To study the associations of instrumental activities of daily living (IADL) and the handgrip strength with oral self-care among dentate home-dwelling elderly people in Finland.
The study analysed data for 168 dentate participants (mean age 80.6 years) in the population-based Geriatric Multidisciplinary Strategy for Good Care of the Elderly (GeMS) study. Each participant received a clinical oral examination and structured interview in 2004-2005. Functional status was assessed using the IADL scale and handgrip strength was measured using handheld dynamometry.
Study participants with high IADL (scores 7-8) had odds ratios (ORs) for brushing their teeth at least twice a day of 2.7 [95% confidence intervals (CI) 1.1-6.8], for using toothpaste at least twice a day of 2.0 (CI 0.8-5.2) and for having good oral hygiene of 2.8 (CI 1.0-8.3) when compared with participants with low IADL (scores ≤6). Participants in the upper tertiles of the handgrip strength had ORs for brushing the teeth at least twice a day of 0.9 (CI 0.4-1.9), for using the toothpaste at least twice a day of 0.9 (CI 0.4-1.8) and for good oral hygiene of 1.1 (CI 0.5-2.4) in comparison with the study subjects in the lowest tertile of handgrip strength.
The results of this study suggest that the functional status, measured by means of the IADL scale, but not handgrip strength, is an important determinant of oral self-care among the home-dwelling elderly.
研究日常生活活动能力（IADL）和握力与芬兰 dentate 居家老年人口腔自我护理的关系。
本研究分析了基于人群的老年综合多维策略良好老年护理（GeMS）研究中 168 名 dentate 参与者（平均年龄 80.6 岁）的数据。每位参与者在 2004-2005 年接受了临床口腔检查和结构化访谈。使用 IADL 量表评估功能状态，使用手持测力计测量握力。
具有高 IADL（得分 7-8）的研究参与者每天至少刷牙两次的优势比（OR）为 2.7（95%置信区间（CI）1.1-6.8），每天至少使用牙膏两次的 OR 为 2.0（CI 0.8-5.2），口腔卫生良好的 OR 为 2.8（CI 1.0-8.3），与 IADL 较低（得分≤6）的参与者相比。握力处于上三分位的参与者每天至少刷牙两次的 OR 为 0.9（CI 0.4-1.9），每天至少使用牙膏两次的 OR 为 0.9（CI 0.4-1.8），口腔卫生良好的 OR 为 1.1（CI 0.5-2.4），与握力最低三分位的研究对象相比。
本研究结果表明，通过 IADL 量表测量的功能状态，而不是握力，是居家老年人口腔自我护理的重要决定因素。
