Abstract

Objectives: This study aims to examine vulnerable ADL-based subgroups of Chinese older adults, their links to depressive symptoms, and life satisfaction as a mediating factor.

Methods: We screened 8,211 participants aged 60 years and above who met the inclusion criteria from 2018 CHARLS. The different subgroups of ADL were identified by latent profile analysis. Life satisfaction and depressive symptoms were compared among the various ADL subgroups. Mediation analysis helped investigate the mediating role of life satisfaction between the various subgroups of ADL and depressive symptoms.

Results: Two vulnerable subgroups of ADL were identified (Low Damaged class and High Damaged class), along with another subgroup of ADL (Not Damaged class), comprising the majority of Chinese older adults. The vulnerable subgroups of ADL had significantly lower life satisfaction and higher levels of depressive symptoms. The relationship between depressive symptoms and the vulnerable subgroups of ADL was partially mediated by life satisfaction.

Conclusion: The results emphasize the role of life satisfaction in linking ADL with depressive symptoms, indicating potential areas for interventions to reduce depressive symptoms among older adults. This study is limited by its cross-sectional design precluding causal inference, reliance on self-reported data and unexplored moderating factors.

中国老年人日常生活活动与抑郁症状：潜在特征和中介分析

目的：本研究旨在探讨中国老年人的弱势adl亚群，他们与抑郁症状的联系，以及生活满意度作为中介因素。方法：从2018年CHARLS中筛选符合纳入标准的60岁及以上的8211名参与者。通过潜在剖面分析对ADL的不同亚组进行鉴定。比较不同ADL亚组患者的生活满意度和抑郁症状。中介分析有助于探讨生活满意度在ADL各亚组与抑郁症状之间的中介作用。结果：确定了ADL的两个易感亚组（低损伤级和高损伤级），以及ADL的另一个亚组（未损伤级），包括大多数中国老年人。ADL易感亚组的生活满意度较低，抑郁症状水平较高。生活满意度在抑郁症状与ADL易感亚群的关系中起部分中介作用。结论：研究结果强调了生活满意度在ADL与抑郁症状之间的联系中的作用，指出了干预减少老年人抑郁症状的潜在领域。本研究的局限性在于其横断面设计排除了因果推理，依赖于自我报告的数据和未探索的调节因素。
