General linear models were used to evaluate the relation between changes in iron status biomarkers and work efficiency. RESULTS The Fe-Bean intervention had significant positive effects on hemoglobin, serum ferritin, and body iron stores but did not affect work efficiency. However, 18-wk change in hemoglobin was positively related to work efficiency at 40 W in the full sample (n = 119; estimate 0.24 g/L; 95% CI 0.01, 0.48 g/L; P = 0.044) and among women who were anemic (hemoglobin less then 120 g/L) at baseline (n = 43; estimate 0.64
