The methodology for determining an individual’s Body Mass Index involves a straightforward mathematical calculation. This calculation requires two key measurements: the individual’s weight, measured in kilograms, and their height, measured in meters. The weight value is then divided by the square of the height value. For instance, if a person weighs 70 kilograms and is 1.75 meters tall, the calculation would be 70 divided by (1.75 * 1.75), resulting in the BMI value.
This index provides a readily accessible metric for assessing whether an individual’s weight is within a healthy range, underweight, overweight, or indicates obesity. Its development offered a simple and inexpensive method for large-scale population studies related to weight and health risks. While not a definitive diagnostic tool, it serves as a valuable initial screening measure for healthcare professionals and individuals alike. Understanding where one falls within the associated BMI categories can motivate proactive health management and informed discussions with medical providers.
