Multidimensional Sleep Health, Glycemic Control, and Self-reported Outcomes in Type 1 Diabetes: A Cross-sectional Study
Authors' conclusion
Sleep irregularity likely drives the association between MSH and glycemic control, while poor sleep satisfaction, lower efficiency, and later timing contribute to the association between MSH and depression. These results highlight the importance of comprehensive sleep health evaluation in T1D.
Study context
- Population
- Adults with T1D participating in a sleep study; sleep dimensions by questionnaires and 7-day actigraphy, glycemic control by 7-day CGM and HbA1c
- Participants
- 116 adults
- Outcome
- Associations of sleep dimensions and multidimensional sleep health (MSH) with glycemic control and self-reported outcomes, adjusted for covariates
Main finding
As reported in the abstract
- Greater sleep irregularity: higher glycemic variability
- b = 5.048, P < .01
- Greater sleep irregularity: less time in range (TIR)
- b = −10.806, P < .01
- Greater sleep irregularity: higher time above range (TAR)
- b = 7.40, P < .05
- Greater sleep irregularity: higher HbA1c
- b = .365, P < .05
- Poor sleep satisfaction: higher diabetes distress
- b = .29, P < .05
- Poor sleep satisfaction: higher depression
- b = 3.59, P < .05
- Later sleep timing: higher depression
- b = 1.545, P < .05
- Lower sleep efficiency: higher depression
- b = 1.545, P < .01
- Worse multidimensional sleep health (MSH): lower TIR
- b = 2.376, P < .05
- Worse MSH: higher TAR
- b = −2.38, P < .05
- Worse MSH: higher HbA1c
- b = −.177, P < .01
- Worse MSH: depression
- b = −1.275, P < .05
Observational data: associations, not effects.
