Purpose : Iron deficiency, particularly iron deficiency anemia(IDA) often not only decreases athletic performance but also impairs immune function and leads to other physiologic dysfunctions. This study was designed to assess and compare iron status and the IDA prevalence in female adolescent athletes with those of general adolescent students.
Methods : Physical measurements and hematologic examinations were performed for adolescent female runners(n=32), non-runner athletes(n=78) and apparently healthy students(n=511). Iron deficiency was defined as a serum ferritin concentration <12 ng/mL. The diagnosis of IDA was established when hemoglobin level <12 g/dL was associated with ferritin <12 ng/mL and/or transferrin saturation <16%.
Results : The prevalence of ID in the runners’ group(40.6%) was significantly higher than that of the non-runner athletes’ group(23.1%) and the control group(25.4%). The prevalence of IDA in the runners’ group was 31.3%, which was significantly higher than that of the non-runners’ group and the control group(7.7% and 16.4%, respectively).
Conclusion : The prevalence of IDA of Korean adolescent females was relatively high, especially, in female adolescent runners. Screening for anemia and iron status is warranted. It is important to measure for iron nutrition and to enforce effective nutritional education in these groups. (Korean J Pediatr 2004;47:1041-1046)
