Evidence shows an increasing association between (1) sleep disordered breathing and (2) maternal cardiovascular disease and in-hospital death. Snoring is a variant of obstructive sleep apnea (OSA) and OSA during pregnancy is associated with higher risks for cesarean delivery, gestational hypertension, preeclampsia and preterm delivery. It may also impact fetal outcomes negatively.

The purpose of this study is to determine whether sleep can be improved in pregnant women who snore by means of a midline traction oral appliance (OA) that opens the airway. This is an interventional study to objectively evaluate OA therapy on breathing during sleep as well as its effect on sleep quality. Pregnant women from all trimesters will be recruited. Each subject is expected to participate in the study for at least five (5) consecutive weeks. Home sleep recordings will be collected at three time points: T0 - Baseline prior to OA use for two consecutive nights; T1- first two consecutive nights wearing the OA; T2 - for two consecutive nights after 4 weeks of appliance use. In addition to the sleep studies performed at each of these time points, subjects will also complete several brief surveys. All participants will be given the opportunity to use their OAs after the 4 week period, and have their sleep recorded at 8 week intervals through the remainder of their pregnancies. Participants will get to keep and use their OAs after the study.\n\nPregnant women who snore (or otherwise have poor sleep), may qualify to participate in this study.

Many pregnant women experience snoring and poor sleep, which can be linked to health issues for both mother and baby. The oral appliance works by gently moving your lower jaw forward to open up your airway. Researchers will measure your sleep quality using home sleep recordings over five weeks to see if the appliance makes a difference. To join, you should be a pregnant woman between 18 and 45 years old who snores, and meet other health criteria. The study aims to enroll up to 20 participants.","After the initial 4-week period, you can continue to use the oral appliance and have your sleep recorded at 8-week intervals for the rest of your pregnancy.",111,"You would participate for at least five consecutive weeks, completing home sleep recordings at three different times and filling out surveys.
