One of the main reasons why children are more likely to develop malnutrition is because of their poor sanitation and hygiene. Those who are living in developing areas may not always have the means to bathe and to get proper food. They will then become deficient in vitamins. Children are more affected because they are still in the development process.
The lack of the vitamins and nutrients they need may lead to some diseases that will make them even more malnourished such as getting intestinal worms and developing diarrhea. There are also some children who are suffering from chronic diseases that will be more prone to malnutrition as compared to others.
