Validation of the New HAG-B19 Scale for Measuring Lean & Fat Body Masse

Status Completed

Clinical Trial Summary

Body composition measurement is an important tool for assessing the physical condition of sick or healthy people, as well as for monitoring changes in body composition and physical performance during diet and/or training. Many people self-monitor their body composition using portable and inexpensive assessment tools, but most of them have not been tested for accuracy and precision. This study aims to assess the accuracy and precision of a new portable impedancemeter scale to measure body composition in comparison with proven techniques, such as 4-electrode electrical bioimpedance analysis and dual X-ray absorptiometry.

Clinical Trial Description

This is an observational, prospective, cross-sectional study to evaluate the accuracy and precision of the new HAG-B19 in healthy Western adults. A stratified sampling method is used to recruit a heterogeneous sample of 160 subjects, covering a wide range of ages and body compositions according to gender specific BMI distributions in the population. Volunteers who signed the informed consent form are included in the study. A financial compensation of 50.- CHF is given to each participant (100.- to the 16 participants subjected to the DEXA measurements). The body composition of each subject (FM, LBM and FM%) is assessed with sequential measurements using 3 HAG-B19 and 3 Nutriguard-M® devices (Data Input, Germany). FM% values measured by HAG-B19 are compared to values by Nutriguard-M® to assess the accuracy and precision of HAG-B19 (main objective). Intra- and inter-device variability are obtained by comparing the 3 repeated measurements and the 3 HAG-B19 devices (secondary objective). In a subgroup of 16 individuals, the FM% values measured by HAG-B19 are compared to DEXA measurements (secondary objective). Pearson correlations and Bland-Altman graphs are performed to assess the agreement of the measurements between the devices and paired t-tests are used to determine if there is a bias between the devices. The significance of the statistical analysis is fixed at p <0.05. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
