CanCan Body Composition Study

NCT07305753 | Recruiting

• 1 other identifier: PBRC 00006218
• Study Type: observational
• Target: 40
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Healthy Participants; Young Healthy Adults; Elderly (People Aged 65 or More)

Outcome Measures

  Muscle mass

  Single time point

Study Arms (1)

Cross-sectional group

20 young (20-40yo) and 20 older (70+) adults

Eligibility Criteria

• Age: 20 Years - 90 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

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.

You may qualify if:

• 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

You may not qualify if:

• 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
• Taking medications that alter the body's fluid compartments (ex: diuretics)
• Not willing to have biospecimens and imaging stored for future research use.
