About this study

Breast milk is considered the gold standard for infant nutrition thanks to its ability to provide adequate nutrition and a high amount of protective factors for the baby's health. According to the guidelines of the World Health Organization (WHO), exclusive feeding with breast milk should be conducted until the end of 6 months of life and should be continued in the following months with the simultaneous introduction of complementary foods. Several evidence demonstrates that breast milk intake is associated with positive health outcomes, both during infancy and later in the life. Given the protective role of breast milk for the health of the child and the future adult, studying its content is of fundamental importance to have an integrated vision of the biological effects of its components on the child health, and of the factors that are able to modulate its composition. The "Building a Deeper Knowledge on Breast Milk Composition" (BuKoBc) project was designed to study the content of human milk in its entirety and at different times during the feeding and day, also in relation to environmental factors capable of modulating its composition. The results of this study may provide data on optimal reference ranges for nutrient intake in breastfed infants and may provide guidance for defining optimal nutrient intake for infants who cannot be breastfed. Furthermore, the in-depth study of the environmental factors capable of influencing the composition of breast milk will allow the development of nutritional intervention strategies for the breastfeeding mother in order to positively modulate the composition of her milk.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To analyze the contents of breast milk completely and at different times during the feeding and during the day.

    6 milk samples of at least 5 ml each will be collected at the beginning and end of the morning feeding, at the beginning and end of the afternoon feeding, and at the beginning and end of the evening feeding.

    Measured: 36 months

  2. Nutritional composition analysis (macro and micronutrients)

    Mass spectrometry analyzes will be performed.

    Measured: 36 months

  3. Metagenomic analysis

    Shotgun analysis will be performed.

    Measured: 36 months

  4. Metabolomics analysis

    Mass spectrometry analyzes will be performed.

    Measured: 36 months

  5. MicroRNA analysis

    TaqMan MicroRNA Assays will be adopted.

    Measured: 36 months

  6. Compounds derived from ultraprocessed foods and from packaging analyses

    Mass spectrometry analyzes will be performed.

    Measured: 36 months

Secondary outcomes (1)
  1. To analyze the environmental factors capable of modulating the composition of breast milk

    Maternal energy and nutrient intake, maternal ultra-processed food intake, level of adherence to the Mediterranean Diet, nutritional status, body composition, lifestyle, level of physical activity, level of education, intake of medications, food supplements, prebiotics, probiotics and synbiotics, consumption of alcohol, caffeine and tobacco will be evaluated.

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

An observational study of Breastfeeding, run by Federico II University at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To analyze the contents of breast milk completely and at different times during the feeding and during the day. (time frame: 36 months). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Sep 2026.
