Our study suggests that South Florida Hispanic veterans with OSA evaluated in a sleep clinic show poor CPAP adherence. Insomnia and poor early use predicted poor adherence overall. Larger prospective studies with other race-ethnic groups are needed to determine the role of ethnicity and race in CPAP adherence among US veterans with OSA.

Insomnia symptoms, OSA, and subsequent poor sleep quality are prevalent in Parkinson's disease. In this single-center, exploratory study, we found that insomnia and poor sleep quality, but not OSA, play important roles in determining overall quality of life for patients with this disease. Clinical trial registered with www.clinicaltrials.gov (NCT02034357).

Study Objectives:There is a paucity of information on the epidemiology of sleep disorders among US Hispanics. This study describes the frequency of sleep disordered breathing (SDB) risk, insomnia complaints, poor sleep quality, and daytime somnolence in a clinical cohort of ethnically diverse US Hispanics living in South Florida. Methods: We explored the presence of sleep disorders in a cohort of Hispanics seen at primary care, pulmonary, and sleep clinics at the University of Miami and Miami Veterans Affair Medical Center. Participants completed validated questionnaires, evaluating risk of SDB, presence of insomnia symptoms, sleep quality, and daytime sleepiness. Polysomnography was completed on the majority of the sleep clinic participants. Results: Participants (N = 282; 62% male; mean age 54 ± 15 years; mean BMI 31 ± 6 kg/m 2 ) included Hispanics of Cuban, Puerto Rican, Central/South American, and Caribbean heritage. Excessive daytime sleepiness was noted by 45% of participants. Poor sleep quality was reported by 49%; 76% screened high risk for SDB, and 68% had insomnia symptoms. Sleep disorders were more commonly reported in sleep clinic participants; however, 54% of non-sleep clinic participants were high risk for SDB, 35% had insomnia complaints, 28% had poor sleep quality, and 18% reported daytime sleepiness. Conclusions: Sleep disorders (including SDB) are common in clinical samples of Hispanics in South Florida. These fi ndings highlight the urgent need for linguistically relevant and culturally responsive screening, awareness and education programs in clinical sleep medicine among US Hispanics.
