Summary

Insufficient and disrupted sleep has become increasingly prevalent worldwide, in parallel with an epidemic of obesity, and cardiovascular and metabolic disease. Causes of sleep inadequacy include voluntary short sleep, light-induced sleep disruption, and sleep disorders such as insomnia, sleep apnea, and narcolepsy. How short sleep and poor-quality sleep are associated with obesity risk and cardiometabolic disease is not fully understood. While the sleep disruption-cardiometabolic risk relationship has been evident from observational studies, experimental and real-world interventional studies shed new light on why this happens and what to do about it. This symposium, chaired by Drs Poyares and Skuladottir, will cover the underlying pathophysiological mechanisms between sleep loss and cardiometabolic risk in various populations. Sleep in pregnancy, an often-overlooked area with significant potential for impactful interventions, will also be discussed. Importantly, potential preventive and therapeutic strategies for improving sleep-cardiometabolic health will be discussed, covering recent, high impact findings on sleep extension intervention and its implications for weight loss. Speakers represent a broad range from early to senior investigators from five countries and three different continents. Specifically, Dr. Pamidi will discuss the implications of sleep disordered breathing for cardiometabolic risk in pregnant individuals. Dr. Covassin will present mechanistic evidence linking insufficient sleep to vascular injury. Cardiovascular and metabolic complications of narcolepsy will be reviewed by Dr. Somers. Dr. Dogg will address the impact of light exposure on sleep and cardiometabolic risk and Dr. Tasali will discuss the role of healthy sleep for weight management. Gaps in the literature and future directions will also be identified and discussed by the panel.
