Undernutrition contributes to 45 percent of deaths among children under five. Global wasting prevalence stands at 6.9 percent. Exclusive breastfeeding reaches only 44 percent of infants under six months while vitamin and mineral deficiencies affect 1.7 billion children and women.
Key Takeaways
- 2021–2022 reductions in child wasting were not achieved for many countries; global wasting prevalence is estimated at 6.9% in 2022
- The global ready-to-use therapeutic food (RUTF) market size was $1.7 billion in 2023 (global market research estimate)
- The global baby food market size was $89.6 billion in 2023 (IMARC Group estimate)
- Global exclusive breastfeeding rate for infants under 6 months was 44% in 2023
- 70% of children aged 6–23 months globally are breastfed
- As of 2022, 64% of countries report that they have policies or legislation to protect breastmilk substitutes (including regulation of marketing)
- Undernutrition contributes to 45% of deaths in children under 5 globally (UNICEF nutrition action estimates)
- Stunting is associated with an average 10% reduction in adult productivity per study synthesis (Lancet child stunting series evidence)
- Iron deficiency is estimated to be responsible for 1.7 billion cases globally (WHO)
- 1.7 billion children and women were affected by vitamin and mineral deficiencies globally (micronutrient “hidden hunger”) — indicates large-scale micronutrient risk.
- Approximately 30% of children under 5 globally have low height for their age — indicates stunting prevalence (chronic undernutrition).
- Iron deficiency affects about 25% of the world’s population — a key driver of anemia risk for children and other groups.
- In 2022, 22% of children aged 6–23 months received at least one food from each of the four or more food groups — minimum dietary diversity share.
- In 2019, 36% of children under 2 months were fed with colostrum — measures early-life feeding practice important for nutrition.
- In 2022, 60% of children aged 6–23 months had access to food from at least two food groups — a proxy measure for dietary diversity.
Undernutrition remains widespread, with child wasting stalled and billions needing better feeding and micronutrients.

1.7 billion children and women were affected by vitamin and mineral deficiencies globally (micronutrient “hidden hunger”) — indicates large-scale micronutrient risk.
02
Approximately 30% of children under 5 globally have low height for their age — indicates stunting prevalence (chronic undernutrition).
03
Iron deficiency affects about 25% of the world’s population — a key driver of anemia risk for children and other groups.
04
Zinc deficiency contributes to an estimated 136,000 deaths per year in children under 5 — highlights the mortality burden linked to inadequate zinc.
05
About 1 in 4 children worldwide under 5 are affected by stunting — indicates chronic undernutrition prevalence.
Interpretation
Public Health Burden Interpretation
With 1 in 4 children under 5 affected by stunting and vitamin and mineral “hidden hunger” reaching 1.7 billion children and women globally, childhood nutrition remains a major public health burden tied to chronic undernutrition and widespread micronutrient deficiencies.

01
The cost of a package of nutrition-specific interventions for 2020–2030 is estimated at about $7per child per year on average in high-burden settings (2013–2020 costing context) — illustrates investment needs.
02
$49 billion per year would be required to scale up nutrition interventions globally to reach 2030 goals — investment gap estimate.
03
In 2023, UNICEF procured more than 0.5 million metric tons of therapeutic nutrition products (RUTF/RUSF) — bulk supply scale.
04
Micronutrient powders (MNP) are used in programs to deliver iron and other micronutrients; UNICEF reports distributing 3.1 billion sachets in 2022 — program supply volume.
Interpretation
Policy & Program Economics Interpretation
From a Policy & Program Economics perspective, meeting 2030 nutrition goals is projected to require an investment gap of about $49 billion per year, even though typical nutrition-specific interventions cost roughly $7 per child annually, with UNICEF scaling delivery through massive procurement such as over 0.5 million metric tons of therapeutic products in 2023 and distributing 3.1 billion sachets of micronutrient powders.
