Your zip code may be worsening your sleep apnea — and your heart health

A new study out of Cleveland Clinic reveals that neighborhood disadvantage significantly shapes how severe obstructive sleep apnea (OSA) gets — and how deadly it can become. Analyzing data from over 72,000 adults who underwent diagnostic sleep studies between 2005 and 2021, researchers found that patients living in the most economically deprived neighborhoods experienced worse oxygen drops during sleep, independent of how often they stopped breathing at night.

The cardiovascular stakes are real: patients in the most disadvantaged neighborhoods faced a 22% higher risk of major adverse cardiovascular events (MACE) — including heart failure, stroke, atrial fibrillation, and coronary artery disease — compared to those in the least disadvantaged areas.

By the Numbers

• 72,443 adults analyzed from the Cleveland Clinic sleep registry
• 22% higher MACE risk for patients in the most vs. least disadvantaged neighborhoods
• 41% increased MACE risk associated with ADI quintile 4 in the type III sleep testing cohort
• Median follow-up: 5.6 years (polysomnography cohort), 2.8 years (type III cohort)

Why it matters: These findings highlight a critical but often overlooked intersection of social determinants of health and cardiovascular risk. Incorporating neighborhood-level socioeconomic data into cardiovascular risk assessments could help clinicians identify high-risk OSA patients earlier and address persistent health disparities.
