Improvement of Sleep Apnea and Sleep Patterns May Improve Glycemic Control in Black Patients

Sleep-disordered breathing and fragmented sleep are associated with higher levels of fasting glucose and hemoglobin A1c (HbA1c) in black adults both with and without diabetes, according to new research.

Previous studies have reported a higher prevalence of insulin resistance and type 2 diabetes in black men and women compared with white patients. Disrupted sleep is known to be associated with abnormal blood glucose levels, but few studies have used objective measurements of sleep characteristics to assess their association with blood glucose levels in black adults.

To evaluate this, researchers used data from participants in the Jackson Heart Study, a community-based, prospective cohort study of black men and women. Sleep measurements were examined for their associations with blood glucose levels, and the results were reported as standardized regression coefficients (betas) for each standard deviation (SD) higher level in each sleep measure.
