目的：本研究旨在调查日本社区老年男性和女性的全牙弓双侧最大咬合力（MOF）与全因死亡率之间的关系。方法：这项为期13年的前瞻性队列研究在815名老年人中进行（395名男性和420名女性）年龄70岁或以上（平均年龄+/-标准差：75.1 +/- 4.5岁）。用马蹄形压敏片记录牙尖交错位的双侧MOF。根据MOF将参与者按性别分组为三分位数。还评估了人口统计学变量、慢性病、合并症、身体状况、认知和心理状况、社会功能和血液化学数据。有关全因死亡和迁移的信息来自仙台市政府。考克斯比例风险模型进行评估全因死亡率在随访period.Results：在总共，159名男性和109名女性参与者死亡超过中位数12.9年的随访期，和累积死亡率显着增加，在男性和女性的MOF较低。多变量考克斯比例风险模型显示，与男性中的上三分位数相比，与MOF的下三分位数相关的全因死亡风险显著增加（风险比：1.62; 95%置信区间：1.05-2.51）和女性（危险比：1.94; 95%可信区间：1.10-3.56）.结论：在日本社区居住的老年男性和女性中，双侧MOF与全因死亡率有显著的独立相关性。这些研究结果表明，维持口腔功能有助于整体健康。(C)2019日本口腔修复学会。由爱思唯尔有限公司出版。保留所有权利。
Purpose: This study aimed to investigate the relationship between the bilateral maximum occlusal force (MOF) of full dental arches and all-cause mortality in a group of community-dwelling older males and females in Japan.Methods: This 13-year prospective cohort study was conducted among 815 older adults (395 male and 420 female) aged 70 years or over (mean age +/- standard deviation: 75.1 +/- 4.5 years). Bilateral MOF in the intercuspal position was recorded with horseshoe-shaped pressure-sensitive film. Participants were grouped by gender into tertiles according to MOF. Demographic variables, chronicity, comorbidity, physical status, cognitive and psychological status, social functioning, and blood chemistry data were also assessed. Information regarding all-cause mortality and migration was obtained from the Sendai Municipal Authority. Cox proportional hazard modeling was performed to assess all-cause mortality during the follow-up period.Results: In total, 159 male and 109 female participants died over a median 12.9-year follow-up period, and the cumulative mortality significantly increased with lower MOF in both males and females. The multivariate Cox proportional hazard model demonstrated a significant increase in the risk of all-cause mortality associated with lower tertiles of MOF, relative to the upper tertile in males (hazard ratio: 1.62; 95% confidence interval: 1.05-2.51) and females (hazard ratio: 1.94; 95% confidence interval: 1.10-3.56).Conclusions: There was a significant and independent association of bilateral MOF with all-cause mortality in community-dwelling elderly males and females in Japan. These findings suggested that maintenance of oral functioning contributes to general health. (C) 2019 Japan Prosthodontic Society. Published by Elsevier Ltd. All rights reserved.
