How daily life and sleep affect heart and metabolic health in Black adults
Multilevel Determinants of Circadian Factors and Sleep Disruption: Implications for Cardiometabolic Health Among African-Americans
This project looks at how neighborhood, work, and personal factors shape sleep timing and quality and how those sleep patterns relate to blood pressure and metabolism in African-American adults.

What this research studies
You would join a well-characterized group of African-American adults in the Atlanta area and be followed over time with repeated measurements. Researchers will track your sleep timing and quality using wearable monitors, screen for sleep apnea, and collect blood pressure and metabolic health measures at multiple visits. They will also gather information about your neighborhood, work schedules, socioeconomic factors, and personal resilience to see which social or environmental factors relate to disrupted sleep. The team will combine these data to understand pathways linking circadian misalignment and sleep problems to cardiometabolic health.
Who could benefit from this research
Good fit: Ideal participants are African-American adults (age 21 and older), especially those living in or near Atlanta, willing to wear sleep monitors and provide blood pressure and blood samples over time.
Not a fit: People who are under 21, not African-American, unable or unwilling to complete sleep monitoring or follow-up visits, or who live far from the Atlanta area may not directly benefit from participating.
Why it matters
Potential benefit: If successful, this work could reveal modifiable sleep and environmental factors to help reduce heart and metabolic disease risk in African-American adults.
How similar studies have performed: Previous research has linked poor sleep and sleep apnea to cardiometabolic disease, but few studies have combined repeated sleep monitoring with neighborhood and resilience measures specifically in African-American populations, so this approach is relatively novel.
