Stanford Technology Analytics and Genomics in Sleep


The Stanford Technology Analytics and Genomics in Sleep (STAGES) study is a prospective cross-sectional, multi-site study involving 20 data collection sites from six centers including Stanford University, Bogan Sleep Consulting, Geisinger Health, Mayo Clinic, MedSleep, and St. Luke's Hospital. The project has collected data on 1,500 adult/adolescent patients evaluated for sleep disorders, including:

  • Objective nocturnal sleep polysomnography (PSG) recordings (EEGs, chin and leg EMGs, nasal and oral breathing, chest movements, leg movements, position, EKG). This is the gold standard for sleep evaluation in sleep clinics.
  • Comprehensive subjective sleep symptoms assessment through an on-line sleep questionnaire called the Alliance Sleep Questionnaire (ASQ, developed over 5 years by 5 academic institutions). The questionnaire also includes key medical history questions.
  • Continuous actigraphy over several weeks to get untransformed activity counts (a Huami/Xiaomi actigraph device has been identified and validated against PSG and clinical gold standard Actiwatch)
  • 3-D facial scans to extract craniofacial features predictive of sleep apnea (not available on NSRR)
  • On-line neuropsychological assessments and psychovigilance tests (impact of sleep disorders)
  • Medical record data (not available on NSRR)

All data, samples, analytic tools, and supporting documentation will be made publicly available for use by any interested researcher, provided a request is submitted to the National Sleep Research Resource and approved.

The National Sleep Research Resource is grateful to the STAGES team for sharing these data.

Protocols and manuals


July 2023

  • Add note in About section about unavailability of facial scan and medical record data

June 2023

  • Remove PSGs from Mayo Clinic site due to EDF/annotation conversion issues. The NSRR recommends not using Mayo Clinic PSG data until they are reprocessed by the STAGES data contributor at a later date.
