Nutrition
ocuses on promoting and

Public health nutrition
has been a major concern in
both economically developed and less developed
countries.
undernutrition
manifests as micronutrient deficiencies,
wasting, and stunting in childhood and nutrition-related
chronic diseases in adulthood.
Undernutrition
like obesity, type 2
diabetes, cardiovascular disease, and common cancers,
now dominate the global nutrition-related disease
burden.
Nutrition-related chronic diseases
the acquisition, synthesis, and dissemination of
knowledge relating nutrition to health and disease;

Intermediate
(inadequate length/height for age) captures

indicator that includes elements of stunting and wasting
underweight
a severely stunted child faces a
_____ times higher risk of dying, and a severely wasted child is at a ____ times higher risk.
- four
- nine
Specific nutritional deficiencies such as _______, ________, __________ deficiency also increase the risk of death.
vitamin A, iron or
zinc
Undernutrition can cause various diseases such as
blindness due to _________ deficiency and neural tube
defects due to _____________
- vitamin A
- folic acid deficiency
Poor nutrition in the first 1,000 days of children’s lives can
have irreversible consequences. It means they are -
● forever, stunted.
● susceptible to sickness
● more likely to become overweight when they enter
adulthood.
● and more prone to non-communicable disease.
● About one-third of under-five mortality is attributable to
under-nutrition
The circumference of the child’s upper arm half way
between their shoulder and elbow provides an indication of acute malnutrition independent of the child’s age
MID UPPER ARM CIRCUMFERENCE (MUAC)
If the child’s arm is less than ______ in circumference, she is severely malnourished;
11.5cm
if the child’s arm is between _____and ______ in circumference, she is moderately malnourished
11.5
and 12.5cm
The values for muac are appropriate for chidren
6 months to 60 months.
When assessing weight-for-height, infants and children
under 24 months of age should have their lengths
measured ________
lying down (supine).
Children over 24 months of age should have their heights
measured while _________.

For simplicity, however, infants and children under 87 cm
can be measured _______ and those
above 87 cm _______-
