Increased Level of Serum Hepcidin in Female Adolescent Athletes
Abstract
Objective: To determine the serum hepcidin concentration and standard hematological parameters in a group of female adolescent athletes, compared with a group of nonathlete females. Design: A case–control study. Setting: A senior high school for athletes in Gothenburg, Sweden. Participants: All female athletes (70), at the school were offered to take part. Fifty-six athletes accepted. From a random sample of age-matched nonathletes, 71 students were recruited to the control group. Main Outcome Measures: Iron deficiency (ID) was determined by levels of serum iron, total iron-binding capacity, transferrin saturation (TS), and ferritin. Serum hepcidin was determined by a mass spectrometry method. All samples were taken at least 12 hours after training. Results: The main result was the finding of a significantly elevated serum hepcidin level in the athlete group, 4.7 nmol/L compared with 3.3 nmol/L (P < 0.001) in the nonathlete group. In the athlete group, the serum iron concentration was significantly lower, 14.0 μmol/L compared with 17.6 μmol/L (P = 0.003) in the nonathlete group. No difference was found regarding TS, total iron binding capacity, and ferritin. There was no difference in the occurrence of ID or iron deficiency anaemia (IDA). Conclusions: These findings show an increase in serum hepcidin in a large group of female athletes. The elevated hepcidin levels may affect the iron balance of the athletes, adding to the traditional explanation of dietary intake/iron loss balance.

In the citing paper
“In addition to insufficient intake, high-intensity sport can lead to ID through other mechanisms, such as increased iron demand, higher iron loss due to micro-trauma and ischemia of the gut, hemolysis, iron loss through increased sweating [12,18,25], and dysregulation of iron absorption and storage by elevated hepcidin levels post-exercise [26].”

“The effect of exercise on hepcidin influence the iron balance and makes it difficult to interpret the degree of contribution by each possible determinant of ID because hepcidin is the main regulator of iron absorption in the gut and of release from the macrophages.(3) We have previously used serum ferritin ,16 mg/L as…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
