ABSTRACT
PURPOSE: Portable sleep monitors may offer a convenient method to expand detection of obstructive sleep apnea (OSA), yet few studies have evaluated this technology in vulnerable populations. We therefore aimed to assess the feasibility and acceptability of portable sleep monitors for detection of OSA in a prediabetic, urban minority population. METHODS: We recruited a convenience sample of participants at their 12-month follow-up for a community-partnered, peer-led lifestyle intervention aimed to prevent diabetes in prediabetic and overweight patients in this prospective mixed-methods pilot study. All participants wore portable sleep monitors overnight at home. We qualitatively explored perceptions about OSA and portable monitors in a subset of participants. RESULTS: We tested 72 people, predominantly non-White, female, Spanish speaking, uninsured, and of low income. Use of portable sleep monitors was feasible: 100% of the monitors were returned and all participants received results. We detected OSA in 49% (defined as an Apnea-Hypopnea Index [AHI] >5) and moderate-severe OSA in 14% (AHI >15) requiring treatment in 14%. In 21 qualitative interviews, participants supported increased use of portable sleep monitors in their community, were appropriately concerned that OSA could cause progression to diabetes, and thought weight loss could prevent or improve OSA. CONCLUSIONS: Portable sleep monitors may represent a feasible method for detecting OSA in high-risk urban minority populations.

East Harlem has the highest diabetes mortality rate in New York City, NY. Using Community Based Participatory Research principles, the East Harlem Partnership for Diabetes Prevention-a community- academic partnership-formed to build community capacity with a goal to address health disparities in East Harlem. As part of prevention efforts, community partners chose to study the prevalence of obstructive sleep apnea and its relationship to pre-diabetes and progression to diabetes. However, community partners insisted any study of sleep apnea go beyond simple assessment to ensure the largely uninsured, minority population enrolled also have access to state of the art diagnosis and treatment. Through compromise and collaboration, the partnership developed a culturally appropriate and scientifically rigorous method to diagnose and treat sleep apnea as part of a novel research program.
