Abstract
In Tanzania, chronic undernutrition is
at 35 percent among children under five. This makes the
country home to the third highest population of children
with chronic undernutrition in Sub-Saharan Africa, just
after Ethiopia and the Democratic Republic of Congo. This
brief provides an overview of the trends in undernutrition,
as indicated by stunted growth, over time and by subgroups
of gender, age in months, rurality, geography, and poverty.
It also provides a geo-spatial stunting map which shows 1km
x 1km pixel-level estimations of stunting rates. Using the
UNICEF Synergies Approach (1990) and drawing on existing
scientific literature, the brief then outlines the theory
behind different pathways to chronic undernutrition through
inadequate food, care, environment, and health services.
Further econometric analysis has been conducted on the DHS
2016 data using Shapley decomposition, to identify the
relative contributions of various determinants including
water supply, sanitation, and hygiene (WASH) variables in
determining stunting rates, and hence chronic undernutrition
in the Tanzania. The relative contributions of other factors
such as poverty, the child’s characteristics, mother’s
characteristics and location are also highlighted. Finally,
it provides operational and policy implications along the
lines of multisectoral and nutrition-sensitive approaches
for intervention design to reduce stunting in Tanzania.
