Research has shown that ‘night owls’, also known as night owls 메이저놀이터, have a higher risk of developing diabetes than ‘morning type’ people ( early birds ) who go to bed early and wake up early .

A research team led by Professor Sina Keanersi of Epidemiology and Biostatistics at Brigham and Women’s Hospital, Harvard University Medical School, collected information from 63,676 female nurses who participated in the ‘Nurses’ Health Study ( NHS ) II’ over 18 years (2009-2017). As a result of the analysis, this fact was revealed, EurekAlert, the science news site of the American Association for the Advancement of Science ( AAAS ) , reported on the 12th.

Of these, 11% were definitely ‘evening people’, 35% were definitely ‘morning people’, and the rest were ‘intermediate types’, neither ‘evening people’ nor ‘morning people’, or were somewhat lacking in being classified as either of the two groups.

During the study period, 1,925 of these people were diagnosed with diabetes.

Excluding lifestyle factors, it was confirmed that overall, ‘evening type’ people had a 72% higher incidence of diabetes than ‘morning type’ people.

The research team explained that even considering all other variables such as eating habits, weight, sleep time, smoking, drinking, exercise, shift work, and family history of diabetes, the risk of diabetes among ‘evening-type’ people was 19% higher than that of ‘morning-type’ people.

Among the people in the study, only 6% of those with the healthiest lifestyles were ‘evening types’. On the other hand, 25% of people with the most unhealthy lifestyle were found to be ‘evening types’.

‘Evening-type’ people were particularly prone to unhealthy habits, such as excessive drinking, poor diet quality, little sleep, and current smoking.

The link between being an ‘evening type’ and having an increased risk of diabetes was only found among nurses who worked during the day and did not work overtime.

‘Evening type’ people had a high risk of diabetes even if their chronotype did not match their working hours . The research team said that this shows that the type of time one chooses is important.

The research team added that unhealthy habits and diabetes risk propensity may create ‘evening-type’ people.

The research team then announced that in the next study, they plan to examine whether there are genetic factors that determine time patterns and whether time patterns are related to cardiovascular diseases in addition to diabetes. The results of this study were published in the Annals of Internal Medicine

, the journal of the American College of Internal Medicine. ) was published in the latest issue.
