Area of Science:

  • Pediatrics
  • Biomedical Engineering
  • Nutritional Science

Background:

  • Accurate measurement of maternal milk intake is crucial for assessing infant growth and nutritional status.
  • Existing methods for measuring milk intake may have limitations in precision or practicality.

Purpose of the Study:

  • To evaluate the methodological aspects and validity of the deuterium dilution technique for determining maternal milk intake in infants.
  • To establish the time frame for achieving isotopic equilibrium after deuterium administration.

Main Methods:

  • The deuterium dilution technique was applied to 2-3-month-old infants.
  • Isotopic equilibrium was assessed after administering a 16.5% deuterium solution.
  • Liquid intake was compared between the deuterium method and direct recording in infants recovering from undernutrition, using body water estimated by the Friis-Hansen formula.

Main Results:

  • Isotopic equilibrium was reached within 6-8 hours post-administration of the deuterium solution.
  • A good correlation was observed between the deuterium dilution method and direct recording of milk intake.
  • The Friis-Hansen formula provided reliable estimation of infant body water for the calculations.

Conclusions:

  • The deuterium dilution technique is a valid and valuable method for measuring maternal milk intake in infants.
  • This isotopic method offers a reliable alternative to current techniques for assessing infant nutrition.
  • The findings support the use of deuterium dilution in pediatric nutritional research and clinical practice.
