The Dietary Index for Gut Microbiota and Live Microbe Intake in Relation to Visceral Fat Obesity: Evidence From NHANES With Vitamin D as a Mediator.

ABSTRACT: While the gut microbiota plays a critical role in host metabolism, epidemiological evidence linking microbiota-targeted dietary patterns to visceral fat obesity (VFO) remains limited. Using data from 8080 adults aged 20-59 years participating in the National Health and Nutrition Examination Survey (NHANES) 2011-2018, we examined the associations of the Dietary Index for Gut Microbiota (DI-GM) and dietary live microbe intake with visceral fat area (VFA) and VFO, and further explored the potential mediating role of serum vitamin D. Multivariable linear and logistic regression models were applied to assess associations with VFA and VFO, respectively, with restricted cubic spline analyses (RCS) used to evaluate potential non-linear relationships. Higher DI-GM quartiles were significantly assoc
