Generation of Prediction Equations to Analyze Body Composition of Obese Adults Based on BIA

July 22, 2019 updated by: Seca GmbH & Co. Kg.

Generation of Prediction Equations to Analyze Body Composition of Obese Adults Based on Bioelectrical Impedance Analysis (BIA)

The study was based on the clinical trial BCA-01 (NCT01368640) "Generation of prediction equations to analyze body composition of adults based on Bioelectrical Impedance Analysis (BIA)" and implicates an extension of the study collective. Aim of the study is to develop prediction equations for calculating FFM, TBW, ECW and SMM based on the gold standard reference methods ADP, DXA, MRI, D2O and NaBr on the one hand and measurement data of the BIA devices on the other hand.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
BIA 5 and 50 kHz
Time Frame: 15 minutes
Bioelectrical Impedance of 5 and 50 kHz for one body side
15 minutes
BIA 50 kHz
Time Frame: 15 minutes
Bioelectrical Impedance of 50 kHz for all 4 extremities
15 minutes
Total body water
Time Frame: 15 minutes
Total body water (TBW) by deuterium (D2O) dilution
15 minutes
Extracellular water
Time Frame: 15 minutes
Extracellular water (ECW) by NaBr dilution
15 minutes
Fat-free mass
Time Frame: 1 hour
Fat-free mass by a 4-compartment model based on dual energy x-ray absorption (DXA), air displacement plethysmography (ADP), D2O dilution and weight
1 hour
Skeletal muscle mass
Time Frame: 1 hour
Skeletal muscle mass (SMM) by magnetic resonance imaging (MRI)
1 hour
Visceral adipose tissue
Time Frame: 1 hour
Visceral adipose tissue VAT by magnetic resonance imaging (MRI)
1 hour

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Complete BIA
Time Frame: 15 minutes
Bioelectrical Impedance of 1, 1.5, 2, 3, 7.5, 10, 15, 20, 30, 75, 100, 150, 200, 300, 500, 750 and 1,000 kHz for all body segments: right arm, left arm, right leg, left leg, trunk, right body side and left body side.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 23, 2015

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
February 24, 2016

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
