Breast-Milk Consumption of Healthy Full-Term Infants

AbstractObjectiveTo test equations for calculating infants’ energy requirements as a simple and reliable instrument for estimating the amount of breast milk consumed in epidemiological studies where test-weighing is not possible.DesignInfants’ energy requirements were calculated using three different equations based on reference data and compared with actual energy intakes assessed using the 3 d weighed dietary records of breast-fed infants from the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) Study.SettingA sub-sample of 323 infants from the German DONALD Study who were predominantly breast-fed for at least the first four months of life, and who had 3 d weighed dietary records and repeated body weight measurements within the first year of life.SubjectsHealthy, term infants breast-fed for at least 4 months, 0–12 months of age.ResultsThe overall differences between measured energy intake and calculated energy requirements were quite small, never more than 10 % of total energy intake, and smaller than the mean variance of energy intake between the three days of recording. The equation of best fit incorporated body weight and recent growth, while the worst fit was found for the equation not considering body weight.ConclusionsBreast milk consumption in fully and partially breast-fed infants can be reasonably quantified by calculating the infants’ individual energy requirements via simple equations. This provides a feasible approach for estimating infant energy intake in epidemiological studies where test-weighing of breast milk is not possible.

AbstractObjectiveTo investigate the prevalence and predictors of expressed breast-milk feeding in healthy full-term infants and its association with total duration of breast-milk feeding.DesignProspective cohort study.SettingIn-patient postnatal units of four public hospitals in Hong Kong.SubjectsA total of 2450 mother–infant pairs were recruited in 2006–2007 and 2011–2012 and followed up prospectively for 12 months or until breast-milk feeding had stopped.ResultsAcross the first 6 months postpartum, the rate of exclusive expressed breast-milk feeding ranged from 5·1 to 8·0 % in 2006–2007 and from 18·0 to 19·8 % in 2011–2012. Factors associated with higher rate of exclusive expressed breast-milk feeding included supplementation with infant formula, lack of previous breast-milk feeding experience, having a planned caesarean section delivery and returning to work postpartum. Exclusive expressed breast-milk feeding was associated with an increased risk of early breast-milk feeding cessation when compared with direct feeding at the breast. The hazard ratio (95 % CI) ranged from 1·25 (1·04, 1·51) to 1·91 (1·34, 2·73) across the first 6 months.ConclusionsMothers of healthy term infants should be encouraged and supported to feed directly at the breast. Exclusive expressed breast-milk feeding should be recommended only when medically necessary and not as a substitute for feeding directly at the breast. Further research is required to explore mothers’ reasons for exclusive expressed breast-milk feeding and to identify the health outcomes associated with this practice.

1. Mn and Cu intake and retention in twenty full-term infants and six preterm infants were studied on the basis of 72 h balances. The age of the infants was 2–16 weeks and the gestational age of the preterm infants (triplets) 34 and 36 weeks. Three nutrition schemes were pursued: breast-fed, formula-fed with unsupplemented adapted formula and formula-fed with trace element supplementation.2. The mean Mn concentration of all breast-milk samples (n 2339) was 6·2 μg/1. The two formulas had similar Mn concentrations (77 and 99 μg/1) but had different Fe, Cu (121 and 619 μg/1), Zn and I contents. The mean Cu concentration in mother's milk was 833 μg/1.3. The following mean daily Mn intakes and retentions (μg/kg) respectively were measured: breast-fed fullterm 1·06 (sd 0·43) and 0·43 (sd 0·65), formula-fed full-term 14·2 (sd 3·1) and 2·8 (sd 4·8), formula-fed preterm 15·0 (sd 2·2) and 0·06 (sd 5·87). The results for Cu were 114·5 (sd 22·3) and 88·0 (sd 46·5) μg/kg in breast-fed, 19–8 (sd 4·2) and 4·6 (-11·5–9·6) in the unsupplemented formula-fed and 106·4 (sd 18·9) and 55·5 (sd 20·3) in the supplemented formula full-term infant group. No significant influence of the trace element contents of the formulas on the relative retention of Mn or Cu was found.4. Young preterm infants, and to some degree young full-term infants, often had negative Mn balances caused by a high faccal excretion. The formulas with a Mn concentration below 100 μg/l gave a sufficient supply of Mn. Preterm infants fed on the unsupplemented formula had a marginal Cu supply and their first balances were negative (-3·8 (sd 1·8) μg/kg).5. In accordance with the estimated safe and adequate daily dietary intakes (recommended dietary allowances), formula-fed infants receive much more Mn than breast-fed infants and their absolute retention is higher.6. Cu from breast-milk had a significantly better biological availability than that from cow's milk formula. If retentions similar to those in breast-fed infants are intended, we conclude, therefore, that cow's milk formula should be fortified with Cu up to a level of at least 600 μg/l.
