Boston: According to a new study, staying up late at night significantly increases the risk of diabetes in women, by almost 20 times .Researchers at Brigham and Women’s Hospital in Boston, USA, examined data from approximately 64,000 middle-aged nurses between 2009 and 2017.The study revealed that women who stay up late at night and wake up late in the morning have a higher risk of developing diabetes in comparison to those who wake up early. The researchers found that women who stay up late tend to have more unhealthy lifestyle habits, such as less exercise, among other factors, which contribute to the increased risk of diabetes.Experts explained that women who stay up late at night often have access to more opportunities for unhealthy lifestyle choices, such as less physical activity, compared to those who follow a different sleep pattern. The data collected from the nurses included information about their sleep habits, diet, weight, body mass index (BMI), sleep duration, tobacco use, alcohol consumption, and physical activity.To determine the risk of diabetes in these women, researchers also examined their medical records. The study found that women who stayed up late at night were 11% more likely to develop evening chronotype (being active during evening hours) and 35% more likely to develop morning chronotype (being active during morning hours). The rest of the individuals were categorized as intermediate, meaning their sleep patterns did not align strictly with either morning or evening chronotypes. Researchers concluded that the study revealed a 19% increased risk of diabetes associated with evening chronotype.
