Assessment of Smartwatch SAMSUNG to Monitor Sleep Quality: an Observational Prospective Study - SleepEx2 Protocol

Completed

• Conditions: Sleep; Sleep Initiation and Maintenance Disorders; Health Status; Wearable Electronic Devices; Insomnia

• Registration Number: NCT06363656
• Lead Sponsor: University of Sao Paulo General Hospital

Brief Summary

The goal of this study is to learn if a smartwatch is effective to identify factors related to sleep quality and habits of adults (30 years old or more), enabling the improvement and/or creation of instruments to assess overall health status and sleep quality.

The main question it aims to answer is:

- Does the smartwatch application (software) indicate sleep habits and measure sleep quality in accordance to the standardized clinical instruments commonly used to assess sleep?

Detailed Description

Participants will answer questionnaires about overall health status, sleep quality and insomnia at the beginning, at 16 days follow-up, and at the end of the study. Participants must use the smartwatch for at least a 12-hour period that includes night time, during a minimum of 30 consecutive days.
