Bioimpedance: From Body Composition Assessment to Emerging Technologies in Clinical Nutrition
This review examines the physical foundations, predictive models, emerging technologies and recent research trends in bioimpedance for clinical nutrition. A bibliometric analysis of cumulative scientific production from 1980 to 2025 shows that weighted logistic models provide a good descriptive fit to the evolution of the literature (R2 ≥ 0.999). Bioimpedance research remains in an expanding phase, with its projected inflection point lying beyond 2026. These fits are descriptive and model-dependent: high coefficien …
