简要总结
The aim of this study is to acquire impedance measurements of the adult human body with a novel bioimpedance device housed inside a watch case and to compare derived estimates of body composition measured by dual-energy x-ray absorptiometry (DXA) and other bioimpedance analysis (BIA) systems.
详细描述
Aims:
The study hypothesis will be tested as follows. Each subject will complete novel BIA, DXA, anthropometric, and other BIA studies at PBRC and the University of Hawaii Cancer Center. The acquired data will then be used to accomplish the specific aims:
- Identify the associations of body composition acquired by the novel BIA devices with those estimated by DXA and other BIA systems.
- Describe the precision and accuracy of the novel BIA-derived body composition estimates.
Subjects and Design:
We will recruit a stratified sample of 100 participants recruited from the Baton Rouge metropolitan area for this study over a span of 6 months. Participants will be further subdivided into cohorts based on gender, age, and BMI.
