Explanation:

Stunting, wasting and overweight

• Stunting, or low height for age, is caused by long-term insufficient nutrient intake and frequent infections. Stunting generally occurs before age two, and effects are largely irreversible. These include delayed motor development, impaired cognitive function and poor school performance. Nearly one third of children under five in the developing world are stunted.
• Wasting, or low weight for height, is a strong predictor of mortality among children under five. It is usually the result of acute significant food shortage and/or disease. There are 24 developing countries with wasting rates of 10 per cent or more, indicating a serious problem urgently requiring a response.
• Overweight is an increasingly important issue all over the world: 20 developing countries have rates above 5 per cent. Childhood undernutrition and overweight co-exist in many countries, leading to a double burden of malnutrition.
