Short Term Response of Breast Milk Micronutrient Concentrations to a Lipid

Status Completed

Clinical Trial Summary

Research goals include evaluating the relative impact of maternal nutritional status versus recent dietary intake on breast milk micronutrient composition, and evaluating the impact of a maternal lipid based nutrient supplement (LNS) on breast milk micronutrient composition.

Clinical Trial Description

The study includes a cross sectional and an interventional component. Maternal dietary intake and nutritional status will be compared to breast milk micronutrient composition in a cross sectional manner.

The short term effect of maternal dietary intake on breast milk micronutrient composition will be examined using an intervention with a controlled diet and LNS. Infants will be test-weighed during the LNS intervention in order to calculate the infant micronutrient intake from the control and LNS intervention days.

Mother-infant dyads will be recruited into the study and the order in which they will receive the 3 treatments will be randomized. All mothers will receive all treatments.

The mothers will be invited to the clinic on 4 separate occasions. During the first study visit, maternal blood will be collected, anthropometric indices will be assessed, and food frequency and demographic characteristic surveys will be administered. During the 2-4 visits, the LNS intervention will take place. Mothers will arrive at the clinic fasted, and a fasted milk collection will occur. Subsequently, mothers will be provided 3 meals based on local foods with low-nutrient density. Milk will be collected for 8 hours at each infant feed (ad libitum). A 24 hour dietary recall will be conducted. Mothers will receive 1) no LNS, 2) A single dose of LNS with breakfast, or 3) A single dose of LNS split into 3 parts with their meals throughout the day. Infants will be test weighed before and after each feed to calculate their nutrient intake from breast milk and the impact of the different supplementation schemes on their nutrient intake. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
