摘要
目的:探讨健康饮食指数2015(HEI-2015)与牙周炎患病率的关联性。方法:基于NHANES数据库公共数据,纳入含饮食数据、牙周检查及混杂因素信息的受访者,通过加权计算构建基线模型。采用多变量逻辑回归分析HEI总分及子项目与牙周炎的关系,并按性别、年龄分层;进一步应用限制性立方样图分析非线性关系,划分HEI总分阈值并进行分段回归。结果:共纳入20356名参与者,总蔬菜、全果、总果、钠盐摄入量与牙周炎风险呈负相关(P<0.05),加工谷物摄入呈正相关(P<0.05)。HEI总分与牙周炎患病率呈U型曲线,低于拐点时负相关显著(P<0.05),高于拐点则无关联。结论:HEI-2015与牙周炎存在复杂关联,特定饮食项目具有保护作用,总分与疾病呈非线性U型关系,为个性化膳食干预提供依据。
Objective:To investigate the association between the Healthy Eating Index 2015(HEI-2015)and periodontitis prevalence.Methods:Based on publicly available data from the National Health and Nutrition Examination Survey(NHANES),participants 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 20356 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.
