HORMONAL ROLE
RETURN TO INDEX
Intrauterine
1. Chorionic gonadotropins
2. Placental lactogen
3. Insulin
4. Thyroxin (skeletal growth)
Infancy & childhood
1. Thyroxin
2. Growth hormone
Adolescence
Sex hormones (Estrogen &
androgen) are responsible for
growth spurt during puberty

I. GENETIC FACTOR
• Most important deciding factor of growth.
• Up to certain extend , gene expression decides the height.
• Children of tall and heavy parents are likely to have the same stature.
• Some races are taller in comparison to others.
• Difference between male and female growth pattern, adolescent spurt appear to be
genetically controlled via the hypothalamus.
RETURN TO INDEX

2. NUTRITIONAL FACTOR
• For optimum growth , balanced diet is necessary.
• Balanced diet must be adequate not only in calories but also in proteins, carbohydrates,
fats, vitamins, minerals.
• Their requirements are increased during active periods of growth.
• Undernutrition and malnutrition in childhood is responsible for stunting of growth.
• If lack of nutrition is prolonged severe- stunting occurs which may be irreversible.
• If lack of nutrition is less severe & for short period- stunting may be reversible by restoring
normal diet leading to compensatory increase in rate of growth. This is called as Catch Up
growth.
• The mechanisms for catch up growth are unknown, but recent evidence suggests that it
may be related to the rate of stem cell differentiation within the growth plates.
RETURN TO INDEX

2. NUTRITIONAL FACTOR
• Undernutrition affects the growth of different organs and tissue unevenly
• Dietary deprivation affects muscles and fat more than bone.
• Skeletal maturation is less affected than skeletal growth.
• Total brain growth is inhibited more than myelination.
• At puberty malnutrition affects the genitals less commonly than other organs.

GROWTH MONITORING [GM]
• What is growth monitoring
• Growth monitoring is the regular measurement of a child's size (weight, height or
length and head circumference) in order to document growth.
• The child's size measurements must then be plotted on a growth chart.
• This is extremely important as it can detect early changes in a child's growth.

I. ANTHROPOMETRIC MEASURES
RETURN TO INDEX

Anthropometry: Introduction
•Anthropos - "man" and Metron "measurement”
•A branch of anthropology that involves the quantitative measurement of the
human body.
•Gold standard of nutritional assessment. It is the single most portable,
universally applicable, inexpensive and non-invasive technique for
assessing the size, proportions and composition of the human body.
•It is used to evaluate both under & over nutrition.
•The measured values reflects the current nutritional status & don’t
differentiate between acute & chronic changes
RETURN TO INDEX

• How can you assess anthropometric measures?
• Get an accurate body measurement e.g. weight, height, head circumference,
etc.
• Compare this measurement with growth standards obtained from normal
individuals of same age, sex, and community.
• This can be done by plotting this measurement on percentile or Z score growth
charts of the same age & sex
RETURN TO INDEX

• Parameters.
• Infants 0 to 2 years:
1. Weight
2. Length
3. Weight for length
4. Head circumference
• Children and adolescents 2 to 20 years:
1. Weight
2. Height
3. Body mass index (BMI)
• Mid Arm Circumference (MAC)
• Skin fold thickness
RETURN TO INDEX

Child Anthropometry
• Basic measurements in children include:
1.WEIGHT
• Clothing to be removed.
• Baby weighed on clean calibrated scale.
• The measurement is taken to at least 2 decimal places for accuracy in kg.
2.HEIGHT (LENGTH)
• An infantometer is used.
• The baby is placed supine with head against appropriate surface.
• The baby is held in a fully extended position with the heels at a 90º position.
• The measurement is taken to at least 3 time
• The measurement is taken to the nearest 0.1cm.
3.OFC (Occipitofrontal circumference)
• The OFC of the baby is measured to the nearest 0.1cm with a firm tape
measure placed appropriately.
• The measurement is taken to at least 3 time
RETURN TO INDEX

Components of Anthropometric Assessment:
• Height (Length )-for-age
• The maximum growth potential of an individual is decided by hereditary factors.
• Among the environmental factors, the most implicant being nutrition and morbidity.
• Is considered an index of chronic or long duration malnutrition (3).
• Weight-for-Height
• Weight-for-height is now considered more important than weight alone.
• helps to determine whether a child is within range of "normal" weight for his height (2)
• Mid-arm Circumference
• Yields a relatively reliable estimation of the body's muscle mass.
• The reduction of which is one of the most striking mechanisms by which the body adjusts to inadequate
energy intakes (2).
• Arm circumference cannot be used before the age of one year
• between ages one and five years, it hardly varies (2).

Rules of Thumb for Growth
1.WEIGHT
• Weight loss in first few days: 5-10% of birthweight
• Return to birthweight: 7-10 days of age
• Double birthweight: 4-5 months
• Triple birthweight: 1 year
• Daily weight gain:
• 20-30 g for first 3-4 months
• 15-20 g for rest of the first year
2.HEIGHT
• Average length: 20 in. at birth, 30 in. at 1 year
• At age 4 years, the average child is double birth length or 40 in.
3.HEAD CIRCUMFERENCE (HC)
• Average HC: 35 cm at birth (13.5 in.)
• HC increases: 1 cm per month for first year (2 cm per month for first 3 months, then slower)

WEIGHT
WEIGHT IS ONE OF THE BEST CRITERIA FOR ASSESSMENT
OF GROWTH AND A GOOD INDICATOR OF HEALTH AND
NUTRITIONAL STATUS OF CHILD.

WEIGHT
At birth is 3 - 3.5 kg
1st week
Weight loss of 5-10 % during the first
3 to 4 days of life.
Weight regained by the
7th —10th day of life.
Daily weight gain during infancy:
• 20-30 g / day during the first 3- 4 months
• 15-20 g / day for the rest of the first year.
Daily weight gain during infancy
• 3/4 kg/ month for the first 4 months
• 1/2 kg/ month for the second 4 months
• 1/4 kg/ month for the third 4 months .

Weight
• WEECH’S FORMULAcalculate the expected weight (KG)
a) 3 – 12 months
Expected weight(kg) = age (months) + 9 / 2
b) 1- 6 years
Expected weight(kg) = age (years) x 2 + 8
c) 7 – 12 years
Expected weight(kg) = (age (years) x 7) - 5 / 2
• The periodic recording of weight on a growth chart is essential for monitoring the growth of under-five
children.
• Presence of wastingalone indicates acute energy deficit.
• While stuntingimplies long-term energy deficit
• A combination of wasting/stuntingimplies an acute nutritional insult superimposed on long-
term energy deficit.

MIDPARENTAL HEIGHT
• Prediction of adult height
• The calculation of mid-parental height is useful to evaluate the child's genetic
endowment for linear growth.
• The determination is made by using the following formulae:
• Boys = (Mother's height in cm) + (Father's height in cm) / 2 + 6.5 cm
• Girls = (Father's height in cm) + (Mother's height in cm) / 2 - 6.5 cm
• Draw the range in the growth chart

PLOT MPH AND TARGET RANGE ON
GROWTH CHART
• Extend 10 cm above and below from
MPH point: Target range
• Extend an imaginary line backwards
from the lower end of the target range

HEAD
CIRCUMFERENCE
It is related to brain growth and development of intracranial volume.
RETURN TO INDEX

HEAD CIRCUMFERENCE
•When to measure
• Occipitofrontal circumference (OFC) should be measured in all children at health maintenance visits
between birth and three years of age.
• OFC should also be measured at each visit in children of all ages with neurologic or developmental
complaints
•Brain growth takes place 70% during fetal life, 15% during infancy and remaining 10% during pre-school years.
•Measurement of OFC in the newborn may be unreliable until the third or fourth day of life since it may be
affected by caput succedaneum, cephalohematoma, or molding
•Measuring technique
• The head circumference is measured by placing the tape over the occipital protuberance at the back and just
over the supraorbital ridge and the glabella in front.

Skinfold thickness
• Definition: the amount of subcutaneous fat when the fold is lifted and
• Skin fold thickness gives estimation of fat.
• Can be measured by Lange’s of Harpenden’s Skin fold calipers.
• The triceps skinfold is necessary for calculating the upper arm muscle circumference.
• Its thickness gives information about the fat reserves of the body, whereas the
calculated muscle mass gives information about the protein reserves.
• In clinical practice, we can measure:
• Triceps skin fold (back side middle upper arm, normally about 13-14 MM
• Subscapular skinfold (under the lowest point of the shoulder blade)
• Triceps skin fold thickness is < 10 mm in malnutrition.

Body proportions
• Useful body proportions: that may help in understanding various growth
disturbances include:
• Upper Segment / Lower Segment ratio
• Arm span/ height.
• CC / HC ratio
• Upper segment (US} / lower segment ratio (LS)
• LS: is measured as the length between pubic symphysis and the heel while
the US is calculated by subtracting the lower segment length from stature.

• Normal US/LS ratio
• The ratio is 1.7:1 at birth.
• The ratio is 1.3:1 by 3-4 years
• The ratio is 1:1 by 7 to 10 years
• Diseases with abnormal US/LS ratio: Short stature with:
• High US/LS ratio (short limbs) as in achondroplasia, rickets...
• Decreased US/LS ratio (short trunk): as in mucopolysaccharidoses,
hypogonadism
• Norma} US/LS —^proportionate dwarfism as hypopituitarism, constitutional

• It is measured in years by the radiographic examination of ossification centers; most
often using the Greulich-Pyle bone age scale
• At > 6 month onwards  by x-ray over the left wrist
• No. of ossification centres in wrist = Age(yrs)+1
• In late childhood  by assessing fusion of epiphysis

2. Upper end of tibia.
3. Calcaneus, talus & cuboid
• “X ray knee in newborn help assess intrauterine skeletal maturation ; it is a good screening
tool for congenital hypothyroidism”
• Carpal bones start ossification after birth as follow
• The 1st carpal bone  ossifies at about 2nd month of age.
• The 2nd carpal bone  ossifies by the end of the first year.

• Definition
• Graphic method for assessment of physical growth
• By plotting various growth parameters against the age (e.g., Weight & height for age...)
• A growth chart is a graphic design of a growth reference presented as a visual display for clinical use.
• comprise growth curves which display both the size of the newborn at a series of ages, and at the same
time their growth rate or growth velocity overtime, based on the slope of the curve.
• the charts have become an important tool in child health screening and pediatric clinical workup.
• Each parameter separate for boys (Blue) & girls (pink)

centile lines and are based on measurements
of many children.
• It describes the percentage of children
expected to be below that line; 50% below
50th centile
• Normal value lies between the 3rd and 97th
centile
• Percentiles explained
• 97th percentile
• 3 in approximately 100 children are above this line
• 3rd percentile
• 3 in approximately 100 children are below this line
• 50th percentile
• Half the children at any age are above this line and
half are below

GROWTH CHARTS
ADVANTAGES OF ANTHROPOMETRY
1.Less expensive & need minimal training
2.Readings are reproducible.
3.Objective with high specificity &
sensitivity
4.Measures many variables of nutritional
significance (Ht, Wt, MAC, HC, skin
fold thickness, waist & hip ratio & BMI).
5.Readings are numerical & gradable on
standard growth charts
Limitations of Anthropometry
1.Inter-observers errors in measurement
2.Limited nutritional diagnosis
3.Problems with reference standards, i.e.
local versus international standards.
4.Arbitrary statistical cut-off levels for
what considered as abnormal values.
