Define drawbacks of Nutritional status that assessed traditionally?

Nutritional status assessed traditionally with the use of anthropometric, biochemical clinical and dietary analysis has drawbacks. These include:

Data for elders is compared with normal values for younger persons.
Physical condition of elders makes some measurements difficult.
RDA's for those over 50 years of age not available.
Nutrient deficiency signs and symptoms are inappropriately attributed to normal aging.

Nutritional screening programmes, therefore, have been designed to assess for presence of malnutrition and some of the causes.
