[Sleeping position and crib death in Norway]
1Barneklinikken, Haukeland sykehus.
Questionnaires to maternity hospitals in Norway in 1989 and 1991 showed that most units had changed the babies' sleeping position from the side position in the early 1970s, to predominantly prone in 1989, but back to the side position between 1989 and 1991. Parallel with these changes the incidence of sudden infant death increased steadily from 0.93 per 1,000 live births in the early 1970-74 to 2.4 per 1,000 in 1989, and dropped dramatically to 1.4 per 1,000 in 1990. It is assumed that parents adopt the sleeping position preferred in the maternity ward, and the study therefore supports the theory that the prone position significantly increases the risk of sudden infant death.
