This study sought to examine predictors of subjective/objective sleep discrepancy in poor sleepers. Forty-two individuals with insomnia symptoms (mean age = 36.2 years, 81% female) were recruited to take part in a prospective study which combined seven days of actigraphy with daily assessment of sleep perceptions, self-reported arousal, sleep effort, and mood upon awakening. A high level of int...

OBJECTIVE Nocturnal awakenings are one of the most prevalent sleep disturbances in the general population. However, little is know about how its severity affects co-morbidity with mental disorders and organic diseases. METHODS A representative sample consisting of 8937 non-institutionalized individuals aged 18 or over living in Texas, New York and California states were interviewed by telepho...

OBJECTIVE Gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA) often coexist. We sought to determine the presence and direction of any association between GERD and sleep events in patients with OSA. MATERIALS AND METHODS We conducted a case-crossover study among 18 patients with known OSA and GERD. All study patients underwent overnight simultaneous polysomnography and eso...

Materials and methods Eighteen non-obese adults with T1D (8 males, age=26.3±5.1), without chronic complications were studied. The following instruments were used during ten consecutive days: sleep diaries (with Visual Analogue Scales for rating sleep quality), actimeters, and a home fingertip glucometer (6.41±1.5 tests a day). The analysis was made using fitted inflated beta regression models w...

were used to compare differences between and within groups. Results: In our study, adolescents with CFS stayed in bed longer and had a significantly delayed mid sleep time during work days compared to the healthy controls. Further, adolescents with CFS also scored significantly worse on insomnia (mean 3.4 vs 4.9), sleepiness (mean 3.7 vs 5.0) and awakening problems (mean 2.5 vs 4.9) on KSQ. Mor...

The cortisol awakening response (CAR) is a distinct facet of the circadian cortisol rhythm associated with various health conditions and risk factors. It has repeatedly been suggested that the CAR could be a result of the anticipated demands of the upcoming day (stress anticipation) and could support coping with daily life stress. In a sample of 23 healthy participants CARs were assessed on two...

UNLABELLED BACKGROUND/STUDY CONTEXT: The cortisol diurnal rhythm has previously been examined in relation to age and health behaviors. However, less is known about the relationship between multiple health behaviors and diurnal cortisol in the context of aging, where it is possible that the impact of health behaviors on cortisol varies as a function of age. This study compared the awakening resp...

Few studies have examined napping in irregular work schedules such as those experienced by freight locomotive engineers. The current study examined the effect of napping in irregular work schedules on sleep length and three subjective measures: ability to go to sleep, ability to stay asleep, and a feeling of being well-rested upon awakening. One hundred and seventy-nine freight engineers comple...
