Abstract:
We recently showed that the individual gut microbiome (GM) configuration in children and adolescents, together with long-term dietary habits, can predict the development of obesity. Here, we expanded our previous cohort to include 218 individuals and used 16S rRNA amplicon sequencing, shotgun metatranscriptomics, and a network approach to analyze fecal samples collected at a baseline survey and after a 4-year follow-up, investigating associations with health status, dietary intake, and other health-related behaviors. Our results showed that an unbalanced GM profile in children/adolescents, with few represented species, poor connectivity, and low transcriptional activity (especially in relation to molecular effectors that positively influence gut and immune health), combined with unhealthy behaviors (i.e., low-fiber diet and reduced physical activity), may favor the onset of obesity. This knowledge may pave the way for the development of adjunct GM-based precision intervention strategies aimed at rewiring microbial networks to promote long-term health.
