Brief summary
This study is planned to be recruited in two hospitals in South China, Zhujiang Hospital of Southern Medical University and Zhongshan Boai Hospital Recruit participants, plan to recruit obstetrics and child health departments in study hospitals, meet inclusion and discharge criteria 1\ 3 infants, a total of 360, recruited by Pearl River Hospital of Southern Medical University and Zhongshan Boai Hospital 180 people each.
Detailed description
This is a case-control study. By collecting fecal samples of infants and young children in the observation group and control group at different time points (0\ 1 years old, 1\ 2 years old, 2\ 3 years old), the intestinal flora of infants and young children was detected by 16S rDNA sequencing, and fecal calprotectin (CP) and secretory IgA (SIgA) were detected by ELISA. To study the effects of exposure factors on intestinal flora and immunity in offspring.
