简要总结
The overall objective of this project is to understand how consuming a prescribed diet of different infant foods (which may contain cereals,fruits, vegetables, meats, dairy) during the time of early complementary feeding (~5 to 12 months) in breastfed infants has on growth trajectories, neurodevelopment and sleep patterns in relation to gut microbiota, compared with a traditional diet that is usually provided in the home to infants.
The three primary aims include:
Aim 1: Identify the effects that the prescribed early complementary feeding specific study diet has on growth trajectories in breastfed infants.
Aim 2: Identify whether the relationship between the prescribed early complementary feeding specific study diet and growth is mediated by gut microbiota.
Aim 3: Characterize infant neurodevelopment and sleep patterns.

入选标准
- •Full term: gestational age > 37 weeks
- •Exclusively breastfed (< 2 weeks of cumulative formula exposure). Any formula consumption on a given day is considered one day of formula exposure. During the intervention, if the participant receives more than 50% of the liquid diet from infant formula, s/he will be excluded from the study.
- •Maternal conditions such as gestational diabetes mellitus, preeclampsia, multiple pregnancies are acceptable.
排除标准
- •Large for gestational age or small for gestational age
- •Antibiotic use from birth to the time of enrollment
- •Documented food allergies
- •Previous complementary food exposure
