NCT04434027

Brief 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. 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.

Sampling MethodProbability Sample
Study Population

Normal, overweight or obese (\>25 BMI kg/m2) non-diabetic Hispanic mothers (18-59yrs) and their infants (\<1-36 months) from Los Angeles, CA.

You may qualify if:

  • Mothers who self-identify as Hispanic
  • Mothers who have or have had singleton births
  • Mothers will be recruited prior to their infant's birth or up to 1-month postpartum
  • Mothers must be able/willing to understand the procedures of the study, and must be able to read English or Spanish at a 5th grade level

You may not qualify if:

  • Physician diagnosis of a major medical illness (including type 1 or type 2 diabetes) or eating disorder in mothers
  • Physical, mental, or cognitive issues that prevent participation
  • Chronic use of any medication that may affect body weight or composition, insulin resistance, or lipid profiles
  • Current smoking (more than 1 cigarette in the past week) or use of other recreational drugs
  • Clinical diagnosis of gestational diabetes
  • Pre-term/low birth weight infants, or diagnosis of any fetal abnormalities
  • Mothers less than 18 years of age at the time of delivery will not be eligible as to avoid potential confounding from those subjects who might still be completing adolescent growth
