This study aimed to explore the relationship between adverse childhood experiences (ACEs), sleep, and lower extremity function in older adults using a nationally representative cohort.
This study included 4,439 participants aged 60 years or older (mean age: 67.2 ± 5.7 years) from the China Health and Retirement Longitudinal Study (CHARLS) 2015 national survey and the 2014 Life History Survey. ACEs, sleep duration, and sleep quality were assessed through self-report, and lower extremity function was measured using the Short physical performance battery (SPPB). The relationships between ACEs, sleep, and lower extremity function were analyzed using multivariate linear regression model and restricted cubic splines.
After adjusting for covariates, older adults with four or more ACEs exhibited worse lower extremity function compared to those with no ACEs (β: -0.175). 6-8 h of sleep was associated with improved lower extremity function (β: 0.119), while good sleep quality was also associated with higher lower extremity function scores (β: 0.177). Age-related differences revealed that the association between four or more ACEs and reduced lower extremity function (β: -0.431) was significant only in individuals aged 70 years and older. In the 60-69 years age group, the sleep duration of 6-8 h was significantly related to better lower extremity function (β: 0.150), however, in those aged 70 years and older, more than 8 h of sleep was associated with poorer function (β: -0.378). Furthermore, good sleep quality was associated with better lower extremity function in individuals aged 70 years and older (β: 0.246).
ACEs, particularly household mental illness and parental disability, are associated with poorer lower extremity function in older adults. Normal sleep duration and good sleep quality are linked to better lower extremity function and may mitigate the negative effects of ACEs. However, these associations vary by age.
本研究旨在利用具有全国代表性的队列，探讨老年人童年不良经历（ACEs）、睡眠与下肢功能之间的关系。
本研究纳入了来自中国健康与养老追踪调查（CHARLS）2015年全国调查和2014年生活史调查的4439名60岁及以上的参与者（平均年龄：67.2±5.7岁）。通过自我报告评估ACEs、睡眠时间和睡眠质量，并使用简短体能状况量表（SPPB）测量下肢功能。使用多元线性回归模型和受限立方样条分析ACEs、睡眠与下肢功能之间的关系。
在调整协变量后，与没有ACEs的老年人相比，有四个或更多ACEs的老年人下肢功能更差（β：-0.175）。6-8小时的睡眠与改善的下肢功能相关（β：0.119），而良好的睡眠质量也与更高的下肢功能评分相关（β：0.177）。年龄差异显示，四个或更多ACEs与下肢功能降低之间的关联（β：-0.431）仅在70岁及以上的个体中显著。在60-69岁年龄组中，6-8小时的睡眠时间与更好的下肢功能显著相关（β：0.150），然而，在70岁及以上的人群中，超过8小时的睡眠与较差的功能相关（β：-0.378）。此外，良好的睡眠质量与70岁及以上个体更好的下肢功能相关（β：0.246）。
ACEs，尤其是家庭精神疾病和父母残疾，与老年人较差的下肢功能有关。正常的睡眠时间和良好的睡眠质量与更好的下肢功能相关，可能减轻ACEs的负面影响。然而，这些关联因年龄而异。
