This study introduces an automatic sampling shield for breast milk, which successfully collects samples for analysis without significantly impacting the infant's milk intake. While minor inaccuracies in fat content estimation were noted, the shield offers a practical method for breast milk composition research.

Area of Science:

  • Pediatrics
  • Human Nutrition
  • Biomedical Engineering

Background:

  • Accurate breast milk analysis is crucial for understanding infant nutrition.
  • Existing methods for collecting breast milk samples can be invasive or inconvenient.
  • Developing non-disruptive sampling techniques is essential for infant feeding research.

Purpose of the Study:

  • To evaluate the performance and usability of a novel automatic sampling shield for breast milk.
  • To assess the impact of the sampling shield on infant milk intake and nutrient absorption.
  • To determine the accuracy of breast milk composition analysis using samples collected by the shield.

Main Methods:

  • The automatic sampling shield was tested on 13 infants across multiple feeding sessions.

  • Shield performance was assessed based on sample collection rate, sample weight, and infant acceptance.
  • Fractional test-weighing and mathematical modeling were used to analyze sample proportionality and potential biases.
  • Infant milk intake was compared between feeding sessions with and without the shield.

    • Main Results:

    • The shield demonstrated high acceptance (96%) and successful sample collection (88%).
    • Collected samples (median 1.3 g) were adequate for biochemical analysis without compromising infant nutrition (median 4.3% of intake).
    • A slight disproportionality in sampling was observed, potentially overestimating fat intake by a mean of 2.6%.
    • Infant milk intake was reduced by 17% on average when using the shield, suggesting potential compensation.

    Conclusions:

    • The automatic sampling shield is a viable tool for collecting breast milk samples for compositional analysis.
    • The shield is well-accepted by infants and does not significantly deprive them of milk.
    • Further refinement may be needed to address minor sampling disproportionalities for precise nutrient assessment.
