家庭养老面临着抚养比的增加，子女与老人的同住比下降等问题，一定程度的影响了家庭代际支持的发生。但中国慢性病老年人的基数仍在不断增大，家庭养老仍作为主要的养老方式。在这种背景下，研究家庭代际支持中经济支持、照料支持、情感支持发生的情况，发生这些支持对慢性病老年人的生活满意度产生的影响，可以更好的促进慢性病老年人保持健康的生理、心理，为慢性病老年人提供良好的家庭支持环境，促进健康中国、健康老龄化的建设。本研究使用《中国健康与养老追踪调查(简称CHARLS)》数据库中的Harmonized CHARLS数据，筛选出2018年8268个观测样本，分析样本比例特征，选择合适的logistic回归模型进行数据处理，通过估计模型的拟合优度、回归后的分类统计量、AUC值来评估模型的拟合度和准确率。结果显示，（1）在2018年，慢性病老年人对生活呈现出满意的状态有88.36%，提供经济支持有39.83%，收到经济支持的有85.18%，有孙子女且帮助子女照料的有40.20%，无孙子女不需要提供照料的有3%，有日常生活困难接受子女照料的有14.03%，无日常生活困难接受照料的有57.37%，发生情感支持的有88.44%。（2）在不同模型中，相比于不提供经济、照料支持、不发生情感支持的慢性病老年人，提供经济支持（OR=1.11、1.07）、收到经济支持（OR=1.27、1.23）、有日常生活困难收到照料支持（OR=1.07、1.04）、无日常生活困难收到照料支持（OR=1.97、1.96）、发生情感支持（OR=1.38、1.38）的生活满意度要高，而有孙子女提供照料支持（OR=0.93、0.91）、无孙子女不需要提供照料支持（OR=0.63、0.63）的生活满意度低。因此建议，在家庭层面：（1）培养慢性病老年人就医意识，提高慢性病老年人健康水平；（2）提供适当的照料和关心，营造舒适居家养老环境。在社会层面：（1）完善激励保障性政策，保障代际支持作用发挥；（2）多主体参与健康养老，配合家庭代际支持。

Family old-age care is facing problems such as an increase in the dependency ratio and a decrease in the ratio of children living with the elderly, which to some extent affects the occurrence of intergenerational family support. However, the base of chronically ill elderly people in China is still increasing, and family old-age care still serves as the main mode of old-age care. In this context, studying the occurrence of economic support, care support, and emotional support in intergenerational family support, and the impact of the occurrence of these supports on the life satisfaction of chronically ill older adults can better promote the maintenance of healthy physiology and psychology of chronically ill older adults, provide a good family support environment for chronically ill older adults, and contribute to the construction of a healthy China and healthy aging. In this study, we used the Harmonized CHARLS data from the China Health and Aged Care Tracking Survey (CHARLS) database to screen a sample of 8,268 observations in 2018, analyse the characteristics of the sample proportions, select an appropriate logistic regression model for data processing, and by estimating the model's goodness-of-fit, post-regression categorical statistics, and AUC values to assessing the fit and accuracy of the model. The results showed that, (1) in 2018, 88.36% of chronically ill older adults showed satisfaction with life, 39.83% provided financial support, 85.18% received financial support, 40.20% had grandchildren and helped their children to care for them, 3% had no grandchildren who did not need to be provided with care, 14.03% received care from their children for daily living difficulties, no daily life difficulties receiving care was 57.37%, and emotional support occurred in 88.44%. (2) In the different models, compared to the chronically ill older adults who did not provide financial and care support and did not experience emotional support, those who provided financial support (OR=1.11, 1.07), received financial support (OR=1.27, 1.23), received care support with daily living difficulties (OR=1.07, 1.04), received care support without daily living difficulties (OR=1.97 , 1.96), and emotional support occurring (OR=1.38, 1.38) were higher, while those with grandchildren providing care support (OR=0.93, 0.91), and those with no grandchildren not needing to provide care support (OR=0.63, 0.63) had low life satisfaction. Based on these findings, the following recommendations are made: At the family level: (1) cultivate awareness of the need for medical care for the chronically ill elderly and improve the health of the chronically ill elderly; (2) provide appropriate care and attention and create a comfortable environment for ageing at home. At the social level: (1) improve incentive and guarantee policies to ensure intergenerational support; (2) involve multiple actors in healthy ageing to complement intergenerational family support.
