REVIEW
Francesco P Cappuccio, Michelle A Miller
PURPOSE OF REVIEW: This review summarises and discusses the epidemiological evidence suggesting a causal relationship between sleep duration and cardio-metabolic risk and outcomes in population. RECENT FINDINGS: Sleep duration is affected by a variety of cultural, social, psychological, behavioural, pathophysiological and environmental influences. Changes in modern society-like longer working hours, more shift-work, 24/7 availability of commodities and 24-h global connectivity-have been associated with a gradual reduction in sleep duration and sleeping patterns across westernised populations...

This study aimed to evaluate the associations of nighttime sleep duration and midday napping with risk of depressive symptoms incidence and persistence among middle-aged and older Chinese. Data from China Health and Retirement Longitudinal Study, CHARLS (2011-2013), were analyzed. Depressive symptoms were identified by the 10-item version of the Centre for Epidemiological Studies Depression scale (CESD-10). Multivariate binary logistic regression models were fitted. There were 7156 individuals with CESD-10 scores < 10 and 3896 individuals with CESD-10 scores ≥ 10 at baseline included in this study...

Racial/ethnic minorities experience a disproportionate risk of both suboptimal sleep and obesity, and the relationship between sleep and obesity may differ by race/ethnicity for modifiable and non-modifiable reasons. Because many people of color have historically lived and continue to largely live in disadvantaged, obesogenic physical and social environments, these greater adverse exposures likely negatively affect sleep, resulting in physiological dysregulation. Physiological dysregulation may, in turn, lead to increased obesity risk and subsequent health consequences, which are likely more influential than potential genetic differences in race, a social construct...

REVIEW
Rachel P Ogilvie, Sanjay R Patel
Sleep is a state of consciousness that is preserved across animal species whose exact function is not yet clear but which has a vital impact on health and well-being. Epidemiological evidence suggests sleep duration in both children and adults has been decreasing over the past half-century, while at the same time rates of overweight and obesity have been increasing. Short sleep duration along with other dimensions of poor sleep has been associated with obesity both cross-sectionally and longitudinally. These data suggest a potential causal relationship between poor sleep and greater rates of weight gain that may be related to effects of sleep on dietary intake or physical activity...

The acute and chronic effects of traumatic brain injury (TBI) have been widely described; however, there is limited knowledge on how a TBI sustained during early or mid adulthood will influence aging. Epidemiological studies have explored whether TBI poses a risk for dementia and other neurodegenerative diseases associated with aging. We will discuss the influence of TBI and resulting medical comorbidities such as endocrine, sleep and inflammatory disturbances on age-related grey and white matter changes and cognitive decline...

Acromegaly is a rare disease with nonspecific symptoms with acral enlargement being almost universally present at diagnosis. The estimated prevalence is 40-125 cases/million but targeted universal screening studies have found a higher prevalence (about 10 fold). The aim of the ACROSAHS study was to investigate the prevalence of acromegaly and acromegaly comorbidities in patients with sleep apnea symptoms and acral enlargement. ACROSAHS was a Spanish prospective non-interventional epidemiological study in 13 Hospital sleep referral units...

Obstructive sleep apnea (OSA) is a complex disease in which humans face episodes of intermittent hypoxia and it affects men and women. Patients with OSA present hypertension and sympathetic overactivity among several other dysfunctions. Therefore, one important question remains: are the autonomic dysfunctions associated with OSA similar in male and female? This is an unresolved question since sex factors are overlooked in most clinical and experimental studies. Epidemiological data indicate that sex exerts an important influence in the prevalence of OSA and associated comorbidities, such as hypertension...

Parasomnia is a common pediatric sleep disorder that can cause parents or caregivers distress when experienced by their children. Based on the International Classification of Sleep Disorders, parasomnias can be divided into two subgroups: non-rapid eye movement (NREM) parasomnias and rapid eye movement (REM) parasomnias. REM sleep parasomnias include nightmares, REM behavior disorder, and sleep paralysis, whereas NREM sleep parasomnias include disorders of arousal such as confusional arousals, sleepwalking, sleep talking, night terrors, and sleep-related eating disorder...

STUDY OBJECTIVES: Erythrocyte levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Omega-3 Index) were previously found to be associated with obstructive sleep apnea (OSA) at very low levels (< 5.0%) in only one epidemiologic study. OSA has comorbidities, such as arterial hypertension, heart failure, or major depression, also associated with a low Omega-3 Index. These comorbidities can be improved by increasing intake of EPA and DHA, and thus the Omega-3 Index, preferably to its target range of 8% to 11%...

The Obstructive Sleep Apnea Syndrome (OSAS) is a breathing disorder characterized by repeated episodes of apnea/hypopnea occurring during sleep and caused by the obstruction of the upper airway. As OSAS can have a significant impact on quality of life, an early diagnosis and a multi-specialized recognition become important. Therapeutic proposals include the Mandibular Advancement Devices (MADs), intraoral devices that induce a mandibular advancement during the night to eliminate snoring and apnea. Italian guidelines on dental aspects of OSAS in adults and children focus primarily on anamnestic and clinical methods by which the dentist, in a role of epidemiological sentinel, can first identify a patient with OSAS and then participate in the therapeutic process using specific orthodontic intraoral devices...

Restless legs syndrome (RLS) and periodic limb movement disorder (PLMD) are under-recognized sleep disorders in children and adolescents. Several recent epidemiological studies have shown that RLS and PLMD are common in the pediatric population, and if left untreated, may lead to cardiovascular and neurocognitive consequences. Therefore, early diagnosis and intervention may help preventing long-term consequences. The management of RLS and PLMD in children involves both non-pharmacologic and pharmacologic approaches...

While public awareness of sleep related disorders is growing, sleep apnea syndrome (SAS) remains a public health and economic challenge. Over the last two decades, extensive controlled epidemiologic research has clarified the incidence, risk factors including the obesity epidemic, and global prevalence of obstructive sleep apnea (OSA), as well as establishing a growing body of literature linking OSA with cardiovascular morbidity, mortality, metabolic dysregulation, and neurocognitive impairment. The US Institute of Medicine Committee on Sleep Medicine estimates that 50-70 million US adults have sleep or wakefulness disorders...
