Role of Sleep Duration and Quality in the Risk and Severity of Type 2 Diabetes Mellitus
Abstract by Brienne Davis
This study sought to examine self-reported sleep duration and quality, and glycemic control in African Americans with type 2 diabetes. A total of 298 participants completed the study, which consisted of 30-45 minute interviews and medical chart reviews. This research is unique because it takes into consideration "perceived sleep debt", a measure of habitual sleep time and subjective sleep need. Results revealed that a higher perceived sleep debt or lower sleep quality are associated with poorer glucose control after controlling for age, sex, body mass index (BMI), insulin use and presence of major complications. The researchers suggest that in a modern society in which sleep deprivation is increasingly common, one must consider the impact this behavior may be having on the current epidemic of type 2 diabetes.
