Growth Centile Assessment for 14-Year-Old Girl
For a 14-year-old girl with weight 63.9 kg and height 168.5 cm, the height is approximately at the 75th-90th centile (indicating above-average height) and the weight is approximately at the 75th-85th centile on UK WHO growth charts, both representing normal, proportional growth. 1
Height Assessment
- The height of 168.5 cm places this girl well above the 50th centile, likely between the 75th and 90th centile for age, indicating she is taller than average for her age group. 1
- UK WHO growth charts for children aged 2-20 years should be used for this assessment, as WHO standards only extend to 59 months. 1
- This height is substantially above the predicted adult height for girls (approximately 165 cm with range 155-175 cm based on mid-parental height calculations), suggesting she may be near her final adult height or has tall genetic potential. 2
Weight Assessment
- The weight of 63.9 kg falls approximately at the 75th-85th centile for a 14-year-old girl, which is within the normal range but on the higher side of normal. 1
- This weight is proportional to her height, as she is also tall for her age, indicating balanced growth rather than excess adiposity. 1, 3
BMI Calculation and Interpretation
- Calculating BMI: 63.9 kg ÷ (1.685 m)² = 22.5 kg/m², which falls within the normal range (18.5-24.99 kg/m²) and is appropriate for her age and height. 1, 3
- The BMI of 22.5 kg/m² is well below the 95th centile threshold (approximately 28.2 kg/m² would indicate obesity at this age), confirming healthy weight status. 1
- The concordance between height and weight centiles (both in the 75th-90th centile range) indicates proportional, healthy growth without evidence of underweight or overweight status. 3
Clinical Monitoring Recommendations
- Serial measurements over time provide more valuable information than single measurements for assessing growth trajectory and velocity. 1, 3
- Continue regular growth monitoring every 6-12 months to ensure maintenance of appropriate growth trajectory, particularly as she approaches final adult height. 1, 3
- Plot measurements on growth charts to visualize the growth pattern over time and ensure she maintains her current growth channel. 3
- Consider parental heights when interpreting these measurements to account for genetic potential, as her above-average height may reflect familial tall stature. 3, 2
Key Clinical Considerations
- Both measurements falling between the 75th and 90th centiles suggest a healthy, proportional growth pattern without concerning deviations. 3
- Growth velocity is as important as absolute measurements; any significant deviation from her established growth channel would warrant further evaluation. 1, 2
- At 14 years, she is likely in mid-to-late puberty, and growth velocity should be assessed in context of pubertal stage. 1
