Objective. The aim of this study was to assess the relationship between subjective oral health status and lifestyle in elderly people living in Japan. Methods. Subjects were 5383 inhabitants of the Kagawa Prefecture, Japan, at the age of 75-100. Records of the number of remaining teeth and the data from self-reported questionnaire were analyzed statistically. Results. Remaining teeth were significantly correlated to "no current smoking," while not related to other lifestyle. On the other hand, "subjective masticatory ability" defined as a condition allowing chewing all foods well was related to favorable lifestyles. "Subjective masticatory ability" was also related to "not feeling stress," "no deviated food habit" as well as to other good oral health conditions. A logistic regression analysis for "remaining teeth more than 20" revealed a significant relationship between "no current smoking" (OR = 1.582) and "no alcohol drinking" (OR = 0.851). Regarding "subjective masticatory ability," all favorable lifestyles analyzed in this study were found to be significant positive factors. Conclusions. "Subjective masticatory ability" seems to be strongly associated with favorable lifestyles. Therefore, it can be suggested that "subjective masticatory ability" might be a good landmark for quality of life of elderly people in addition to the number of remaining teeth.
目的。本研究旨在评估日本老年人主观口腔健康状况与生活方式之间的关系。方法。研究对象为日本香川县5383名年龄在75至100岁之间的居民。对剩余牙齿数量记录和自我报告问卷数据进行统计学分析。结果。剩余牙齿数量与“目前不吸烟”显著相关，而与其他生活方式无关。另一方面，被定义为能够良好咀嚼所有食物的“主观咀嚼能力”与健康的生活方式相关。“主观咀嚼能力”还与“无压力感”“无偏食习惯”以及其他良好的口腔健康状况相关。对“剩余牙齿超过20颗”进行的逻辑回归分析显示，“目前不吸烟”（OR = 1.582）和“不饮酒”（OR = 0.851）之间存在显著关系。关于“主观咀嚼能力”，本研究分析的所有健康生活方式均为显著的积极因素。结论。“主观咀嚼能力”似乎与健康的生活方式密切相关。因此，可以认为“主观咀嚼能力”除了剩余牙齿数量外，可能是老年人生活质量的一个良好指标。
