Welcome to the Sleep Special Interest Group (SIG),

The goal of the Sleep SIG is to provide a forum to promote the dissemination of sleep and circadian data and their relationship to other health attributes in the Hispanic Community Health Study/ Study of Latinos (HCHS/SOL). We hope to identify and facilitate new analyses and manuscripts from this rich self-reported and objective data, as well as to stimulate new ancillary studies. We welcome members with a wide range of expertise and investigators at any stage in their careers.

The Sleep SIG meets on the third Wednesday of every other month at 4pm Eastern / 1pm Pacific.

HCHS/SOL is a cohort study of 16,415 Hispanic/Latino adults aged 18-74 years from randomly selected households in four US cities (Chicago, Miami, Bronx, San Diego) with baseline clinic examination (2008-2011), yearly telephone follow-up assessments, and ongoing second clinic examination (2014-2017). As part of the HCHS/SOL baseline exam, Sleep history and symptoms were assessed using the Sleep Heart Health Study Sleep Habits Questionnaire and the Epworth Sleepiness Scale (ESS). Participants were instructed on use of a sleep apnea monitor for overnight recording (ARES Unicorder). This self-applied device measures airflow using a nasal pressure cannula and transducer, hemoglobin oxygen saturation and pulse rate (reflectance oximetry), head movement and position (actigraphy), and a microphone to record snoring levels. Sleep records (n=14,400) were scored at a central sleep reading center. Certified polysomnologists manually edited artifacts, identified periods of sleep, and annotated each respiratory event with its associated oxyhemoglobin desaturation. Respiratory events were identified as a 50% or greater reduction in airflow lasting greater than or equal to 10 seconds.

The HCHS/SOL Ancillary Study “Sueño” (2010-2013) enrolled 2,252 HCHS/SOL participants <65 years of age, and were asked to wear an Actiwatch device for 7 days.
