Pregnant and lactating women and young children less than three years are
most vulnerable to malnutrition.
Scientific evidence has shown that beyond the age of 2-3 years, the effects of
chronic malnutrition are irreversible. This means that to break the
intergenerational transmission of poverty and malnutrition, children at risk
must be reached during their first two years of life.
Child malnutrition is the single biggest contributor to under-five mortality due
to greater susceptibility to infections and slow recovery from illness.
Children who do not reach their optimum height or consistently experience
bouts of weight loss during childhood are affected in the long term in
numerous ways. They do not reach their optimum size as adults (and so may
have less physical capacity for work), their brains are affected (resulting in
lower IQs) and they are at greater risk of infection (which kills many children
during their early years).
Child malnutrition impacts on education attainment. The degree of cognitive
impairments is directly related to the severity of stunting and Iron Deficiency
Anaemia. Studies show that stunted children in the first two years of life have
lower cognitive test scores, delayed enrolment, higher absenteeism and more
class repetition compared with non-stunted children. Vitamin A deficiency
reduces immunity and increases the incidence and gravity of infectious
diseases resulting in increased school absenteeism.
Child malnutrition impacts on economic productivity. The mental impairment
caused by iodine deficiency is permanent and directly linked to productivity
loss. The loss from stunting is calculated as 1.38% reduced productivity for
every 1% decrease in height while 1% reduced productivity is estimated for
every 1% drop in iron status (source Haddad and Bouis, 1990).
Maternal malnutrition increases the risk of poor pregnancy outcomes
including obstructed labour, premature or low-birth-weight babies and
postpartum haemorrhage. Severe anaemia during pregnancy is linked to
increased mortality at labour.
