Multi-frequency Bioelectrical Impedance for Estimating Total Body Water by Deuterium Dilution

Completed

• Conditions: Total Body Water Assessment
• Interventions: Other: observation

• Registration Number: NCT01607229
• Lead Sponsor: University of Southern California

Brief Summary

SPECIFIC AIM:

Determine the validity of the Biospace bioelectrical impedance devices compared to deuterium water (D2O) measurements.

HYPOTHESIS:

The Biospace Body Composition Analyzers are valid tools for measuring total body water and body composition.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 25

Inclusion Criteria

• men and women between 18-59 years of age

Exclusion Criteria

• Acute illness (infection, recent surgery, trauma).
• pregnancy
• pacemaker or defibrillator
• We would like to standardize the procedures and measurements in the adult population first. Older adults are excluded because by including older adults at this time, we would need to increase the sample size because we believe older adults have greater fluctuations in hydration due to medications, diet, and co-morbidities.

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified
