Study IDST000957
Study TitleGlobal metabolomics of human milk fractions
Study Typecross sectional
Study SummaryPediatric obesity has more than doubled in children and tripled in adolescents over the past 30 years. Recent findings demonstrate that differences in energy harvesting bacteria promote obesity in the host and appear to be influenced by early life factors such as mode of delivery, maternal obesity, and breastfeeding. The goal of this proposal is to investigate how human milk impacts the infant gut microbiome during the first 12-months of life and identify the microbe-host interactions that mediates the protective role of breastfeeding on infant adiposity. The results of this exploratory study will characterize factors that influence microbial transmission between mothers and offspring and identify human milk compounds that stabilize a healthy infant microbiome with potential to reduce pediatric obesity.

Collection:

Collection ID:CO000990
Collection Summary:mothers will arrive in a fasted state in the morning and complete an infant feeding questionnaire as described previously (Lemas et al. 2016). Mothers will then pump ~30mL human milk (HM) into polypropylene vials and stored at -80ºC.
Sample Type:Human Milk

Treatment:

Treatment ID:TR001010
Treatment Summary:human milk samples were fractionated (fat and skim) using centrifugation and whole milk samples wer snap frozen at -80c.
