16. Discussions

17. Key points
• Optimal growth assessment requires serial measurements plotted on
appropriate growth charts
• Nutrition is the main driver of growth in children under 2 years of
age. Most cases of slow weight gain are secondary to inadequate
caloric intake
• Slow weight gain is commonly multifactorial in origin, with
psychosocial stressors often a significant contributor
• Small and otherwise healthy babies following a growth percentile line
may not need any investigations

18. IDENTIFY NORMAL
GROWTH PATTERN IN
AN INFANT

19. WEIGHT
• Lose 10-15% of their birth weight in first 7-10 days of life due to:
I. Excretion of excess extravascular fluid
II. Possibly poor intake (intake improves as colostrum is replaced by
higher fat milk, as infant learn to latch on and suck more
efficiently, and as mother become more comfortable with feeding
technique)
• 1st 3months of life, rate of weight gain 25g/day
Babies usually regain their birth weight by 2nd week
• Double birth weight by 5 month age
• Triple birth weight by 1 year of age
• Weight estimation for children
infant (age in months x 0.5 )+4
children 1-10 years (Age in yr +4) x 2

Measuring and plotting
Measuring Weight
Babies should be weighed without any
clothes or nappy
Children older than two years can be
weighed in vest and pants, but no shoes,
footwear, and dolls or teddies in hand
Only class III clinical electronic scales in
metric setting should be used

Electronic
Scales

21. HEAD CIRCUMFERENCE
• At Birth - 13.5 inches (35 cm)
• rate of growth in preterm infant is 1cm/week but
reduce with age. head growth follow that of term
infant when chronological age reach term
• COH increase 12 cm in 1st year of life (6 cm 1st 3
months, 3cm in second 3 months and 3 cm in last 6
months)
• 5-12 y 0.33cm/year

Measuring and plotting
Measuring Head Circumference
Head circumference should be
measured using a narrow plastic or
disposable paper tape
Measurement should be taken
where the head circumference is
widest

23. LENGTH
• Preterm infants = average 0.8- 1.0cm/week.
• Term infants = average 0.69- 0.75cm/week.
Age Length
Birth 50cm
6 months 68cm
1 year 75cm
3 years 90cm
4 years Double birth length (100cm)
5 – 12 years 5 cm yearly

Measuring and plotting
Measuring Length
Measure length before age 2 years if concerned.
Length should be measured without nappy or footwear.
Use proper equipment (length board or mat) as any other
method is too inaccurate. Requires two measurers

25. THE CAUSES OF FAILURE TO
THRIVE IN AN INFANT

26. DEFINITION
Given to malnourished
infants & young children
who fail to meet expected
standards of growth : Fails
to gains weight / length /
head size / development.
Related to organic,
environment and
psychosocial causes.
Nelson, essential of Peadiatrics, 6th edition.

27. DEFINITION
Suboptimal weight gain in infants and toddlers
Inadequate weight gain when plotted on a centile
chart
Mild FTT – Fall across 2 centile lines
Severe FTT – Fall across 3 centile lines
Illustrated textbook of peadiatrics, 4th edition

28. DIAGNOSED BY:
Weight that falls or remains below the third percentile for age
OR
Weight that decreases, crossing two major percentile lines on the
growth chart over time
OR
Weight that is less than 80% of the median weight for the height of the
child

34. DEMONSTRATE THE
IMPORTANCE OF A FEEDING
HISTORY

35. The importance of a feeding history
• To know the current nutritional intake
• To provide the better look at correlating the infant’s
development with the types of food offered.
• To assess the adequacy of nutritional intake for
growth.
• To screen for undernutrition or nutritional deficiency.
• To detect the causes of undernutrition and exclude
other causes of FTT
• Planning of management

36. Feeding history
Breastfeeding
Formula feeding
Weaning
Types of
feeding :

37. Breastfeeding history
History Comments
1. Ask if the baby is breast fed
or bottled fed
•Full term newborn babies can obtain all the
nutritional needs from breast milk in their first 4-6
months (only breastmilk can supply the secretory Ig A,
lactoferrin, peroxidase, lysozyme).
2. The duration of exclusive
breastfeeding and mixed
breastfeeding
Exclusive breastfeeding reduces infant mortality due to
common childhood illnesses such as diarrhoea or
pneumonia, and helps for a quicker recovery during
illness.
3. Frequency per day Demand or timed
Well term babies should be given breast feed on
demand. (usually 8-12 times/day)
4. Strength of sucking Good sucking reflex means that the baby is well.
Otherwise baby may be too weak to suck.
5. Any difficulty in
breastfeeding
The common reasons to quit breastfeeding are:
 Low milk production
 Mastitis
 Flat or inverted nipples
 Sore nipples

38. Formula feeding history
History Comments
1. Type of formula Infant, special, soy formula
2. The amount and frequency of milk
intake
 1 oz= 30mls
 The milk requirement
Day 1: 60mls/kg/day
Day 2-3: 90mls/kg/day
Day 4-6: 120mls/kg/day
Day 7 onwards: 150mls/kg/day
3. Preparation of feeds and hygiene Bottle sterilization, water source
4. Who feeds the baby Placement of the infant for feeding

39. Weaning
History Comments
1. Ask about weaning and
when did the weaning start.
 Food is needed after 6 months of age in addition to
milk to satisfy the increasing energy demands of the
infant.
 However, babies should not be started on foods other
than milk before they are 4 months old as their
kidneys and digestive system are not fully developed.
2. The types of solid food
introduced
 Normally cereals are introduced and mix with food
such as stewed fruits, mashed banana and pumpkin.
 Gradually, at around 8 months, an eating pattern of 3
meals a day should emerge. The type and quantity of
food taken for breakfast, lunch and dinner should be
obtained to quantify total calorie intake.
3. Ask about the feeding
pattern (Abnormal feeding
pattern can cause
malnutrition)
 Refusal (selective to mode of feeding or to a specific
parent or selective for some types of food)
 Fixation (willingness to ingest only 1 type of
food/texture of food)

40. DESCRIBE THE
NUTRITIONAL
REQUIREMENTS FOR
CHILDREN

41. INTRODUCTION
1. Nutrient needs determined by:
 Body size
 Growth rate
 Age
2. A child’s requirement is higher than an adult’s.
3. Nutritional deficiency are more commonly seen in
infancy as young children have fewer body reserves
of all nutrients.

43. Source: National Coordinating Committee on Food and Nutrition (2005)

44. Recommended Nutrient Intake (RNI)
1. RNI for children do not differ for boys and girls
except for energy.
2. All RNI values has a margin of safety except for
energy
3. RNI for most nutrients is higher than physiological
needs of most children.
4. If nutrient intake of a child less than RNI, it does not
necessarily mean child has nutritional problem.

45. Nutrient Recommendations
• Based on Malaysian Dietary Guideline (MDG) 2010:
Key message 12:
Practice exclusively breastfeeding from birth until six months and continue to
breastfeed until two years of age.

46. Key recommendations:
• Prepare for breastfeeding during pregnancy
• Initiate breastfeeding within one hour of birth
• Breastfeed frequently and on demand
• Give only breast milk to baby below six months with no
additional fluid or food
• Continues to give babies breast milk even if baby is not with
the mother
• Introduce complementary foods to baby beginning at six
months of age
• Lactating mothers should get plenty of rest, adequate food and
drink to maintain health
• Husbands and family members should provide full support to
lactating mothers

53. FORMULATE THE APPROACH
TO MANAGEMENT OF A
CHILD WITH FAILURE TO
THRIVE

54. Calories required for catch-up
• Children with failure to thrive require 150% of
Recommended Daily Requirement of calories
• Schedule: Replacement calories needed per day for
malnourished and catabolic infant
Age 0-6 months:
130-150 KCal/kg/day (high)
150-220 KCal/kg/day (very high)

55. ORGANIC FAILURE TO THRIVE
Treat underlying medical condition
Caloric supplementation
• Depend on severity and underlying medical problems.
• The responds depends on : (Specific diagnosis,
medical management, severity of the failure to
thrive.)
Monitor amount of protein
• In children with renal failure

56. NON ORGANIC FAILURE TO THRIVE
