About this study

Official title: Influence of Dairy on Bone Accrual and Bone Size and Fat and Lean Mass in Early Pubertal Overweight vs. Healthy-weight Boys and Girls

Building stronger bones during pubertal growth could reduce lifelong fracture risk. This project is an 18 month dairy intervention study for overweight and healthy weight 4th-8th grade boys and girls. Half of the girls will receive dairy products to add to their habitual diet (milk, yogurt, and cheese) to equal three products per day, while the other half will remain on their normal diet. All participants will attend four study visits, each 6 months apart. At these visits height, weight, bone density and geometry, and fat and lean mass will be measured. This study aims to show that meeting calcium requirements by eating dairy products builds bigger, stronger bones, and that this effect may be enhanced in overweight boys and girls. The effect of the dairy intervention on body fat, lean mass, and weight, as well as the mechanisms and predictors of changes in bone mass and size and body composition will also be evaluated.

Questions about this trial

What is this clinical trial studying?

A study testing Increased Dairy Consumption in people with Healthy, run by Purdue University at 2 sites 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 4 inclusion and 3 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 9 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

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?

Changes in bone density and geometry as measured with DEXA and pQCT. (time frame: 18 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 NCT00635583, 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 9 May 2018.
