Sleep is a biological necessity, and insufficient sleep and untreated sleep disorders are detrimental for health, well-being, and public safety. Healthy People 2030 includes several sleep-related objectives with the goal to improve health, productivity, well-being, quality of life, and safety by helping people get enough sleep. In addition to adequate sleep duration, healthy sleep requires good quality, appropriate timing, regularity, and the absence of sleep disorders. It is the position of the American Academy of Sleep Medicine (AASM) that sleep is essential to health. There is a significant need for greater emphasis on sleep health in education, clinical practice, inpatient and long-term care, public health promotion, and the workplace. More sleep and circadian research is needed to further elucidate the importance of sleep for public health and the contributions of insufficient sleep to health disparities.

Among pregnant women, Watch-PAT demonstrates excellent sensitivity and specificity for identification of obstructive sleep apnea, defined as AHI ≥ 5 on full PSG. Watch-PAT may overestimate RDI somewhat, especially at high RDI values.

Objective To assess the frequency of obstructive sleep apnea among women with and without hypertensive disorders of pregnancy. Design Cohort study. Setting Obstetric clinics at an academic medical center. Population Pregnant women with hypertensive disorders (chronic hypertension, gestational hypertension, or pre-eclampsia) and normotensive women. Methods Women completed a questionnaire about habitual snoring and underwent overnight ambulatory polysomnography. Main Outcome Measures The presence and severity of obstructive sleep apnea. Results Obstructive sleep apnoea was found among 21 of 51 women with hypertensive disorders (41%), but in only three of 16 women who were normotensive (19%, chi-square test, P = 0.005). Non-snoring hypertensive women typically had mild obstructive sleep apnea but >25% of snoring hypertensive women had moderate-to-severe obstructive sleep apnea. Among the hypertensive women, the mean apnea/hypopnea index was substantially higher in snorers than non-snorers (19.9±34.1 vs. 3.4±3.1, p=0.013) and the oxyhemoglobin saturation nadir was significantly lower (86.4±6.6 vs. 90.2±3.5, p=0.021). Among hypertensive women, after stratification by obesity the pooled relative risk for obstructive sleep apnea in snoring women with hypertension compared to non-snoring hypertension was 2.0 [95%CI 1.4–2.8]. Conclusions Pregnant women with hypertension are at high risk for unrecognised obstructive sleep apnea. While longitudinal and intervention studies are urgently needed, it would seem pertinent given the known relationship between obstructive sleep apnea and hypertension in the general population, that hypertensive pregnant women who snore should be tested for obstructive sleep apnea, a condition believed to cause or promote hypertension.
