Aim: Breastmilk calcium concentrations can vary between lactating women and over the lactation period. This study assessed breastmilk calcium concentrations among Palestinian lactating women.
Methods: The demographic and dietary variables of the lactating women were collected using a questionnaire. The women provided a sample of about 5 mL of breastmilk using hand expression. Breastmilk calcium concentrations were quantified using an inductively coupled plasma-mass spectrometric method.
Results: Breastmilk samples were taken from 240 lactating women. The mean breastmilk calcium concentration was 285.4 ± 115.1 mg/L. Lower breastmilk calcium concentrations were associated with age, lactating period, unemployment, dissatisfaction with income and insufficient consumption of vitamins and minerals.
Conclusion: Breastmilk calcium concentrations were affected by demographic variables of the lactating women and insufficient consumption of vitamins and minerals. The findings reported in this study are informative to healthcare providers and decision makers who might be interested in improving the health of lactating women and their infants.

Milk production during lactation places a high demand for calcium that is fulfilled both from maternal bone resorption and diet. While it is known that mammary gland-derived PTHrP drives bone resorption during lactation, the impact of postpartum estrogen loss on bone has been unclear. We used a case-control study design to test the effect of estrogen loss in lactating mice.

The aim of our study was to show the presence of neurotrophic factors in breast milk that have a significant impact on neurocognitive development of children aged two years and beyond. Mothers expressed at least 5 mL of breast milk into sterile containers when their children 18, 24, and ≥ 25 months of age, and then specimens were transferred to Eppendorf tubes and stored at -20 °C. One day before the analysis, specimens were kept at +4 °C and then thawed at room temperature to prepare them for analysis.
