[Composition of gut microbiota and characteristics of virulence factors genes in overweight or obese children and their relationship with liver metabolic inflammation].

Overweight or obese children exhibited elevated liver metabolic-inflammatory markers compared to their normal-weight counterparts. Notably, obese children demonstrated gut microbiota dysbiosis accompanied by enrichment of virulence factor genes, which may promote liver metabolic inflammation through pathways such as lipopolysaccharide biosynthesis.
