Microbial dysbiosis in oral cavity determines obesity status in adolescents.

ABSTRACT: The prevalence of obesity is rapidly increasing among adolescents in Kuwait. The ecological and dynamic changes within the oral microbiota during this developmental stage remain elusive. This study aimed to investigate the impact of body mass index (BMI) on salivary microbiome diversity and composition in Kuwaiti adolescents by utilizing next-generation sequencing technologies. DNA was extracted from saliva samples of 62 Kuwaiti adolescents enrolled in the nationwide Kuwait Healthy Lifestyle Study, categorized as underweight, normal weight, overweight, and obese based on their BMI percentiles. The 16 S metagenomic profiling was performed to identify the key oral lineages and genera associated with obesity through comprehensive analysis involving taxonomic composition, co-occurrence network
