Trial summary

This study will investigate the effects of breastfeeding and breastmilk composition on infant gut microbiome development as well as obesity and cognitive outcomes. Breast milk contains certain natural sugars that can promote the growth of 'good' bacteria in the intestines and reduce the growth of harmful bacteria. Read more about this study

About this study

Official title: Mother's Milk Study: Determining the Impact of Human Milk Oligosaccharides (HMOs) on Healthy Infant Growth and Development

This study will investigate the effects of breastfeeding and breastmilk composition on infant gut microbiome development as well as obesity and cognitive outcomes. Breast milk contains certain natural sugars that can promote the growth of 'good' bacteria in the intestines and reduce the growth of harmful bacteria. The purpose of this study is to look at the effects of these natural sugars in breast milk on the infant's bacteria and the impact of this on development of obesity and cognitive outcomes by 2 years of age with plans for longer term follow up contingent upon funding.

Read the detailed description

This project will examine specific factors in breast milk that may impact infant's gut microbiome development, and thereby impact their adiposity and weight gain in early life. An important early-life experience that could meaningfully impact the development of the gut microbiome, as well as future obesity risk, is breastfeeding. Breast milk has been shown to contain certain macronutrients (human milk oligosaccharides; HMOs) that not only vary greatly among women, but recent studies suggest that these factors are significant predictors of infant weight gain and adiposity. Examining early onset obesity during infancy is important because accelerated weight gain and adiposity in the first few years of life are major predictors for later obesity, and because neuronal, metabolic, and gut microbiome systems are especially vulnerable by programming from nutritional and maternal factors during this stage of life.

This study will be conducted in Los Angeles. The investigators will recruit two-hundred-and-forty mother-infant pairs. Mothers and infants will be monitored during the first 36 months of life, with sampling of breast milk (while the mother is still breast feeding) and infant and maternal stool at 1, 6, 12, 18, and 24 months of age (or as close as possible to each month). Only an infant stool sample will be collected at 36 months of age. The main outcomes of this study will be infant body weight-for-length growth during this period, as well as body composition (fat and lean mass), which will be measured by skin-fold thickness using a caliber, height, weight, and waist circumference measurements at 1, 6, 12, 18, 24, and 36 months of infant age (or as close as possible to each month). The investigators will also assess maternal and infant diet using 24-hour recalls, and maternal feeding style and infant eating behaviors using questionnaires.

Questions about this trial

What is this clinical trial studying?

An observational study of Obesity, run by University of Southern California at 1 site in United States.

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 4 inclusion and 7 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 28 Mar 2025. 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 United States. 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?

Infant weight z-scores at baseline (time frame: Baseline). The study lists 32 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 28 Mar 2025.
