This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The physiological basis underlying the decline in the incidence of SIDS associated with changing the sleep position from prone to supine remains unknown. Recently, we have proposed that in term infants, prone position -induced diaphragm dysfunction contributes to the increased incidence of SIDS in prone vs. supine position. The purpose of this study is to look at the diaphragm dimensions and function in supine and prone positions and their association with Sudden Infant Death Syndrome.
