Design outcomes

Primary

MeasureTime frame
The primary outcome is the change in sleep quality measured by the Garmin Sleep Score between baseline and 12 months postoperatively.

Secondary

MeasureTime frame
Secondary outcomes include changes in objective sleep parameters (total sleep time, sleep efficiency, sleep latency, REM sleep, nocturnal awakenings, SpO2, heart rate variability, and sleep timing parameters), changes in subjective sleep measures (PSQI, ESS, HADS, sleep diary), comparison between objective and subjective sleep measures, and associations between sleep quality and postoperative weight loss and quality of life.
