Malnutrition in Children
What is Malnutrition?
Malnutrition means a child is not getting the right amount or type of food for healthy growth. It includes both:
- Undernutrition – when a child is not getting enough food or nutrients.
- Overnutrition – when a child eats too much or unhealthy food, leading to overweight or obesity.
Malnutrition weakens a child’s body, brain, and future. It can lead to illness, poor school performance, and even death.
- Undernutrition
This includes:
- Wasting – child is too thin for their height
- Stunting – child is too short for their age
- Underweight – child is too light for their age
- Micronutrient deficiencies – not enough vitamins or minerals (e.g., iron, vitamin A, iodine)
Causes:
- Poverty
- Inadequate breastfeeding or weaning
- Frequent infections (e.g., diarrhea, malaria)
- Poor food access during droughts, floods, or conflict
- Cultural practices that limit certain foods
- Large family sizes with limited food
Signs of Undernutrition:
- Thin arms and legs
- Swollen belly (in severe cases)
- Slow growth
- Hair changes (thin, discolored)
- Tiredness and low energy
- Frequent illness
- Swollen legs and body
- Prominent bones
- Body rashes
- Overnutrition (Overweight and Obesity)
This is becoming more common in cities and even some rural areas.
Causes:
- Eating too many processed foods, sugary drinks, and fried snacks
- Lack of physical activity (e.g., too much sitting or screen time)
- Poor knowledge about balanced diets
- Feeding young children too much food or unhealthy foods.
- Excess body fat
- Child gets tired easily
- Trouble with movement or breathing
- At risk of diabetes, high blood pressure, and future heart problems
To grow well, children need:
- Energy (from foods like maize, cassava, rice, yam, and sweet potatoes).
- Proteins (from beans, eggs, milk, fish, groundnuts, meat).
- Vitamins and minerals (from fruits, vegetables, seeds, and local greens).
- Clean water and safe hygiene to avoid disease.
What Parents and Caregivers Can Do
✅ For Undernourished Children:
- Exclusively breastfeed for the first 6 months
- After 6 months, provide nutritious, soft, home-prepared meals
- Feed 3–5 times a day with a mix of grains, vegetables, proteins, and fruits
- Seek help from a health center for growth monitoring
- Use ready-to-use therapeutic foods (RUTF) if prescribed by a health worker
✅ For Overweight Children:
- Reduce sugary snacks, fried foods, and sodas
- Give more fruits, vegetables, whole grains
- Encourage active play and exercise
- Avoid forcing children to finish large meals when full
- Teach healthy habits early
Cultural Beliefs and Realities
Belief | Reality |
---|---|
A fat child is always healthy | Not always – overweight can lead to health problems |
A thin child is bewitched | Thinness may be due to poor nutrition or infection |
Only poor families have malnourished children | Even well-off families may feed children unbalanced diets |
Herbal mixtures cure poor appetite | Always consult a trained health worker first |
Apply herbal preparation over anterior fontanelle prevents diarrhea | Prominent skull bones are commonly due to malnutrition. So adequate feeding rather than local application is the solution. |
Go to a clinic or hospital if your child:
- Is losing weight
- Refuses to eat or breastfeed
- Has swelling in the feet or face
- Has diarrhea or fever with poor appetite
- Looks very thin or very tired
- Is overweight or gaining too much weight rapidly
Where to Get Help
- Local health centers and growth monitoring clinics
- Nutrition programs run by NGOs and governments
- Community health workers
- School feeding programs
- Organizations like UNICEF, WFP, and local ministries of health
Final Message
✅ Malnutrition can be prevented and treated.
✅ Good food, clean water, love, and care can save lives.
✅ Parents, caregivers, teachers, and communities all play a role.
