Sleep Disordered Breathing, Insomnia Symptoms, and Sleep Quality in a Clinical Cohort of US Hispanics in South Florida

Abstract

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.

Sleep Quality Among Latino Farmworkers in North Carolina: Examination of the Job Control-Demand-Support Model

“…Fewer than 17% reported poor quality sleep during the past month (PSQI > 5). The mean PSQI scores is lower, indicating better sleep quality, than other samples of young adult English-speaking Latinos from San Diego County, California (62), English- and Spanish-speaking Mexican-born and U.S.-born Latinos of Mexican descent in San Diego County (mean age of 41) (63), and young adult English-speaking Mexican Americans from a general medicine clinic in Miami, Florida (64). The PSQI scores of young to middle-age adult non-Latinos are also higher than those in our analysis (63, 65).…”

Sleep-disordered Breathing in Hispanic/Latino Individuals of Diverse Backgrounds. The Hispanic Community Health Study/Study of Latinos

“…However, this study did not use a representative frame. Other questionnaire surveys that have compared the prevalence of SDB symptoms between Hispanic and non-Hispanic individuals have provided inconsistent results, with some studies reporting no differences (26-28) and others reporting a higher prevalence in Hispanics compared with other groups (28,29).…”

Sleep Quality among Hispanics of Mexican Descent and Non-Hispanic Whites: Results from the Sleep Health and Knowledge in US Hispanics Study

“…It is important to notice, that there have been very few researches exploring thoroughly sleep disturbances among different ethnic groups and furthermore, studies among Hispanics are almost nonexistent. With few exceptions, US Hispanics are only a small proportion of epidemiologic studies, although it is the second largest ethnic group in the United States [16]. In a study evalu- [36].…”

“…Furthermore, sleep disorders are linked to poor mental and physical health and directly impact quality of life [4][5][6][7][8]. Prior studies have suggested ethnic differences in sleep-related disorders such as obstructive sleep apnea, restless legs syndrome, insomnia, and in sleep continuity and architecture [9][10][11][12][13][14][15][16][17][18][19]. The majority of sleep research has been conducted in Non-Hispanic Whites (NHW), and to a lesser extent in African-Americans and Asians.…”
