Sleep Extension Improves Neurocognitive Functions in Chronically Sleep-Deprived Obese Individuals
Background: Sleep deprivation and obesity, are associated with neurocognitive impairments. Effects of sleep deprivation and obesity on cognition are unknown, and the cognitive long-term effects of improvement of sleep have not been prospectively assessed in short sleeping, obese individuals. Objective: To characterize neurocognitive functions and assess its reversibility. Design: Prospective cohort study. Setting: Tertiary Referral Research Clinical Center. Patients: A cohort of 121 short-slee...

A change in objective sleep duration is associated with a change in the serum adiponectin level of women with overweight or obesity undergoing weight loss intervention
Background Although the serum adiponectin level is inversely correlated to body mass index and closely associated with obesity and related diseases, neither the impact of weight loss on the adiponectin level nor other factors that might influence the adiponectin level during weight loss intervention are well documented. Objective The objective of the study is to assess the change in the serum adiponectin level during weight ...

Obesity, Cardiovascular Disease and Sleep Disorders: Insights into the Rising Epidemic
Cardiovascular disease (CVD) is the main cause of death among adult men and women in the USA and impacts millions around the globe. Traditional risk factors for CVD include obesity, diabetes, hypertension and dyslipidemia. The modern-day epidemic of obesity not only increased the rate of CVD but also ushered in an additional CVD risk factor to be added to the list; that is obstructive sleep apnea (OSA). In this review, we discuss the growing epidemic of obesity and OSA, highlighting the common pathogenic ...

Sleep Restriction Enhances the Daily Rhythm of Circulating Levels of Endocannabinoid 2-Arachidonoylglycerol
Study Objectives: Increasing evidence from laboratory and epidemiologic studies indicates that insufficient sleep may be a risk factor for obesity. Sleep curtailment results in stimulation of hunger and food intake that exceeds the energy cost of extended wakefulness, suggesting the involvement of reward mechanisms. The current study tested the hypothesis that sleep restriction is associated with activation of the endocannabinoid (eCB) system, a key component of hedonic pathways ...

Sleep Deficiency is a Modifiable Risk Factor for Obesity and Cognitive Impairment and Associated with Elevated Visfatin
AIM: To study the interaction between sleep deprivation, obesity and cognitive functions, and the effect of following a balanced low caloric diet and increasing sleep duration on those variables. SUBJECTS AND METHODS: Ninety two obese females with mean age 47.00 ± 2.00 years and body mass index (BMI) 36.14 ± 3.00 kg/m² were divided into 3 groups according to their sleeping hours. They followed balanced low-caloric diet and were instructed to increase sleeping hours. Full ...

Gut microbiota and glucometabolic alterations in response to recurrent partial sleep deprivation in normal-weight young individuals
Objective: Changes to the microbial community in the human gut have been proposed to promote metabolic disturbances that also occur after short periods of sleep loss (including insulin resistance). However, whether sleep loss affects the gut microbiota remains unknown. Methods: In a randomized within-subject crossover study utilizing a standardized in-lab protocol (with fixed meal times and exercise schedules), we studied nine normal-weight men at two occasions: ...

Obese Veterans Enrolled in a Veterans Affairs Medical Center Outpatient Weight Loss Clinic Are Likely to Experience Disordered Sleep and Posttraumatic Stress
Study Objectives: This cross-sectional study aimed to characterize sleep patterns, the quality and duration of sleep, and estimate the prevalence of common sleep disorders and posttraumatic stress disorder (PTSD) in a hospital-based Veterans Affairs MOVE! (Managing Overweight Veterans Everywhere) clinic. Methods: Participants completed five instruments: the Pittsburgh Sleep Quality Index (PSQI), Smith’s Measure of Morningness/Evenin...
