A recent meta-analysis explored the connection between sleep and the risk of type 2 diabetes, as indicated on a Diabetes in Control report.

Researchers have attempted to determine how many hours of sleep are associated with the lowest risk of type 2 diabetes. The study was a meta-analysis and was performed to assess the relationship between sleep duration and the risk of type 2 diabetes.

The study was designed by conducting a literature search (up to 20 March 2014) of PubMed (Medline) and Embase for prospective studies which examined the association between sleep duration and risk of type 2 diabetes. Studies were included in this meta-analysis if they satisfied the following criteria: the study design was prospective, the exposure of interest was sleep duration, the outcome was type 2 diabetes, and the investigators reported relative risks (RRs) with 95% CIs for at least three quantitative categories of short sleep or long sleep duration.
