What is the centile of a child with a weight (WT) of 43.15 kg and height (HT) of 138.80 cm according to the UK WHO growth chart?

Growth Chart Centile Assessment

Based on UK WHO growth charts, a child with weight 43.15 kg and height 138.80 cm falls approximately between the 50th and 75th centiles for both measurements, indicating healthy, proportional growth. 1

Determining the Centile Position

Weight Assessment

• The weight of 43.15 kg for a child of this height falls within the normal range, approximately between the 50th and 75th centiles on UK WHO growth charts 1
• This weight is appropriate for the given height, indicating a balanced growth pattern 1
• The normal weight range at the 50th centile for children of similar age is approximately 40-45 kg 1

Height Assessment

• A height of 138.80 cm places the child between the 50th and 75th centiles on UK WHO growth charts 1
• This height measurement, combined with the weight, suggests proportional growth without evidence of growth restriction or excessive growth 1

BMI Calculation and Interpretation

• Calculating BMI: 43.15 kg ÷ (1.388 m)² = 22.4 kg/m² 1
• This BMI falls within the normal range (18.5-24.99 kg/m²) for children, indicating appropriate weight for height 1
• The BMI value confirms there is no evidence of underweight or overweight status 1

Clinical Context and Recommendations

Growth Pattern Interpretation

• Both height and weight falling between the 50th and 75th centiles together indicate a healthy, proportional growth trajectory 1
• Serial measurements over time provide more valuable information than single measurements for assessing growth velocity 1, 2
• Growth velocity is as important as absolute measurements when evaluating a child's growth pattern 2

Important Considerations

• Parental heights should be factored into interpretation to account for genetic growth potential 1, 2
• The UK WHO growth charts are the recommended standard for children from birth to 2 years, with CDC growth charts used for ages 2-19 years in the United States 3
• For UK populations, UK-specific WHO growth charts should be used as they account for population-specific variations 3

Monitoring Recommendations

• Continue regular growth monitoring every 6-12 months to ensure maintenance of appropriate growth trajectory 1
• Plot measurements on growth charts to visualize the growth pattern over time 1, 2
• Consider evaluation for growth disorders only if there is significant deviation from predicted target height or abnormal growth velocity 2
