Is long sleep duration a new risk factor for obesity?

Abstract

Sleep is an important modulator for neuroendocrine functions and glucose metabolism. However the data about the relation between long sleep duration and obesity is scarce and unclear, so herein we evaluated both long and short sleep durations either with high or poor quality: within different age and obesity groups to define the interaction between obesity and sleep. Here in our group most of the patients (79.6%) sleeping longer than 8 hours-long sleepers- were either obese (49%) or morbid obese (30.6%) and long sleep duration was significantly common compared to control group (79.5% vs. 6%; and P < 0.001). We can conclude that as well as short sleep duration; long sleep duration has to be taken into concern as a cause or result of obesity.
