About this Research Topic
Body composition assessment is an important tool for diagnosing nutritional status and for prescribing and monitoring dietary and exercise programs. Among the clinical techniques for this assessment, bioimpedance analysis (BIA) is among the preferred ones, due to its relative ease of use, low operational cost, and validity and reliability of results, when properly performed. Thus, many studies have been conducted and published with the aim of strengthening the conceptual assumptions of the technique, which justifies the creation of a Research Topic on the subject in Frontiers in Nutrition.
Bioimpedance analysis parameters can be used to estimate body composition (fat, fat-free mass, total body water and its compartments). In addition, raw measurements including resistance, reactance, phase angle and impedance vector length can also be used to track health-related markers including hydration and malnutrition, and disease prognosis, athletic and general health status. In this sense, the objective of this Research Topic is to improve knowledge on the subject, bringing the state of the art in Bioimpedance Analysis research, based on manuscripts submitted by researchers from all over the world, who develop consistent research on this technique for assessing body composition.
For this Research Topic, we expect original articles and systematic reviews on Bioimpedance Analysis on the following approaches:
• Development and cross-validation of predictive equations of body components, by BIA, using established reference techniques.
• Analysis of body composition by BIA, for the whole body and by segments, for different population groups and at different stages of life.
• Using raw measurements of BIA parameters (resistance, reactance, phase angle, and/or impedance vector length) to track health-related markers, including hydration and malnutrition, and disease prognosis, athletic status, and general health.
• Proposal of normative values and/or cutoff points for BIA parameters, in different health and disease situations, nutritional status and athletic status.
• Validation studies of new equipment for evaluating different body components by BIA.
