BMI, or Body Mass Index, is widely used for measuring obesity around the world. However, recent research seems to suggest that the standard classification for people above the age of 40 may need to be readjusted due to inaccuracies.

BMI Doesn’t Account For Body Composition

Simply put, as people age, the composition within their body shifts too. They lose muscle and gain fat, which may result in someone being obese at a lower BMI. This shift in body composition could explain why using BMI to determine obesity may be inaccurate for older adults.

Conducted by researchers from the University of Rome, around 4800 Italian adults between 40 and 80 were divided into groups based on the BMI standards put forth by the WHO (World Health Organization). 

The researchers used X-rays to find that many people over the age of 40 had obesity based on their high amounts of body fat, even if they didn’t reach the traditional BMI threshold for the disease.

What Is The Ideal BMI For People Above 40?

The researchers concluded that a BMI of 27 is a better indicator of obesity than the current WHO standard of 30 for people over 40 years of age. This new BMI cutoff recognizes physical differences between middle-aged and older adults. young people

The biggest takeaway from the study is that we need to reevaluate our use of BMI andit should not be the only tool used to determine a person's metabolic health. Obesity in particular is a chronic condition that’s entirely defined and diagnosed through BMI measures. By using a low BMI cutoff, it could mean that a greater proportion of the population actually has the disease. 

However, the study has certain dimensions that it could not analyze. The research was limited to one area of Italy, and in order to generalize the results, it is necessary to extend the research to other people. Additionally, the authors did not mention diet, physical activity, and sleep health, which may increase obesity risk and interact with age-related changes.
