question 12
what measurement system is commonly used to classify individuals as having a \healthy weight\, \overweight\, or \obese\?
waist - to - hip ratio
body mass index
circumference measurements
body fat percentage

Explanation:

The Body Mass Index (BMI) is the most commonly used measurement system to classify individuals as having a healthy weight, overweight, or obese. It is calculated using a person's weight (in kilograms) divided by the square of their height (in meters), i.e., $BMI = \frac{weight(kg)}{height(m)^2}$. Waist - to - hip ratio, circumference measurements, and body fat percentage are also related to body composition and health but are not the primary system for classifying weight status in the general population like BMI is.

Body mass index
