We examined the associations of activities of daily living (ADL) and instrumental activities of daily living (IADL) with changes in sleep-related measurements among Chinese older adults from 2005 to 2014.
Four waves of longitudinal data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS; 2005-2014; n = 42,417) were used. Two sleep-related measurements were included: sleep quality and meeting the recommended daily sleep duration (7-8 h). We used Cox two-state regression models to examine the different states of sleep quality and duration.
Approximately 43.6% of observations were between 81 and 95 years old, and 35.9% were between 65 and 80 years old. Around 54.8% of observations were female. Older adults with more ADL and IADL limitations had a higher risk of experiencing declines in sleep quality and the transition from meeting to not meeting the recommended sleep duration over time (all p < 0.01).
ADL and IADL limitations are significant risk factors for the development of sleep-related issues over time among Chinese older adults. Functional limitations need to be included in intervention strategies focused on sleep hygiene and studies examining changes in sleep patterns over time.
我们考察了中国老年人日常生活活动（ADL）和工具性日常生活活动（IADL）与 2005 年至 2014 年期间睡眠相关测量变化的关联。
使用中国健康长寿纵向研究（CLHLS）的 4 个纵向数据波次（2005-2014 年；n=42417）。纳入了两项睡眠相关测量指标：睡眠质量和是否符合推荐的每日睡眠时间（7-8 小时）。我们使用 Cox 双状态回归模型来检查睡眠质量和持续时间的不同状态。
大约 43.6%的观察结果年龄在 81 至 95 岁之间，35.9%的观察结果年龄在 65 至 80 岁之间。大约 54.8%的观察结果为女性。ADL 和 IADL 限制较多的老年人随着时间的推移，出现睡眠质量下降和从不满足推荐睡眠时间转变为满足睡眠时间的风险更高（均 p<0.01）。
ADL 和 IADL 限制是中国老年人随着时间推移出现睡眠相关问题的重要危险因素。在关注睡眠卫生的干预策略中需要纳入功能限制因素，并研究随时间推移睡眠模式的变化。
