Nutritional Assessment
Pediatric nutritional assessment for MBBS: anthropometric indices, dietary recall, macronutrient energy values and diet planning, mapped to NMC codes PE9.1 to PE9.7.
This chapter covers age-related nutritional needs and the tools for assessing and classifying nutritional status, including anthropometric indices, dietary recall and calorie calculations. It teaches how to identify the gap between requirement and intake and plan an appropriate diet in health and disease.
High-yield: Nutritional Assessment
- Exclusive breastfeeding is advised for the first six months, complementary feeding from six completed months, and adolescents need extra iron, calcium and protein.
- Height-for-age identifies stunting, weight-for-height identifies wasting and weight-for-age identifies underweight.
- Body mass index (BMI)-for-age is used for thinness or obesity in older children, and mid-upper arm circumference is used for field triage of acute malnutrition.
- Nutrition status should never be classified from weight alone; ask weight for what age, height for what age, weight for what height and the trajectory.
- The macronutrient energy factors are 4 kilocalories per gram for carbohydrate, 4 for protein and 9 for fat.
- In Indian diets the largest hidden calorie sources are frying oil, ghee, sweet drinks, packaged snacks and large cereal portions.
- A dietary recall should document the time, item, amount, preparation, additives, caregiver and whether the meal was completed.
- Normal diet is never acceptable documentation in a nutrition case; a structured 24-hour recall is required.
- The skill answer format for a nutrition case is: requirement, intake, gap, reason, food plan and monitoring.
- Age-related calorie requirements are increased in illness, so requirement and actual intake must be compared to identify the gap.
- Wasting (low weight-for-height) reflects acute malnutrition, while stunting (low height-for-age) reflects chronic malnutrition.
- Mid-upper arm circumference is a simple, age-independent field tool for identifying acute malnutrition in 6 to 59 month children.
- Diet planning should include a calorie target, protein and micronutrient priorities, a household meal plan, disease modification and monitoring.
- Nutritional assessment combines anthropometry, dietary history and clinical signs of deficiency rather than any single measure.
Anthropometric indices and their meaning
- **Height-for-age:** Low value indicates stunting (chronic malnutrition).
- **Weight-for-height:** Low value indicates wasting (acute malnutrition).
- **Weight-for-age:** Low value indicates underweight.
- **MUAC:** Mid-upper arm circumference for field triage of acute malnutrition.

- **PE9.7:** Plan an appropriate diet in health and disease
Frequently Asked Questions
Which anthropometric index shows stunting versus wasting?
Height-for-age identifies stunting, which reflects chronic malnutrition, while weight-for-height identifies wasting, which reflects acute malnutrition. Weight-for-age identifies underweight and BMI-for-age screens for thinness or obesity in older children.
What are the energy values of macronutrients?
Carbohydrate and protein each provide 4 kilocalories per gram and fat provides 9 kilocalories per gram, which is why frying oil, ghee and packaged snacks are the largest hidden calorie sources in Indian diets.
How should a dietary recall be documented?
A 24-hour dietary recall should document the time, item, amount, method of preparation, additives, the caregiver and whether the meal was completed. The phrase normal diet is never acceptable documentation.
What is the structure of a good nutrition assessment answer?
A complete answer states the requirement, the actual intake, the gap between them, the reason for the gap, a practical household food plan and a monitoring plan, rather than only quoting a formula.
