Short and Long Sleep Durations Are Risk Factors for Type 2 DiabetesWhat is the problem and what is known about it so far?A lack of sleep results in high insulin levels and makes it harder to control blood glucose levels. Why did the researchers do this particular study?The researchers wanted to see how sleep duration (or how long a person sleeps) is linked to the risk of getting diabetes. Who was studied?About 1,700 middle-aged and elderly men who took part in the Massachusetts Male Aging Study. How was the study done?The men received regular physical check-ups from 1987-1989 to 2004, and the men regularly reported on how much sleep they were getting. What did the researchers find?Men who reported short sleep duration (less than 5 hours each night) were twice as likely to get diabetes, and men who reported long sleep duration (more than 8 hours each night) were three times as likely to get diabetes. What were the limitations of the study?It was assumed that what each man reported as his average sleep duration was an accurate indication of his overall sleep pattern. It's possible that some men already had diabetes when the study started. What are the implications of the study?How long a person sleeps may indicate whether that person is at risk of getting type 2 diabetes.
