About this study

To test the hypothesis that clinically inapparent sleep-disordered breathing was associated with blood pressure elevation, impairment of health-related quality of life, and depression.

Read the detailed description

BACKGROUND:

The health impact of disordered breathing during sleep among middle-aged and older men and women in the general population had not been well studied, and the need for treating relatively mild degrees of sleep-disordered breathing was unknown in 1994. The study was the first population study which examined the effect of sleep-disordered breathing on these health outcomes. The study sought to establish the prevalence of clinically important sleep-disordered breathing among middle-aged and older men and women and to provide quantitative data to serve as the basis for selecting patients for screening and deciding which patients might benefit from therapeutic intervention.

DESIGN NARRATIVE:

The study evaluated the hypothesis that clinically inapparent sleep-disordered breathing was associated with blood pressure elevation, impairment of health-related quality of life, and depression. The study used the Veterans Administration Normative Aging Study (NAS) population, which consisted of approximately 1,700 community-dwelling-men who returned for examination every three years. Respiratory function was assessed during sleep among these men and their wives using a validated method for home sleep monitoring. Blood pressure, health-related quality of life, and depression score were also assessed in the home. The potential associations of sleep-disordered breathing with hypertension, impaired health-related quality of life, and depression were evaluated, and the possibility that these relationships differed between men and women was examined.

The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiovascular Diseases and Hypertension, run by National Heart, Lung, and Blood Institute (NHLBI).

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

Who may be eligible to take part?

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 16 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

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 16 Mar 2016.
