A survey of all infants dying from the Sudden Infant Death Syndrome (SIDS) in Tasmania from 1975 to 1981 showed an incidence of 4.4 per 1000 live births; SIDS comprised 68% of infant deaths. The peak incidence of death was at 3 months of age and the following factors were significant: male sex, gestation less than 38 weeks, birthweight less than 2500 g, unmarried mothers, maternal age below 24 years and unskilled fathers. Analysis of these factors in combination showed each to be independently significant. SIDS was more frequent in the southern and western regions of Tasmania, and there was a higher incidence of death in the colder months in infants over 13 weeks of age. The monthly incidence of SIDS was inversely proportional to the monthly mean temperature in Tasmania and directly proportional to monthly hospital admissions for respiratory infections and apnoea. However, admissions for apnoea were more common in infants under 14 weeks of age. From these observations it is suggested that cold and respiratory infections are associated with the onset of SIDS in older infants.
一项针对1975年至1981年塔斯马尼亚州所有死于婴儿猝死综合征（SIDS）的婴儿的调查显示，其发病率为每1000例活产中有4.4例；SIDS占婴儿死亡的68%。死亡的高峰发病率出现在3个月大时，以下因素具有显著性：男性、妊娠少于38周、出生体重低于2500克、未婚母亲、母亲年龄低于24岁以及父亲无技能。对这些因素进行综合分析表明，每一个因素都具有独立的显著性。SIDS在塔斯马尼亚州的南部和西部地区更为频繁，并且在13周龄以上婴儿的较寒冷月份死亡率更高。塔斯马尼亚州SIDS的月发病率与月平均气温成反比，与每月因呼吸道感染和呼吸暂停而住院的人数成正比。然而，呼吸暂停住院在14周龄以下婴儿中更为常见。从这些观察结果来看，有人提出寒冷和呼吸道感染与较大婴儿SIDS的发病有关。
