Postneonatal deaths in Western Australia from 1970-78 were studied using a linked file of birth and death registrations. Postneonatal mortality fell during the period under study. The fall occurred in both male and female rates and the former were higher than the latter in all years. The infants at high risk during the postneonatal period were those born to unmarried teenage mothers residing in rural areas, especially if the infants were of low birthweight (less than 2500g). Multiple births and those infants born to mothers whose previous issues were over 4 were also at high risk. Infants born to Aboriginal mothers experienced a significantly higher rate of postneonatal mortality than those born to non-Aboriginal mothers. However, a significant improvement in the Aboriginal rate occurred between 1976 and 1977. The major causes of postneonatal death were sudden infant death syndrome, infections and congenital abnormalities.
利用出生和死亡登记的关联文件，对1970年至1978年西澳大利亚州的新生儿后期死亡情况进行了研究。在研究期间，新生儿后期死亡率有所下降。这种下降在男性和女性死亡率中均有出现，且所有年份中男性死亡率均高于女性。新生儿后期的高危婴儿是那些居住在农村地区的未婚青少年母亲所生的婴儿，尤其是出生体重低（低于2500克）的婴儿。多胞胎以及母亲之前生育超过4个孩子的婴儿也处于高危状态。原住民母亲所生婴儿的新生儿后期死亡率显著高于非原住民母亲所生婴儿。然而，1976年至1977年间，原住民的死亡率有了显著改善。新生儿后期死亡的主要原因是婴儿猝死综合征、感染和先天性异常。
