Change in Sleep Duration and Type 2 Diabetes: The Whitehall II Study.

ABSTRACT:

Objective

Evidence suggests that short and long sleep durations are associated with a higher risk of type 2 diabetes. Using successive data waves spanning >20 years, we examined whether a change in sleep duration is associated with incident diabetes.

Research design and methods

Sleep duration was reported at the beginning and end of four 5-year cycles: 1985-1988 to 1991-1994 (n = 5,613), 1991-1994 to 1997-1999 (n = 4,193), 1997-1999 to 2002-2004 (n = 3,840), and 2002-2004 to 2007-2009 (n = 4,195). At each cycle, change in sleep duration was calculated for participants without diabetes. Incident diabetes at the end of the subsequent 5-year period was defined using 1) fasting glucose, 2) 75-g oral glucose tolerance test, and 3) glycated hemoglobin, in conjunction with diabetes
