Large Sleep Survey and Recording Database

From mid 2015, we will work with the National YaJianKang Association, a non-profit organization under the State Administration of Traditional Chinese Medicine of P. R. China, to conduct a sleep quality survey in 100 Chinese cities. The sleep quality of 10,000 residents will be surveyed in each city, leading to a large database of one million people sleep quality survey. In addition, about 30% of those surveyed will have an ECG-based overnight sleep monitoring to provide quantitative sleep quality assessment, as well as sleep disorder (e.g., sleep apnea and insomnia) screening.
