Black & White Used the sample of women of child-bearing age from
the Second National Health and Examination Survey to examine the
relationship between hemoglobin and iron status for blacks and
whites. Black women had a significantly lower mean hemoglobin
value (126 +/- 12 g/L) than white women (134 +/- 11 g/L).
Evaluation of the screening performance of hemoglobin found that
race-specific anemia criteria (10 g/L difference) yielded a
comparable sensitivity and specificity in detecting iron
deficiency for both races. In contrast, a fixed anemia criterion
did not yield comparable screening performances for the two
races. This functional evaluation supports considering race-
specific anemia criteria for screening iron deficiency. Johnson-
