Stunting affected an estimated 22.9 per cent or 154.8 million children under 5 globally in 2016.
An estimated 6.0 per cent or 40.6 million children under age 5 around the world were overweight in 2016.
In 2016, wasting continued to threaten the lives of an estimated 7.7 per cent or nearly 52 million children under 5 globally.

The ultimate aim is for all children to be free of malnutrition in all its forms
Good nutrition allows children to grow, develop, learn, play, participate and contribute – while malnutrition robs children of their futures and leaves young lives hanging in the balance. Stunting is the devastating result of poor nutrition in early childhood. Children suffering from stunting may never grow to their full height and their brains may never develop to their full cognitive potential. Globally, approximately 155 million children under 5 suffer from stunting. These children begin their lives at a marked disadvantage: they face learning difficulties in school, earn less as adults, and face barriers to participation in their communities.
access to processed foods, along with lower levels of physical activity. While malnutrition can manifest in multiple ways, the path to prevention is virtually identical: adequate maternal nutrition before and during pregnancy and lactation; optimal breastfeeding in the first two years of life; nutritious and safe foods in early childhood; and a healthy environment including access to basic services and opportunities for physical activity. These key ingredients can deliver a world where children are free from all forms of malnutrition.
Wasting in children is the life-threatening result of hunger and/or disease. Children suffering from wasting have weakened immunity, are susceptible to long term developmental delays, and face an increased risk of death: they require urgent treatment and care to survive. In 2016, nearly 52 million children under 5 were wasted and 17 million were severely wasted.
Despite this opportunity, the UNICEF, WHO, World Bank global and regional child malnutrition estimates from 1990 to 2017 reveal that we are still far from a world without malnutrition. The joint estimates, published in May 2017, cover indicators of stunting, wasting, severe wasting and overweight among children under 5, and reveal insufficient progress to reach the World Health Assembly targets set for 2025 and the Sustainable Development Goals set for 2030.
There is also an emerging face of malnutrition: childhood overweight and obesity. There are now nearly 41 million overweight children globally, an increase of 11 million since 2000. The emergence of overweight and obesity has been shaped, at least in part, by industry marketing and greater
Improving children’s nutrition requires effective and sustained multi-sectoral nutrition programming over the long term, and many countries are moving in the right direction. Regular data collection is critical to monitor and analyse country, regional and global progress going forward.
Forms of malnutrition* highlighted in this key findings report Stunting refers to a child who is too short for his or her age. Stunting is the failure to grow both physically and cognitively and is the result of chronic or recurrent malnutrition. The devastating effects of stunting can last a lifetime.
Overweight and stunted
Stunted and wasted
Overweight refers to a child who is too heavy for his or her height. This form of malnutrition results from expending too few calories for the amount consumed from food and drinks and increases the risk of noncommunicable diseases later in life.
Wasting refers to a child who is too thin for his or her height. Wasting, or acute malnutrition, is the result of recent rapid weight loss or the failure to gain weight. A child who is moderately or severely wasted has an increased risk of death, but treatment is possible.
* Some children suffer from more than one form of malnutrition – such as stunting and overweight or stunting and wasting. There are currently no joint estimates for these combined conditions.
