NCT06363656

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?

Outcome Measures

Primary Outcomes (1)

  • Concordance between the smartwatch application and clinical assessment

    Intraclass correlation coefficient calculated between sleep characteristics captured by the smartwatch and scores of all questionnaires

    1) at the beginning (start); 2) at the 16-days follow-up (middle); 3) at the 30-days follow-up (end).

Study Arms (1)

single-group

Participants who declare having problems with sleeping/insomnia

Device: Wears the smartwatch during the sleep time to capture sleep characteristics and answer questionaires

Interventions

* Synchronization of smartwatch with smartphone (internet connection) to send sleep characteristics captured by the application * Weight * Height * Body measurements (circumferences) * Questionnaires about overall health status * Pittsburgh Sleep Quality Index questionnaire * Insomnia Severity Index * Sleep Hygiene Index * Epworth Sleepiness Scale * NoSAS score (Neck, Obesity, Snoring, Age, Sex)
