Study Shows: Waist Circumference Predicts Mortality Risk in Older Adults Better Than BMI

Why waist circumference is more meaningful

Researchers from the US have now further substantiated this connection with current data. The team was able to show that BMI reflects mortality risk in retirees less reliably than long assumed. Instead, another parameter moves into the foreground: waist circumference.

A larger waist circumference is considered a marker for visceral fat – fat deposits in the abdominal area that place particular strain on metabolism and blood vessels. The researchers argue that именно этот параметр отражает кардиоваскулярный риск у пожилых людей реалистичнее, чем только ИМТ.

The findings support a growing number of voices in geriatrics and nutritional medicine calling for a move away from pure BMI screening in older adults. Complementary measurements such as the waist-to-hip ratio or waist circumference alone could play a more important role in preventive care for older people in the future.

What the findings mean for medical practice

At the same time, the authors emphasize that a low BMI in old age should not automatically be interpreted as a sign of good health. It may also indicate sarcopenia – the simultaneous loss of muscle mass and weight, which is likewise associated with a poorer prognosis. A high BMI, by contrast, may in this phase of life simply reflect more robust muscle mass.

For clinical practice, this means: general practitioners should pay greater attention to body composition and to simple measurements such as waist circumference in patients of retirement age, rather than relying solely on BMI. Only in this way can risks be identified early and treated in a targeted manner.

What still needs to be clarified

The study authors point out that further research is needed to determine the precise threshold values for waist circumference in older women and men. The interaction with chronic diseases, medication use, and physical activity also needs to be examined more closely.

Overall, the investigation provides an argument for assessing individual health risks in old age less by a single metric. A holistic view of body build, muscle mass, and fat distribution is increasingly regarded as the more meaningful approach – especially for a growing group of older people who want to live healthily for as long as possible.
