Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 20 to 90 years
- All sexes
- Healthy volunteers accepted
- Adult, Older adult
Study population: The participants will be community dwelling, have a self-reported ability to walk one-quarter of a mile and climb 10 steps without difficulty, self-reported ability to perform activities of daily living (ADLs) without difficulty, and no life-threatening conditions or diseases that would alter their body composition from what is typical for their age, sex, and BMI. Overall, participants must be ambulatory, able to withstand lying flat on the DXA table for up to 10 minutes, stand without aid for 2 minutes, weigh less than 440 lbs and be in generally good health.
Who may be able to join
- Being either male or female
- Being an adult >20 - <40 or >70 years of age.
- Having a body weight of less than 440 pounds
- Being willing to comply with the study procedures
- Not having a chronic illness (e.g., diabetes, cancer, etc.)
- Must be willing to have biospecimens and imaging stored for research use
Who cannot join
- Being pregnant, attempting to become pregnant, or breastfeeding
- Having medical implants such as a pacemaker or metal joint replacements
- Having had a mastectomy, breast reduction, or breast implants
- Having hair that cannot fit in a swim cap
- Having a body weight greater than 440 pounds

About this study
The aim of this study is to develop a dataset with reference body composition measurements using criterion methods. This dataset will be used to develop new protocols to study patients with cancer. Obtaining measurements of sodium bromide (NaBr), deuterium dilution (D2O), and D3-Creatine in a stratified sample of adults will determine the accuracy (and precision) of the available devices for ECW, TBW, and skeletal muscle mass measurements.

Questions about this trial
What is this clinical trial studying?
An observational study of Healthy Participants and Young Healthy Adults, run by Pennington Biomedical Research Center 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 6 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 26 Dec 2025. 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. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Steven B Heymsfield, MD (2257632541, steven.heymsfield@pbrc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Skeletal Muscle Mass (time frame: Single time point). It is what the study was designed to measure, not a finding.
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 26 Dec 2025.
