Babak Mokhlesi, M.D., from the University of Chicago, and colleagues assessed the effect of sleep disturbances and circadian misalignment on adults with prediabetes.
The analysis included 962 overweight/obese adults (55 per cent male; mean age, 52.2 years) with prediabetes or recently diagnosed, untreated type 2 diabetes who completed a two-hour oral glucose tolerance test and validated sleep questionnaires.
The researchers found that mean sleep duration was 6.6 hours. More than half of participants reported poor sleep quality (54 per cent) and high risk for obstructive sleep apnoea (64 per cent).
Among those reporting less than five hours or more than eight hours of sleep per night, haemoglobin A1c was significantly higher. There was also an association between sleep duration of more than eight hours and higher fasting glucose and between sleep duration of less than six hours and higher body mass index.
