Abstract

Purpose: Depression is a leading cause of disability. Although tooth loss increases the risk of depressive symptoms, it is unclear whether dental prosthesis use moderates this risk. This study aimed to investigate whether dental prosthesis use moderates the association between tooth loss and new depressive symptoms in older adults.

Methods: This cohort study used data from the 2016 and 2019 Japan Gerontological Evaluation Study (JAGES). The participants were independent older adults aged ≥65 years without depressive symptoms in 2016. The onset of depressive symptoms in 2019 was the outcome variable. The exposure variables were dental status (≥20 teeth, 10-19 teeth with or without dental prostheses, and 0-9 teeth with or without dental prostheses) in 2016. Risk ratios (RRs) and 95% confidence intervals (CIs) were estimated using Poisson regression models with potential confounders as covariates.

Results: The analysis included 50,169 participants (mean age: 72.8 [standard deviation, 5.4] years). During follow-up, the incidence of depressive symptoms was 11.3%. Compared to those who had ≥20 teeth, the RR of depressive symptom onset was highest among those who had 0-9 teeth without dental prostheses (RR, 1.27; 95% CI, 1.04-1.56), after the adjustment for confounders. However, this risk was lower in those with 0-9 teeth and dental prostheses (RR, 1.08; 95% CI, 1.01-1.15).

Conclusions: These data highlight the potential of dental prostheses as an important factor in reducing the risk of depressive symptoms among individuals with severe tooth loss.

在牙齿严重缺失的老年人中,义齿的使用可缓和牙齿缺失与抑郁症状风险之间的关系:JAGES队列试验。
目的:抑郁症是导致残疾的一个主要原因。虽然牙齿缺失会增加出现抑郁症状的风险,但目前还不清楚义齿的使用是否会降低这种风险。本研究旨在探讨牙科修复体的使用是否会调节老年人牙齿缺失与新抑郁症状之间的关系:这项队列研究使用了 2016 年和 2019 年日本老年学评估研究(JAGES)的数据。参与者是2016年年龄≥65岁、无抑郁症状的独立老年人。2019年抑郁症状的出现是结果变量。解释变量为2016年的牙齿状况(≥20颗牙齿、10-19颗牙齿带或不带义齿、0-9颗牙齿带或不带义齿)。使用泊松回归模型估算了风险比(RRs)和95%置信区间(CIs),并将潜在的混杂因素作为协变量:分析包括 50,169 名参与者(平均年龄:72.8 [标准差,5.4] 岁)。在随访期间,抑郁症状的发生率为 11.3%。与拥有≥20颗牙齿的人相比,在调整了混杂因素后,拥有0-9颗牙齿且未安装假牙的人出现抑郁症状的RR最高(RR,1.27;95% CI,1.04-1.56)。然而,在拥有0-9颗牙齿并安装了义齿的人群中,这一风险较低(RR,1.08;95% CI,1.01-1.15):这些数据凸显了义齿作为降低严重缺牙患者抑郁症状风险的一个重要因素的潜力。
