Sudden unexplained death in childhood (SUDC) is defined as the unexplained death of a child over the age of 12 months. The National Coronial Information System (NCIS) Australia was used to access data for deaths of children aged 1 to 4 years over the period 2010 to 2014. Cases were classified as those in which the cause of death was determined and those in which the child died suddenly and unexpectedly, and the cause of death remained undetermined. Categorical information was extracted for each case to determine risk factors associated with the cause of death. The overall rate of death in Australian children aged 1 to 4 years and for whom coronial data was available from 2010 to 2014 was 9.69/100,000 children. A cause of death was determined in 87% of cases with the average rate of death in this group being 8.49/100,000. Death remained undetermined in 13% of cases. The study determined that the SUDC rate in Australian children aged 1 to 4 years was 0.02/100,000. However, this rate may be as high as 0.40/100,000 children should further investigation be undertaken. These children tended to be 18-20 months of age and male, with death occurring primarily while prone during a sleep period in cooler months, thus having similar characteristics to sudden infant death syndrome.
儿童突发性不明原因死亡（SUDC）定义为 12 个月以上儿童的不明原因死亡。澳大利亚国家尸检信息系统（NCIS）被用于获取 2010 年至 2014 年期间 1 至 4 岁儿童死亡的数据。病例分为死因确定的病例和儿童突然意外死亡且死因未确定的病例。对每个病例提取分类信息，以确定与死因相关的危险因素。2010 年至 2014 年期间，澳大利亚 1 至 4 岁儿童的总体死亡率为每 10 万名儿童 9.69 例。87%的病例死因确定，该组的平均死亡率为每 10 万名儿童 8.49 例。13%的病例死因未确定。研究确定，澳大利亚 1 至 4 岁儿童的 SUDC 发生率为每 10 万名儿童 0.02 例。然而，如果进行进一步调查，该比率可能高达每 10 万名儿童 0.40 例。这些儿童的年龄通常为 18-20 个月，且为男性，死亡主要发生在凉爽月份睡眠期间俯卧位，因此与婴儿猝死综合征具有相似的特征。
