Abstract

Background: The association between oral health and general health is not yet fully understood. This study examines the association between missing teeth, mortality, and hospitalization outcomes.

Data and methods: This cohort study utilized time-to-event data from the Canadian Health Measures Survey Cycle 1 (2007 to 2009) linked to death and hospital discharge records. Participants with clinically assessed tooth counts were followed up to 2019. Cox proportional hazards models were used, treating missing teeth as either categorical or continuous exposures, adjusting for socioeconomic and health-related factors.

Results: In participants aged 20 to 79 years, 3,450 records were linked to mortality data (n=300 deaths) and 2,250 to hospitalization data (n=650 with at least one hospital stay). Missing teeth were associated with elevated all-cause and cancer mortality in unadjusted models, but not after covariate adjustment. After adjusting for key risk factors, including age and sex, participants with five or more missing teeth had a 76% higher risk of all-cause hospitalization (hazard ratio [HR] 1.76, 95% confidence interval [CI]: 1.41 to 2.20) and a 120% higher risk of circulatory-related hospitalization (HR 2.20, 95% CI: 1.09 to 4.45). Respiratory hospitalizations were also linked to missing teeth. No significant links were found with hospitalizations for digestive diseases or cancer.

Interpretation: Missing teeth is associated with hospitalization in Canadian adults. These findings highlight that oral health may play a role or serve as an indicator of overall health and health service use among Canadian adults.

缺牙、死亡率和住院：来自加拿大健康措施调查和相关数据库的基于人群的队列分析

背景：口腔健康与一般健康之间的关系尚未完全了解。本研究探讨了缺牙、死亡率和住院治疗结果之间的关系。数据和方法：本队列研究利用了加拿大健康措施调查周期1（2007年至2009年）与死亡和出院记录相关的事件发生时间数据。临床评估牙齿计数的参与者随访至2019年。使用Cox比例风险模型，将缺失牙齿视为分类或连续暴露，调整社会经济和健康相关因素。结果：在20至79岁的参与者中，3450条记录与死亡数据相关（n=300例死亡），2250条记录与住院数据相关（n=650例至少住院一次）。在未调整的模型中，缺牙与全因死亡率和癌症死亡率升高有关，但在协变量调整后则无关。在调整了包括年龄和性别在内的关键危险因素后，缺失五颗或更多牙齿的参与者的全因住院风险高出76%（危险比[HR] 1.76, 95%可信区间[CI]: 1.41至2.20），循环相关住院风险高出120%（危险比[HR] 2.20, 95%可信区间[CI]: 1.09至4.45）。因呼吸道疾病住院治疗也与缺牙有关。没有发现因消化系统疾病或癌症住院的显著联系。解释：在加拿大成年人中，缺牙与住院有关。这些发现强调，口腔健康可能在加拿大成年人的整体健康和卫生服务使用中发挥作用或作为一个指标。
