Multidimensional Sleep Health, Glycemic Control, and Self-Reported Outcomes in Type 1 Diabetes: A Cross-Sectional Study

Sleep health is multidimensional. While studies have shown associations between certain sleep dimensions and health in type 1 diabetes (T1D), global sleep health has rarely been considered. To examine the associations between individual sleep dimensions and multidimensional sleep health (MSH) on glycemic control and self-reported outcomes in T1D. Data from 116 adults with T1D participating in a sleep study (NCT04506151) were analyzed. Sleep satisfaction and alertness were assessed by questionnaires. Sleep timing, efficiency, duration, and regularity were derived from 7-day actigraphy. A composite MSH score was created by counting "healthy sleep" across these six measures. Glycemic control was assessed by 7-day continuous glucose monitoring and A1C. Self-reported outcomes were collected through questionnaires. After adjusting for covariates, greater sleep irregularity was associated with higher glycemic variability (b=5.048, p
