S365: A Multicenter Longitudinal Cohort of Sleep Health

The goal of this observational study is to explore the long-term health outcomes of sleep disorders in adults aged 18 and older, as well as to identify associated biomarkers and risk factors. The main questions it aims to answer are:

* What are the long-term health risks associated with sleep disorders, such as cognitive decline, cardiovascular diseases, or metabolic conditions?
* Are there specific biomarkers or patterns that can predict the onset or progression of sleep disorders?

Participants diagnosed with sleep disorders (e.g., insomnia, sleep apnea) or identified as healthy controls will undergo home-based sleep monitoring and complete clinical assessments at baseline and during follow-ups over a 3-year period. Biological samples, including blood and stool, will also be collected to analyze potential biomarkers. Data will be used to develop predictive models for sleep disorder risk and outcomes.

Sleep is a vital component of overall health and well-being. However, millions of people suffer from sleep disorders, including insomnia, sleep apnea, and parasomnias, which significantly impact their quality of life and contribute to various health conditions such as cardiovascular disease, diabetes, and cognitive decline. This comprehensive observational study aims to revolutionize the understanding, diagnosis, and treatment of sleep disorders through advanced data collection, innovative technology, and cutting-edge analysis.

Study Objectives

This study focuses on building a multicenter, multidimensional clinical sample database and integrating it with big data analysis platforms to address critical gaps in sleep disorder management. Key objectives include:

1. Establishing a Standardized Database: Creating a repository of clinical, biochemical, and imaging data to better understand sleep disorders and their associated conditions.
2. Developing Predictive Models: Identifying biomarkers and risk factors to develop models for early diagnosis and risk prediction.
3. Improving Intervention Outcomes: Evaluating the long-term effects of various interventions on sleep disorders to inform personalized treatment plans.
4. Promoting Preventive Measures: Building comprehensive early warning systems for sleep disorders to prevent progression and related health issues.

Key Research Questions

* What are the biological, behavioral, and environmental factors that contribute to sleep disorders?
* How do sleep disorders progress over time, and what health risks are associated with them?
* Can specific biomarkers predict the onset or severity of sleep disorders?
* What are the long-term effects of various interventions, and how can they be optimized for individual patients?

Study Participants

This study includes two participant groups:

1. Sleep Disorder Patients: Individuals diagnosed with conditions like insomnia, sleep apnea, and parasomnia. Diagnosis is conducted through advanced techniques like polysomnography (PSG).
2. Healthy Control Group: Individuals with no reported sleep issues, serving as a comparison baseline.

Eligibility Criteria:

* Adults aged 18 or older.
* Willing to provide informed consent and participate in the study for up to three years.
* Exclusion criteria include severe mental illnesses, pregnancy, or certain medical conditions that might interfere with the study.

Study Design

This is a non-interventional cohort study designed to gather extensive, high-quality data over time. It employs both retrospective and prospective approaches to ensure comprehensive insights into sleep disorders.

1. Data Collection Methods:

   * Clinical Assessments: Participants provide demographic, lifestyle, and medical history information through standardized questionnaires.
   * Biological Samples: Blood and stool samples are collected for biochemical and microbiome analyses.
   * Sleep Monitoring: State-of-the-art technologies are used to track sleep patterns and physiological parameters.
2. Follow-Up Plan:

   * Participants are monitored at baseline and followed up annually for three years (12, 24, and 36 months).
   * Follow-ups include sleep assessments, biological sampling, and health status updates.
3. Technology Utilized:

   * Sleep Monitoring Mats: Non-contact devices placed under pillows or mattresses to measure heart rate, breathing patterns, and sleep cycles.
   * Wearable Devices: Devices like EmbracePlus and pulse oximeters continuously monitor physiological metrics, including blood oxygen levels and activity patterns.
   * Data Management Platforms: A centralized system ensures secure data storage and facilitates seamless analysis across multiple centers.

Study Outcomes

1. Primary Outcomes:

   * Identification of long-term health risks linked to sleep disorders, such as cognitive impairment, cardiovascular disease, and metabolic dysfunctions.
   * Evaluation of disease progression in participants over the study period.
2. Secondary Outcomes:

   * Discovery of biomarkers that can serve as early warning signals for sleep-related health issues.
   * Development of personalized risk models to guide early interventions.
3. Exploratory Outcomes:

   * Insights into the microbiome's role in sleep disorders through stool sample analysis.
   * Advanced imaging and EEG data to explore brain activity changes in sleep-disordered individuals.
