Hypertriglyceridemic Waist (HTGW) Index Calculator

Hypertriglyceridemic Waist (HTGW) Index: Explanation and Clinical Context The HTGW Index is a simple clinical tool combining waist circumference and fasting triglyceride levels to identify individuals at increased cardiometabolic risk. It was first described by Lemieux et al. in 2007 as a marker for visceral obesity and associated metabolic abnormalities, such as insulin resistance, atherogenic dyslipidemia, and increased risk of type 2 diabetes and cardiovascular disease. Men are considered at high risk if waist circumference >90 cm and triglycerides >177 mg/dL; women are considered at high risk if waist circumference >85 cm and triglycerides >133 mg/dL.

The HTGW Index helps clinicians quickly identify patients who may benefit from lifestyle intervention, closer metabolic monitoring, and cardiovascular risk reduction strategies.
