Tanzania saw a significant decrease in stunting among children under age five - from a national average of 48 percent in 1999 to 30 percent in 2022 - but challenges remain. The absolute number of stunted children increased in some regions, and other nutritional issues like anemia remain significant, impacting 59 percent of children under five and 42 percent of women aged 15 - 49. Key factors driving undernutrition include, widespread poverty affecting around 44 percent of Tanzanians, a lack of diverse and quality diets, inadequate access to essential health services (including water, sanitation, and hygiene), and poor infant and young child feeding practices.
