Summary

This trial will help researchers learn if obstructive sleep apnea is linked to abnormalities in fat metabolism.

Who is the study for?
This trial is for adults aged 18-70 with moderate-to-severe obstructive sleep apnea who can use a PAP device for at least 4 hours on most nights. It's not for those with diabetes, severe heart conditions, certain sleep disorders, or a BMI over 40. Participants should not be using other OSA treatments or involved in another clinical study.
What is being tested?
The study looks at how fat metabolism might be different in people with obstructive sleep apnea compared to those without it. It involves lifestyle counseling and the use of Positive Airway Pressure (PAP) therapy to see if these interventions affect body energy and sugar usage.
What are the potential side effects?
While the document doesn't list specific side effects, generally PAP therapy may cause discomfort, nasal congestion, dry mouth, or skin irritation where the mask touches the face. Lifestyle counseling typically does not have physical side effects.

Trial Design

3Treatment groups
Experimental Treatment
Active Control
Group I: PAP Therapy and Lifestyle Intervention (Aim 2) GroupExperimental Treatment2 Interventions
Participants in the Aim 1 Group found to have moderate to severe OSA (defined as having a Apnea-Hypopnea Index (AHI) of 15.0 events/hour or more) randomized to this arm will receive the PAP therapy and Lifestyle Intervention for 12 weeks.
Group II: Lifestyle Intervention Only (Aim 2) GroupExperimental Treatment1 Intervention
Participants in the Aim 1 Group found to have moderate to severe OSA (defined as having a Apnea-Hypopnea Index (AHI) of 15.0 events/hour or more) randomized to this arm will receive only the Lifestyle Intervention for 12 weeks.
Group III: No Intervention (Aim 1) GroupActive Control1 Intervention
Participants in this group will not receive an intervention and will only undergo several testing procedures conducted within 3 to 4 weeks to assess OSA severity.
