Abstract

Purpose: To investigate the relationship between the consumption of live microbes in the diet and adult periodontitis.

Materials and methods: Utilising data from the National Health and Nutrition Examination Survey (NHANES) spanning 1999-2004 and 2009-2014, 16,600 adults who underwent 24-h face-to-face dietary recall and oral health examinations were identified. Dietary live microbe intake was categorised into low, medium, and high levels. To examine the relationship between different levels of dietary live microbe intake and periodontitis, we employed logistic regression, subgroup and restricted cubic spline models.

Results: Upon comprehensive covariate adjustment, low dietary live microbe intake (104 CFU/g) demonstrated a positive association with periodontitis prevalence, while medium intake (104 to 107 CFU/g) showed a negative association. Conversely, no significant associations were observed between high dietary live microbe intake (>107 CFU/g) and periodontitis. Restricted cubic spline analysis confirmed a linear association between low dietary live microbe intake. Moreover, a U-shaped dose-response relationship was identified between medium dietary live microbe intake and periodontitis prevalence.

Conclusions: Moderate intake of medium live microbe food may be more conducive to avoiding the occurrence of periodontitis.

成人饮食中活微生物摄入与牙周炎之间的关系：来自NHANES的证据。

目的：探讨饮食中活菌摄入与成人牙周炎的关系。材料与方法：利用1999-2004年和2009-2014年国家健康与营养调查（NHANES）的数据，对16600名成年人进行了24小时面对面的饮食回忆和口腔健康检查。饮食中活微生物的摄入量被分为低、中、高水平。为了检验不同水平的饮食活微生物摄入量与牙周炎之间的关系，我们采用了logistic回归、亚组和限制三次样条模型。结果：经综合协变量调整，低饮食活微生物摄入量（104 CFU/g）与牙周炎患病率呈正相关，而中等摄入量（104 ~ 107 CFU/g）与牙周炎患病率呈负相关。相反，高饮食活微生物摄入量（100 ~ 107 CFU/g）与牙周炎之间没有显著关联。限制三次样条分析证实了低饮食活微生物摄入量之间的线性关联。此外，在中等膳食活微生物摄入量与牙周炎患病率之间确定了u型剂量-反应关系。结论：适量摄入中等活菌食品可能更有利于避免牙周炎的发生。
