Waist-to-Height Ratio Better Indicator Than BMI

New research has found that waist-to-height ratio is a more accurate and reliable measure of age-related obesity risk than the commonly used body mass index (BMI). While BMI calculates obesity based on a person’s weight and height, it does not take into account fat distribution in the body. Waist-to-height ratio, on the other hand, measures how fat is stored around the waist relative to a person’s height, which researchers say is a stronger predictor of health risks, especially in older adults.

As the UK’s population continues to age, obesity and obesity-related diseases such as diabetes, heart disease, and stroke are placing an increasing burden on the National Health Service (NHS). According to experts, identifying obesity risk early is key to preventing serious health problems and reducing pressure on healthcare services.

Researchers suggest that if doctors and health authorities use waist-to-height ratio more widely as a screening tool, they could detect older adults who are at higher risk sooner. This would allow for timely advice, lifestyle changes, and medical interventions to prevent obesity-related illnesses before they become severe.

The study highlights that even people who appear to have a healthy BMI may still be at risk if they carry excess fat around their waist. This finding is particularly important for older adults, who may face higher health risks even with moderate weight gain.

Experts believe that adopting waist-to-height ratio in routine health checks could transform how obesity is monitored and managed, making preventive care more targeted and effective for the ageing population.
