  1. Fulltext. Functional consequences of iron supplementation in iron-deficient female cotton mill workers in Beijing, China.

    Article - En anglais


    Eighty iron-deficient, nonpregnant female workers were randomly assigned to ferrous sulphate (60 or 120 mg Fe/d) or placebo treatment for 12 wk.

    Energy expenditure was estimated during 3 d by heart rate (HR) recording.

    Production efficiency (PE) was calculated as the ratio of productivity to energy expenditure.

    In the iron-treated group mean hemoglobin (Hb) increased from 114 to 127 g/L (P<0.001), mean serum ferritin increased from 9.7 to 30.0 mug/L (P<0.001), and mean free erythrocyte protoporphyrin decreased from 1.01 to 0.49 mumol/L (P<0.001).

    Mean HR at work decreased from 95.5 to 91.1 beats/min (P<0.001), which was inversely correlated with the change in Hb (r=-0.60, P<0.001).
