关于牙列状态和饮食摄入之间的时间关联的信息有限。这项为期5年的前瞻性队列研究的目的是调查日本老年人牙齿受损是否与随后饮食摄入量下降有关。286名日本社区居民参与了这项研究，他们的基线年龄均为75岁。功能牙单位（FTUs），定义为一对相对的天然或假牙，不包括第三磨牙（范围：0-14），在基线牙科检查的基础上进行计数。有5个ftu的个体被定义为牙齿受损。在基线和5年后，使用有效的饮食问卷评估饮食摄入量。在对潜在混杂因素进行调整后，采用稳健回归分析来评估有和没有功能牙列受损的参与者之间饮食摄入量变化的差异。61名研究参与者（213%）被定义为牙列受损。总的来说，所有估计的饮食变量（能量、营养素和食物组）的平均值随着时间的推移而下降。值得注意的是，在调整了潜在的混杂因素后，牙列受损的个体在多种营养素（蛋白质、钠、钾、钙、维生素a、维生素E和膳食纤维）和食物组（蔬菜和肉类）的摄入量上的下降程度显著（P < 0.05）大于牙列未受损的个体。本研究的结果描述了在日本老年人中，牙列受损与选定营养和食物组摄入量下降的时间关联。
Limited information is available on the temporal association between dentition status and dietary intake. The aim of this 5-year prospective cohort study was to investigate whether impaired dentition was associated with subsequent decline in dietary intake in older Japanese adults. Two hundred and eighty-six community-dwelling Japanese individuals, all aged 75 years at baseline, were included in the study. Functional tooth units (FTUs), defined as a pair of opposing natural or prosthetic teeth excluding third molars (range: 0-14), were counted on the basis of baseline dental examinations. Individuals with 5 FTUs were defined as having impaired dentition. Dietary intake was assessed at baseline and 5 years later, using a validated dietary questionnaire. Robust regression analyses were used to evaluate the differences in change in dietary intake between participants with and without impaired functional dentition, after adjustment for potential confounders. Sixty-one study participants (213 %) were defined as having impaired dentition. Overall, mean values for all estimated dietary variables (energy, nutrients and food groups) declined over time. Notably, individuals with impaired dentition demonstrated a significantly (P < 005) greater degree of decline in the intake of multiple nutrients (protein, sodium, potassium, calcium, vitamin A, vitamin E and dietary fibre) and food groups (vegetable and meat) than those without impaired dentition, after adjusting for potential confounders. The results of this study describe the temporal association of impaired dentition with the decline in selected nutrient and food group intake among older Japanese adults.
