Body Mass Index (BMI), a numerical value, is calculated to categorise and assess body weight in relation to height. This globally used metric is crucial for tracking obesity and associated health conditions.
The BMI formula, introduced in the 19th century by Belgian mathematician Lambert Adolphe Jacques Quetelet, is universally recognised as an effective tool to assess nutritional status. Its simplicity, ease of calculation, and relevance for both clinical and research purposes have made it an essential health parameter.
