CDC Pediatric Growth Curves (Ages 2 to 20)
For children and teenagers, BMI is assessed using age-and-sex specific growth percentiles rather than rigid adult numbers.
Below expected pediatric velocity.
Ideal development envelope.

Clinical BMI Classification Matrix
Official World Health Organization (WHO) and Asian-Pacific criteria side-by-side comparison table.
| Classification | WHO Global BMI | Asian-Pacific BMI | Clinical Health Risk Level |
|---|---|---|---|
| ● Underweight | < 18.5 | < 18.5 | Nutritional deficiency, Osteoporosis risk |
| ● Normal (Healthy) | 18.5 – 24.9 | 18.5 – 22.9 | Lowest Epidemiological Disease Mortality |
| ● Overweight | 25.0 – 29.9 | 23.0 – 27.4 | Elevated risk: Hypertension, Pre-diabetes |
| ● Obesity | ≥ 30.0 | ≥ 27.5 | High Risk: CVD, Type 2 Diabetes, Sleep Apnea |
Clinical Health Risks & Medical Evidence
Peer-reviewed epidemiological risk factors associated with body mass deviations.
- Hypertension & Heart Disease: Visceral fat increases vascular resistance.
- Type 2 Diabetes: Excess fatty acids drive cellular insulin resistance.
- Sleep Apnea: Fat deposition in pharyngeal walls restricts airflow.
- Immune Impairment: Micronutrient deficits decrease WBC counts.
- Osteoporosis: Reduced estrogen and androgen synthesis degrades bone.
- Sarcopenia: Premature loss of skeletal muscle and strength.
