Dietary inflammatory index mediates the association between planetary health diet index and periodontitis.

ABSTRACT:

Background

With global shifts in diet and environment, understanding how dietary factors and inflammation affect oral diseases like periodontitis is essential for prevention. The Planetary Health Diet Index (PHDI) promotes a plant-based diet for both health and sustainability, while the Dietary Inflammatory Index (DII) measures a diet's inflammatory potential. This study examines the link between PHDI and periodontitis and assesses DII's moderating role.

Methods

This study conducted a cross-sectional analysis of 9,016 participants from the 2009-2014 NHANES database. We used subgroup analysis, restricted cubic splines (RCS), and multivariable logistic regression to investigate the association between PHDI and periodontitis prevalence. Additionally, mediation analysis was perf
