Hypothesis
Does the STOP-Bang questionnaire effectively identify high-risk individuals for obstructive sleep apnea and predict cardiovascular morbidity?
Conclusion
A significant proportion of individuals at high risk of obstructive sleep apnea remain undiagnosed, and this group shows a higher burden of cardiovascular morbidity.
Supporting Evidence
- Approximately 6.7% of participants were classified as high-risk for obstructive sleep apnea.
- The high-risk group had a significantly higher prevalence of cardiovascular morbidity at 11.9%.
- Only 0.6% of participants reported being diagnosed with obstructive sleep apnea.
- The STOP-Bang high-risk group was an independent predictor of cardiovascular morbidity.
Takeaway
Many people in South Korea who are at high risk for sleep apnea don't know they have it, and this can lead to heart problems.
Methodology
Data from the Korea National Health and Nutrition Examination Survey was analyzed, focusing on participants aged 40 and older who completed the STOP-Bang questionnaire.
Potential Biases
Potential confounding factors related to cardiovascular risk may not have been fully accounted for.
Limitations
The study may overestimate the gap between suspected and confirmed OSA cases, and it only includes participants aged 40 and older.
Participant Demographics
Participants were adults aged 40 and older from the general population of South Korea.
