What this trial studies

This cohort study investigates the changes in breastmilk composition during the first six months after the birth of Chinese infants. It aims to explore the relationship between breastmilk composition, maternal gut microbiome, and lifestyle factors such as diet, feeding practices, and physical activity, alongside the health and gut microbiome of the infants. The study will involve healthy mothers who intend to breastfeed and their infants, collecting data through observational methods without any interventions.

Who should consider this trial

Good fit: Ideal candidates include generally healthy Chinese mothers aged 18 and above who intend to breastfeed and their healthy term infants.

Not a fit: Patients who may not benefit include those with significant health issues, illegal drug use, or those unable to comply with the study protocol.

Why it matters

Potential benefit: If successful, this study could provide insights into optimizing breastfeeding practices and improving health outcomes for infants.

How similar studies have performed: While there have been studies on breastmilk composition, this specific focus on the maternal gut microbiome and lifestyle factors in a Chinese population is relatively novel.
