Gut microbiome-based interventions for the management of obesity in children and adolescents aged up to 19 years
Abstract
BACKGROUND: The epidemic of overweight and obesity affects more than 390 million children and adolescents aged 5 to 19 years and 37 million children under five years of age. Overweight and obesity are associated with both short- and long-term consequences, including chronic inflammation, metabolic diseases, as well as alterations in the gut microbiome composition. Gut microbiome-based approaches may impact microbiome-related metrics such as diversity or the abundance of intestinal bacteria, which may be linked to obesity-related outcomes. However, evidence regarding the effect of gut microbiome-based interventions for the management of obesity is limited.
OBJECTIVES: To assess the effects of gut microbiome-based interventions in the management of overweight or obesity in children and adolescents in all their diversity aged 0 to 19 years.
SEARCH METHODS: We searched CENTRAL, MEDLINE, CINAHL, Web of Science Core Collection, BIOSIS Previews, Global Index Medicus (all regions), IBECS, SciELO, PAHO, PAHO IRIS, WHO IRIS, WHOLIS, Bibliomap, TRoPHI as well as ICTRP Search Portal and ClinicalTrials.gov. The date of the last search for all databases was 24 January 2025. We did not apply any language restrictions.
SELECTION CRITERIA: We included randomised controlled trials that evaluated gut microbiome-based interventions [i.e. prebiotics, probiotics, synbiotics, short-chain fatty acids (SCFAs), and faecal microbiota transplantation (FMT)] compared to standard-of-care, placebo, or…
