About this study

To determine the effects in moderately obese subjects of weight loss by combined dieting and exercise training on risk factors for coronary artery disease including lipoprotein lipids, apoproteins and blood pressure.

Read the detailed description

BACKGROUND:

Evidence appears to be fairly conclusive that obesity has adverse effects on health and longevity when the relative body weight is 40 percent above desirable weight based on insurance industry tables of weights. The close association between obesity, hypertension, hypercholesterolemia, non-insulin dependent diabetes mellitus, an excess of certain cancers and other medical problems makes it imperative that interventions be directed to change the lifestyles and behaviors of individuals who are overweight. The Stanford Weight Control Project (SWCP) trial examined the effects of weight loss on cardiovascular disease risk factors.

The Stanford Weight Control Project (SWCP) randomized 155 overweight, sedentary, non-smoking men, aged 30-59 years, to one of three groups. Fifty-one were assigned to weight loss through dieting, 52 to weight loss through exercise, and 52 to a control, non-intervention group. Follow-up continued through July 1989.

DESIGN NARRATIVE:

Subjects were randomized to a control group, a hypocaloric National Cholesterol Education Program (NCEP) diet, or to a hypocaloric NCEP diet with exercise. One hundred nineteen of the men and 112 of the women returned for testing after one year.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing diet, reducing, exercise and diet, fat-restricted in people with Cardiovascular Diseases and Coronary Disease, 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 26 Jun 2013. 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 NCT00000519, which also lists 15 linked publications.

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 26 Jun 2013.
