Screening for Obstructive Sleep Apnea Among Community Members, Patients with Specific Diseases, and Special Groups Across China

What this Trial Is About

Researchers are studying the prevalence and clinical features of obstructive sleep apnea-hypopnea syndrome OSAHS within various populations in China, including community residents, patients with specific diseases like hypertension and COPD, and special groups such as university staff and company employees. The study aims to understand how common OSA is in these groups and to evaluate the usefulness of different OSA screening questionnaires. Participants will complete a screening questionnaire, and some will be randomly selected to undergo either polysomnography PSG or portable sleep monitoring PM to confirm OSA diagnosis. This large-scale, multi-center observational study uses careful random sampling methods to ensure reliable and representative data across diverse populations. The study plans to enroll 100,000 participants for the questionnaire phase and 10,000 for the diagnostic monitoring phase. During the study, participants will answer questionnaires either by phone or in person, and selected individuals will receive sleep monitoring tests interpreted by professional sleep physicians. Data quality is maintained through rigorous checks and multiple imputation for missing data. The main outcomes measured include the Apnea-Hypopnea Index and lowest oxygen saturation, while secondary outcomes assess the diagnostic value of various OSA screening tools. The studys duration and follow-up extend through August 2027.
