Cut-Off Values of Anthropometric Indices for the Prediction of Hypertension in a Sample of Egyptian Adults

Open access


Background: Obesity, particularly abdominal adiposity, is closely associated with premature atherosclerosis and many metabolic modifications including insulin resistance dyslipidemia hypertension and diabetes. Cut-off values for abdominal obesity predicting future cardiovascular disease are known to be population specific.

Objective: To identify cut-off points of some anthropometric measurements (BMI, WC, WHR and WHtR) that associated with hypertension in a sample of Egyptian adults.

Subjects and Methods: This is a cross-sectional analysis. The blood pressure of 5550 Egyptian adults was measured (2670 females - 2880 males).The subjects represented different geographic localities and different social classes. Anthropometric measurements including height, weight, waist circumferences, and hip circumferences were also measured by practitioners.

Results: The cut-off values to detect hypertension in females were 30.08 for BMI, 87.75 for WC , 0.81 for WHR and 0.65 for WHtR, and the corresponding sensitivity and specificity were 69.1; 60.7- 80.9; 48.6 -65.3; 53.4 and 61.4; 58.9, respectively. The cut-off values to detect hypertension in males were 27.98 for BMI, 95.75 for WC, 0.92 for WHR, and 0.57 for WHtR and the corresponding sensitivity and specificity were 62.8; 59.9 -71.9; 51.9 -64.6; 55.8 and 59.7; 55.8, respectively.

Conclusion: The BMI, Waist circumference, WHR and WHtR values can predict the presence of hypertension risk in adult Egyptians.
