Increased Risk of Obstructive Sleep Apnea and Poor Sleep Quality Among Older Adults With Type 1 Diabetes: The DCCT/EDIC Study
Authors' conclusion
OSA risk and poor sleep quality were common among DCCT/EDIC participants.
Study context
- Population
- Older adults with T1D in the DCCT/EDIC study; 52% male, mean (SD) age 64 (7) years, mean (SD) diabetes duration 43 (5) years
- Participants
- 963 adults
- Outcome
- Prevalence of sleep problems: intermediate/high OSA risk (STOP-Bang ≥3), poor sleep quality (Pittsburgh Sleep Quality Index >5), excessive daytime sleepiness (Epworth Sleepiness Scale >10)
Methodological detailsquestionnaire-based, logistic regression
- Questionnaire-based
- Logistic regression
Main finding
As reported in the abstract
Prevalence of sleep problems
Increased obstructive sleep apnea (OSA) risk
64%
Poor sleep quality
43%
Daytime sleepiness
10%
Observational data: associations, not effects.
Further findings
Diagnosed OSA and current positive airway pressure device use
- Diagnosed OSA
- 29%
- Current positive airway pressure device use
- 19%
HbA1c and sleep problems
- Each 1% absolute increase (11 mmol/mol) in current or mean HbA1c associated with higher odds of any sleep problem
- 15% to 20%
Diabetes complications and sleep problems
- Cardiovascular autonomic neuropathy associated with higher odds of intermediate/high OSA risk
- Albuminuria and severe hypoglycemia associated with higher odds of poor sleep quality
- Adjusted for age, sex, BMI, and mean HbA1c
