the United States and Alaska over the past decade. The decline in the Alaska neonatal mortality (death less than 28 days of age) rate has been the major factor in our improved infant mortality rate. Alaska's neonatal mortality rate is one of the lowest in the U.S. However, postneonatal mortality (28 days to 1 year of age) rate has not declined and is one of the highest in the U.S. In this study we used vital statistics records to examine socio-demographic and inter-regional factors that may help to explain Alaska's apparently high postneonatal mortality rate. The study population consisted of all live born infants in Alaska for 1975 to 1985, who died in infancy. The Alaska neonatal mortality rate has been lower, but postneonatal mortality rate has been higher than the U.S. average for the period under consideration (p less than .05). Comparison of alaska postneonatal mortality rate from 1975 to 1985 with the U.S. found Alaska Non-natives have higher postneonatal mortality rates than U.S. White, and Alaska Native have higher postneonatal mortality rates than other U.S. minorities. The rural areas of Alaska have a higher postneonatal mortality rate than urban areas, a phenomenon also observed for the U.S. as a whole.
在过去十年中，美国和阿拉斯加的婴儿死亡率（1岁以下死亡）有所改善。阿拉斯加新生儿死亡率（28天以下死亡）的下降是我们婴儿死亡率改善的主要因素。阿拉斯加的新生儿死亡率是美国最低的之一。然而，出生后死亡率（28天至1岁）并未下降，是美国最高的之一。在本研究中，我们使用生命统计记录来研究可能有助于解释阿拉斯加明显较高的出生后死亡率的社会人口和地区间因素。研究人群包括1975年至1985年在阿拉斯加出生并在婴儿期死亡的所有活产婴儿。在所考虑的时期内，阿拉斯加的新生儿死亡率较低，但出生后死亡率高于美国平均水平（p小于0.05）。将1975年至1985年阿拉斯加的出生后死亡率与美国进行比较发现，阿拉斯加非本地人出生后死亡率高于美国白人，阿拉斯加原住民出生后死亡率高于其他美国少数族裔。阿拉斯加农村地区的出生后死亡率高于城市地区，美国整体也观察到了这一现象。
