2. MALNUTRITION
WHO defines Malnutrition as "the cellular imbalance
between the supply of nutrients and energy and the
body's demand for them to ensure growth,
maintenance, and specificfunctions.“
Malnutrition is the condition that develops when the body does
not get the right amount of the vitamins, minerals, and other
nutrients it needs to maintain healthy tissues and organ
function.

3.  PROTEIN ENERGY MALNUTRITION
It is a group of body depletion disorders which
include kwashiorkor, marasmus and the intermediate
stages
 MARASMUS
Represents simple starvation . The body adapts to
a chronic state of insufficient caloric intake
 KWASHIORKOR
It is the body’s response to insufficient protein intake
but usually sufficient calories for energy

Protein-Energy
Malnutrition
St.Ann's Degree College for Women
 PEM is also referred to
as
protein-calorie
malnutrition.
 It is considered as the p
r

m
a
r
y
nutritional problem in India.
Also called the 1st
National Nutritional
Disorder.
 The term protein-
energy malnutrition (PEM)
applies to a group of related
disorders that
include marasmus,
kwashiork or, and
intermediate states of
marasmus-kwashiorkor.
 PEM is due to “food

”
between the intake and
requirement.

6. AETIOLO
GY

7. AETIOLOGY:
Different combinations of many aetiological
factors can lead to PEM in children. They
are:
 S o c i a l and Economic Factors
 B i o l o g i c a l factors
Environmental factors
 R o l e of Free Radicals & Aflatoxin
 A g e of the Host
St.Ann's Degree College for Women

8.  Amongst the Social,
Economic, Biological a
n
d
Environmental Factors
the common causes are:
St.Ann's Degree College for Women
 Lack of breast feeding and giving diluted formula
 Improper complementary feeding
 Over crowding in family
 Ignorance
 Illiteracy
 Lack of health education
 Poverty
 Infection
 Familial disharmony

9.  Role of Free Radicals & Aflatoxin: Two new
t
h

o
r
i
e
shave been postulated recently to explain the
pathogenesis of kwashiorkor. These include Free
Radical Damage & Aflatoxin Poisoning . These may
damage liver cells giving rise to kwashiorkor.
 Age Of Host :
 Frequent in Infants & young children whose rapid
growth increases nutritional requirement.
 PEM in pregnant and lactating women can affect the
growth, nutritional status & survival rates of their
fetuses, new born and infants.
 Elderly can also suffer from PEM due to alteration of
GI System

Primary PEM:
Protein + energy intakes below requirement for normal growth.
Secondary PEM:
 the need for growth is greater than can be supplied.
 decreased nutrient absorption

FEATURES

15. The clinical presentation depends
upon the type
, severity and duration of the
dietary deficiencies. The five forms
of PEM are :

17. KWASHIORKOR

St.Ann's Degree College for Women
 The term kwashiorkor is taken from the Ga language
of
Ghana and means "the sickness of the weaning”.
 Williams first used the term in 1933, and it
refers to an inadequate protein intake with
reasonable caloric (energy) intake.
 Kwashiorkor, also called wet protein-energy
malnutrition, is a form of PEM characterized primarily by
protein deficiency.
 This condition usually appears at the age of about
1
2months when breastfeeding is discontinued, but it
can develop at any time during a child's formative
years.
 It causes fluid retention (edema); dry,
peeling skin; and hair discoloration.

18.  Kwashiorkor was thought to be
caused by insufficient protein
consumption but with sufficient calorie
intake, distinguishing it from marasmus.
 More recently, micronutrient
and antioxidant deficiencies have
come to be recognized as contributory.
 Victims of kwashiorkor fail to
produce antibodies following vaccination
against diseases, including diphtheria and
typhoid.
 Generally, the disease can be treated by
adding food energy and protein to the diet;
however, it can have a long-term impact
on a
child's physical and mental development,
and in severe cases may lead to death.

21. MARASMUS

St.Ann's Degree College for Women
 The term marasmus is derived from the Greek
word marasmos, which means withering or wasting.
 Marasmus is a form of severe protein-energy
malnutrition characterized by energy deficiency and
emaciation.
 Primarily caused by energy deficiency, marasmus is
characterized by stunted growth and wasting of muscle and
tissue.
 Marasmus usually develops between the ages
of six months and one year in children who have been
weaned from breast milk or who suffer from weakening
conditions like chronic diarrhea.

27. A severely malnourished child
with features of both
marasmus and Kwashiorkor.
 The features of
Kwashiorkor are severe
oedema of feet and legs
and also hands, lower
arms, abdomen and face.
Also there is pale skin and
hair, and the child is
unhappy.
 There are also
signs of marasmus,
wasting of the muscles of
the upper arms, shoulders
and chest so that you can
see the ribs.
MARASMIC-KWASHIORKOR

28.  Some children adapt to prolonged insufficiency
o
ffood-energy and protein by a marked retardation
of growth.
 Weight and height are both reduced and
in the same proportion, so they appear superficially
normal.
NUTRITIONAL DWARFING

29.  Children with sub-
clinical PEM can be
detected by their weight
for age or weight for
height, which are
significantly below
normal. They may have
reduced plasma albumin.
They are at risk for
respiratory and gastric
infections

30. BIOCHEMICAL &
METABOLIC
CHANGES
St.Ann's Degree College for Women

31.  Significant findings in kwashiorkor include hypoalbuminemia
(10-25 g/L), hypoproteinemia (transferrin, essential amino
acids, lipoprotein), and hypoglycemia.
 Plasma cortisol and growth hormone levels
are high, but insulin secretion and insulinlike growth
factor levels are decreased.
 The percentage of body water and extracellular water
is increased.
 Electrolytes, especially potassium and magnesium,
are depleted.
 Levels of some enzymes (including lactase) are decreased,
a
n
d
circulating lipid levels (especially cholesterol) are low.
 Ketonuria occurs, and protein-energy malnutrition
may cause a decrease in the urinary excretion of urea because
of decreased protein intake.
 In both kwashiorkor and marasmus, iron deficiency anemia a
n
d
metabolic acidosis are present.
 Urinary excretion of hydroxyproline is diminished, reflecting
impaired growth and wound healing.

TREATMENT
St.Ann's Degree College for Women
  Ensuring nutritional rehabilitation.
 There are three stages of treatment.
1.Hospital Treatment
 The following conditions should be corrected.
 Hypothermia, hypoglycemia, infection,
dehydration, electrolyte imbalance,
anaemia and other vitamin and mineral
deficiencies.
2.Dietary Management
 The diet should be from locally available
staple foods - inexpensive, easily digestible,
evenly distributed throughout the day and
