OBJECTIVE
To investigate, in a population based national study, the association between sleeping position of infants and the occurrence of sudden infant death syndrome (SIDS).
DESIGN
A retrospective survey and registry based ecological study. A questionnaire based surveillance of sleeping position was obtained in a random sample (n = 34,799) and surveillance of SIDS was based on all infants born in Norway 1967-91, surviving the perinatal period. Variables studied from the questionnaire were usual sleeping position (placed), breast feeding at 3 months, and maternal smoking in pregnancy, and from the Medical Birth Registry maternal age, birth order, and birth weight.
RESULTS
Proportion of infants sleeping prone increased from 1970 (7.4%) to 1989 (49.1%) and dropped in 1990 (26.8%) and 1991 (28.3%). Occurrence of SIDS increased from 1970 (1.1/1000) to 1989 (2.0) before dropping in 1990 and 1991 (1.1). IMPLICATION AND RELEVANCE OF RESULTS: A cause effect relationship between prone sleeping and SIDS as suggested in previous studies is supported by the present; and so far only, national study of infants' sleeping position.
目的
在一项基于全国人口的研究中，调查婴儿睡眠姿势与婴儿猝死综合征（SIDS）发生之间的关联。
设计
一项基于回顾性调查和登记的生态学研究。对一个随机样本（n = 34,799）进行了基于问卷的睡眠姿势监测，而对SIDS的监测则基于1967 - 1991年在挪威出生且度过围产期的所有婴儿。从问卷中研究的变量包括通常的睡眠姿势（放置方式）、3个月时的母乳喂养情况以及孕期母亲吸烟情况，从医疗出生登记处获取的变量包括母亲年龄、产次和出生体重。
结果
婴儿俯卧睡眠的比例从1970年的7.4%上升至1989年的49.1%，并在1990年（26.8%）和1991年（28.3%）下降。SIDS的发生率从1970年的1.1/1000上升至1989年的2.0，随后在1990年和1991年下降至1.1。结果的意义和相关性：本研究支持了先前研究中提出的俯卧睡眠与SIDS之间的因果关系；而且到目前为止，这是唯一一项关于婴儿睡眠姿势的全国性研究。
