Centile Assessment for a 12-Year-Old Boy

Height Assessment

A 12-14 year old boy with a height of 163.5 cm falls at approximately the 90th centile, according to the CDC/WHO growth charts, with the 90th centile value listed as 154.6 cm for 12-14 year olds, as recommended by the American Academy of Pediatrics 1
The height of 163.5 cm is significantly above the mean height of 141.4 cm for boys aged 12-14 years, indicating above-average height for age, based on data from the Centers for Disease Control and Prevention 1

The boy's weight of 49.1 kg places him between the 50th and 75th centiles for his age group, according to the American Heart Association 1, 2
For boys aged 12-14 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 upper-normal range, as stated by the American Academy of Pediatrics 1

The calculated BMI of 18.4 kg/m² falls within the normal range for a 12-year-old boy, between the 50th-75th centiles, according to the World Health Organization 3, 4
The normal BMI range for boys this age is approximately 16-21 kg/m², as recommended by the American Academy of Pediatrics 3, 4

The boy's height is significantly above average for his age group, suggesting he may be experiencing an early growth spurt or is constitutionally tall, based on guidelines from the American Heart Association 1, 2
The combination of height at the 90th centile and weight between the 50th-75th centile suggests a healthy growth pattern without evidence of overweight or underweight status, as stated by the American Academy of Pediatrics 1, 2

Growth charts may vary slightly between different populations and time periods, but the UK WHO charts represent the current standard for assessment, according to the Centers for Disease Control and Prevention 5
