OBJECTIVE To evaluate feasibility, efficacy, and tolerability of Sudarshan Kriya yoga (SKY) as an adjunctive intervention in patients with major depressive disorder (MDD) with inadequate response to antidepressant treatment. METHODS Patients with MDD (defined by DSM-IV-TR) who were depressed despite ≥ 8 weeks of antidepressant treatment were randomized to(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)
PURPOSE Excessive daytime sleepiness (EDS) in older adults is associated with obstructive sleep apnea, falls, reduced quality of life, and mortality. The Epworth Sleepiness Scale (ESS) is widely used to assess sleepiness. However, EDS assessment with the ESS may not be accurate in older adults. We aimed to (1) describe the responsiveness of nondemented(More)
BACKGROUND The prevalence of sleep-related breathing disorder (SRBD) and insomnia symptoms increases considerably with advancing age, but little is known about their cooccurrence and their effects on daytime functioning when present together. METHODS Older adults with (cases, n = 99) and without (controls, n = 100) symptoms of insomnia underwent 2 nights(More)
Older adults have high prevalence rates of insomnia symptoms, yet it is unclear if these insomnia symptoms are associated with objective impairments in sleep. We hypothesized that insomnia complaints in older adults would be associated with objective differences in sleep compared with those without insomnia complaints. To test this hypothesis, we conducted(More)
OBJECTIVES This study examined the effects of high-intensity resistance strength training and walking (E), individualized social activity (SA), and resistance training and walking combined with social activity (ESA) on everyday function in long-term care (LTC) residents and explored the relationship between change in everyday function and change in sleep.(More)
This study examined whether individuals with primary insomnia (PI) are more reactive to stress than good sleepers (GS). PI and GS (n = 20 per group), matched on gender and age, completed three nights of polysomnography. On the stress night, participants received a mild electric shock and were told they could receive additional shocks during the night.(More)
There are no established questionnaires that evaluate habitual sleep practices in the context of beliefs and attitudes about sleep. This study describes an effort to develop and evaluate a questionnaire that assesses habitual sleep; behaviors associated with sleep and potential sleep problems; sleep hygiene; social and environmental determinants of sleep;(More)
Explore how social factors influence sleep, especially sleep-related beliefs and behaviors. Sleep complaints, sleep hygiene behaviors, and beliefs about sleep were studied in 65 black/African American and white/European American women. Differences were found for snoring and discrepancy between sleep duration and need. Sleep behaviors differed across groups(More)
SLEEP COMPARED TO WAKEFULNESS. In obstructive sleep-disordered breathing, the airway completely (apnea) or partially (hypopnea) occludes despite continued respiratory effort. Arousals from sleep temporarily restore upper airway patency, only to be followed by a repetitive cycle of airway collapse and arousal. This phenomenon produces sleep fragmentation and(More)
