WHO GROWTH CHART &
TRIVANDRUM
DEVELOPMENT SCALE
DR. KRISHNA.D.S
GROWTH CHART
Growth charts are visible display of child’s physical growth
and development. Also called as “road-to-health" chart.
It was first designed by David Morley for growth assessment
and was later modified by WHO
NEED FOR ASSESSMENT
Child growth is monitored to:
Assess adequacy of nutrition
Identify weight status and potential for obesity
Screen for disease related to abnormal growth
HOW GROWTH IS ASSESSED??
• The assessment of growth may be longitudinal or cross sectional.
• Longitudinal assessment of growth entails measuring the same child
at regular intervals.
• Cross sectional comparisons involve large number of children of same
age.
• Basic growth assessment involves measuring a child’s weight and
length or height
HISTORY
• In 1940, data developed by Meredith at Iowa, used for growth
assessment.
• In 1960 and 1970, two other data sets were used, Harvard growth
curves and Tanner growth curves.
• In 1956 and 1965 ICMR undertook a nationwide cross sectional study
and established Indian reference charts.
HISTORY
• In 1977, National Centre for Health and Statistics along with CDC
developed growth curves based on Fel’s longitudinal study from 1929
to 1975.
• In 2000, CDC developed a growth curve based on data from national
health surveys and birth certificates in the U.S
BACKGROUND
In 1993 WHO undertook a comprehensive review of the uses and
interpretation of growth references
Did not adequately represent early childhood growth and that new
growth curves were necessary.
The World Health Assembly endorsed this recommendation in 1994.
In response WHO undertook the Multicentre Growth Reference Study
(MGRS) between 1997 and 2003 to generate new curves for assessing
the growth and development of children.
Who growth chart
MGRS
• MGRS combined a longitudinal follow-up from birth to 24 months
and a cross-sectional survey of children aged 18 to 71 months.
• Data gathered from 8440 healthy breastfed infants and young children
from diverse ethnic backgrounds and cultural settings
• Aim- healthy children living under conditions that favour the
achievement of their full genetic growth potential
Criteria for Inclusion
• Access to health care and breastfeeding support
• Full term birth
• No smoking during pregnancy
• Exclusive or primarily breastfeeding > 4 months
• Began feeding solids by 6 months
• Continued breastfeeding > 12 months
The WHO charts support the theory that optimal nutrition +
optimal environment + optimal care = optimal growth
regardless of time, place or ethnicity.
Indicators
• For the assessment WHO has provided charts for both boys and girls (age of
5yrs)
• Growth indicators are used to assess growth,
length/height-for-age
weight-for-age
weight-for-length/height
BMI (body mass index)-for-age
WHO GROWTH CHART
x-axis:
• In WHO Growth chart, x-axes show age. Points plotted on vertical
lines corresponding to completed age (in months, or years)
y-axis:
• y-axes show length/height, weight, or BMI. Points plotted on or
between horizontal lines corresponding to length/height, weight or
BMI as precisely as possible
WHO GROWTH CHART
• Growth curves are constructed using Box Cox Power Exponential
Method (BCPE) along with curve smoothing by cubic splines.

Cut off values……
• WHO growth standards are based on healthy children living in optimal
conditions so more extreme cutoffs are used to identify nutrition
risk.
• WHO charts use 2nd and 98th percentiles as the outermost percentile
cutoff values indicating abnormal growth.
• CDC use 5th and 95th percentile as cut off values.
Interpretation of growth curves
Suspect Risk,
• A child’s growth line crosses a z-score line.
• There is a sharp incline or decline in the child’s growth line.
• The child’s growth line remains flat (stagnant); i.e. there is no gain in
weight or length/height.
Normal growth curve runs parallel to the median curve.
In India….
• India has adopted the new WHO Child Growth Standards (2006) in
February 2009
• These standards are available for both boys and girls below 5 years of
age.
• WHO growth chart has been incorporated with "Mother and Child
Protection Card"

Management
• Weight b/w curves 1 & 3-undernourished,require supplementary
feeding at home
• Weight below curve 3 - consult the doctor and follow his advice.
• Weight below curve 4 - hospitalized for treatment
USES
• Growth monitoring
• Diagnostic tool
• Planning and policy making
• Educational tool
• Tool for action
• Evaluation
• Tool for teaching
TRIVANDRUM DEVELOPMENT SCALE
• Screening tool to test the development delay in children under the age
of 2 yrs
• Developed by Child Development Centre, SAT, Trivandrum
• 17 test items, selected by trial and error from Bayley’s Scale of Infant
Development (Baroda norms).
• Helps to screen motor, mental, hearing and visual development.
Who growth chart
How to use TDSC ??
• Left end of the horizontal line represents, the age at which 3% of
children passed the item and right end represents the age at which 97%
of the children passed that item.
• Vertical line is drawn from the chronological age
• Failure to achieve an item that falls short on the left hand side of
vertical line – developmental delay.
VALIDATION OF TDSC
• Done on the sample from coastal Neendakara Panchayath & Baby
Well clinic, SAT. (both in community and at hospital)
• Out of 1945 children screened 49 showed developmental delay.
• Denver Developmental Screening Test (DDST) was used as standard
for validation
TDSC has a sensitivity of 66.7% and specificity of 78.8%
Currently, used by Anganwadi workers in community field survey.
Can be interpreted by any person with minimal training.
Needs 5- 7 minutes
