Classifying a 30-Month-Old with Stunting and Moderate Wasting
A 30-month-old girl is brought by her mother to an anganwadi centre in a rural block of Salem district. Her weight is 9.4 kg, length 82 cm and mid-upper-arm circumference 12.8 cm. There is no bilateral pedal oedema. Her hair is sparse and hypopigmented, and she is irritable but alert and accepts food during the appetite test. The mother reports that the child eats only two meals a day, mostly rice water with a little salt, and continues to breastfeed on demand. No egg, pulse, milk or fruit has been given in the past week. She had diarrhoea twice in the last two months and has not received vitamin A after 18 months. The medical officer records no fever, no cough and no visible severe disease. The anganwadi worker wants to know whether the child has severe acute malnutrition and whether she must be sent to the nutrition rehabilitation centre or can be managed in the community.
1. Using weight-for-age, length-for-age, weight-for-length and MUAC, classify this child's nutritional status and decide whether she has severe acute malnutrition.

Working through the indicators (WHO Child Growth Standards)
- Weight-for-age: 9.4 kg at 30 months is below −2 SD of the median (about 12.0 kg) - she is underweight.
- Length-for-age: 82 cm is far below the median (about 90.7 cm), close to −3 SD - severe stunting.
- Weight-for-length: expected weight at 82 cm is about 10.9 kg; 9.4 kg is roughly 86% of the median, which is moderate wasting (70–79% would indicate severe wasting).
- MUAC: 12.8 cm is just above the 12.5 cm cut-off, so MUAC does not classify her as severe acute malnutrition.
- Oedema: absent.
Classification She has severe chronic undernutrition (stunting) with moderate acute malnutrition (moderate wasting and borderline underweight). She does not meet the criteria for severe acute malnutrition: no bilateral pitting oedema, MUAC above 12.5 cm, weight-for-length above −3 SD, and she passes the appetite test with no medical complication.
Decision She can be managed in the community through the anganwadi and health system, not admitted to the nutrition rehabilitation centre. The discordance between MUAC and weight-for-length is exactly why several indicators must be read together: relying on MUAC alone would have missed her wasting, and relying on weight alone would have missed the stunting that explains her long history.
2. The mother asks why the child is not gaining weight when she gives rice water and breast milk. Explain the feeding problems and give a corrected feeding plan.

Why she is not gaining
- Energy density is far too low. Rice water supplies roughly 10–15 kcal per 100 mL, so a stomach-full provides little energy. A 30-month-old needs about 1,000–1,200 kcal/day, of which complementary foods should provide 500–700 kcal alongside breastfeeding.
- Protein and micronutrients are almost absent. No pulse, milk, egg, fruit or green leafy vegetable in the past week means poor protein quality and low iron, zinc, calcium and vitamin A.
- Only two meals a day. At this age she needs 5–6 small meals, because her stomach capacity is small.
- On-demand breastfeeding at 30 months is displacing meals. Breast milk should continue up to two years but must not replace solid food.
- Repeated diarrhoea reduces absorption and appetite; the missed vitamin A dose and no deworming add to the risk.
Corrected plan
- Five to six meals: mashed rice with dal, khichdi with 1 teaspoon ghee, ragi porridge with milk, idli with sambar, mashed egg or curd, seasonal fruit, green leafy vegetables.
- Add 5 mL oil or ghee to each meal to raise energy density, and 1–2 teaspoons of roasted groundnut or sesame powder.
- Continue breastfeeding, but after meals rather than instead of them; responsive feeding with patience and no force.
- Give vitamin A as per the national schedule, deworm with albendazole 400 mg, check haemoglobin, and provide take-home ration from the anganwadi.
- Counsel on hand-washing and safe water to break the diarrhoea cycle.
3. Outline the follow-up plan, including when you would refer her, and explain why weighing alone would not have detected her main problem.

Follow-up plan
- Weigh monthly and plot on the growth chart; measure length every three months and MUAC at each visit.
- Expected catch-up gain is roughly 300–500 g per month in the first months; any loss or flat weight for two consecutive months is a warning.
- At each visit record appetite, illness, stool frequency, breastfeeding and actual meals eaten the previous day.
- Repeat haemoglobin after iron supplementation and check for anaemia, since sparse hypopigmented hair suggests micronutrient deficiency.
Referral criteria Refer to the nutrition rehabilitation centre or hospital if she develops bilateral pitting oedema, MUAC below 12.5 cm, weight-for-length below −3 SD, fails the appetite test, develops persistent diarrhoea, pneumonia, tuberculosis or any medical complication, or shows no weight gain after two months of good community management.
Why weight alone is inadequate Weight is a single number that mixes acute and chronic states. A stunted child can have a normal weight-for-age if she is relatively heavy for her short height, so the chronic deficit stays hidden. Conversely, a child with oedema from kwashiorkor may weigh more, not less. Age-specific weight-for-age cannot separate stunting from wasting, which need different responses: wasting needs urgent energy and protein, while stunting needs long-term dietary improvement, infection control and repeated growth monitoring. Only the combination of weight-for-age, length-for-age and weight-for-length tells you which problem you are treating.
