This study investigated the effects of falls on self-rated health and anxiety symptoms and the moderating role of psychological resilience in Chinese older persons with chronic multimorbidity.
Data were taken from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS). We used a linear regression model to evaluate the associations among falls and self-rated health and anxiety symptoms, the moderating role of psychological resilience was verified by moderation analysis, and we also used a replacement model to test robustness. Finally, the results of the study were further verified via heterogeneity analysis through subgroup regression.
A total of 2933 people aged 60 years or older with chronic multimorbidity were included in our study. The linear regression results revealed that falls were significantly negatively correlated with the self-rated health symptoms of older Chinese people with chronic multimorbidity (β = -0.1703, p < 0.01) and significantly positively correlated with anxiety symptoms (β = 0.5590, p < 0.01). Among the moderating effects, we found that psychological resilience played a moderating role between falls and anxiety symptoms (β = - 0.151 [-0.217, -0.084], p < 0.01). Finally, we found heterogeneity in the study results by sex, residence and number of chronic diseases.
Falls are associated with poorer self-rated health and higher anxiety levels among older persons with chronic multimorbidity in China. High levels of psychological resilience have a moderating effect on the development of anxiety symptoms.
本研究旨在探讨中国患有慢性多种疾病的老年人中，跌倒对自我健康评估和焦虑症状的影响，以及心理弹性的调节作用。
数据来自 2018 年中国长寿纵向研究（CLHLS）。我们采用线性回归模型评估跌倒与自我健康评估和焦虑症状之间的关联，通过调节分析验证心理弹性的调节作用，并采用替代模型进行稳健性检验。最后，通过亚组回归的异质性分析进一步验证研究结果。
共纳入 2933 名患有慢性多种疾病且年龄在 60 岁及以上的老年人。线性回归结果表明，跌倒与中国患有慢性多种疾病的老年人的自我健康评估症状显著负相关（β = -0.1703，p < 0.01），与焦虑症状显著正相关（β = 0.5590，p < 0.01）。在调节作用方面，我们发现心理弹性在跌倒和焦虑症状之间起到调节作用（β = -0.151 [-0.217，-0.084]，p < 0.01）。最后，我们发现研究结果存在性别、居住地点和慢性疾病数量的异质性。
在中国患有慢性多种疾病的老年人中，跌倒与自我健康评估较差和焦虑水平升高有关。高水平的心理弹性对焦虑症状的发展具有调节作用。
