Women who develop gestational diabetes while pregnant are at higher risk of going on to develop type 2 diabetes, and international researchers say poor sleep could be exacerbating this risk. The team followed a group of 2891 women with a history of gestational diabetes for an average of 17 years, with one in five women developing type 2 diabetes during the study. Looking at self-reported data on their sleep habits when they were first recruited, the researchers say women who slept six or fewer hours a day and snored regularly were the most likely to develop type 2 diabetes. Both snoring and shorter daily sleep were also independently linked to type 2 diabetes risk, the researchers say. They say improving sleep health could be key to reducing the rate of type 2 diabetes among this risk group.
