Sleep is such an important daily activity for all of us. Recent research suggests that irregular sleep is a risk factor for diabetes. Factors such as sleep length, timing, quality, and insomnia have been associated with the risk of developing type 2 diabetes. Additionally, these factors can also impact the levels of blood sugar in people living with diabetes. Researchers of this study looked beyond those factors at the role of sleep regularity on diabetes risk. They analyzed data from 2,107 Hispanic/Latino adults aged 19-64 years who were studied over an average of 5.7 years to look at the link between the sleep regularity and diabetes, insulin resistance (a major risk factor for developing type 2 diabetes), hemoglobin A1c (HbA1c) levels, and how these change over time. They found that irregular sleep was linked to a greater risk of developing diabetes, especially in older people. The effect on insulin resistance, HbA1c, or the need for antidiabetic medication was less clear. These results suggest that sleep regularity can impact diabetes risk. At Sansum Diabetes Research Institute, we are looking at sleep quality and quantity and the effect on diabetes outcomes for local Hispanic/Latino adults.
