Sleep Study Questions

1) Has anyone got a link to the study in which they studied infants in sleep clinics on their tummies, and recorded the number of times they turned their head, the percentage of time they spent with their head in various positions, and the percentage of time spent with obstructed or compromised breathing.

2) Since BTS, has anyone compared the number of times an infant on its back in sleep turns its head as opposed to an infant laid on its tummy?

Perhaps this is a source of the type of information you requested. Dr. Monique L'Hoir at Wilhelmina Children's Hospital, PB 18009, 3501 CA Utrecht, The Netherlands, did her thesis work on SIDS and had a poster on this last week in Rouen at the SIDS '98 meeting. Her poster (#131) suggests that there is "a different rate of motor development of boys in comparison with girls, resulting in earlier and more frequent turning to the risk carrying prone position, in particular when this occurs for the first time."

I do not have any information in regard to the second question. In regard to
the first question, I think you are referring to the study by Waters et al in
Journal of Pediatrics, Vol 128, pg 616-625, 1996.

Hope this is helpful.
