Abstract

The purpose of the present study is to determine whether the circulating markers of iron status differ between vegetarian or non-vegetarian adolescent female high school cross-country runners. Fifteen non-vegetarian and six vegetarian female cross-country runners completed questionnaires used to obtain anthropometric data, health history, menstrual status, diet history and training history. Dietary intake was determined by self-report, using a food frequency questionnaire and a 3-day diet record. Blood samples were analyzed for serum iron, total iron binding capacity, serum ferritin, and transferrin saturation. No significant difference was found between vegetarians and non-vegetarians for serum iron or transferrin saturation. However, TIBC was significantly higher in vegetarians (p < 0.05). Ferritin was lower in vegetarians, trending toward significance (p < 0.10). Study results suggest the need for routine pre-season iron screenings as well as nutrition education, aimed at improving iron status for vegetarian and non-vegetarian adolescent female endurance athletes.
