Purpose: The purpose of this study was to examine the relationship between sleep duration and glycemic control in adult Hispanic patients with uncontrolled type 2 diabetes. Methods: This cross-sectional study used baseline data from 317 Hispanic adults with uncontrolled type 2 diabetes who participated in a randomized controlled trial testing a peer support intervention to improve diabetes control. To be eligible, participants had to be 18 years or older and have A1C >7% in the 3 months prior to randomization. Glycemic control was assessed by A1C ascertained through medical chart review; higher A1C levels reflected poorer glycemic control. Sleep duration (hours/night), diabetes control behaviors, and demographics were obtained by interviewer-administered questionnaire. We used multivariable generalized linear models to estimate the association between sleep duration and glycemic control. Results: Forty-three percent of participants reported sleeping fewer than 7 hours per night. Sleep duration (hours/night) was inversely associated with A1C levels; however, the relationship was no longer statistically significant after adjusting for insulin status. Conclusions: Sleep duration was not significantly associated with glycemic control in this sample of Hispanic adults with uncontrolled type 2 diabetes when adjusting for insulin. Future research should continue to explore this relationship among Hispanic adults with diabetes using an objective measure of sleep duration and a larger sample of Hispanic adults with both controlled and uncontrolled type 2 diabetes to determine if these results hold true.
