Observational Study of Obstructive Sleep Apnea Among Somali-Americans

This study is looking at obstructive sleep apnea (OSA), a condition where breathing repeatedly stops and starts during sleep. Researchers want to understand how OSA affects people of different ethnic backgrounds, especially Somali-Americans, and if there are differences between men and women. They will compare Somali patients with OSA to those without OSA, and to people of other ethnic groups, to find risk factors (like genes or body functions) that might lead to heart problems. The study aims to understand the unique sleep health of people of African descent. You can join if you are 18 or older and identify as Somali, African, Asian, or European. The study hopes to enroll 600 participants. The main goals are to measure how common OSA is and how severe it is over 10 years.

Study design
This is an observational study, meaning researchers will observe participants without giving a specific treatment. It aims to enroll 600 participants.
What's involved
You may undergo a sleep study (at home or hospital), physical exam, questionnaires, blood and urine tests, heart and arm artery ultrasounds, CT scan, DEXA scan, paced breathing test, cardiopulmonary test, and chemosensitivity test.
Compensation
Not stated in the trial record.
Follow-up
The study will assess the prevalence and severity of obstructive sleep apnea over 10 years.

What this trial measures

  • To assess the prevalence of obstructive sleep apnea10 years

    Measure the apnea-hypopnea index (AHI) to determine burden of obstructive sleep apnea. Based on the AHI, sleep apnea will be diagnosed if the AHI is ≥5 events/hour.

  • To determine the severity of obstructive sleep apnea10 years

    The severity of OSA is classified based on the AHI as follows: None/Minimal: AHI \< 5 per hour, Mild: AHI ≥ 5, but \< 15 per hour, Moderate: AHI ≥ 15, but \< 30 per hour, Severe: AHI ≥ 30 per hour.
