Objectives:
The impact of pregnancy on sleep quality and sleep disordered breathing (SDB) is of interest due to concerns of an impact on maternal, intra-uterine and neonatal health. The SDB sub-study of the Nulliparous Pregnancy Outcomes Study (NuMoM2b) provided a large cohort of single gestational women who underwent home sleep apnea testing (HSAT) to evaluate for SDB. To evaluate changes in sleep during pregnancy, a secondary analysis of this data utilizing cardiopulmonary coupling (CPC) was performed.
Conclusion:
The sleep parameters of main interest the apnea hypopnea index (AHI), the sleep quality index (SQI) and sleep duration were all adversely impacted as gestation progressed (p<0.001).
Practical Significance:
The SleepImage method uses simple portable photoplethysmography and is low-cost, it is more convenient than the conventional method (HSAT) and offers the opportunity to monitor sleep during pregnancy as multiple tests can be conducted in a patient-friendly sleep environment, such as the patient’s own home.
