What age groups are affected by kwashiokor?

Kwashiorkor primarily affects young children, particularly those between the ages of 1 to 5 years, who are weaned from breast milk and do not receive adequate protein in their diets. However, it can also occur in older children and adults in cases of severe malnutrition or food scarcity. The condition is most prevalent in areas with limited access to nutritious food and is often associated with a lack of dietary diversity.
