  1. Sleeping position and sudden infant death syndrome in Norway 1967-91.

    Article - En anglais


    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=34799) 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.


    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.
