About this study

Official title: An RCT of Telemedicine Interventions for OSA

This project is investigating whether both moderate-intensity physical activity and dietary weight loss will independently reduce sleep apnea symptoms and improve quality of life.

Read the detailed description

Background/Rationale:

Obstructive sleep apnea/hypopnea (OSAH) is a common chronic disease that is associated with daytime sleepiness, impaired health-related quality of life (QOL), and increased risk of hypertension and cardiovascular disease. The most common treatment is continuous positive airway pressure (CPAP), although adherence to CPAP is poor in more than one-third of patients. Weight loss can clearly lessen the severity of OSAH, but although short-term dietary weight loss can often be achieved it is difficult to maintain. Regular aerobic exercise is associated with a lower prevalence of OSAH in observational studies after adjustment for body habitus, and in two small clinical trials moderate exercise was associated with a substantial decrease in OSAH severity despite little or no weight loss. Demonstrating that dietary weight loss and moderate physical activity, promoted in the home setting, independently improve OSAH severity will have a major impact on the therapeutic approach to OSAH, a disease that is highly prevalent in the VA population.

Objective:

The investigators hypothesize that both moderate-intensity physical activity and dietary weight loss will independently reduce OSAH severity and improve QOL.

Methods:

The proposed study is a randomized clinical trial designed to test the independent effects of the physical activity and diet interventions, with an attention control intervention for subjects not assigned to either active intervention. Subjects will be male and female Veterans with a BMI over 24 kg/m2, with a physician diagnosis of OSAH and apnea-hypopnea index (AHI) >10/hr. The interventions will last six months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change Over 6 Months in Epworth Sleepiness Scale Score

    Epworth Sleepiness Scale score, change in score from baseline to 6 months. Total scores range from 0-24, where higher scores indicate more sleepiness.

    Measured: baseline and 6 months

Secondary outcomes (1)
  1. Change Over 6 Months in Quality of Life

    Quality of life as assessed by the Functional Outcomes of Sleep Questionnaire, change from baseline to 6 months. The potential range of scores for the Functional Outcomes of Sleep total score is 5-20 where higher scores indicate better quality of life. The total score is the sum of the 5 subscale scores (general productivity, social outcome, activity level, vigilance, intimate relationships), which are weighted means ranging from 1-4.

    Measured: baseline and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Physical activity, Diet and Health education in people with Sleep Apnea, run by VA Office of Research and Development at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Feb 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change Over 6 Months in Epworth Sleepiness Scale Score (time frame: baseline and 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2017.
