OBJECTIVES Lower socioeconomic status is associated with short or long sleep duration and sleep disturbance (e.g., sleep apnea), which are all related to increased mortality risk. General sleep complaints, however, which may better approximate symptoms as they are experienced, have not been examined in a large population sample. METHODS Sample consisted(More)
Continuous positive airway pressure (CPAP) is a highly efficacious treatment for obstructive sleep apnea (OSA) but adherence to the treatment limits its overall effectiveness across all age groups of patients. Factors that influence adherence to CPAP include disease and patient characteristics, treatment titration procedures, technological device factors(More)
BACKGROUND Little is known about the social determinants of sleep attainment. This study examines the relationship of race/ethnicity, socio-economic status (SES) and other factors upon sleep quality. METHODS A cross-sectional survey of 9,714 randomly selected subjects was used to explore sleep quality obtained by self-report, in relation to socioeconomic(More)

DESIGN Cross-sectional analysis of data from the 2006 Behavioral Risk Factor Surveillance System (BRFSS). SETTING Epidemiologic. PARTICIPANTS Complete-case analysis included 155,877 participants who(More)
PURPOSE To help practitioners avoid adverse perioperative events in patients with obstructive sleep-disordered breathing. REVIEWERS Members of the American Academy of Sleep Medicine's Clinical Practice Review Committee. METHODS A search of MEDLINE database using MeSH terms apnea, obstructive sleep apnea and anesthesia was conducted in October 2001. This(More)
STUDY OBJECTIVES Excessive daytime sleepiness (EDS) is associated with increased mortality in older adults, yet sleep disordered breathing (SDB), a common cause of sleepiness, has not been shown to increase mortality in older adults. This study examined the relationship between daytime sleepiness, SDB, self-report sleep parameters, and mortality in older(More)
Perceived discrimination is a potential cause of racial and ethnic disparities in health. Disturbed sleep may serve as a mechanism linking perceived racism with health consequences. This study investigates data from 7,148 adults from Michigan and Wisconsin who participated in the 2006 Behavioral Risk Factor Surveillance System. Hierarchical logistic(More)
Melatonin is increasingly used for the treatment of sleep disorders. Surge-sustained formulations consisting of combined immediate release and controlled release dosing may mimic the endogenous melatonin physiologic profile. However, relatively little is known about the pharmacokinetic properties of low-dose (<0.5mg) and high-dose (>2mg) melatonin in a(More)
OBJECTIVES To compare the effects of physical resistance strength training and walking (E), individualized social activity (SA), and E and SA (ESA) with a usual care control group on total nocturnal sleep time in nursing home and assisted living residents. DESIGN Pretest-posttest experimental design with assignment to one of four groups for 7 weeks: E(More)
