Body mass index (BMI) is a measure that calculates body fat content based on a person’s weight and height. It is commonly used to assess if an individual is underweight, normal weight, overweight, or obese. Calculating BMI in kilograms (kg) is particularly important in India, where it is the standard unit of weight measurement.
BMI is relevant as it provides a simple and inexpensive method to screen for potential weight-related health issues. Its widespread use has aided in raising awareness about obesity and its associated risks. A key historical development was the adoption of the BMI classification system by the World Health Organization (WHO) in 1997, standardizing its interpretation globally.
