SIB# 418- Sleep, Obesity and Diabetes

The Study: Metabolic effects of sleep disruption, links to obesity and diabetes 

The Facts:

a. The study looked at the effect of sleep disruption on metabolic factors.

b. Previous studies have shown that decreasing sleep time and quality of sleep can affect both insulin sensitivity and glucose tolerance. 

c. This paper is a review of the relevant literature.

d. The authors noted that that 22% of people got less than 6 hours of sleep on work days

e. “Additionally, in persons sleeping less than 8 hours, increased BMI was proportional to decreased sleep.”

f. The authors also noted a link between shortened sleep and obesity in a 16 year study.

g. They conclude, “Despite the convincing evidence for the deleterious effects of decreased sleep quality and quantity, there is a paucity of research performed to test sleep extension or sleep improvement as a therapeutic approach to improve metabolic health in individuals who have acquired or are at risk for developing obesity, diabetes, or cardiovascular disease. ”

 Take Home:

Decreased time and quality sleep both may affect health, particularly in the area of glucose regulation.

Reviewer's Comments:

I think this is something most of us know but don’t think about enough. It’s more important than just feeling a little tired because you didn’t get enough sleep. It can affect you in serious ways. This article is a brief read and I think you will find it interesting.
