Abstract
Presents a method to estimate a cutoff for hemoglobin concentration appropriate for estimating the prevalence of iron deficiency anemia in poor Jamaican girls 13-14 years of age. Iron deficiency was determined from a three-variable model of iron status (serum ferritin, erythrocyte protoporphyrin, and mean corpuscular volume). The most appropriate hemoglobin cutoff was considered the one that minimized misclassification of iron deficiency: that yielding the maximum kappa coefficient for correctly classifying iron deficiency between 100 and 120 g/L, at 1-g/L intervals. By using this method, a hemoglobin cutoff and the other indicators were used to estimate prevalences of iron deficiency and iron deficiency anemia in the Jamaican girls: 7.6 percent and 4.3 percent respectively. This approach should be appropriate for determining hemoglobin cutoffs for iron deficiency anemia in other populations.....
