At how many standard deviations above the WHO Child Growth Standards median is an individual considered obese?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

An individual is considered obese when their growth measures, typically body mass index (BMI) for children, are at least 3 standard deviations above the median of the World Health Organization (WHO) Child Growth Standards. This benchmark indicates a significant excess of body weight relative to what is expected for healthy growth, reflecting a severe degree of overweight.

The use of 3 standard deviations serves as a critical threshold in pediatric growth assessments because it highlights individuals who are at higher risk for health complications associated with obesity. The WHO standards are designed to provide a comprehensive reference point for monitoring child growth, and the 3-standard-deviation marker specifically identifies those who are far beyond the norm, warranting closer health scrutiny and potential intervention.
