The aim of this cross-sectional study was to investigate the relationship of oral health status defined on the basis of presence of posterior occluding pairs (POPs) and adequacy of removable denture fit as determined by self-report to nutrient and food intake among older Japanese.
The subjects were 353 Japanese aged 80 years in 2008 and were classified into four groups according to the number of POPs, defined as pairs of occluding natural, restored, or fixed prosthetic postcanine teeth (range: 0-8) and removable denture status. The groups were: (i) good dentition (n = 56; 8 POPs and no removable prosthesis), (ii) well-fitting dentures (n = 158; <8 POPs with self-reported good-fitting dentures), (iii) ill-fitting dentures (n = 70; <8 POPs with self-reported ill-fitting dentures), and (iv) compromised dentition (n = 69; <8 POPs and no removable prosthesis). Multivariable analysis of the differences in nutrient and food intake outcome variables which were collected via validated food frequency questionnaire among the four oral health status groups was conducted using general linear models. Results: Intake of multiple nutrients was significantly (P < 0.05) lower in the group with ill-fitting dentures or compromised dentition than in the good dentition group. Vegetable, fish, and shellfish consumption was significantly lower in the ill-fitting dentures or compromised dentition groups. No significant differences were seen in dietary intake between the well-fitting dentures and good dentition groups. Conclusions: Dietary intake was poorer in those with self-perceived ill-fitting dentures or fewer POPs than among those having all POPs. Regular dental care to maintain intact dentition, as well as dental treatment to replace missing teeth and ensure adequate denture fit and function, may be important to the diet intake and subsequent nutritional status of older Japanese.
本横断面研究旨在调查根据后牙咬合对（POPs）的存在情况定义的口腔健康状况以及通过自我报告确定的可摘义齿贴合度与日本老年人营养和食物摄入之间的关系。
研究对象为2008年353名80岁的日本人，根据POPs数量（定义为咬合的天然、修复或固定义齿后磨牙对的数量，范围：0 - 8）和可摘义齿状况分为四组。分组如下：（i）牙列良好（n = 56；8个POPs且无可摘义齿），（ii）义齿贴合良好（n = 158；POPs少于8个且自我报告义齿贴合良好），（iii）义齿贴合不良（n = 70；POPs少于8个且自我报告义齿贴合不良），（iv）牙列受损（n = 69；POPs少于8个且无可摘义齿）。使用一般线性模型对通过经验证的食物频率问卷收集的四个口腔健康状况组之间营养和食物摄入结果变量的差异进行多变量分析。结果：义齿贴合不良或牙列受损组的多种营养素摄入量显著低于（P < 0.05）牙列良好组。义齿贴合不良或牙列受损组的蔬菜、鱼类和贝类消费量显著较低。义齿贴合良好组和牙列良好组之间的饮食摄入量无显著差异。结论：自我感觉义齿贴合不良或POPs较少的人群的饮食摄入量比拥有所有POPs的人群差。定期进行牙齿护理以保持完整牙列，以及进行牙齿治疗以替换缺失牙齿并确保义齿贴合度和功能良好，可能对日本老年人的饮食摄入和随后的营养状况很重要。
