ABSTRACT
The objective of this cross-sectional analysis was to investigate in 109 adults with type 1 diabetes the relationship between sleep, circadian parameters and insulin sensitivity, as assessed by estimated glucose disposal rate (eGDR). In multiple regression analysis only poor sleep quality and sleep duration were negatively associated with eGDR (β = −0.219 [95%CI:-1.977; −0.445], p = .002 for poor sleep quality; β = −0.183 [95%CI: −0.645; −0.111], p = .006 for sleep duration) independent of age, gender, smoking status and body mass index. In conclusion, poor sleep quality and longer sleep duration were significant predictors of decreased insulin sensitivity. Social jetlag, chronotype, and sleep debt had no effect on insulin sensitivity.
