Poor Sleep And Diabetes: The Worse You Sleep, The Higher Your Type 2 Diabetes Risk
A new study published Thursday in Diabetologia reaffirms the importance of a good night’s sleep in order to stay healthy.
Analyzing the medical histories of more than 100,000 female nurses, the study authors found those who reported frequently having trouble sleeping were 45 percent more likely to develop type 2 diabetes over the course of a decade than those who didn’t. For the unfortunate nurses who reported having sleep apnea, sleeping fewer than six hours, and often working the graveyard shift in addition to sleeping difficulty, that risk increased more than four-fold. Though poor sleepers were also more likely to have underlying health problems like hypertension or high BMI, these factors only partially explained the association between sleep troubles and diabetes.
“Our findings highlight the importance of sleep disturbance in the development and prevention of type 2 diabetes,” the authors concluded.
The authors utilized data from two of the longest-running observational studies in existence: The Nurses’ Health Study I and II, which began in 1976 and 1989 respectively. Every two years, NHS volunteers are mailed questionnaires about their “lifestyle practices and other exposures of interest, as well as the incidence of disease.” For the purposes of their study, the current authors solely focused on the 133,353 women who weren’t already diagnosed with preexisting conditions like cancer, heart disease and diabetes by the year 2000, answered questions about their sleeping habits, and remained in the NHS for up to an additional ten years.
