Growth Chart Assessment for 11-Year-Old Boy
Centile Rankings
Based on the provided measurements (weight 42.8 kg, height 132.60 cm), this 11-year-old boy falls at approximately the 50th-75th centile for weight and below the 25th centile for height on UK WHO growth charts. 1
Weight Assessment
- The weight of 42.8 kg places this boy between the 50th and 75th centiles for his age group 1
- For boys aged 11-12 years, the 50th centile weight is approximately 42-45 kg, while the 75th centile is around 49-50 kg, placing this boy's weight in the normal range 1
Height Assessment
- The height of 132.60 cm is below average for an 11-year-old boy 1
- For comparison, boys aged 12-14 years have a mean height of 141.4 cm and a 90th centile value of 154.6 cm 1
- This height measurement suggests the child is tracking below the 25th centile, which warrants attention 2
Clinical Implications
The discrepancy between weight centile (50th-75th) and height centile (below 25th) requires clinical evaluation to assess growth velocity and rule out underlying conditions. 2
Recommended Actions
- Plot serial measurements every 3-6 months on appropriate UK WHO growth charts to track growth velocity and trajectory 2
- Growth velocity over time using multiple data points is more informative than a single measurement 2
- Evaluate family growth patterns to assess genetic contribution to the child's stature 2
- Consider comprehensive medical evaluation if height remains below the 2nd percentile, as this may indicate chronic malnutrition, underlying medical conditions, or genetic factors 2
Important Considerations
- The UK has adopted WHO growth standards, with CDC growth charts recommended for older children 2
- Values 2 standard deviations below the median (2.3rd percentile, labeled as 2nd percentile) are used to identify children whose growth might indicate adverse health conditions 2
- Screening for chronic conditions affecting growth (celiac disease, inflammatory bowel disease) and endocrine disorders should be considered if growth faltering is documented 2
