The objective of this study was to investigate the association between the number of teeth and diet quality for Korean adult population.
Eligible participants in the Korea National Health and Nutrition Examination Survey during 2013-2015 were included (N = 11,461). Participants were grouped into three groups depending on the total number of teeth: 28 teeth, 20-27 teeth, and 0-19 teeth. Diet quality was defined using the Korean Healthy Eating Index (KHEI) by 24 -h recall methods. Univariate and multivariate regression analyses were applied controlling for age, income, education, smoking, diabetes mellitus, obesity, and hypertension.
In fully adjusted models, each tooth showed an increased KHEI score by 0.133 score and 0.150 score in males and females, respectively (p < 0.001 for all). The KHEI scores of participants with 0-19 and 20-27 teeth were 2.357 and 0.810 lower in males than those with 28 teeth (p = 0.001). The KHEI scores for females with 0-19 and 20-27 teeth were 3.008 and 1.223 lower than those with all teeth (p < 0.001). Considering KHEI 14 components, there was a clear association between the components and the number of teeth in females and males.
The results found a positively significant association between the number of teeth and diet quality in a nationally representative sample of the Korean adult population.
本研究旨在探讨韩国成年人群中牙齿数量与饮食质量之间的关系。
本研究纳入了 2013-2015 年韩国国家健康与营养调查中符合条件的参与者（N=11461）。参与者根据总牙齿数分为三组：28 颗牙齿、20-27 颗牙齿和 0-19 颗牙齿。采用 24 小时回顾法，使用韩国健康饮食指数（KHEI）来定义饮食质量。采用单变量和多变量回归分析控制年龄、收入、教育、吸烟、糖尿病、肥胖和高血压等因素。
在完全调整的模型中，男性和女性每颗牙齿的 KHEI 评分分别增加 0.133 分和 0.150 分（均<0.001）。男性中 0-19 颗和 20-27 颗牙齿的 KHEI 评分分别比 28 颗牙齿低 2.357 和 0.810 分（p=0.001）。女性中 0-19 颗和 20-27 颗牙齿的 KHEI 评分分别比所有牙齿低 3.008 和 1.223 分（p<0.001）。考虑到 KHEI 的 14 个组成部分，在男性和女性中，牙齿数量与饮食质量之间存在明显的关联。
本研究结果表明，在韩国成年人群的代表性样本中，牙齿数量与饮食质量之间存在正相关关系。
