Because there are more elderly people than ever before and because they are living for longer periods of time, it is essential to understand the determinants of healthy ageing. This study examined changes in oral health-related quality of life (OHRQoL) among Japanese elderly over a 7-year period. A sample of independently living individuals (aged 60+ years) underwent a questionnaire and dental examination at baseline and 7 years afterwards. The Geriatric Oral Health Assessment Index (GOHAI) was used to assess the impact of oral conditions. Occlusal force and salivary flow were also assessed. Of the 411 participants assessed at baseline, 130 (31·6%) accepted to participate after 7 years. There were no significant differences between those lost to follow-up and those assessed at 7 years, except that a higher proportion of the latter rated their baseline general health as good. Among the latter, the overall mean GOHAI score did not change significantly (11·8 at baseline and 11·1 at follow-up; P = 0·16). However, after controlling for age, gender and baseline GOHAI score, participants who had lost teeth or experienced a decline in occlusal force after 7 years had higher follow-up GOHAI scores (indicating poorer OHRQoL). Unfavourable changes in clinical oral status over time are reflected in poorer self-rated oral health.
由于现在老年人比以往任何时候都多，而且他们的寿命也越来越长，因此了解健康老龄化的决定因素至关重要。本研究调查了日本老年人在 7 年内口腔健康相关生活质量（OHRQoL）的变化。一项针对独立生活的个体（年龄在 60 岁以上）的样本在基线和 7 年后进行了问卷调查和口腔检查。使用老年口腔健康评估指数（GOHAI）评估口腔状况的影响。还评估了咬合力量和唾液流量。在基线评估的 411 名参与者中，有 130 名（31.6%）在 7 年后同意参与。失访者和 7 年后评估者之间没有显著差异，除了后者中更多的人将他们的基线一般健康状况评为良好。在后者中，总体平均 GOHAI 评分没有显著变化（基线时为 11.8，随访时为 11.1；P = 0.16）。然而，在控制年龄、性别和基线 GOHAI 评分后，7 年后失去牙齿或咬合力量下降的参与者的随访 GOHAI 评分更高（表明 OHRQoL 更差）。随着时间的推移，临床口腔状况的不利变化反映在自我报告的口腔健康状况较差上。
