NEW ANTHROPOMETRIC MEASUREMENTS AND METABOLIC RISK ASSESSMENT IN PRIMARY HYPERPARATHYROIDISM: THE ROLE OF BODY ROUNDNESS INDEX

Introduction: Anthropometric indices are linked to metabolic parameters and chronic diseases. While body mass index (BMI) is a widely used anthropometric index, the Body Roundness Index (BRI), which assesses visceral adiposity and total body fat, is less commonly used in studies. This study examined the relationship between metabolic risk markers and BRI patients with primary hyperparathyroidism. Methods: A total of 71 patients with primary hyperparathyroidism were included in the study, and there was no control group. BRI was calculated using a mathematical formula: 364.2 − 365.5 × √(1 − [waist circumference(cm) / 2π]2 / [0.5 × height(cm)]2. Gender differences in BRI were assessed using independent samples t-tests, while correlations with metabolic parameters were analyzed. One-way ANOVA was applied to evaluate differences in BRI among groups with varying cholesterol levels. Results: Females had significantly higher BRI values (6.56±1.79) than males (4.84±1.05) (t=-3.725, p=0.000). Among participants, 56.3% had normal cholesterol levels, 38.0% were borderline high, and 4% had high cholesterol. A weak but significant correlation was found between BMI (r=0.368, p<0.005) and BRI (r=0.394, p<0.005) and total cholesterol levels. Individuals with normal cholesterol levels had lower BRI values (5.62±1.60) compared to those with borderline high (6.70±1.78) and high (7.68±2.26) levels (F=4.876; p=0.011). Conclusions: Although BRI, an alternative anthropometric index that can be used in addition to BMI, has shown potential as a metabolic risk marker in patients with primary hyperparathyroidism, further research is needed involving different patient groups and metabolic risk markers.
