Being a night owl in diabetes increases risk of depression

Bangkok, April 3: If a person is diabetic and prefer to sleep late, may be at an increased risk of developing depression, researchers say.
According to a study, people with Type 2 diabetes who are “night owls” and prefer the evening for activity report having more symptoms of depression than those who rise as well as sleep early.

“These findings are important because depression is common in patients with Type 2 diabetes,” said lead investigator Sirimon Reutrakul, Associate Professor at Mahidol University in Bangkok, Thailand.

The study was done on Type 2 diabetes patients, supports a link between circadian regulation and psychological functioning. 

“Learning more about the relationship between depression and circadian functioning might help us figure out strategies to improve physical and mental health for patients with diabetes,” Reutrakul said.

The team examined people with type 2 diabetes for the study, presented at the Endocrine Society’s 99th annual meeting in Orlando.
The study was done on diabetic patients of two different geographic regions: Chicago and Thailand. The US group consisted of 194 patients, 70 per cent of whom were women, while the Thai group consisted of 282 patients, 67 per cent of whom were women.


The propensity for an individual to sleep at a particular time during a 24-hour period may differ by geographic location with a greater morning preference near the equator.

According to research from both groups, those who preferred the evening reported more depression symptoms than did those with a morning preference, the said.
