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 (01 years old, 12 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.
