Three southern New Zealand health districts had a postneonatal mortality rate of 8.1 per 1000 livebirths and a postneonatal sudden infant death syndrome (SIDS) mortality rate of 6.3 per 1000 livebirths for the period 1979-1984. This is one of the highest reported rates of SIDS. The 429 postneonatal deaths occurring during the period were assigned to one of four groups: unpreventable (n = 52), possibly preventable non-SIDS (n = 45), SIDS with minor abnormalities at necropsy or premorbid symptoms (n = 167), and SIDS with no abnormalities at necropsy or documented premorbid symptoms (n = 165). These groups were related to obstetric and perinatal data. For those infants classified as SIDS, the winter peak of deaths was particularly marked if death occurred after 3 months of age. These older SIDS deaths had more minor abnormalities at necropsy, a longer interval between time last seen or heard alive and found dead and more thymic petechiae.
1979年至1984年期间，新西兰南部的三个卫生区的新生儿后期死亡率为每1000例活产8.1例，新生儿后期婴儿猝死综合征（SIDS）死亡率为每1000例活产6.3例。这是报告的SIDS最高发生率之一。该期间发生的429例新生儿后期死亡被分为四组之一：不可预防组（n = 52）、可能可预防的非SIDS组（n = 45）、尸检时有轻微异常或病前症状的SIDS组（n = 167）和尸检时无异常或无记录病前症状的SIDS组（n = 165）。这些组与产科和围产期数据相关。对于那些被归类为SIDS的婴儿，如果死亡发生在3个月龄之后，冬季死亡高峰尤为明显。这些年龄较大的SIDS死亡病例在尸检时有更多轻微异常，从最后一次被看到或听到存活到被发现死亡的时间间隔更长，并且有更多胸腺瘀点。
