P130 TO ASSESS THE SENSITIVITY OF ANKLE BRACHIAL INDEX, WAIST TO THIGH RATIO AND HEIGHT TO WAIST RATIO AS A PREDICTOR OF HYPERTENSION

Materials and Methods: This cross-sectional study included 1000 subjects and spanned from August 2021 to December 2023. It compared Height to Waist Ratio (HtWR), Ankle Brachial Index (ABI), Waist to Thigh Ratio (WTR), and Wrist to Arm Ratio (WAR) against established markers like Waist to Height Ratio (WHtR), Waist to Hip Ratio (WHR), and Body Mass Index (BMI) to assess their effectiveness in measuring body composition. Results: Out of 750 participants, 40% (n=400) were males and 60% (n=600) were females. Among them, 44% (n=440) were non-hypertensive, while 56% (n=560) were hypertensive. For males, HtWR (AUROC: 0.677) and Inverse ABI (AUROC: 0.611) showed superior predictive capability for hypertension compared to other measures. Conversely, among females, Waist to Thigh Ratio (AUROC: 0.669) was the most effective predictor. Cut-off values for WTR in females were 1.55, while for males, HtWR and Inverse ABI were 2.3 and 2.84, respectively. Conclusion: Among males, height to waist ratio and inverse ABI proved more reliable for predicting hypertension, while in females, waist to thigh ratio was more sensitive. Among males, HtWR (AUROC: 0.677) and Inverse ABI (AUROC: 0.611) were superior predictors of hypertension, while females showed a higher predictive capability with Waist to Thigh Ratio (AUROC: 0.669). Specific cut-off values were established: 1.55 for WTR in females, and 2.3 for HtWR and 2.84 for Inverse ABI in males. These gender-specific findings inform tailored hypertension risk assessment strategies. This study suggests incorporating inverse ABI into both clinical and community-based hypertension screenings to enable earlier detection.
