Predictors of De-novo Development of Obstructive Sleep Apnea in Pregnancy
Summary
This study seeks to understand the physical, physiologic and biologic features that predispose a woman to the development of obstructive sleep apnea once they are exposed to the cardiopulmonary and metabolic physiological changes of pregnancy. Knowing these specific predictive factors can help identify a population at risk and guide clinicians to develop suitable targeting screening strategies.
Description
Patients will be recruited from multiple community and hospital-based practices that care for pregnant women. Subjects will have:
1. measurements of body composition
2. anthropometric measures
3. sleep and mood questionnaires
4. Home sleep studies
5. blood testing for biological markers
6. salivary testing for hormonal markers
7. pulmonary function tests and upper airway patency measurements
Women without sleep apnea at enrollment will then be followed longitudinally for the development of obstructive sleep apnea during pregnancy with repeat assessment during their third trimester. Women diagnosed with sleep apnea at enrollment will have no further assessment in late pregnancy.
Monetary incentives will also be issued at data collection points. Subjects will receive small gift incentives such as baby-related items.

Cardiovascular Variability and Heart Rate Response Associated With Obstructive Sleep Apnea
Obstructive sleep apnea is often associated with microarousals and a stimulation of the sympathetic nervous system. The knowledge of this autonomic activation may help understanding the in...

The Effect of Obstructive Sleep Apnea Treatment on Dizziness, Vertigo
Obstructive Sleep Apnea may cause dizziness or vertigo through hypoxia of the vestibular nuclei in the brain. Treating sleep apnea may improve dizziness or vertigo.

Medical and Biotech [MESH] Definitions
Sleep Apnea, Central
A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)
Sleep Apnea Syndromes
Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
Sleep Disorders, Intrinsic
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Sleep Apnea, Obstructive
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
Obesity Hypoventilation Syndrome
HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.
