An Observational Study on the Association Between Body Mass Index and the Palpability of Selected Anatomical Surface Landmarks in Adults
Abstract: Background: Anatomical surface landmarks are essential for clinical examination, anatomical education, and various diagnostic and therapeutic procedures. Their palpability may be influenced by increased subcutaneous adipose tissue associated with higher Body Mass Index (BMI).1-4 Aim: To evaluate the association between BMI and the palpability of selected anatomical surface landmarks in overweight and obese adults. Materials and Methods: A observational study was conducted on 100 adults aged 18-60 years, including 50 overweight participants (BMI 25.0-29.9 kg/m2) and 50 obese participants (BMI 30.0-33.0 kg/m2) according to World Health Organization criteria. The clavicle, acromion process, medial epicondyle of the humerus, styloid process of the radius, facial artery, and brachial artery were assessed by palpation. Palpation pressure (PP) and searching effort (SE) were graded on a three-point ordinal scale (+, ++, +++). Since BMI was a continuous variable and PP/SE were ordinal variables, Spearman's rank correlation was used for statistical analysis. Results: A statistically significant positive correlation was observed between BMI and palpation pressure for all anatomical landmarks (Spearman's ρ = 0.917-0.927, p < 0.0001). BMI also showed a significant positive correlation with searching effort (ρ = 0.718-0.911, p < 0.0001). The strongest associations were observed for the medial epicondyle, styloid process, facial artery, and brachial artery, whereas the acromion process demonstrated the weakest, though still significant, association with searching effort. Conclusion: Increasing BMI was associated with progressively greater palpation pressure and searching effort for identifying anatomical surface landmarks. Arterial landmarks were particularly difficult to identify in individuals with higher BMI. These findings have important implications for clinical examination, anatomy teaching, and procedures that rely on accurate surface landmark identification.
