Is this trial a fit for you?
✓Likely a good fit
Adults in China from community settings, or with hypertension, COPD, diabetes, cardiovascular disease, or other OSA-related conditions, who can consent and complete questionnaires.
✕Probably not a fit
Individuals unlikely to have OSA or who do not complete the questionnaires or tests may receive no direct benefit.

What this trial studies
This prospective observational study in China aims to determine the prevalence and clinical features of obstructive sleep apnea-hypopnea syndrome in community residents, patients with specific diseases, and special populations. It uses random sampling to select participants and administers standardized screening questionnaires, with a subset undergoing PSG or portable sleep monitoring to confirm results. The study applies cluster sampling for communities and computer-based randomization to classify high- and low-risk individuals for further testing. It seeks to evaluate the value of different screening tools across diverse populations. Recruiting is ongoing with 2,185 participants enrolled to date across multiple centers.
Why it matters
Potential benefit: If successful, the study could improve understanding of who is at risk for OSA in diverse groups and help tailor screening approaches.
How similar studies have gone: Previous studies using diverse populations and questionnaire-based screening coupled with objective testing have shown meaningful insights into OSA prevalence and screening performance.
