Impact of low nutrient intake on infant mortality rate in sub-Saharan Africa

Abstract

Eating good quality food is necessary for good health given the importance of food to
the people as one of their most basic needs, which they cannot live without, because it
gives energy for everything they do (walking, working, talking, playing, reading and
even thinking and breathing). Food also provides the energy for the nerves, muscles,
heats and glands to work; and the nourishing substances the bodies require to build
and repair tissues and regulate the body organs and systems.
Given these assertions, a healthy body through adequate nutrient intake will not only
affect the capacity of an individual to learn, but will improve the well-being and the
productivity of that individual and the economic growth of the nation in general.
Adequate nutrient intake will not only reduce the tendency for individuals to contact
communicable diseases like tuberculosis, but if not properly managed can increase
diseases of dietary excess like obesity. On the contrary, when there are inadequate
intakes of nutrients, the resultant effect will include malnutrition, which in turn could
lead to impaired mental development, poor scholastic and intellectual performance
and a wide range of illnesses, disability and possibly death, most especially among
infants.
Using a cross-country data, drawn from sub-Saharan Africa and a multiple regression
analysis, this paper examines the extent to which low nutrient intake has impacted on
infant mortality rate in sub-Saharan Africa. The results obtained first indicate that the
model used for the study is of good fit, since 61 percent variation in the dependent
variable (infant mortality rate) is explained by the independent variables (low nutrient
intake, proxied by daily per capita calories intake and per capita income). Second, the
result also indicates that low nutrient intake has a significant influence on infant
mortality rate and third nutrient intake (drawn from the values of the co-efficient and
t-value) has the expected sign, which is inversely related to infant mortality rate, thus
fulfilling our a-priori expectation which said that the lower the nutrient intake, the
more the rate of infant mortality rate in sub-Saharan Africa.
Given these result, measures such as, increase in food availability, macro-economic
stability (especially, a reduction in inflation rate and exchange rate stability),
improved nutrition through micro-nutrients fortification and supplementation,
ensuring good governance and combating ethnic/religious/ civil conflicts and
HIV/AIDS are suggested as possible solutions to improving nutrient intake in sub-
Saharan Africa.
