Abstract

Background: Assessing sleep-disordered breathing (SDB) in aged or disabled populations is difficult. Aims: To validate a multivariable apnea risk prediction index (MAPI) in stroke survivors and estimate SDB prevalence (apnea-hypopnea index ≥10) in a community-based stroke cohort. Methods: Self-reported sleep apnea symptoms, demographic and anthropometric data were obtained from a hospital-based (SCOPES II, n = 152) and a community-based (NEMESIS, n = 431) cohort at about 3 years after stroke. Logistic regression models for prediction of SDB using the MAPI were validated with home-based nocturnal polygraphic data recordings obtained in 74 SCOPES II participants. Results: NEMESIS subjects (med..
