Sleep Quality Linked To Diabetes

Posted on Wed, Sep 21, 2011

Research by Philadelphia's Children's Hospital has found a clear link between sleep quality and blood sugar levels, according to a study published recently in the Journal of Diabetes Care. 

The researchers studied 62 obese adolescents with a mean age of 14 years.  Over a period of one and a half days, the children underwent glucose testing and an overnight sleep study. In addition to measuring total sleep time, the scientists studied "sleep architecture," analysing the different stages of sleep such as slow-wave 'deep' sleep and rapid eye movement ('REM' or dream) sleep.

The study found obese teenagers who don't get the proper amount of sleep may have disruptions in insulin secretion and blood sugar (glucose) levels. In particular, a lower duration of "deep" sleep correlated with decreased insulin secretion.  The study suggests that getting a good night's sleep may help to stave off the development of type 2 diabetes in these adolescents.

Diabetes Epidemic Is 'Over Rated'

Posted on Mon, Feb 28, 2011

We are constantly being told about the ‘diabetes epidemic’ and how diabetes is the single most serious health problem for the developed world.  As a result, huge public and private investments are being made in prevention, treatment and hopefully cure.

But here’s a question:  How come the same investments aren’t being made in dealing with sleep disordered breathing? 

After all, diabetes affects only around 2.8% of the population … whereas sleep apnoea is estimated to affect almost 8% of the population, and around 30% of the adult population have some form of serious sleep disordered breathing condition.  Given that sleep disordered breathing is a proven CAUSE of type 2 diabetes, you’d think SDB would get serious attention as a possible part of the solution.

At the very least, treatment of sleep disordered breathing can help in the treatment of type 2 diabetes, so it should at least get equal attention.

It could even be argued that SDB should get more attention than diabetes because of the clear links between SDB and other serious consequences and co-morbidities, including hypertension, gastro oesophageal reflux disease (GERD), cardiovascular disease, depression, obesity, loss of libido and impotence.  Factor in the further issues of quality of life and safety and SDB truly is a major health issue. 

What do YOU think?
