Lactoferrin was measured in breast milk from Aboriginal and non-Aboriginal Australian women using an enzyme immunoassay. There was no diurnal variation in lactoferrin concentration or change in concentration between the beginning and end of a feed. Lactoferrin levels were significantly higher in the first 15 days postpartum than in the period after the 15th day. Regression analysis showed that in milk from Aboriginal women less than 15 days postpartum, higher concentrations of lactoferrin were associated with weight for height (WFH) greater than 90% and with increased parity. Comparable data were not available for Caucasian women. For Aboriginal and Caucasian women more than 15 days postpartum, lactoferrin concentrations were higher in women greater than 90% WFH. Other variables, such as parity, were not significant in the regression.
采用酶免疫测定法对澳大利亚原住民和非原住民女性的母乳中的乳铁蛋白进行了检测。乳铁蛋白浓度不存在昼夜变化，且一次喂奶开始和结束时的浓度也无变化。产后15天内乳铁蛋白水平显著高于第15天之后的时期。回归分析表明，产后不到15天的原住民女性的乳汁中，较高浓度的乳铁蛋白与身高体重比（WFH）大于90%以及产次增加有关。白种女性没有可比较的数据。对于产后超过15天的原住民和白种女性，身高体重比大于90%的女性的乳铁蛋白浓度更高。其他变量，如产次，在回归分析中不显著。
