Night owls 'more likely to develop diabetes'

People who stay up late at night are more likely to develop diabetes than early risers, a new study has found.
Researchers said the risk of diabetes is greater for night owls, as the combination of sleep loss, poor sleep quality and eating at inappropriate times might lead to metabolic change.
Scientists quizzed 1,620 participants between the ages of 47 and 59 about their sleep-wake cycle, sleep quality and lifestyle habits, such as daily exercise levels. They also took blood samples to test metabolic health and body fat.
Based on the results, 480 were classed as morning chronotypes and 95 as evening chronotypes, meaning either they got up particularly early or went to bed very late. The remaining participants had a sleep-wake cycle between those two extremes.
The study - which was published in the 'Journal of Clinical Endocrinology & Metabolism' - found that even though evening chronotypes tended to be younger, they had higher levels of body fat or fat in the blood.
Night owls were 73pc more likely to develop diabetes. There are 200,000 people in Ireland with diabetes but half are unaware of their condition.
