“…From these it became apparent that the cause of the anaemia was usually iron deficiency associated with menorrhagia (cf. Elwood, Rees & Thomas, 1968). A11 subjects had normal chest X-rays and lung function and were free from airway obstruction.…”

1.Measurements of transfer factor and sub-maximal exercise ventilation and cardiac frequency have been made on twenty women with iron-deficiency anaemia (Hb 8-9 g/100 ml) before and after 'treatment' with iron or placebo tablets and on control subjects.2. The exercise ventilation, cardiac frequency and oxygen uptake were independent of haemoglobin concentration but the transfer factor was lower in the test than in control subjects and was increased by iron but not by placebo treatment. The results support the validity of the reaction-rate data for carbon monoxide with oxyhaemoglobin of Roughton & Forster (1957) despite evidence to the contrary from other studies.3. In interpretation of sub-maximal exercise ventilation and cardiac frequency in iron-deficiency anaemia no allowance need be made for variation in haemoglobin concentration in the range 8-15 g/lW ml. For transfer factor a correction should be made by using a variant of the relationship of Roughton & Forster (1957).Iron-deficiency anaemia is usually evidence for decrease in total body haemoglobin and its subdivisions, including the amount of haemoglobin in pulmonary capillaries. The latter influences directly the overall pulmonary reaction rate for carbon monoxide with oxyhaemoglobin (Roughton & Forster, 1957); thus in anaemia the ability of the lung to absorb carbon monoxide and oxygen from the air and of the circulation to deliver oxygen to the muscles are both decreased.The contribution to gas exchange may be studied by measurement of the transfer factor (diffusing capacity) for carbon monoxide (TI).

“…We have tried to evaluate the relationship between dietary intake of iron and circulating haemoglobin in a community sample of subjects. In menstruating women we found that menstrual iron loss had an overwhelming effect [Elwood et al, 1968b]. In older women (50-64 years) the association between dietary intake and circulating haemoglobin is much more obvious and can best be summarized by the regression equation:…”
