kehamassiindeksil

Kehamassiindeks, often abbreviated as KMI or BMI in English (Body Mass Index), is a measure derived from the mass and height of a person. It is defined as the body weight in kilograms divided by the square of the height in meters. KMI provides a general indication of whether a person has a healthy weight for their height.

The formula for KMI is: KMI = mass (kg) / height (m)^2. For example, a person weighing 70 kilograms and standing 1.75 meters tall would have a KMI of approximately 22.86.

KMI is categorized into several ranges to interpret the result. A KMI below 18.5 is generally considered underweight. A KMI between 18.5 and 24.9 is considered normal or healthy weight. A KMI between 25.0 and 29.9 indicates overweight. A KMI of 30.0 or higher suggests obesity. These categories are further subdivided in some classifications.

While KMI is a widely used screening tool, it has limitations. It does not distinguish between muscle mass and fat mass, meaning individuals with a high muscle mass, such as athletes, may have a high KMI without being unhealthy. Similarly, KMI does not account for fat distribution, which can also be an important factor in health. Therefore, KMI should be considered as a preliminary indicator and not a definitive diagnostic tool. Health professionals often use KMI in conjunction with other measurements and assessments.
