Several studies of sleep-breathing physiology have suggested that sleep deprivation may worsen obstructive sleep apnea. The aim of the study was to determine the direct effect of night work on breathing variables during sleep in fast-rotating shift workers. Twenty one men - police officers, fast-rotating shift workers, underwent polysomnography on 2 occasions: under a normal sleeping condition ...

BACKGROUND Prior studies have shown that sleep disturbances are related to falling and its risk factors, such as poorer cognition, depression, and physical function. However, little is know about the gender-specific associations between falling and sleep duration. METHODS Study participants were from the annual Health Examination for the Elderly Program in the National Taiwan University Hospi...

INTRODUCTION Long-haul truck drivers in the United States suffer disproportionately high injury rates. Sleep is a critical factor in these outcomes, contributing to fatigue and degrading multiple aspects of safety-relevant performance. Both sleep duration and sleep quality are often compromised among truck drivers; however, much of the efforts to combat fatigue focus on sleep duration rather th...

OBJECTIVE The goal was to explore the effects of duration and regularity of sleep schedules on BMI and the impact on metabolic regulation in children. METHODS Sleep patterns of 308 community-recruited children 4 to 10 years of age were assessed with wrist actigraphs for 1 week in a cross-sectional study, along with BMI assessment. Fasting morning plasma levels of glucose, insulin, lipids, and...

STUDY OBJECTIVES To determine whether the duration of sleep, sleep quality, insomnia, or sleep disturbance was associated with incident breast cancer in the Women's Health Initiative (WHI). DESIGN Prospective cohort study. SETTING Women enrolled in one of the Clinical Trial (CT) arms or the Observational Study (OS) from the WHI conducted in the United States. PARTICIPANTS This study inclu...

PURPOSE To review the association between sleep duration and self-rated health. METHODS A search for original and review articles focusing on sleep duration and self-rated health was performed in PubMed. The general search strategy was [("sleep duration" OR "total sleep time" OR "time in bed") AND "self-rated health"]. RESULTS We found 22 articles in the English language; 8 articles with no...

The aim of the present study was to investigate the sleep promoting effect of BR-16A, a polyherbal formulation along with GABAergic drugs. Pentobarbitone-induced hypnosis test was used as an animal model to explore its role in sleep. Pentobarbitone produces quick the sleep latency (onset) and prolongation of total sleep time (duration). Seep latency and total sleep time were used as parameters ...

To the Editor: I have recently read with interest the article by FernandezMendoza et al concerning the predictive ability of insomnia with objective short sleep duration for the incidence of hypertension. They also described that poor sleepers who slept ≥6 hours showed a reduced risk for incident hypertension. Although they mentioned that the findings were consistent with their past findings by...

Epidemiologic studies have shown that sleep duration is associated with overall mortality. We conducted a systematic review of the associations between sleep duration and all-cause and cause-specific mortality. PubMed was systematically searched up to January, 2008 to identify studies examining the association between sleep duration and mortality (both all-cause and cause-specific) among adults...
