Food for thought
 Highest growth velocity seen at ?
 Difference between failure to thrive and short stature ?
 What is growth failure ?
 What is the most important determinant for
Birth weight?
Weight at 2 years ?
Final adult weight ?
 What is MPH and what does it signify
WHAT IS GROWTH?
 Growth is the sum of all cell replication and organ differenciation
processes in the body.
 • Dynamic process
 • Increase in the physical size of the body
 • Growth is genetically predetermined.
 • Growth progresses orderly with individual variation.
 • Factors influencing growth and development
 Nutrition Family Emotional factors Socio cultural and community
Physical factors
 Growth is an indicator of physical and mental well being of a child.
Growth and development
 .
Growth Development
Net increase in the size or mass of
tissues
Specifies maturation of functions
Multiplication of cells
Increase in intracellular substance
Hypertrophy and expansion of cell
size
Maturation and myelination of
nervous system
Indicates acquisition of skills
Laws of growth
 Growth and development of children is a continuous and orderly
process
 Growth pattern of every individual is unique
Order of growth is cephalocaudal and distal to proximal (head
neckarms legs and hands increase in size before arms )
 Different tissues grow at different rates
Factors affecting growth
Fetal growth
 Maternal factors : maternal malnutrition, comorbidities, age,
obstetric complications, parity, acquired infections
 Placental factors
 Teratogens
 Fetal growth factors
 Fetal hormones
 Sex : males > females
 Genetic potential
Factors affecting growth
 Size at birth does not affect the infants genetic growth potential, in
the first 2 years of life that infants gradually transition from their birth
size to their own genetically determined height potential.
 Infants shift linear growth percentiles; 65% infants exhibit such shifts –
moving up and down the growth charts. By 24 months these shifts
are complete and children have entered a specific growth channel
 Birth weight is generally a poor indicator of the eventual growth
pattern (except IUGR), most show catch up growth
Factors affecting growth
Post natal period
 Genetic factors
 IUGR
 Nutrition
 Hormonal influences : GH, Thyroid, Gonadal steroids, Glucocorticoids
 Sex
 Infections
 Chemical agents
 Trauma
 Socioeconomic factors
 Ethnicity and race
 Environment and stimulation
 Secular trend
PURPOSE OF GROWTH ASSESMENT
 The purpose is to determine whether child is growing “normally”
or
 Has “growth problem ” or trend towards a growth problem that
should be addressed.
ASSESSMENT OF GROWTH
 The assessment of growth may be longitudinal or cross sectional.
 Longitudinal assessment involve measuring the same child at regular
intervals.
 Cross sectional comparison involve measuring large number of children
of same age.
 Basic growth assessment involves
 Measuring child’s weight and length or height.
 Comparing these measurements to growth standards.
When to assess normal growth
WELLNESS VISITS
 Immunization contacts : 6, 10, 14 weeks, 9 months, 15- 18 months
 Additional monitoring at 6 monthly intervals with opportunistic
monitoring at illness visits is recommended.
 4 to 8 years: height and weight 6 monthly and BMI, PL, SMR yearly
from 6 years
 9 to 18 years: height, weight, BMI, SMR should be assessed yearly
Red flag signs/ criteria for referral
 Height <3rd
or >97th
 HC <3rd
or >97th
 Crossing 2 major percentile lines
 Below or above MPH range
 Absence of weight gain from 2 to 3 months between 6 to 11 months
 BMI > 23rd
adult equivalent of IAP
 Growth velocity less than 5cm/year between 3 to 9 years
 Girls with axillary, pubic hair growth or breast budding before 8 years and
boys with axillary, pubic hair growth or genital growth or testicular
enlargement before 9 years
Red flag signs/ criteria for referral
 Delayed puberty: girls without breast budding by 14yrs & no
menarche by 15 yrs or boys with no signs of puberty till 16 yrs
 Arrest of puberty at some stage >2yrs
 Micropenis
 b/l or u/l undecended testis
 Atypical genitalia
 u/l or b/l gynecomastia in boys
 Hirsutism or menstrual irregularities in girls
WHAT ARE GROWTH CHARTS?
 Visible display of child’s physical growth and development.
 • “Road-to-health" charts.
 • First designed by David Morley, later modified by WHO.
 These growth charts are primarily designed for longitudinal follow-up
of a child(growth monitoring),to interpret the changes over time.
BASICS OF GROWTH CHARTS
 Growth chart is
characterized by
various curves, each
representing specific
percentile/ SD.
 • Percentile curves
represent frequency
distribution curves.
 • Proportion charts use
Z score lines
Z- SCORE OR STANDARD DEVIATION
SCORE
 It represents the deviation of the value for an individual from the
median value of the reference population
(Observed value) - (Median reference value)
 Z score = ------------------------------------------------------------------------
Standard deviation of reference population
 A fixed Z score interval implies a fixed height or weight difference for
children of a given age .
 Advantage:- Allows mean and SD calculation for a group of Z score
in population based applications
PERCENTILE
 The rank position of an individual on a given reference distribution,
stated in terms of what percentage of the group the individual
equals or exceeds .
 Unable to calculate summary statistics with the use of percentiles.
 Towards extremes of the reference distribution-only little change in
percentile value with substantial change in weight or height status

TYPES OF GROWTH CHARTS
 Reference growth charts –
 These charts are descriptive and shows how children grow.
 Health status of the reference population is not taken into consideration.
 Standard growth charts-
 Prescriptive- shows how children should grow.
 Reference population is selected on health grounds

HISTORY OF INNOVATION OF
GROWTH CHARTS
Published the first growth charts
in his work “Histoire Naturelle”
GROWTH CHARTS EVOLUTION
 Since early 1900s variety of growth references were developed and
used.
 Limitations : Infants and preschool children not covered properly
Limited representation of ethnic, genetic, socioeconomic variability
 Stuart/Meredith growth charts (1946-1976)
 Parameters Measured: stature and weight
 Population: White children living near Iowa city, Iowa, Boston,
Massachusetts, from 1930 to 1945.
 Limitations: Sample size were small/didn’t represent standard US
population Percentile curves smoothened by hand Statistical curve
fitting procedures were not used
TANNER GROWTH CHARTS
 In 1965 Tanner, Whitehouse
and Takaishi made growth
standards from birth to
maturity in British children
 Growth charts made for
height, weight, height
velocity and weight velocity
(Birth to 19 years).
 In 1973, Tanner and
Whitehouse introduced new
charts by enlarging birth to 5
years section of the previous
weight and height charts •
The new charts have
enough space for accurate
and repeated plotting in the
first two years after birth
TANNER GROWTH CHARTS
NCHS GROWTH CURVES 1977
 National Academy of Sciences urged to develop new growth
charts for infants and children by using current data.
 NCHS task force of experts was formed
 Developed mainly to assess nutritional disturbances in U.S. children
 Source of data: Fels Research Institute Health Examination Surveys of
NCHS
Disadvantages
 Triplets were excluded from study
 Twins and low birth weight not excluded
 National survey data were not available for birth to one year age
group; Supplemented with Fels data.
 The infant charts were solely based on the Fels data
1977 NCHS GROWTH CHARTS
 Weight for age Birth to 36
months 2 to 18 years
 Length for age Birth to 36
month
 Weight for Length Birth to 36
months Boys(49 to 103 cm)
Girls(49 to 101cm)
 Head Circumference for age
Birth to 36 months
 Stature for age 2 to 18 years
 Weight for stature Boys(90 to
145 cm) Girls(90 to 137 cm)
CDC GROWTH CHARTS 2000
 NCHS growth charts in use since 1977 were revised.
 As CDC Growth Charts: released in 2000
 Recommended for use in clinical practice and research to assess size
and growth in U.S. children.
 Two set of charts Infants, birth to 36 months of age Children and
adolescents from ages 2 to 20 years.
 New body mass index-for-age (BMI-for-age) charts were created
CDC GROWTH CHARTS
2000
 Data collected: National Health
Examination Surveys II, III
National Health And Nutritional
Examination Surveys I,II&III and
Supplemental data
CDC GROWTH CHARTS
2000
 Exclusions:
 ▪ Data for all VLBW
infants were excluded
from infant growth
charts
 ▪ Excludes data from
NHANES III for ages >6
years
 ▪ Data from NHANES III
for ages
CDC BMI charts
WHO GROWTH CHARTS 2006
 NCHS/WHO growth reference, did not adequately represent
early childhood growth and that new growth curves were
necessary.
 World Health Assembly endorsed this recommendation in 1994.
 WHO undertook the Multicentre Growth Reference Study (MGRS)
between 1997 and 2003 to generate new curves for assessing the
growth and development of children UNDER THE AGE OF 5 YEARS
OVER THE WORLD
 The MGRS combined a longitudinal follow-up
from birth to 24 months & a cross-sectional survey
of children aged 18 to 71 months.
 Sample Size: 8440 healthy breastfed infants and
young children 1743 for longitudinal component
6697 for cross sectional component Study
Location Brazil, Ghana, India, Norway, Oman
and USA.
 The study populations lived in
• Socioeconomic conditions favourable to growth
• Mobility was low
• ≥20% of mothers followed WHO feeding
recommendations and
• Breastfeeding support was available
The mothers were non smokers and breast feeding
their children
 Why MGRS is unique? – Growth standards produced by selecting
healthy children living under conditions likely to favour achievement
of their full genetic growth potential.
MGRS data included
 Weight and head circumference at all ages,
 Recumbent length (longitudinal component),
 Height (cross-sectional component),
 Length and Height (between 18 to 30 months)
 Arm circumference, triceps and subscapular skinfold thickness (all
children aged ≥3 months)
SALIENT FINDINGS IN MGRS
 Striking similarity in linear growth across the diverse populations were
studied.
 An evaluation of the differences in length of participants from birth
to 2 yrs of age within and among the MGRS sites demonstrated 70%
of the total variance in length was due to inter individual differences
and only 3% was due to inter site differences
 Greater genetic variability resides within populations than among
populations
WHO GROWTH CHARTS
 Charts developed
• Weight for age
• Length/height for age
• Weight for length
• Weight for height
• Body Mass Index for age
• Mid arm circumference for age
• Head circumference for age • Triceps skin fold thickness for age • Sub
scapular skin fold thickness for age • Growth velocity charts based on weight,
height and head circumference • Windows of achievement in motor milestones
WHO growth standards were produced with both Z score curves and percentile
curves
Weight for age
 Age dependent factors
Weight for age
Length/height for age
 Age dependent
Height for age
Weight for length / height boys
 Age independent factors
BMI for age
 Age independent factors
BMI for age
 Age independent factors
Head circumference for age
 Age dependent factors
Mid arm circumference for age
 Age independent factors
Subscapular skinfold
 BMI is not a direct measurement
of body fat
 Skinfold thickness indicates the
status of fat deposits in the
body.
 Measured using Harpenden
calliper
 Measured over the triceps,
subscapular, biceps and
suprailiac area.
Triceps skinfold for age
 Normal skinfold thickness
depends on age and sex
 Females > males
 >85th
centile in age specific
percentile charts are
abnormal
FEATURES OF WHO GROWTH
CHARTS
 Based on prescriptive approach
 Breastfeeding the biological “norm” and establishes the breastfed
infant as the normative growth model
 Provides a truly international standard, that child populations grow
similarly across the world’s major regions when their needs for health
and care are met
 New innovative growth indicators: the skin fold thicknesses
 Accompanying windows of achievement for six key motor
development milestones provides a unique link between physical
growth and motor development.
AGARWAL GROWTH CHARTS 1992
& 1994
 Before Agarwal growth charts, there were
not much nation wide studies to assess
growth of Indian children.
 Agarwal et al., conducted two separate
studies (published in 1992 and 1994) to assess
the growth performance of Indian children
aged birth to 18 years of age
 Developed Growth Charts for 2 age groups:
Birth to 6 years and 5 to 18 years
 50th
percentile of height of Indian children
from high socioeconomic groups
corresponded to 30th
– 40 th centiles in CDC
charts.
 50th
centile of adult stature corresponded to
the 10th
– 20th
centile in CDC charts
 BIRTH TO 6 YEARS
 Longitudinal study
 Children belonging to the affluent
population segments (urban) in seven
cities were selected: Bangalore,
Bombay, Calcutta, Delhi, Kota,
Ludhiana, and Varanasi.
 Years of Data collection: Two years
(1985-1987) as two different cohorts.
Cohort- I - birth to one year Cohort-II -
one to six years of age.
 Sample size: Cohort-I - 418 boys and 332
girls Cohort –II - 1011 boys and 874 girls
 Parameters measured: Weight
Height/length Circumferences of head,
chest and mid arm.
5 TO 18 YEARS
 Crosssectional study Study location: Data were collected from 23
schools North Zone(Delhi, Shimla, Dehradun and Nainital) West-
South Zone(Bombay, Madras and Udaipur) Central Zone(Lucknow,
Allahabad, Varanasi) East Zone(Dhanbad and Calcutta)
 Sample size: 12899 boys and 9951 girls studying in 1 to 12th std.
 Exclusion: Children with systemic diseases or with major surgeries
 Parameters measured: Weight Height, sitting height, Head and
Chest circumference Biacromial and Bicristal diameters and Skinfold
thickness (methods described by Tanner and Weiner and Lourie).
Sexual growth(development of genitalia, breast, presence of
auxillary and pubic hair(Graded according to Tanner)
KHADILKAR GROWTH CHARTS 2009
 WHO recommends that each country should update its growth
references every decade
 New growth references were produced in 2009 by Khadilkar et al.
 Selection of sites: The IAP divides India into five zones Ten cities were
selected from these zones Schools admitting children of
socioeconomically well off families were selected (11 schools)
NEW IAP GROWTH CHARTS 2015
 The need to revise IAP growth charts for 5- to 18-year-old Indian
children and adolescents was felt as India is in nutrition transition
and Previous IAP charts are based on data of two decades old.
 Studies performed on Indian children’s growth, nutritional
assessment and anthropometry from upper and middle
socioeconomic classes in last 10 years were identified
 Sample size: 87022 (5 to 18 years) • Data from 14 cities (Agartala,
Ahmadabad, Chandigarh, Chennai, Delhi, Hyderabad, Kochi,
Kolkata, Madurai, Mumbai, Mysore, Pune, Raipur and Surat) in India
were collected.
 They found small increases in height in 50th
and 97th
centiles and
striking differences in weight percentiles, inidicating secular trend
and epidemic of obesity
SECULAR TREND IN WEIGHT
SECULAR TREND IN HEIGHT
Paediatrician friendly growth charts
 User-friendly growth charts for
Paediatrician’s everyday use.
 No calculations are involved while using
these charts, neither for BMI nor for MPH
 MPH percentile lookup tool which was
designed in such a way that by joining
the father’s height on left to the mother’s
height on the right (both in CM) gives the
MPH percentile (on the middle line) for
that specific gender
 A quick BMI screening tool based on
weight for height that eliminates the need
to calculate BMI will help to rapidly
decide if a child is overweight, obese,
normal or underweight.
 In a busy clinic, less calculations the
pediatrician must perform the better.
Paediatrician friendly growth charts
Paediatrician friendly
growth charts
For ex: fathers height 178cm, mothers hight is 160cm
MPH
Growth velocity
Conclusion regarding growth
velocity should be drawn after a
minimum of 6 months of observation
Preferably after a year.
Growth occurs at different stages.
Growth velocity
 Period of rapid growth: intrauterine
 Postnatal growth, highest in the postnatal period, gradually
decreases upto the pre pubertal period followed by pubertal
growth spurt.
Girls Boys
Pubertal growth spurt Early , 10-11years Later, 9-14 years
Peak growth velocity 8-9cm/year 10.3cm /year
After menarche
growth velocity
declines and stops 2
years after menarche.
Higher peak growth
velocity and longer
period of growth
results in taller stature
Height velocity in Indian children
 Height velocity percentiles as per age for Indian children and adolescents for 5-17 years
 The peak median height velocities were 6.6 cm at 10.5 years in girls and 6.8 cm at 13.5
years in boys
 Aim: assess height velocity and develop height velocity percentiles in 5-17-year-old
apparently healthy Indian children from two centers from India (Pune and Delhi), and (ii)
to study the magnitude and
age at peak height velocity
during adolescence in
Indian children.
Upper segment and lower segment
ratio
 The trunk is relatively longer than LS
at birth ; US:LS = 1.7
 In postnatal life, the growth
velocity of LS is greater.
 1.3 at 3 years
 1 at 7 years
 0.89 during puberty
 Rises to slightly below 1
US : LS ratio growth charts - Indian
How to plot mid parental height
 Mid parental height is necessary to understand child’s genetic
potential so that child’s current height percentile can be checked
against MPH percentile.
 Involves a calculation and plotting at 18 years to know the mid
parental percentile
 MPH = (fathers heigh + mothers height)/ 2 +/- 6.5
 This value is plotted on charts, and gives an idea estimate of target
height for the child and the percentile it is likely to follow
 Projected adult height = MPH +/- 8.5cm
How to plot mid parental height
 For ex:
Fathers height 176cm
Mothers height 168cm
MPH = (176 + 168)/2 +6.5
= 178.5 
Present height
9 years: 126cm 
HA BA CA WA !!!???
 Bone age is a measure of the degree of skeletal maturity of a child, i.e.
how far the child has advanced in its development of the skeleton.
 Chronological age : it is the age of the child at present
 Height age : Height age is that age at which the childs present
height would have been appropriate for age OR the age that
corresponds to the childs height when plotted at the 50th
percentile
on a growth chart
 Weight age: the age that corresponds to the childs weight when
plotted at the 50th
percentile on a growth chart
How to plot height age
 For ex:
8 year old girls height is 140cm
Which corresponds to 10.5 years
Familial short stature BA = CA > HA
Constitutional delay of growth BA < CA and BA = HA
A: constitutional delay of growth and adolescence
BA < CA and BA = HA
B : Familial short stature
BA = CA > HA
C : Acquired pathogenic growth failure
BA < HA < CA
D Precocius puberty
BA > HA > CA

To remember

Neonatal growth charts
 Optimal post natal growth
 Growth standards versus
references
 Intrauterine and Postnatal
preterm growth charts
 Customized growth charts
 Correlation of growth charts
with outcomes
WHY DO WE NEED NEONATAL
GROWTH CHARTS?
 To identify SGA and LGA babies
 To monitor the growth over a period of time ( reflects illness and
nutritional status)
 To identify babies with EUGR at 36 weeks gestation
( neurodevelopmental impairment, final short height)
SGA- Asphyxia, hypothermia, hypoglycemia,
hypocalcemia, polycythemia, sepsis, death
LGA- Birth trauma, Asphyxia, hypoglycemia,
hypocalcemia, polycythemia

PRETERM GROWTH CHARTS
 Babson and Benda published fetal-
infant growth graph in 1976
 An extended intrauterine growth chart
Widely used in NICUs before 2003
 Limitations:
✓ X axis begins at 26 weeks – Not able to
plot younger preterm infants
✓ Y axis made in 500 gram increments –
Difficult to plot precisely
✓ Sample size very small – only 45 infants.
✓ Data 15 years old at the time of
publication
The dotted line is Babson and Benda 1976 growth chart
REVISED FENTON GROWTH CHARTS
2013
 In 2003, Fenton produced updated version of Babson and Benda charts.
 In 2013, revision of 2003 charts was done by Fenton and Kim.
 Aim to harmonize the preterm growth chart with the new WHO growth Standard
Features of revised charts:
✓ Based on the recommended growth goal for preterm infants, fetus and term infant.
✓ Sex specific charts.
✓ Equivalent to WHO charts at 50 weeks gestational age( 10 weeks post term age)
✓ Large sample size of 4 million preterm infants
✓ Recent population based surveys collected between 1991 to 2007
✓ Data from developed countries
✓ Enables plotting as infants are measured, not as completed weeks
✓ Exact Z score and percentile calculator available.
✓ Growth references not standards
INTERGROWTH- 21 CHARTS (2015)
 Series of projects
conducted
following the
WHO prescriptive

INTERGROWTH- 21 CHARTS (2015)
 Inter growth charts
SIZE -AT - BIRTH CHARTS
POST NATAL FOLLOW UP
CHARTS
POSTNATAL GROWTH
 *POSTNATAL DIP in weight- attributed to extracellular
fluid losses.
 *Most preterm also do not grow in length or head
circumference in the first week of life, so all 3 growth
parameters often cross percentiles downwards on
growth charts.
 *Grow approximately parallel to growth chart curves
once adequate nutrition is established and morbidities
addressed
Depends on genetic potential, internal and external factors
 Infancy (Nutrition)
 Childhood (Growth hormones)
 Puberty (Growth hormones + Sex Steroids)
APPROPRIATE PATTERNS OF POSTNATAL GROWTH
AGA with normal growth pattern AGA with EUGR
AGA with upward crossing due to
genetic potential after IUGR
LGA with good growth
due to genetic potential
LGA returning to normal growth
(infant of diabetic mother)
SGA with growth parallel to curve SGA regaining birth weight centile
TYPES OF FOETAL AND NEONATAL
GROWTH CHARTS
 Foetal growth charts-Foetal anthropometry estimation curves based
on USG measurements
 Birth Weight for Gestational Age Charts
 Neonatal growth charts
 1. Postnatal longitudinal growth charts for preterm infants
 2. Postnatal growth charts for infants born at term
Fetal growth charts
WHAT ARE CUSTOMIZED GROWTH
CHARTS?
 Adjusted to reflect maternal constitutional variation.
 Optimized, by presenting a standard free from pathological factors
such as diabetes and smoking; and
 Based on fetal weight curves derived from normal pregnancies,
rather than neonatal weight curves which include pathological
preterm deliveries.
Intra uterine growth charts
SPECIAL GROWTH CHARTS
 Down syndrome
 Turner syndrome
 Achondroplasia
 William syndrome
 Cerebral palsy
CDC DSGS GROWTH CHARTS
 Children with Down syndrome
have a different growth pattern
compared to other children
 The Down Syndrome Growing Up
Study (DSGS) enrolled a
convenience sample of children
with DS up to 20 years of age
and followed them
longitudinally.
 When compared to previous U.S.
growth charts for children with
Down syndrome There are clear
improvements in weight gain
during the first three years of life.
Males (aged 2-20 years) are

Uses of growth chart
1.Growth monitoring
2. Diagnostic tool: for identifying "high-risk“ children.
For example, malnutrition can be detected long before signs and symptoms of it
become apparent
3. Planning and policy making: by grading malnutrition, it provides an objective basis
for planning and policy making in relation to child health care at the local and
central levels
4. Educational tool: because of its visual character, the mother can be educated in
the care of her own child· and encourage her to participate more actively in
growth monitoring
Uses of growth chart
5. Tool for action: it helps the health worker on the type of intervention that is
needed; it will help to make referrals easier
6. Evaluation: it provides a good method to evaluate the effectiveness of
corrective measures and the impact of a programme or of special
interventions for improving child growth and development.
7. Tool for teaching: it can also be used for teaching, for example, the
importance of adequate feeding; the deleterious effects of diarrhoea.
8.Reassurance:It provides reassurance about child’s health and prevents
parental anxiety.
Answers
 Highest growth velocity seen at ?
Prenatal 66cm/yr > postnatal 25cm/yr
 Difference between failure to thrive and short stature ?
FTT- poor wt gain in infants and young children and
Short stature – subnormal linear growth in childhood and adolescence
 What is growth failure ?
Subnormal rate of growth; sustained height velocity <25th
centile or <-1.5SD
 What is the most important determinant for
Birth weight? – maternal and placental factors
Weight at 2 years ? – gradual transition from birth size to genetic potential
Final adult weight ? – genetic potential
 What is MPH and what does it signify – avg of both parents height after
correcting for sex, childs genetic potential
Take home points
 We must get into the habit of regularly plotting these
anthropometric data on the appropriate growth chart until the age
of 18 years, and this will help in picking up the reason for failure to
thrive early and thereby help to reduce expensive investigations.

    Factors affecting growth Fetalgrowth  Maternal factors : maternal malnutrition, comorbidities, age, obstetric complications, parity, acquired infections  Placental factors  Teratogens  Fetal growth factors  Fetal hormones  Sex : males > females  Genetic potential
  • 8.
    Factors affecting growth Size at birth does not affect the infants genetic growth potential, in the first 2 years of life that infants gradually transition from their birth size to their own genetically determined height potential.  Infants shift linear growth percentiles; 65% infants exhibit such shifts – moving up and down the growth charts. By 24 months these shifts are complete and children have entered a specific growth channel  Birth weight is generally a poor indicator of the eventual growth pattern (except IUGR), most show catch up growth

    PURPOSE OF GROWTHASSESMENT  The purpose is to determine whether child is growing “normally” or  Has “growth problem ” or trend towards a growth problem that should be addressed.
  • 12.
    ASSESSMENT OF GROWTH The assessment of growth may be longitudinal or cross sectional.  Longitudinal assessment involve measuring the same child at regular intervals.  Cross sectional comparison involve measuring large number of children of same age.  Basic growth assessment involves  Measuring child’s weight and length or height.  Comparing these measurements to growth standards.
  • 13.
    When to assessnormal growth WELLNESS VISITS  Immunization contacts : 6, 10, 14 weeks, 9 months, 15- 18 months  Additional monitoring at 6 monthly intervals with opportunistic monitoring at illness visits is recommended.  4 to 8 years: height and weight 6 monthly and BMI, PL, SMR yearly from 6 years  9 to 18 years: height, weight, BMI, SMR should be assessed yearly
  • 14.
    Red flag signs/criteria for referral  Height <3rd or >97th  HC <3rd or >97th  Crossing 2 major percentile lines  Below or above MPH range  Absence of weight gain from 2 to 3 months between 6 to 11 months  BMI > 23rd adult equivalent of IAP  Growth velocity less than 5cm/year between 3 to 9 years  Girls with axillary, pubic hair growth or breast budding before 8 years and boys with axillary, pubic hair growth or genital growth or testicular enlargement before 9 years

    WHAT ARE GROWTHCHARTS?  Visible display of child’s physical growth and development.  • “Road-to-health" charts.  • First designed by David Morley, later modified by WHO.  These growth charts are primarily designed for longitudinal follow-up of a child(growth monitoring),to interpret the changes over time.
  • 17.
    BASICS OF GROWTHCHARTS  Growth chart is characterized by various curves, each representing specific percentile/ SD.  • Percentile curves represent frequency distribution curves.  • Proportion charts use Z score lines
  • 18.
    Z- SCORE ORSTANDARD DEVIATION SCORE  It represents the deviation of the value for an individual from the median value of the reference population (Observed value) - (Median reference value)  Z score = ------------------------------------------------------------------------ Standard deviation of reference population  A fixed Z score interval implies a fixed height or weight difference for children of a given age .  Advantage:- Allows mean and SD calculation for a group of Z score in population based applications
  • 20.
    PERCENTILE  The rankposition of an individual on a given reference distribution, stated in terms of what percentage of the group the individual equals or exceeds .  Unable to calculate summary statistics with the use of percentiles.  Towards extremes of the reference distribution-only little change in percentile value with substantial change in weight or height status

    HISTORY OF INNOVATIONOF GROWTH CHARTS Published the first growth charts in his work “Histoire Naturelle”
  • 28.
    GROWTH CHARTS EVOLUTION Since early 1900s variety of growth references were developed and used.  Limitations : Infants and preschool children not covered properly Limited representation of ethnic, genetic, socioeconomic variability  Stuart/Meredith growth charts (1946-1976)  Parameters Measured: stature and weight  Population: White children living near Iowa city, Iowa, Boston, Massachusetts, from 1930 to 1945.  Limitations: Sample size were small/didn’t represent standard US population Percentile curves smoothened by hand Statistical curve fitting procedures were not used
  • 29.
    TANNER GROWTH CHARTS In 1965 Tanner, Whitehouse and Takaishi made growth standards from birth to maturity in British children  Growth charts made for height, weight, height velocity and weight velocity (Birth to 19 years).  In 1973, Tanner and Whitehouse introduced new charts by enlarging birth to 5 years section of the previous weight and height charts • The new charts have enough space for accurate and repeated plotting in the first two years after birth
  • 30.
  • 31.
    NCHS GROWTH CURVES1977  National Academy of Sciences urged to develop new growth charts for infants and children by using current data.  NCHS task force of experts was formed  Developed mainly to assess nutritional disturbances in U.S. children  Source of data: Fels Research Institute Health Examination Surveys of NCHS Disadvantages  Triplets were excluded from study  Twins and low birth weight not excluded  National survey data were not available for birth to one year age group; Supplemented with Fels data.  The infant charts were solely based on the Fels data

    WHO GROWTH CHARTS2006  NCHS/WHO growth reference, did not adequately represent early childhood growth and that new growth curves were necessary.  World Health Assembly endorsed this recommendation in 1994.  WHO undertook the Multicentre Growth Reference Study (MGRS) between 1997 and 2003 to generate new curves for assessing the growth and development of children UNDER THE AGE OF 5 YEARS OVER THE WORLD
  • 39.
     The MGRScombined a longitudinal follow-up from birth to 24 months & a cross-sectional survey of children aged 18 to 71 months.  Sample Size: 8440 healthy breastfed infants and young children 1743 for longitudinal component 6697 for cross sectional component Study Location Brazil, Ghana, India, Norway, Oman and USA.  The study populations lived in • Socioeconomic conditions favourable to growth • Mobility was low • ≥20% of mothers followed WHO feeding recommendations and • Breastfeeding support was available The mothers were non smokers and breast feeding their children
  • 40.
     Why MGRSis unique? – Growth standards produced by selecting healthy children living under conditions likely to favour achievement of their full genetic growth potential. MGRS data included  Weight and head circumference at all ages,  Recumbent length (longitudinal component),  Height (cross-sectional component),  Length and Height (between 18 to 30 months)  Arm circumference, triceps and subscapular skinfold thickness (all children aged ≥3 months)
  • 41.
    SALIENT FINDINGS INMGRS  Striking similarity in linear growth across the diverse populations were studied.  An evaluation of the differences in length of participants from birth to 2 yrs of age within and among the MGRS sites demonstrated 70% of the total variance in length was due to inter individual differences and only 3% was due to inter site differences  Greater genetic variability resides within populations than among populations

    How to plotmid parental height  Mid parental height is necessary to understand child’s genetic potential so that child’s current height percentile can be checked against MPH percentile.  Involves a calculation and plotting at 18 years to know the mid parental percentile  MPH = (fathers heigh + mothers height)/ 2 +/- 6.5  This value is plotted on charts, and gives an idea estimate of target height for the child and the percentile it is likely to follow  Projected adult height = MPH +/- 8.5cm
  • 76.
    How to plotmid parental height  For ex: Fathers height 176cm Mothers height 168cm MPH = (176 + 168)/2 +6.5 = 178.5  Present height 9 years: 126cm 

    Uses of growthchart 1.Growth monitoring 2. Diagnostic tool: for identifying "high-risk“ children. For example, malnutrition can be detected long before signs and symptoms of it become apparent 3. Planning and policy making: by grading malnutrition, it provides an objective basis for planning and policy making in relation to child health care at the local and central levels 4. Educational tool: because of its visual character, the mother can be educated in the care of her own child· and encourage her to participate more actively in growth monitoring
  • 108.
    Uses of growthchart 5. Tool for action: it helps the health worker on the type of intervention that is needed; it will help to make referrals easier 6. Evaluation: it provides a good method to evaluate the effectiveness of corrective measures and the impact of a programme or of special interventions for improving child growth and development. 7. Tool for teaching: it can also be used for teaching, for example, the importance of adequate feeding; the deleterious effects of diarrhoea. 8.Reassurance:It provides reassurance about child’s health and prevents parental anxiety.
