Growth Assessment for a 13-Year-Old Girl with Weight 74.95 kg and Height 163 cm

Based on UK WHO growth charts, a 13-year-old girl with a weight of 74.95 kg and height of 163 cm is above the 95th centile for weight and approximately at the 75th centile for height, indicating obesity.

Height Assessment

  • Height of 163 cm for a 13-year-old girl is between the 50th and 75th centile on UK WHO growth charts, indicating normal height for age 1
  • This height measurement suggests appropriate linear growth without evidence of growth abnormalities 2

Weight Assessment

  • Weight of 74.95 kg for a 13-year-old girl is significantly above the 95th centile (approximately 65-70 kg would be at the 95th centile) 1
  • The weight is substantially higher than the expected weight for a girl of this age and height 1

BMI Assessment

  • Calculating BMI: 74.95 kg ÷ (1.63 m)² = 28.2 kg/m²
  • This BMI value is above the 95th centile for a 13-year-old girl, indicating obesity 1, 3
  • BMI values above the 95th centile in adolescents are associated with increased risk of becoming overweight or obese adults 4, 5

Clinical Interpretation

  • The discrepancy between height and weight centiles (height at 75th centile, weight above 95th centile) indicates disproportionate weight gain relative to height 2
  • Adolescents with BMI values above the 95th centile have significantly increased body fat percentage, even with normal height 6
  • Excessive weight during adolescence is associated with increased risk of metabolic syndrome, insulin resistance, and cardiovascular disease in adulthood 4, 6

Monitoring and Management Considerations

  • Regular monitoring of growth parameters is essential to track changes in BMI over time 2
  • Adolescents with obesity benefit from comprehensive assessment of metabolic parameters (blood pressure, lipid profile, glucose metabolism) 6, 5
  • Early intervention is critical as adolescent obesity strongly predicts adult obesity 4, 5
  • Growth velocity and previous growth trajectory should be considered alongside current measurements for comprehensive assessment 2

Reference Considerations

  • UK WHO growth charts are the appropriate standard for assessing growth in UK children and adolescents 1, 7
  • The WHO growth standards reflect normal growth under optimal environmental conditions and can be used to assess children regardless of ethnicity or socioeconomic status 7
