Study Stopped
The study did not reach 50% of the proposed sample size. Recruitment slow because persons not interested in being randomized to a sham-control CPAP device or not CPAP naïve.

Brief Summary
Diabetes self-management is important to help adults with type 2 diabetes achieve glucose control. Obstructive sleep apnea often co-exists with type 2 diabetes and may act as a barrier to diabetes self-management and glucose control. We will examine if treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP), combined with diabetes education, results in improved diabetes self-management and glucose control.

Outcome Measures
Primary Outcomes (1)
HbA1C Level
Glycated hemoglobin test that estimates the blood glucose level over last 2 to 3 months. Higher scores indicate worse diabetes control.

Secondary Outcomes (10)
Fructosamine Level
baseline, 6 weeks, 12 weeks
Diabetes Diet Adherence
baseline, 6 weeks, 12 weeks
Diabetes Knowledge
baseline,12 weeks only
Self-Monitoring of Blood Glucose (SMBG)
baseline, 6 weeks, 12 weeks
Steps Walked
baseline, 6 weeks, 12 weeks

Study Arms (2)
Active CPAP treatment
EXPERIMENTALTreatment of obstructive sleep apnea with continuous positive airway pressure (CPAP)
Sham-CPAP
PLACEBO COMPARATORDevice that appears like the treatment of obstructive sleep apnea, a continuous positive airway pressure device, but that does not provide treatment.
Interventions
CPAP is a device that has a mask worn over the nose that is attached to a device that provides positive airway pressure. CPAP is worn while sleeping, it splints open the airway and prevent apneas (cessation of breathing) and hypopneas (reduced airflow while breathing).
Sham-CPAP is a device that has a mask worn over the nose that is attached to a device that looks and sounds like CPAP however it does not provide positive airway pressure. Sham-CPAP is worn while sleeping, it does not splint open the airway and prevent apneas (cessation of breathing) and hypopneas (reduced airflow while breathing).
Diabetes Education will be delivered to participants in both the CPAP group and the Sham-CPAP group. The education will be based on ADA and AADE guidelines and consist of 2 in-person sessions (90 minutes and 60 minutes) and 3 follow-up phone calls 9about 15 minutes each)
Eligibility Criteria
You may qualify if:
- Suboptimal glucose control (A1C ≥ 6.5%)
- Moderate-to-severe obstructive sleep apnea (apnea + hypopnea index \>= 10/hour)
- age 18 years and older
You may not qualify if:
- Poor glucose control (A1C \> 11)
- Type 1 or gestational diabetes
- Sleep duration \< 4 hrs
- Acute medical or surgical conditions or hospitalization ≤ 3 months
- Oxygen or bi-level PAP required
- Prior CPAP or persons in household with CPAP
- Employed in safety sensitive job
- Pregnant

Limitations and Caveats
Recruitment was negatively affected by a large number of persons screened who were ineligible because of either their, or a family member, having prior CPAP treatment. Recruitment was also affected by persons who did not want the possibility of being randomized to be on a sham-CPAP device for 12 weeks.
