Definition
Der Body-Mass-Index (BMI) ist ein Screening-Wert, der durch Division des Körpergewichts in Kilogramm durch das Quadrat der Körpergröße in Metern berechnet wird (kg/m²).
Erklärung
Developed by Belgian statistician Adolphe Quetelet around 1832, BMI was intended as a population-level statistical tool, not an individual diagnostic. The WHO defines underweight as BMI below 18.5, normal weight as 18.5–24.9, overweight as 25–29.9, and obese as 30 and above. BMI does not distinguish muscle from fat and has been criticized for systematically misclassifying athletes and underestimating health risks in some ethnic groups.
