Sleep during the week before labor: relationships to labor outcomes.

This correlational study was conducted to examine the relationship between maternal sleep during the nights prior to the onset of labor and labor outcomes of length, type of delivery, and maternal perceptions of labor. Subjects (N = 99) were drawn from childbirth education classes at a women's hospital in the southeastern United States. Subjects completed the Visual Analog Sleep Scale each morning, beginning two weeks prior to their due dates. Following delivery, subjects completed the Perception of Labor and Delivery Scale, and researchers gathered data about their labors. These women reported poor sleep effectiveness coupled with high sleep disturbance; however, there were no significant correlations between sleep quality and length of labor or maternal perceptions of labor for either the night, or the week, prior to the onset of labor. This finding leads us to question the view that disturbed prenatal sleep will interfere with the progress of labor and lead to more cesarean sections.
