About this study

The aims of this study are to determine the types and severity of previously undiagnosed sleep deficiencies in otherwise healthy Somali Americans, apply a research framework to define psychosocial, behavioral, environmental, and biological mechanisms mediating sleep deficiencies in Somali Americans, and examine the relationship between sleep deficiencies and increased blood pressure in Somali Americans.

Interventions

• Diagnostic Test: 24 hour blood pressure (BP) monitoring — 24-hour ambulatory BP measuring device and blood pressures will be measured every 20 minutes to half hour
• Diagnostic Test: Polysomnography — Measurements will include electroencephalogram, electromyogram, electrooculogram, electrocardiogram, breathing patterns of chest and abdomen, nasal and oral airflow and oxygen saturation. Sleep stages and apneas will be scored in accordance with validated American Academy of Sleep Medicine standards.

Primary outcomes

• Undiagnosed sleep deficiency-short sleep (1 night sleep study, approximately 8-9 hours)
• Undiagnosed sleep deficiency-insomnia (1 night sleep study, approximately 8-9 hours)
• Undiagnosed sleep deficiency-obstructive sleep apnea (OSA) (1 night sleep study, approximately 8-9 hours)
• Disrupted sleep (1 night sleep study, approximately 8-9 hours)
• Blood pressure (BP) during wakefulness (Day 2)
• Blood pressure (BP) during sleep (Day 2)
