Cot death is the most important cause of death during the first year of life after the newborn period in Norway. A case control study was performed by sending questionnaires to 188 cot death parents and 475 control parents with infants matched for age, sex and time of birth. 76% of the cot death parents and 79% of the control parents completed the questionnaires. The male/female ratio of the babies in both groups was 64/36. The age distribution showed a peak between two and four months. 65% succumbed during the winter months. During the winter 32% died outdoors. This was true for only 16% of those who died during summer. A higher proportion of the cot death cases than the controls were premature (more than eight weeks). 78% of the cot death victims usually slept prone, whereas this was true for only 50% of the controls (p < 0.01). 91% of the cot death victims were found dead in a prone position. When comparing live babies during the first three months of life, significantly more cot death mothers than control mothers had stopped breastfeeding. A larger proportion of the cot death victims than the controls had had apparent life threatening events (p < 0.01). Foam mattresses were equally frequent in both groups.
在挪威，婴儿猝死是新生儿期过后一岁以内最重要的死亡原因。通过向188名婴儿猝死患儿的父母和475名对照婴儿的父母发放问卷进行了一项病例对照研究，对照婴儿在年龄、性别和出生时间上与病例匹配。76%的婴儿猝死患儿父母和79%的对照婴儿父母完成了问卷。两组婴儿的男女比例均为64/36。年龄分布在两到四个月之间出现峰值。65%的患儿在冬季死亡。在冬季，32%的患儿死于户外。而夏季死亡的患儿中这一比例仅为16%。婴儿猝死病例中早产（超过八周）的比例高于对照组。78%的婴儿猝死受害者通常趴着睡，而对照组中这一比例仅为50%（p<0.01）。91%的婴儿猝死受害者被发现死于俯卧位。在比较出生后前三个月的存活婴儿时，婴儿猝死患儿的母亲停止母乳喂养的比例显著高于对照婴儿的母亲。婴儿猝死受害者中发生过明显危及生命事件的比例高于对照组（p<0.01）。两组中使用泡沫床垫的频率相同。
