Study design:

Cohort study 

研究目的:

本项目旨在系统探索母亲孕期情绪、肠道菌群、代谢物、饮食多维因素对子代免疫的影响及其潜在机制。研究将综合分析多维因素的交互作用,明确其对子代免疫的协同或拮抗效应,为孕期健康管理及临床干预策略提供理论依据,最终促进母婴健康。  

Objectives of Study:

This project aims to systematically investigate the effects of maternal prenatal emotional status, gut microbiota, metabolites, and dietary factors on offspring immunity, as well as the underlying mechanisms. The study will comprehensively analyze the interactions among these multidimensional factors to elucidate their synergistic or antagonistic effects on offspring immune function. The findings are expected to provide a theoretical basis for optimizing maternal health management during pregnancy and developing targeted clinical intervention strategies, ultimately promoting maternal and child health.
