About this study

Official title: The Effect of Increased Soy Protein Intake on Bone Metabolism

The aim of the present study was to investigate the effects of soy and soy plus isoflavones on bone mineral Density and physical performance in post menopausal women.

Read the detailed description

Post menopausal estrogen deficiency causes physiologic changes in body composition including decreased lean body weight and bone mass. A decrease in muscle strength along with osteoporosis puts post menopausal women at a high risk of hip fractures causing considerable mortality and morbidity. Estrogen use has been shown to reduce bone density loss and increase muscle strength but given the concerns regarding its use, patients are looking for alternatives such as Soy isoflavones. Most human studies on the effect of Soy on bone mineral density (BMD) in post menopausal women have been short term i.e. 3-6 months and failed to provide conclusive evidence. There is no evidence of its effects on physical performance.

The aim of the present study is to investigate the effects of 25g of soy protein alone or with 90mg of isoflavones on bone mineral Density and physical performance indices in post menopausal women over a duration of 2 years.

Questions about this trial

What is this clinical trial studying?

A study testing Soy protein in people with Osteoporosis, run by Creighton University 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 2 inclusion and 4 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 21 Apr 2008. 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. Some participants in this study may receive a placebo. 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.

What does the primary outcome measure?

Bone Mineral Density (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00661856, 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 21 Apr 2008.
