Abstract

<p>Objective: This study investigated the iron deficiency of female university students and clarified the erythrocyte-related test in the normal-ferritin group.</p><p>Methods: We examined the ferritin deficiency (ferritin <12 ng/ml) and erythrocyte-related tests of 177 adult female university students. Additionally, a dietary survey was conducted to explore the diet pattern of the low-ferritin group, which combined the ferritin-deficient and declined-ferritin groups (ferritin 12–25 ng/ml).</p><p>Results: The iron deficiency anemia incidence was 3.3%, and latent iron deficiency without anemia was 18.1%. The mean corpuscular hemoglobin (MCH) cutoff value of 28.6 pg, was 89.4% for sensitivity and 76.3% for specificity in screening for iron deficiency by erythrocyte-related test. The declined-ferritin group had significantly higher chicken intake than that of the ferritin-satisfied group. The ferritin-deficient group had a significantly lower ham intake and considerably higher western confectionery than that of the satisfied group. Comparing the low-ferritin group with that of the ferritin-satisfied group, greasy fish and natto intakes were significantly lower and coffee intake was significantly higher. The median iron intake per 1,000 kcal was 4.83 mg, 4.52 mg, and 4.42 mg in the satisfied, declined, and deficient groups, respectively; however, there was no significant difference.</p><p>Conclusions: Iron deficiency was found in 21.4% of female university students. As MCH of 28.6 pg was used as the cutoff value, iron deficiency could be screened with high sensitivity and specificity. However, the low-ferritin group consumed significantly more western confectionery and coffee; therefore, their diet pattern could not be well balanced.</p>
