Read the detailed description
BACKGROUND:
The NCEP is a major public education program providing advice to physicians and the public on management and prevention of coronary heart disease. However, data supporting the advice are derived primarily from middle-aged men, with less data available for women and older individuals. Furthermore, there have been recent reports that when low saturated fat diets such as the NCEP Step One and NCEP Step Two diets, are followed, HDL-cholesterol is lowered as well as LDL-cholesterol.
DESIGN NARRATIVE:
Randomized, controlled, factorial design powered for men and women separately. One hundred eighty postmenopausal women, 45 through 64 years of age, and 197 men, 30 through 64 years of age, who had low high-density lipoprotein (HDL) cholesterol levels (< or =59 mg per deciliter in women and < or =44 mg per deciliter in men) and moderately elevated levels of low-density lipoprotein (LDL) cholesterol (>125 mg per deciliter but <210 mg per deciliter in women and >125 mg per deciliter but <190 mg per deciliter in men) were enrolled. The subjects were randomly assigned to aerobic exercise, the NCEP Step 2 diet, or diet plus exercise, or to a control group, which received no intervention. The four interventions were delivered for one year: usual care (written dietary materials only with delayed intervention optional), exercise only (supervised, progressive aerobic exercise program at least three times per week), diet only (group and individual dietary instruction on the NCEP Step One/Step Two diet delivered by registered dietitians), and diet plus exercise. At baseline and at the end of one year, measurements were made of blood lipids and lipoproteins, plasma glucose and insulin, glucose tolerance, blood pressure, body composition through hydrostatic weighing and waist and hip circumterences, aerobic fitness (VO2 max), and five unannounced 24-hr. recalls. The primary outcomes measured was HDL-cholesterol, major secondary endpoints included LDL-C, LDL-C/HDL-C ratio, and triglycerides.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing diet, fat-restricted and exercise in people with Cardiovascular Diseases and Heart Diseases, run by Stanford University.
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 12 Jan 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.
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?
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?
On the ClinicalTrials.gov record for NCT00000598, which also lists 1 linked publication.
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 12 Jan 2016.
