At what age is wasting most prevalent?
• Wasting occurs more commonly in infants and younger children often during the weaning period.– Complementary foods may be inadequate
nutritionally.
– Complementary foods and drinks are often not clean and can cause diarrhea.

Who is at risk of stunting?
• Stunting occurs over a long period of time.
• Usually less apparent until after 2 years of age.
• Action is needed during the early years to prevent stunting.

PROTEIN ENERGY MALNUTRITION (PEM)
...a result of deficiencies in any or
all nutrients (includes micronutrients, as
well as macronutrients).
MICRONUTRIENT DEFICIENCY DISEASES
(MDD’S) ...occur as a result of deficiencies in specific micronutrients (vitamins or minerals).
