The Complete Guide to Body Mass Index (BMI)
Body Mass Index (BMI) is a scientifically derived value based on the mass (weight) and height of a person. It is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m². Invented in the 1830s by Belgian statistician Adolphe Quetelet, BMI remains the premier screening tool used by healthcare professionals worldwide to identify weight problems.
1. Why Measure BMI?
BMI provides a quick, inexpensive, and reliable way to screen for weight categories that may lead to health problems. It helps categorize individuals into groups: underweight, normal weight, overweight, and obesity.
Health Risk Indicator: High BMI correlates with increased risk of chronic diseases like type 2 diabetes, heart disease, and high blood pressure.
Public Health Tool: It allows governments and organizations to track obesity trends in populations.
