背景：尚无研究探讨牙齿数量与睡眠障碍之间的关联。因此，我们研究了老年人的牙齿数量和睡眠持续时间之间的关联，考虑到牙齿数量减少与下颌位置变化导致睡眠呼吸暂停之间存在联系的证据。方法：在这项研究中，我们使用了 23,444 名队列参与者样本的信息，这些参与者是从 2010 年日本老年学评估研究中随机抽取的 (N = 169,215)。结果变量是自我报告的睡眠持续时间（小时/天），解释变量是自我报告的牙齿数量（0、1 -9、10-19、> = 20）。我们将年龄、性别、体重指数、教育程度、平均家庭年收入、抑郁症状、体力活动、日常生活活动、是否患有糖尿病和吸烟状况作为协变量。在 20,548 名符合条件的参与者中使用了多项 Logistic 回归，并提供了所有必要的信息。结果：平均年龄为 73.7（标准差 = 6.13）岁。大多数参与者（28.1%）报告睡眠时间为 7 小时，而一小部分参与者报告睡眠时间较短（= 10 小时，4.7%）。无牙颌参与者的比例为 14.7%。以 7 小时睡眠时间作为参考类别，无牙颌参与者（相对风险比 (RRR) = 1.43，95% 置信区间 (CI) = 1.07-1.90）或一到九颗牙齿（RRR = 1.29，95% CI = 1.02-1.63）的睡眠时间短的相对风险比显着较高，与协变量无关。此外，他们的睡眠时间较长的相对风险比较高（分别为RRR = 1.75，95% CI = 1.40-2.19；RRR = 1.48，95% CI = 1.21-1.81）。结论：与拥有20颗或更多牙齿的人相比，牙齿少于10颗的老年人睡眠时间短和长的风险更高。 (c) 2018 Elsevier B.V. 保留所有权利。
Background: No studies have examined the associations between the numbers of teeth and sleep disturbance. Therefore, we examined the associations between the number of teeth and sleep duration in older people, considering the evidence linking fewer teeth and sleep apnoea through changes in jaw position.Methods: For this study we used information from a sample of 23,444 cohort participants, randomly selected from the Japan Gerontological Evaluation Study 2010 (N = 169,215). The outcome variable was self-reported sleep duration (h/day), and the explanatory variable was self-reported number of teeth (0, 1 -9, 10-19, >= 20). We treated age, sex, body mass index, educational attainment, annual equalized household income, depressive symptoms, physical activity, activities of daily living, presence of diabetes, and smoking status as covariates. Multinomial logistic regression was used among the 20,548 eligible participants with all necessary information.Results: The mean age was 73.7 (standard deviation = 6.13) years. Most participants (28.1%) reported sleep duration of 7 h, while a small proportion of the participants reported short (= 10 h, 4.7%) sleep duration. The proportion of edentulous participants was 14.7%. Taking the 7-h sleep duration as the reference category, edentulous participants (relative risk ratio (RRR) = 1.43, 95% confidence interval (CI) = 1.07-1.90) or one to nine teeth (RRR = 1.29, 95% CI = 1.02-1.63) had a significantly higher relative risk ratio for short sleep, independent of covariates. Furthermore, they had a higher relative risk ratio for long sleep duration (RRR = 1.75, 95% CI = 1.40-2.19; RRR = 1.48, 95% CI = 1.21-1.81, respectively).Conclusions: Compared to people with 20 or more teeth, older adults with fewer than 10 teeth have higher risks for short and long sleep durations.
