Centile Assessment for a 12-Year-Old Girl with Height 150.3 cm and Weight 42.25 kg
Based on the UK WHO growth charts, a 12-year-old girl with height of 150.3 cm and weight of 42.25 kg falls approximately between the 50th and 75th centiles for both height and weight.
Height Assessment
- The height of 150.3 cm for a 12-year-old girl places her between the 50th and 75th centiles according to the UK WHO growth charts 1
- This height indicates normal growth for age, suggesting appropriate linear growth progression 2
- For comparison, the average height for girls at this age ranges between approximately 147-152 cm, with 150.3 cm falling within the normal range 1
Weight Assessment
- The weight of 42.25 kg for a 12-year-old girl also falls between the 50th and 75th centiles on the UK WHO growth charts 1
- This weight is appropriate for her height, indicating a balanced growth pattern 3
- The normal weight range for girls this age is approximately 40-45 kg at the 50th centile, placing her weight in the normal range 1
BMI Assessment
- Calculating her BMI: 42.25 kg ÷ (1.503 m)² = 18.7 kg/m²
- This BMI falls within the normal range (between 18.5-24.99 kg/m²) for her age 4
- A BMI of 18.7 kg/m² for a 12-year-old girl indicates appropriate weight for height without evidence of underweight or overweight status 3
Clinical Interpretation
- The combination of height and weight both falling between the 50th and 75th centiles suggests a healthy, proportional growth pattern 1
- This growth pattern indicates adequate nutrition and normal development for a girl at this stage of puberty 5
- Girls with normal growth patterns at this age typically continue to grow for approximately 1-3 more years after menarche, which should be monitored during follow-up assessments 6
Important Considerations
- Growth velocity is as important as the absolute measurements; serial measurements over time provide more valuable information about growth patterns than single measurements 3
- Parental heights should be considered when interpreting growth charts to account for genetic potential 3
- The timing of puberty significantly impacts growth patterns in girls this age, with earlier puberty potentially leading to earlier growth plate closure 5, 7
Monitoring Recommendations
- Continue regular growth monitoring every 6-12 months to ensure maintenance of appropriate growth trajectory 3
- Plot measurements on growth charts to visualize the growth pattern over time 3
- Consider evaluating pubertal development stage as this significantly impacts growth velocity and final height potential 7
