Abstract:
Objective:To investigate the association between the Healthy Eating Index 2015(HEI-2015)and periodontitis preva-lence.Methods:Based on publicly available data from the National Health and Nutrition Examination Survey(NHANES),partici-pants with dietary data,periodontal examination results,and confounding factor information were included.A baseline model was constructed using weighted calculations.Multivariate logistic regression was employed to analyze the relationship between HEI total scores,subcomponents,and periodontitis,with stratification by gender and age.Restricted cubic spline analysis was further applied to explore nonlinear associations,identify HEI total score thresholds,and conduct piecewise regression.Results:A total of 20 356 participants were included.Intake of total vegetables,whole fruits,total fruits,and sodium showed significant negative correlations with periodontitis risk(P＜0.05),while processed grain consumption demonstrated a positive correlation(P＜0.05).The HEI total score exhibited a U-shape curve relationship with periodontitis incidence,with a significant negative correlation below the inflection point(P＜0.05)and no association above it.Conclusion:The HEI-2015 demonstrates a complex association with periodontitis,with specific dietary components exerting protective effects.The nonlinear U-shape relationship between the total HEI score and disease risk provides a basis for personalized dietary interventions.
