Effects of Malnutrition on Growth

When a child is not getting enough nutrition or is getting too much, he/she is described as being malnourished. Malnutrition puts children at greater risk of dying from common infections, increases the frequency and severity of such infections, and contributes to delayed recovery.

Many people confuse malnutrition as meaning ‘undernourished’ or not ‘getting enough to eat’. This is not true, since someone who has enough or too much to eat may also be malnourished or ‘overnourished’.

Aspects of malnutrition may include:

Underweight

prevalence of underweight children in Malaysia is 13.2%, it is one of the leading global risk for disease and is a risk factor for childhood mortality due to diarrhoeal disease, measles, malaria and pneumonia.

Overweight

prevalence of overweight in Malaysian children is 8%, it is the leading global risk for mortality and it is responsible for raising the risk of chronic diseases such as heart disease, diabetes and cancer.

Stunting

Prevalence of stunting among Malaysian children in 2006 was 15.8%. Poor nutrition in the first 1,000 days of a child’s life has been known to lead to stunted growth, which is irreversible and associated with impaired cognitive ability and reduced school and work performance.

Wasting

Acute malnutrition, or wasting, develops as a result of a failure to gain weight. Wasted children weigh far less than is appropriate for their height. Wasting can lead to diseases such as tuberculosis, Lou Gehrig’s disease, and multiple sclerosis.

Micronutrient deficiency

Also termed ‘hidden hunger’, is caused by a lack of essential vitamins and minerals (e.g. vitamin A, zinc, iron, magnesium) in the diet. It can lead to illness, blindness, premature death, reduced productivity, and impaired mental development.

Symptoms of malnutrition in children can include:

  • failure to grow normally, both in terms of weight and height.
  • changes in behaviour such as appearing unusually irritable, sluggish or anxious
  • changes in hair and skin colour
  • taking a long time to recover from infections or wounds
  • poor concentration
  • persistent diarrhoea
  • depression

Your child’s weight and physical development can indicate whether he/she is malnourished. Therefore, they should be regularly assessed by a doctor in their first few years of life. Afterwards, you can monitor their growth yourself by measuring the body mass index (BMI) against a growth chart (see article Monitoring your Child’s Physical Growth).

Because nutrition has a lot to do with your child’s health and overall growth and development, your duty must be to provide it in adequacy. Providing a balanced variety of foods from different food groups at every meal is the best way to make sure a healthy mixture of nutrients enters your child.
