Step 1: Understanding the Concept:
BMI is a standard tool used to categorize individuals based on their weight-to-height ratio to assess health risks.
Step 2: Key Formula or Approach:
The BMI formula is:
\[ BMI = \frac{Weight\ (kg)}{Height\ (m)^2} \]
Step 2: Detailed Explanation:
The World Health Organization (WHO) provides the following international classifications for adults:
- Underweight: \(< 18.5\)
- Normal Weight: \(18.5 - 24.9\)
- Overweight: \(\ge 25.0\)
- Pre-obese: \(25.0 - 29.9\) (a sub-category of overweight)
- Obese Class I: \(30.0 - 34.9\)
- Obese Class II: \(35.0 - 39.9\)
- Obese Class III: \(\ge 40.0\)
Step 3: Final Answer:
The "pre-obese" range is specifically defined as \(25.0 - 29.9\).
