Prevalence and correlates of obstructive sleep apnea among African Americans: the Jackson Heart Sleep Study.

ABSTRACT: Study Objectives:African Americans have been under-represented in obstructive sleep apnea (OSA) research. This study determined the prevalence and correlates of OSA overall and by sex among African Americans in the Jackson Heart Sleep Study. Methods:Participants (N = 852) underwent a type 3 in-home sleep apnea study, 7 day wrist actigraphy and completed standardized measurements and questionnaires. OSA was defined as an apnea-hypopnea index (AHI) of ?15, where hypopneas were defined as ? 4% associated desaturation. Physician diagnosis of OSA was self-reported. Logistic regression models were fit to determine the associations of demographics, socioeconomic status, sleep symptoms, actigraphy-based sleep, body mass index (BMI), and comorbidities with OSA. Results:Average age was 63.1 (standard deviation = 10.7), 66% were female, and mean BMI was 32.0 (6.9) kg/m2. Approximately 24% had an AHI ? 15; of those, 5% had a physician diagnosis of OSA. Prevalence of OSA increased across BMI categories, but not age groups. Men had a 12% higher prevalence of OSA compared with women, p < 0.01. Older age, male sex, higher BMI, larger neck circumference, and report of habitual snoring were independently associated with higher odds of OSA, all p < 0.05. Associations between sleep symptoms and OSA were similar for men and women. Sleepiness and waist circumference were not associated with OSA. Conclusions:There was a high prevalence of objectively measured but undiagnosed OSA in this sample of African Americans. Snoring, BMI, and neck circumference were important markers of OSA for men and women. Our results suggest that screening tools that incorporate information on sleepiness and waist circumference may be suboptimal in this population.

Project description:Study objectivesStudies have shown that psychosocial stressors are related to poor sleep. However, studies of African Americans, who may be more vulnerable to the impact of psychosocial stressors, are lacking. Using the Jackson Heart Study (JHS) baseline data, we examined associations of psychosocial stressors with sleep in 4,863 African Americans.MethodsWe examined cross-sectional associations between psychosocial stressors and sleep duration and quality in a large population sample of African Americans. Three measures of psychosocial stress were investigated: the Global Perceived Stress Scale (GPSS); Major Life Events (MLE); and the Weekly Stress Inventory (WSI). Sleep was assessed using self-reported hours of sleep and sleep quality rating (1 = poor; 5 = excellent). Multinomial logistic and linear regression models were used to examine the association of each stress measure (in quartiles) with continuous and categorical sleep duration (< 5 ("very short"), 5-6 h ("short") and > 9 h ("long") versus 7 or 8 h ("normal"); and with sleep quality after adjustment for demographics and risk factors (body mass index, hypertension, diabetes, physical activity).ResultsMean age of the sample was 54.6 years and 64% were female. Mean sleep duration was 6.4 + 1.5 hours, 54% had a short sleep duration, 5% had a long sleep duration, and 34% reported a "poor" or "fair" sleep quality. Persons in the highest GPSS quartile had higher odds of very short sleep (odds ratio: 2.87, 95% confidence interval [CI]: 2.02, 4.08), higher odds of short sleep (1.72, 95% CI: 1.40, 2.12), shorter average sleep duration (Δ = -33.6 min (95% CI: -41.8, -25.4), and reported poorer sleep quality (Δ = -0.73 (95% CI: -0.83, -0.63) compared to those in the lowest quartile of GPSS after adjustment for covariates. Similar patterns were observed for WSI and MLE. Psychosocial stressors were not associated with long sleep. For WSI, effects of stress on sleep duration were stronger for younger (< 60 y) and college-educated African-Americans.ConclusionsPsychosocial stressors are associated with higher odds of short sleep, lower average sleep duration, and lower sleep quality in African Americans. Psychosocial stressors may be a point of intervention among African Americans for the improvement of sleep and downstream health outcomes.

Project description:BackgroundEpidemiology of dysphagia and its drivers in obstructive sleep apnea (OSA) are poorly understood. The study aims to investigate the prevalence of dysphagia symptoms and their association with demographic and clinical factors in patients with OSA.MethodsPatients with OSA referring to an Academic Sleep Outpatient Clinic were enrolled in a prospective study. Demographic, clinical characteristics, and OSA symptoms were collected. All patients underwent home sleep cardiorespiratory polygraphy and the Eating-Assessment Tool questionnaire (EAT-10) to investigate dysphagia symptoms. Patients with a positive EAT-10 were offered to undergo a fiberoptic endoscopic evaluation of swallowing (FEES) to confirm the presence of dysphagia. FEES findings were compared with a healthy control group. Univariate and multivariate analyses were performed to assess predictors of dysphagia.Results951 patients with OSA (70% males, age 62 IQR51-71) completed the EAT-10, and 141 (15%) reported symptoms of dysphagia. Female gender (OR = 2.31), excessive daily sleepiness (OR = 2.24), number of OSA symptoms (OR = 1.25), anxiety/depression (OR = 1.89), and symptoms of gastroesophageal reflux (OR = 2.75) were significantly (p < 0.05) associated with dysphagia symptoms. Dysphagia was confirmed in 34 out of 35 symptomatic patients that accepted to undergo FEES. Patients with OSA exhibited lower bolus location at swallow onset, greater pharyngeal residue, and higher frequency and severity of penetration and aspiration events than healthy subjects (p < 0.05).ConclusionA consistent number of patients with OSA show symptoms of dysphagia, which are increased in females and patients with a greater OSA symptomatology, anxiety and depression, and gastroesophageal reflux. The EAT-10 appears a useful tool to guide the selection of patients at high risk of dysphagia. In clinical practice, the integration of screening for dysphagia in patients with OSA appears advisable.
