Obstructive sleep apnea (OSA), a disorder characterized by repetitive collapse of the upper respiratory tract during sleep, occurs in about 4% of middle-aged men and 2% of women. The incidence of the disorder is rising due to an increase in obesity and ageing of the population. Patients with obstructive sleep apnea are at elevated risk of some endocrinal and metabolic disorders, which may lead to serious consequences including shortening of life expectancy. The recognition and understanding of interactions between local upper airway dysfunction and its endocrinal consequences is therefore vital...

If obesity were tied only to too much food or too little physical activity, the cure would be a simple matter of counting calories or keeping track of steps with a pedometer. Unfortunately, obesity is much more complex. Many other factors come into play, including so-called hunger genes that make a person more susceptible to obesity, infection with certain pathogens linked to weight gain, hormones that dampen or stimulate appetite, sleep disruption that can trigger overeating, and social networks that can promote obesity...

BACKGROUND: Although many studies have evaluated the relationships between sleep duration and cardiovascular (CV) events/risk factors, longitudinal associations with time-dependent sleep duration have not been adequately assessed. METHODS: A retrospective, longitudinal study was conducted involving individuals aged 20 years or older that received annual health check-ups at St. Luke's International Hospital from 2005 to 2010. Data collection included self-reported demographic, clinical and health habit information (including sleep duration; 6 <, 6-7, 7-8, 8 ≤), baseline examinations, and laboratory measures for each year...

OBJECTIVE: To investigate associations between a health behavior score and prevalence of hypertension and overweight/obesity. METHODS: Adults (n = 4,609; 19-85 years) were included from the cross-sectional Australian National Nutrition and Physical Activity Survey. A health behavior score was derived based on individuals meeting recommendations for diet quality, smoking, physical activity, sedentary time, and sleep. Poisson regression estimated the prevalence ratio (PR) of hypertension and overweight/obesity by health behavior score...

The obesity rate is higher among veterans than the general population, yet few studies have examined their eating behaviors, and none have examined the presence of night eating and related comorbidities. This study examines night eating syndrome (NES) among veterans seeking weight management treatment, and relationships between NES and weight, insomnia, disordered eating, and psychological variables. The sample consisted of 110 veterans referred to a weight management program at VA Connecticut Healthcare System...

Shiftworkers are exposed to several adverse health conditions, one being eating at night. Food consumption at an unnatural time-of-day is thought to be one of the main factors responsible for the increased risk of developing metabolic diseases, such as obesity and diabetes mellitus. The underlying mechanism is considered to include disruption of the circadian organization of physiology, leading to disruption of metabolism. When food is consumed at night, the hypothalamus, a brain region central to homeostasis, receives contradicting input from the central clock and the systemic circulation...

Short sleep duration in childhood has been associated with increased risk for overweight and obesity. Research suggests that physical activity might mediate this association. However, studies examining associations between physical activity and sleep in young children have reported equivocal findings. A possible explanation for these inconsistencies is that past studies have looked at total physical activity rather than examining physical activity regularity. We aimed to explore the associations between physical and sedentary activity regularity (ie, consistent vs intermittent behavior) and sleep in preschoolers and kindergartners...

OBJECTIVES: Aging, female sex, and urbanization increase the risk of sleep impairment. Sleep in urban-dwelling elderly African women has been sparsely studied. We studied the characteristics and correlates of sleep quality and habitual sleep duration in a primary care population of urban-living Nigerian women. METHODS: Sleep quality and sleep duration over the previous 1 month were estimated using the Pittsburgh Sleep Quality Index (PSQI). Excessive daytime sleepiness, risk of obstructive sleep apnea (OSA), and depressive symptoms were also assessed...

PURPOSE OF REVIEW: With the prevalence of obesity rapidly growing, bariatric anaesthesia becomes everyday anaesthesia rather than a subspecialty. In this review, we are aiming to draw attention to this complex group of patients and their comorbidities, relevant to everyday practice for contemporary anaesthetists. RECENT FINDINGS: We wanted to focus greatly on sleep-related breathing disorders, because preoperative screening, diagnosis and treatment of the aforementioned make a huge impact in the improvement of preoperative morbidity and mortality, including positive effects on the cardiovascular system...

BACKGROUND: With increasing use of atypical antipsychotic (AAP) agents, the concern has been raised about the association between AAP agents and medical complications. Obstructive sleep apnea (OSA) is a common breathing disorder that adversely affects health and quality of life. Because the major risk factors for OSA are weight gain and obesity by altering the upper airway anatomy, an association between AAP and development of OSA is predictable. However, we hypothesized that AAP may promote OSA not only by weight gain but also because of its potential effects on upper airway muscle function...

Although non-invasive ventilation (NIV) has been used since the 1960's in the polio epidemic, the development of modern bilevel PAP devices did not become a reality until the 1990's. Over the last 25 years bilevel PAP technology options have exponentially increased. The number of patients receiving this treatment both in the acute setting as well as at home is steadily growing. However, a knowledge gap exists in the way these device settings are adjusted to achieve synchrony and match patient's unique respiratory failure physiology...
