Evaluation of Skinfolds Based Predictive Equations for Estimating Body Fat Percentage in Older Adults: A Comparison Using Digital Adipometer (Lipowise) and Dual-Energy X-Ray Absorptiometry (DXA). [PDF]

open access: yesClin Obes
ABSTRACT Accurate assessment of body fat percentage (%BF) is essential for predicting health risks in older adults, as age‐related changes affect fat distribution and measurement accuracy. While dual‐energy x‐ray absorptiometry (DXA) is a standard reference, it is costly and less accessible.
