With the rapidly aging world population, Japan has many older people with difficulties in maintaining oral health. This study aimed to investigate the relationship between dietary hardness score and performance of activities of daily living (ADL) of 90-year-old individuals in rural areas of Japan.
A total of 236 individuals (64 men and 172 women) aged 90 years in Mitsugi town, Hiroshima, Japan, were included. Assessment of oral status and survey of ADL were performed. The association of ADL with dietary hardness score and the number of remaining teeth was determined.
The mean dietary hardness score was 8.3 ± 2.6. Eighty individuals showed independence in ADL, whereas 156 individuals showed dependence. Logistic regression analysis, adjusted for potential confounding factors, showed that dietary hardness score was associated with ADL status but not the number of remaining teeth.
Our findings suggest that a low dietary hardness score is associated with dependence on ADL in 90-year-old individuals.
随着世界人口的快速老龄化,日本有许多老年人在维持口腔健康方面存在困难。本研究旨在调查日本农村地区 90 岁人群的饮食硬度评分与日常生活活动(ADL)表现之间的关系。
共纳入日本广岛县三津町 236 名 90 岁的个体(64 名男性和 172 名女性)。进行口腔状况评估和 ADL 调查。确定 ADL 与饮食硬度评分和剩余牙齿数量之间的关联。
平均饮食硬度评分为 8.3±2.6。80 名个体表现出 ADL 独立性,而 156 名个体表现出 ADL 依赖性。调整潜在混杂因素的 logistic 回归分析显示,饮食硬度评分与 ADL 状态相关,但与剩余牙齿数量无关。
我们的研究结果表明,饮食硬度评分较低与 90 岁个体对 ADL 的依赖有关。
