70 overweight or obese adults with sleep disorders will be recruited for this study, in which the investigators aim to compare wrist actigraphy with polysomnography (PSG) for sleep monitoring. It is to evaluate the applications of Jawbone Up2 with the sleep parameters derived from this actigraphy.

As an observation study, it will recruit 70 overweight or obese patients with sleep disorders who meet the selection criteria: clinical records and AIS at a tertiary hospital. The patients will sign the informed consent form. The involved patients and doctors will receive related training.

These patients will receive the sleep monitoring from 21:00 to 6:00 in sleep monitoring laboratory in Ruijin Hospital. They will receive the PSG and Jawbone Up 2 sleep monitoring at the same time. Sleep parameters derived from actigraphy and PSG will be compared in multiple night recordings such as total sleep time, wake after sleep onset, sleep onset latency, awakening, sleep efficiency, total time in bed,. The aim is to assess the validation of actigraphy in overweight or obese patients with sleep disorders.
