A new study suggests that the waist-to-height ratio (WHtR) could be a more accurate predictor of heart disease risk than the widely used body mass index (BMI). Researchers found that individuals with a larger waist relative to their height were significantly more likely to develop calcium buildup in their heart arteries, even if their BMI fell within a healthy range. This means that people who appear “normal weight” by BMI standards could still face elevated cardiovascular risk if their waist size is disproportionate to their height.

The study, published in The Lancet Regional Health, followed more than 2,700 adults and concluded that WHtR was more closely linked to heart disease risk than BMI or waist circumference alone. A WHtR of 0.5 or higher was associated with increased risk, making it a simple and practical tool for both doctors and patients. Unlike BMI, which doesn’t account for fat distribution, WHtR focuses on abdominal fat, which is a key driver of metabolic and atherosclerotic conditions. Experts say this finding could shift clinical practice, as WHtR is easy to measure at home with just a tape measure and offers a clearer picture of cardiovascular health.

While BMI has long been the standard for assessing weight-related health risks, it often fails to distinguish between muscle and fat or identify individuals with normal weight but high visceral
fat. WHtR could help bridge that gap, providing a more accurate and accessible way to monitor heart health. Physicians recommend using WHtR in conjunction with other preventive strategies, such as regular exercise, balanced nutrition and routine screenings, to reduce the risk of heart disease.

Consult your doctor if you have questions or concerns about your body weight or risk of heart disease and other related conditions.
