numerous measurements, the two most cormon are triceps skinfold and
subscapular skinfold. They measure the thickness of the fat tissue,
providing insight into the degree of calorie deficiency. With calipers,
the triceps skinfold is taken at the same point as the arm circumference
(described above), whereas the subscapular is taken at a point beneath
the inferior angle of the scapula (on the back). Through a simple
adjustment, the lean muscle circumference can be calculated, thus indi-
cating the level of protein sufficiency (Multiply the triceps skin-
fold measurement by pi and, then, subtract the product from the arm
circumference value; the result is the adjusted lean muscle circumfer-
ence.) Jelliffe and Jelliffe (1979) note that because there is such
a good correlation between AC and muscle circumference there is no need
to calculate the muscle circumference, particularly for field purposes.
Though blood profiles are used primarily to determine the adequacy
of nutritional intake, they also point out certain aspects of nutrition-
al status. The most common blood test examines hemoglobin content which,
if found below the normal range, reveals iron deficiencies in the diet.
There is also an assay for blood protein albumin which is a simple and
effective means for estimating protein intake, and, an estimate of the
level of dietary carbohydrates can be made through quantitating the
blood sugar level. While these tests are best used to give a general
idea of the level of nutrient intake, they also can be used as general
indicators of nutritional status in that they reflect chronic malnutri-
tion. Since, given nutrient intake deficiencies, the nody will draw on
reserves until depletion, lowered blood indicator levels reflect a
nutritional state that is chronically taxed. However, the degree or
