Abstract: This pilot study will be a randomized cross-over repeated measures study of an intervention to prevent supine sleep in pregnancy. The aim of this study is to test the effectiveness of a new pillow designed to decrease the amount of time pregnant women spend sleeping on their back. This study will involve two conditions for each woman: one week using the new pillow and one week without the pillow, each ending with a night of overnight sleep monitoring. The sleep monitoring will (i) measure body position throughout the night to establish whether the new pillow is preventing back sleeping, and (ii) to determine if the pillow is comfortable and encourages better sleep. Importantly, we will (iii) perform fetal heart rate monitoring during the night to compare whether there are measurable differences in the baby's heart rate between these two settings. This study will help us to determine the impact of sleeping on your back during pregnancy, and whether we can encourage a safer sleeping position.
