Question

According to WHO, what is the BMI (Body Mass Index) classification range for a "pre-obese" individual?

• A. 18.5 -- 24.9
• B. 25.0 -- 29.9
• C. 30.0 -- 34.9
• D. 35.0 -- 39.9

Hint:

BMI 25--29.9 = \textbf{Pre-obese (Overweight)}. Above 30 = Obese category.

Answer 1

The Correct Option is B

Concept: Body Mass Index (BMI) is a measure used to classify individuals based on body weight relative to height. It is defined as: \[ \text{BMI} = \frac{\text{Weight (kg)}}{\text{Height (m)}^2} \] According to the World Health Organization (WHO), BMI categories are:

• Underweight: $<$ 18.5
• Normal weight: 18.5 -- 24.9
• Pre-obese (Overweight): 25.0 -- 29.9
• Obese Class I: 30.0 -- 34.9
• Obese Class II: 35.0 -- 39.9
• Obese Class III: $\geq$ 40.0

Step 1: Understand the classification system.
WHO provides standard BMI ranges to assess health risks associated with body weight.
Step 2: Identify the "pre-obese" category.
The pre-obese category corresponds to individuals who are overweight but not yet in the obese range.
Step 3: Match with the correct range.
The BMI range for pre-obese individuals is 25.0 to 29.9.
Step 4: Conclude the answer.
Thus, the correct answer is 25.0 -- 29.9.
