758-P: Daily Blood Glucose Predicted by Sleep, Exercise, and Relationship Quality in Young Married Couples with Type 1 Diabetes

T1DM care is critical during emerging adulthood (18-30 years of age), as this age group is known for inconsistent T1DM management, beginning complications, and frequent hospital visits, along with higher hemoglobin A1c levels than any other age group. Complications related to maintaining blood glucose may be due to emerging adults transitioning to new environments, where T1DM management patterns change and less time is spent with blood glucose “in range” (the time in which glucose levels are in an ideal range). An important new environment for emerging adulthood with T1DM is the transition to living with a partner resulting in new patterns of diabetes management, sleep and exercise patterns, and relationship processes. Using data from a pilot study of 15 young married couples, we examined daily glucose levels as predicted by daily sleep, daily physical activity, and baseline relationship quality. We controlled for relationship length, income, education, time since diagnosis, and baseline hemoglobin A1c levels. Sleep and physical activity were measured using actigraphy watches, and daily glucose levels were measured using continual glucose monitors (where available). Findings suggest that sleep efficiency is linked with higher average daily blood glucose readings. Further, this link was moderated by relationship quality such that those with higher relationship quality and higher sleep efficiency also reported higher average glucose levels. Results from this preliminary study suggest that better sleep and relationship processes are associated with higher average blood glucose levels.
