Test to assess PEM in children in early stages is by
Answer: B
Protein energy malnutrition in children is assessed at an early stage by anthropometry, which means measuring weight, height or length, mid-upper arm circumference and head circumference and comparing them with reference standards. These changes in growth show up before clinical or laboratory signs. Biochemical and pathological tests detect established deficiency and are costly, so they are not used for early screening. Hence anthropometry is the correct answer, and 'none of the above' is wrong.
