唾液微生物组、社会经济地位和认知表现：三角关系。

Research increasingly demonstrates that endogenous bacterial communities (microbiomes) are associated with both cognitive functioning and socioeconomic status (SES). In this study, we used a metagenomics approach to characterize oral microbiome diversity in Hispanic and African American children aged 6-16 years. We examined how microbiome composition and SES were related to cognitive performance, as assessed by the Wechsler Intelligence Scale for Children (WISC). Our findings indicate that SES and the microbiome contributed complementary, comparably sized influences on cognitive functioning. T
