The Edmonton Obesity Staging System (EOSS) score is a stronger predictor of all-cause mortality than BMI classification alone, independently predicting increased mortality risk even after adjusting for metabolic syndrome and hypertriglyceridemic waist.

If you have overweight or obesity, your risk of death is better predicted by your overall health status (like blood pressure, diabetes, or mobility) than by your BMI alone. Doctors should use a comprehensive staging system (like EOSS) to assess your risk and prioritize treatments, rather than relying solely on weight metrics.
