We’re currently enrolling lactating individuals into the following studies:
Diversity of Human Milk & How It May Be Affected by Maternal Use of Antibiotics
Our team is examining the diversity of human milk by enrolling 480 nursing parents and their nursing infant who is less than 6 months old. Participation in this study includes phone interviews, self-collection of milk samples, self-collection of stool samples and skin swab samples from both the nursing parent and baby, self-collected samples from certain areas of the home, questionnaires about baby’s development, release of medical records, and weekly text messages inquiring about use of any prescription antibiotics and/or changes in nursing. Enrollment is open to persons residing in Southern California. See if you qualify.
From the responses to the weekly text messages, our second goal is to identify 40 nursing parents who are prescribed an antibiotic while they are still lactating, and to enroll them in additional follow-up activities. We will also identify and enroll two comparison groups: 20 parents who are prescribed an antibiotic but are no longer lactating, and 40 lactating parents/babies without antibiotic exposure. For all three of these groups, additional samples will be collected from the parent, the baby, and their home. The goal is to learn whether and/or how prescribed antibiotics that are taken by a lactating parent affects human milk, and whether they have any effect on a baby’s growth and development.
Our team is examining whether Motegrity® (prucalopride), a medication taken for the treatment of functional constipation in adults, can be found in human milk. We’re looking for lactating individuals who are currently taking Motegrity®. Participation in this research study includes phone interviews, self-collection of human milk samples at different time points over a 24-hour period before and after taking a dose, questionnaires about baby’s growth and development, and releasing baby’s medical records. Volunteers receive up to $125 for completing the study. See if you qualify.
Donate to the Human Milk Biorepository
Mommy’s Milk Human Milk Research Biorepository at UC San Diego is building a research database that will be used to evaluate human milk. As the first-ever human milk research biorepository in the nation, we are moving science forward through highly-trained researchers contributing to human milk breakthroughs and discoveries.
Since 2014, we have been collecting human milk samples and de-identified clinical data from lactating individuals across the U.S. These samples and data can be accessed by researchers to answer critical questions about human milk and its effects on infant and child health. Our biorepository depends on lactating parents providing a milk sample for future research projects. Did you know, one ounce of human milk can fuel 15 research studies!
