In a nutshell
This article investigated the link between sleep disturbance, body mass index (BMI) and blood pressure (BP) with blood glucose control in prediabetes and newly diagnosed, untreated diabetes. The authors concluded that sleep disturbance is associated with higher BMI, BP and worse blood glucose control in these patients.
Some background
Prediabetes is a condition where blood glucose is higher than normal but not as high as in T2D. It can be reversed with lifestyle changes such as diet and exercise. Sleep disturbance has been linked to bad glucose control in type 2 diabetes (T2D). However, its association with glucose control has not been explored in patients with prediabetes. Also, the association between sleep disturbance and body weight in these patients remains under investigation.
Methods & findings
The study involved 962 overweight and obese patients with prediabetes or untreated newly diagnosed T2D. BMI, BP, and blood glucose were measured. Patients were given questionnaires about their sleep patterns.
54% of all patients reported poor sleep quality, with an average sleep duration of 6.6 hours. In patients that got less than 5 hours or more than 8 hours of sleep had higher fasting glucose. Patients that reported fewer than 6 hours sleep and shift work had higher BMI’s.
Social jet lag (not getting enough sunlight causing the body to be confused about when you should be asleep) and delayed chronotype (getting up late in the morning and going to bed late at night) were associated with higher BP levels.
The bottom line
The authors concluded that too much or too little sleep was associated with worse blood glucose control, higher BMI and BP levels.
The fine print
This study was based on patient self-reported data. Data collected in this way is not always reliable.
