The prevalence of iron deficiency was deter mined in Göteborg, Sweden, in a sample of 15- to 16-y-old girls (n=220) and boys (n=207) using serum ferritin (SF).
In a recent study in women on the relationship between SF and stainable bone marrow iron, it was established that at a cutoff value for SF of <16 mug/L in 75% of women with no iron stores SF concentration was below this value (sensitivity 75%), whereas in 98% of iron-replete women it was above this cutoff value (specificity 98%). The present study showed that in 40% of the girls and 15% of the boys SF was below this cutoff value, indicating iron deficiency.
Low SF concentration was associated with significant decreases in transferrin saturation, Hb concentration, mean corpuscular Hb, and mean corpuscular volume.
