Evaluation of Sex Differences in Glucose Metabolism in Response to Sleep Curtailment
Brigham and Women's Hospital
Summary
The goal of this study is to learn whether insufficient sleep affects glucose metabolism differently in healthy men and women.
Description
Two-thirds of Americans report regularly obtaining an insufficient amount of sleep. Chronic sleep deficiency is associated with negative health consequences such as obesity, cardiovascular disease, diabetes, and metabolic syndrome. Laboratory studies have shown that sleep restriction reduces glucose tolerance in otherwise healthy adults, and it is now well established that sleep restriction decreases insulin sensitivity. However, there is a significant gap in the literature regarding how sex differences may drive disparate metabolic outcomes in men and women in response to sleep loss. Epidemi…
