HealthDay News -- For hospitalized patients, additional sleep and increased sleep efficiency correlate with lower odds of hyperglycemia and impaired fasting glucose, according to research published in Diabetes Care.

Regina H. DePietro, from the Stony Brook University School of Medicine in New York, and colleagues conducted a retrospective analysis of a prospective cohort study involving medical inpatients aged ≥50 years. Two hundred twelve participants were interviewed and their charts were reviewed for demographic data and diagnosis. The correlation between inpatient sleep duration and the proportional odds of hyperglycemia vs impaired fasting blood glucose or impaired fasting blood glucose vs normal blood glucose was assessed.

The researchers found that 34% of the participants had diabetes, and there was no difference in objective inpatient sleep measures for those with vs those without diabetes. Each additional hour of in-hospital sleep correlated with lower proportional odds of a higher glucose category the next morning (odds ratio [OR]: 0.89; P =.043 for hyperglycemia vs elevated and elevated vs normal). Each 10% increase in sleep efficiency correlated with reduced proportional odds of a higher glucose category (OR: 0.82; P <.001).

"Future research should test whether improving patient sleep in hospitals could represent a novel nonpharmacological approach to reducing the risk of hyperglycemia during hospitalization and ultimately lead to better health and reduced health care costs," the researchers wrote.
