Stunting

Stunting is a condition that results from prolonged undernutrition, typically occurring before the age of two. It is characterized by a low height-for-age, and can have long-term effects on a child's growth, development, and overall health.

Causes

The primary cause of stunting is chronic undernutrition, particularly in the crucial period from conception to the child's second birthday. Other factors that can contribute to stunting include inadequate maternal nutrition, inadequate feeding practices, and infections such as diarrhea.

Effects

Stunting can have a range of long-term effects. It can lead to reduced physical and mental development, increased risk of obesity and non-communicable diseases in adulthood, and decreased work capacity and productivity. Stunting can also have intergenerational effects, as women who were stunted in childhood are more likely to give birth to smaller infants.

Prevention and treatment

Prevention and treatment of stunting involves improving maternal nutrition and feeding practices, treating and preventing infections, and providing psychosocial stimulation. Interventions can include nutritional supplements, education on feeding practices, and immunization against common infections.

Global prevalence

Stunting is a global problem, affecting an estimated 149 million children under five years of age in 2020. The highest prevalence is in Africa and Asia, where nearly one in three children are affected.
