What this trial studies

This observational cohort study investigates the differences in breast milk microbial profiles from mothers in Malaysia and China, focusing on how these differences may influence infant health outcomes such as temperament, gastrointestinal symptoms, eczema, and asthma. Pregnant women will be followed from their first trimester through the first year of their infant's life, with multiple data collection points to assess the impact of gut microbiota on development. The study aims to enhance understanding of the prenatal and postnatal factors that contribute to healthy gut microbiome development in infants.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women aged 18 to 45 who are in their first trimester and plan to attend post-natal check-ups for at least one year.

Not a fit: Patients who may not benefit from this study include those with immune deficiencies, multiple pregnancies, or congenital abnormalities in their newborns.

Why it matters

Potential benefit: If successful, this study could provide insights into how maternal health and diet influence infant gut health, potentially leading to improved health outcomes for infants.

How similar studies have performed: While there have been studies on gut microbiota and infant health, this specific cohort comparison between Malaysia and China is novel and has not been extensively tested.
