Short sleep duration increases hyperglycemia risk among inpatients

The risk for elevated blood glucose is increased with short sleep duration among inpatients with and without diabetes, study data show.
“This study suggests that future research is needed to explore whether the sleep disturbances that are typically associated with hospitalization could be an underlying cause of hyperglycemia,” the researchers wrote.
Vineet M. Arora, MD, MAPP, associate professor of medicine at the University of Chicago Sleep, Metabolism and Health Center, and colleagues evaluated data from 212 adult inpatients (mean age, 63.9 years) to determine whether inpatient sleep duration and efficiency are tied to a greater risk for hyperglycemia. Overall, 34% of participants had diabetes by self-report, chart review or diabetes billing code. There was no significant difference between participants with or without diabetes for objective inpatient sleep measures.
The risk for a higher glucose category in the morning was 11% lower for each additional hour of sleep in the hospital the night prior (P = .043). Similarly, the odds of a higher glucose category in the morning was 18% lower for every 10% increase in sleep efficiency.
“In both diabetic and nondiabetic hospitalized patients, patients who have worse sleep in the hospital — both less sleep and poor quality of sleep — are at increased risk for hyperglycemia the next morning,” Arora told Endocrine Today. “What we do not know is if the sleep is the cause of the hyperglycemia. As a hospitalist, one clinical implication is that when you see a patients with poor glycemic control in the hospital or ‘hyperglycemia of hospitalization,’ consider asking about sleep loss and taking steps to optimize the sleep environment for the patient.” – by Amber Cox
