Abstract
INTRODUCTION: Epidemiological studies on obstructive sleep apnoea syndrome (OSAS) in Asia, South East Asia in particular, are few. The EPSASIE study aimed to determine the prevalence of OSAS in an adult Vietnamese population and to describe its characteristics. METHODS: This is a prospective, observational, multicenter study. Nocturnal ventilatory polygraphy (PV) or polysomnography (PSG) were performed in patients having symptoms evocative of the SAS syndrome and an index of respiratory events (IER)>10/h or>25 in one hour, measured by RU Sleeping. RESULTS: A total of 667/750 validated questionnaires were received. The mean age of the study population was 44±12 years with a mean body mass index of 21.6±5.2kg/m2. PV or PSG were performed on 93 subjects after positive screening by RU Sleeping. OSAS with an apnoea-hypopnoea index (AHI)>5 was found in 57 subjects (8.5%) and in 35 subjects with AHI>15 (5.2% of cases). CONCLUSION: The prevalence of OSAS is quite high in the Vietnamese population and comparable with current literature data.
