ABSTRACT
A method is presented to estimate a cutoff for hemoglobin concentration appropriate for estimating the prevalence of iron deficiency anemia in poor Jamaican girls 13-14 y 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 of 107 g/L was considered most appropriate. This cutoff and the other indicators were used to estimate prevalence of iron deficiency and iron deficiency anemia in the Jamaican girls 7.6% and 4.3%, respectively. This approach should be appropriate for determining hemoglobin cutoffs for iron deficiency anemia in other populations.
