What happens to Children who are not killed by The Cycle of Malnutrition?
4.26 script - Stanford/Khan Academy
There are approximately 3 billion people who survive on less than 2 dollars a day. And as a result of this we have a cycle of malnutrition - especially among our young children. At present there are about 160 million children under the age of 5 who are malnourished in our world. And these are children who are mainly living in developing parts of the world -in Asia, Africa, parts of Latin America.
This cycle of malnutrition is what I would like to go through today.
One of the biggest concerns that we have when we have a child experiencing malnutrition is the fact that child's immune system is likely to be compromised: and that means that child is less likely to be able to fight off diseases. So a compromised immune system is going to lead to an increase in both the duration and the number of diseases that child experiences growing up
GROWTH AND DEVELPOMENT
Other things malnutrition does is that it inhibits or slows down both the physical growth of the child (increases in weight, height, head circumference) and also it inhibits or slows down the development of the child. When we are talking about development we are talking about maturation of the child. And development can occur either with or without physical growth. So an example without physical growth would be learning to speak or learning how to walk.. An example with physical growth would be pubertal development or debvelopmenta round the time of puberty.
So all of these things : delays in growth, delays in development, and an increase in number of severity and number of diseases experienced by the child- all of these things are going to lead to an overall decrease in the lifetime productivity of that child. That child is less likely to be a highly functioning member of the society in which that child lives because of the fact that they are small, and unable or less able to learn effectively, and also because they are often ill. So what's going happen then - obviously children grow up, and what happens when you have widespread malnutrition is that decreased productivity becomes a characteristic of all the children who are becoming adults within a society. And that is going to lead to a decrease in the countrywide development. And the first symptom of that is going to be widespread poverty , we going to see a lot of poverty and of course one of the follows-on of widespread poverty is malnutrition in children.
CYCLE OF MALNUTRITION
So you can see that this is a self-perpetuating cycle, we have malnutrition in many children around the world leading to delayed growth or stunted restricted growth and development, decreases in child's ability to battle disease leading to increased illness- all of these things contributing decreased productivity of the child, and that is going to lead to decreased productivity of the country, widespread poverty and again malnutrition
