What Is
Child Wasting?

Without proper nutrition, children cannot grow up healthy and reach their full potential. They can become too thin for their height, a condition known as wasting, or significantly underweight. 

The most visible and life-threatening form of malnutrition, wasting disease, also known as severe acute malnutrition, weakens immune systems, leaving children vulnerable to disease, developmental delays and death. 

Severely wasted children are up to 11 times more likely to die of treatable infections and diseases like pneumonia, cholera, malaria and measles than well-nourished children. 

Millions of children under 5 worldwide are impacted by severe wasting  

"It's hard to describe what it means for a child to be 'severely wasted,' " said UNICEF Executive Director Catherine Russell. "But when you meet a child who is suffering from this most lethal form of malnutrition, you understand — and you never forget."

Those children require immediate treatment and care to survive.

UNICEF purchases and distributes 80 percent of the world's RUTF, a lifesaving treatment for severely wasted children

No child should die from malnutrition when the tools exist to prevent it. Early detection is key to successful outcomes. 

Once children are diagnosed, they can be treated with ready-to-use therapeutic food (RUTF), a shelf-stable, nutrient-rich peanut paste. With a regimen of three packets of RUTF daily, 90 percent of severely wasted children are able to recover fully in roughly six weeks. Without it, 90 percent do not survive.

UNICEF purchases and distributes approximately 80 percent of the world's supply of RUTF. In 2024, UNICEF and its partners reached over 9.3 million children with lifesaving treatment for severe wasting and other forms of severe acute malnutrition, primarily with RUTF. Specifically, UNICEF supported therapeutic feeding programs that provided RUTF to over 7.4 million children with severe wasting in 47 high-mortality countries.

What is Ready-to-Use Therapeutic Food?

UNICEF provides nutrition support during the critical first 1,000 days of a child's life 

To help prevent children from becoming malnourished in the first place, UNICEF works to ensure that pregnant mothers receive the prenatal care they need to deliver healthy babies, then promotes breastfeeding from the first hour of life to give newborns the best start in life.

UNICEF also provides fortified foods and micronutrients to young children during the crucial first 1,000 days, and supports health screenings to detect signs of malnutrition early, so children can be referred for treatment.

Breastfeeding Gives Children a Healthy Start

UNICEF and partners advocate for increased political will, investment and action to tackle child wasting

Good nutrition is the bedrock of child survival and development. A relatively small additional investment — by donors, governments and other financial instruments — would dramatically reduce child death rates. 

With partners like the Eleanor Crook Foundation, UNICEF works to strategically engage the public and decision makers to support and invest in child nutrition and end severe wasting by strengthening the systems children rely on.
