目的：口腔健康不良已被报道为死亡率的危险指标，然而，关于咀嚼能力和死亡率之间的关系的数据很少。我们研究了老年人自评咀嚼能力与死亡率的关系。设计：前瞻性研究。对象和方法：日本福冈县1282人(80岁)中的697人(男性277人，女性420人)参与研究。通过问卷调查获得口腔和全身健康状况数据，并进行体格和实验室血液检查。咀嚼能力是根据问卷调查报告的每个受试者能够咀嚼的食物类型的数量来评估的。结果：在1998-2002年间，共有108名受试者死亡。那些咀嚼次数最少的人比那些能够咀嚼所有15种调查食物的人死亡风险更高[危险比(HR)=2.38，95%可信区间(95%CI)=1.07-5.29]，尽管其他参数包括当前吸烟、低血清白蛋白和身体健康状况较差更显著。此外，软性食物的咀嚼能力降低增加了风险(HR=2.65，95%CI=1.20-5.87)。结论：在80岁的社区居民中，咀嚼能力与死亡率有关，并可能是生存率的预测因素。
OBJECTIVE: Poor oral health has been reported to be a risk indicator of mortality, however, few data are available regarding the relationship between chewing ability and mortality. We examined the relationship between self-assessed chewing ability and mortality in elderly subjects.DESIGN: Prospective study.SUBJECTS AND METHODS: Participating in the study were 697 people (277 males, 420 females) from 1282 individuals (80 years old) residing in Fukuoka Prefecture, Japan. Data on oral and systemic health status through questionnaires, accompanied by physical and laboratory blood examinations were obtained. Chewing ability was assessed based on the number of types of food each subject reported as able to chew by questionnaire.RESULTS: A total of 108 subjects died between 1998 and 2002. Those with the lowest number of chewable foods were associated with higher risk of mortality than those with the ability to chew all of the 15 types of food surveyed [hazard ratio (HR) = 2.38, 95% confidence interval (95% CI) = 1.07-5.29], though other parameters including current smoking, low serum albumin, and poor physical health status were more significant. Further, reduced chewing ability of soft foods increased the risk (HR = 2.65, 95% CI = 1.20-5.87).CONCLUSION: Chewing ability was associated with mortality in a population of 80-year-old community residents, and may be a predictor for survival rate.
