The Chinese Visceral Adiposity Index (CVAI) is a measure of visceral obesity and correlates with features of the metabolic syndrome such as hypertension.
Parameters:
(1) sex
(2) age in years
(3) body mass index (BMI) in kg per square meter
(4) waist circumference in cm
(5) fasting serum triacylglycerol (TAG) in mmol/L
(6) fasting serum HDL-cholesterol in mmol/L

CVAI for a male =
= SUM(points for the parameters) - 267.93
CVAI for a female =
= SUM(points for the parameters) - 187.32
Interpretation:
• The median CVAI for nonhypertensive Chinese adult males was 71.78.
• The median CVAI for nonhypertensive Chinese adult females was 72.54.
Performance:
• The area under the ROC curve for visceral obesity was 0.83.
