Health Desk-- 24 November, 2018: A new study warns that women who work an erratic mixture of day and night shifts have an ‘especially high risk’ of type 2 diabetes.
We already know the disease can be fuelled by unhealthy lifestyle factors - smoking, eating fast food, scrimping on vegetable, and skipping the gym.
But the new Harvard research, a study of 150,000 nurses over 15 years, found a person’s work schedule can hamper the body’s resilience and control over blood sugar levels, reports the Daily Mail.
They say the findings show a greater need to be conscious of how shift work - particularly on an irregular schedule - can have serious, damaging impacts on a woman’s health.
Over 22 to 24 years of follow-up, 10,915 of the 143,410 nurses were diagnosed as having type 2 diabetes.
For every five years of working rotating night shifts the nurses were almost a third (31 percent) more likely to have been diagnosed with type 2 diabetes.
Study co-author Dr Zhilei Shan, of Harvard T.H. Chan School of Public Health, said: ‘This risk is higher than simply adding the two individual risks for rotating shifts and for poor lifestyle together, indicating that some kind of interaction of the two risk factors adds further risk.’
The study was published in the British Medical Journal.
