What is the primary limitation of skinfold tests on an obese client?

Skinfold tests measure the thickness of skinfolds at specific sites on the body to estimate body fat percentage. However, in obese clients, the distribution and composition of fat can complicate this measurement. For individuals with higher body fat percentages, the subcutaneous fat layer may become so thick that it is difficult to accurately capture with calipers, which can lead to underestimations of body fat levels. This is because skinfold measurements typically assume a certain distribution of fat and may not account for the differences in fat distribution seen in obese individuals.

Furthermore, the accuracy of skinfold measurements can be influenced by multiple factors, including the skill of the person administering the test and the locations selected for measurement. Variability in fat distribution can also lead to inconsistent readings. Thus, the primary limitation is that the skinfold test may not be accurately reflective of true body fat levels for obese clients, which can impact the assessments and recommendations based on those figures.
