GROWTH MONITORING
Dr Hemchand K PReviewed by
Dr Thangavelu S
Why should a paediatrician monitor growth of a child under his care?
• Barometer of well being in a given child. • Important pillar of preventive care. • Helps - reassure normalcy• Helps - identify growth disorders, nutritional
disorders & systemic diseases, early.
Khadilkar V, Khadilkar A. Growth charts: A diagnostic tool. Indian J Endocr Metab. 2011;15(Suppl 3):S166–71.
What is the difference between growth standard and reference?
Growth reference• Descriptive chart - from a
population which is believed to be growing under optimal health and nutrition.
• Eg: Old IAP charts
Growth standard• Prescriptive standard from a
population where - possible environmental & nutritional variables controlled
• Sole independent instrument upon which decisions are made
• Eg: WHO Standards from MGRS study
Vaman Khadilkar, Supriya Phanse. Growth charts from controversy to consensus. Indian J Endocrinol Metab 2012 Dec; 16 (Suppl 2): S185-S187
Why should all paediatricians use the same chart and cut-offs for interpretation?
10 year old boy with height of 124 cm
10 year old boy BMI 19.1 kg/sq m
IAP 3rd percentile 123.6 – NOT SHORT CDC – shortWHO 2007 – short
Khadilkar charts – short (< 124.3 cm)Marwah charts - short (< 125.4 cm)
CDC (20.4) – NormalIOTF using adult 25 kg/sq m – Normal
Marwah 85th percentile – NormalKhadilkar 75th percentile - Normal
K N Agarwal (18) – OverweightIOTF using adult 23 kg/sq m – Overweight
Marwah 85th percentile – OverweightWHO 2007 - Overweight
What are the anthropometric measures a paediatrician should record in his office practice?
IAP growth monitoring guidelines for paediatricians in 2007.
A - Note – even if the child < 2 years can stand – prefer to use the lengthKhadilkar V, Khadilkar A, Choudhury P, Agarwal A, Ugra D, Shah N. IAP Growth Monitoring Guidelines for Children from Birth to 18 Years. Indian Pediatr. 2007;44:187–97.

What growth charts should a paediatrician use in office practice?
Combined IAP – WHO charts from birth to 18 years (0-5 WHO and 5-18 IAP) are also made available for continuous growth monitoring
Onis M, Garza C, Onyango AW, Martorell R. WHO Child growth standards. Acta Pediatr. 2006;95(Suppl 450):S1–101.Khadilkar V, Yadav S, Agarwal KK, Tamboli S, ,Banerjee M, Cherian A et al. Revised IAP growth charts for height, weight and body mass index for 5- to 18-year-old Indian children. Indian Pediatr 2015; 52(1):47-55.
Age Chart recommended
< 5 years IAP modified WHO charts> 5 years IAP 2015 5-18 charts
Why has IAP made this recommendation?
WHO 2006 standards IAP 2015 references
Nature Prescriptive Prescriptive for BMI; descriptive
for other aspects of growth
Norm Breast feeding Good nutrition and health
Statistical methods LMS method of statistics LMS method of statistics
Exclusion of obese Yes Yes
IAP 2015 references – most recent, prescriptive for BMI, excludes obese, robust.Statistical tools – recommended by the IAP
WHO charts (IAP modified)
• Please enter the name and DOB• Single page – assesses – Height/ length, weight and
head circumference• Back side – Weight for height• ONLY 4 LINES (4 percentiles) – for convenience• Expressed both percentile and Z score• Vertically – 1 dark line – 15 days• Vertically – 1 light line – 1 week• Horizontally – 1 line represents 1 cm or 1 kg
15
16
How should a paediatrician plot on the growth chart?• Enter the name, date of birth on the chart. • Growth is marked with a dot (not circle or cross) at point of
intersection of measure (on the y-axis) and the chronological age (on x-axis).
• Each year is divided as 12 months – NOT DECIMAL AGE. • When you make subsequent measurements on same chart,
join the points by a line. • Remind the parents of the next growth measurement and
explain your findings to them and reassure them.
Khadilkar V, Khadilkar A, Choudhury P, Agarwal A, Ugra D, Shah N. IAP Growth Monitoring Guidelines for Children from Birth to 18 Years. Indian Pediatr. 2007;44:187–97.
How To Adjust For The Family Size?
• Target Height also known as the adjusted mid parental height is calculated as follows:
• Boy: (MHT+FHT+13)/2• Girl: (MHT+FHT-13)/2• This height is plotted at 18 years of age on the chart• Target range is 6 cms below and above the target
height
How are the new charts more user friendly and parent friendly?• The IAP modified WHO charts allows one to plot –
weight, height and head circumference on a single page and at convenient 15 day intervals.
• The weight, height (0-18) and BMI (5-18) measurements can be plotted at 6 monthly intervals on the 0-18 year charts.
• The BMI and weight for height charts in 0-18 charts and 0-5 charts are colour coded – red colour indicating obesity.

How to recognise abnormal growth?
Height < 3rd percentile - stunting
Weight < 3rd percentile – NO INTERPRETATION
Weight for height < 3rd percentile - wasting
Weight for Height < 0.1st percentile – severe wasting

1 year period (older child)
What should a paediatrician do in case of recognition of abnormal growth?• Check the accuracy measurement/ plotting• Look at the trend of deviation (a single cross
sectional measure has limitations - growth does not always follow a smooth curve)
• A line is drawn from the plotted point to the 50th percentile and vertically downwards to touch the x- axis
• This is the corresponding height age (HA) & weight age (WA)
• CA (chronological age) = HA = WA – in a normal child
CA > HA > WA – has nutritional deprivation or systemic disease
CA > WA > HA – has endocrine disease
WA > HA > CA – has nutritional obesity
WA > CA > HA – has endocrine obesity
HA > WA > CA – has precocious puberty
Abnormal growth Interpretation Disorder
CA = HA = WA
CA > HA > WA
CA > WA > HA
WA > HA > CA
WA > CA > HA

Summary of interpretation of abnormal growth
What is the role of bone age in growth assessment?
• Bone age complements growth assessment. • Speaks of the growth potential of a given child. • Bone age should be assessed using the Tanner
whitehouse method or a Greulich pyle atlas.• Bone age is plotted at the point of intersection of
current height (y-axis) and bone age (x-axis).

How should a paediatrician assess the growth of a LBW preterm baby?
The growth curves for preterm babies have been developed similar to the WHO 2007 standards – intergrowth 21st post natal standards. These standards must be used in preterm babies will they reach term gestational age. Downloadable from: https://intergrowth21.tghn.org/articles/

Miscellaneous tit bits
• All girls must have their growth plotted on pink chart and boys on the blue chart. Plotting growth on the chart for opposite sex is unacceptable.
• Weight should not be measured more than once in 15 days and 30 days – during and beyond infancy, respectively. This is to avoid unnecessary anxiety.
• It is preferred to interpret weight in conjunction with height and not in an isolated perspective.
• Practical difficulty exists in plotting children < 5 years on 0-18 charts
Miscellaneous tit bits• Crossing two major percentiles in 6 months and 1 year is pathological
in infancy and childhood.
• The growth charts committee recommends Weight for height to diagnose wasting and obesity in the under 5 age group.
• The term Severe Acute Malnutrition (SAM) was defined by WHO for health workers based on Weight for Height Z-score <-3 - should be used beyond 6 months.
• Percentiles and Z-scores are interchangeable. For uniformity and ease, percentiles are preferable
• IAP growth charts app (for android phones) available for growth monitoring of Indian children
