Non-pregnant women from the low socio-economic class were found to have significantly lower haemoglobin, plasma transferrin and retinol-binding protein concentrations than those from the upper classes. Pregnancy in these poor women resulted in a further significant lowering of these constituents. Children born to such mothers had significantly lower birthweights and plasma transferrin concentrations. A highly significant positive correlation was found between maternal serum transferrin concentration and birthweight, suggesting that this protein is a sensitive index of nutritional state in pregnancy.
研究发现，社会经济地位较低阶层的未孕女性，其血红蛋白、血浆转铁蛋白和视黄醇结合蛋白浓度显著低于较高阶层的女性。这些贫困女性怀孕后，这些成分会进一步显著降低。这类母亲所生的孩子出生体重和血浆转铁蛋白浓度显著较低。研究发现，母亲血清转铁蛋白浓度与出生体重之间存在高度显著的正相关，这表明该蛋白是孕期营养状况的一个敏感指标。
