Which of the following is not a characteristic feature regarding protein energy malnutrition, marasmus?

Options

A. It is produced by a simultaneous deficiency of proteins and calories
B. it is found in infant less than a year of age
C. Patient shows wasting of muscles, thinning oflimbs, failure of growth and brain development.
D. Some fat is left under the skin of patient, extensive oedema and swelling of body parts are seen

Answer

To determine which of the following is not a characteristic feature of protein-energy malnutrition (PEM) specifically related to marasmus, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand Marasmus**:
- Marasmus is a form of protein-energy malnutrition that primarily results from a severe deficiency of both protein and calories. It is characterized by significant weight loss and muscle wasting.

2. **Evaluate Each Option**:
- **Option 1**: "It is produced by a simultaneous deficiency of proteins and calories."
- This statement is true. Marasmus occurs due to a lack of both proteins and calories.

- **Option 2**: "It is less than one year."
- This statement is also true. Marasmus is commonly observed in infants and young children, particularly those under one year of age.

- **Option 3**: "Patients show wasting of muscles, thinning of limbs, failure of growth, and brain development."
- This statement is accurate. These symptoms are characteristic of marasmus due to the severe malnutrition affecting growth and development.

- **Option 4**: "Some fat is left under the skin of the patient, extensive edema."
- This statement is false in the context of marasmus. In marasmus, there is typically a significant loss of subcutaneous fat and no extensive edema. Edema is more characteristic of kwashiorkor, another form of protein-energy malnutrition.

3. **Conclusion**:
- The option that is not a characteristic feature of marasmus is **Option 4**: "Some fat is left under the skin of the patient, extensive edema."

### Final Answer:
**Option 4** is not a characteristic feature regarding protein-energy malnutrition, marasmus.
