癌症、健康状况与中老年群体主观预期寿命研究

Research of Cancer,Health Status and Subjective Life Expectancy of The Middle-aged and Elderly Groups

将健康状况作为中介解释机制通过CHARLS数据,建立多元逐步回归模型,检验健康状况的多重中介效应,从理论与实证上考察癌症对主观预期寿命的影响与路径。结果显示,中老年癌症群体对生命剩余时间具有悲观的预期,拥有较低水平的主观预期寿命。健康状况在癌症与中老年群体主观预期寿命之间起到部分中介作用。癌症对主观预期寿命的间接影响主要通过主观健康层次的自评健康效应进行,通过客观健康层次的ADL受损指数效应以及IADL受损指数效应对主观预期寿命产生的影响非常有限。因此,探讨癌症、健康状况与主观预期寿命的多重关系,有助于积极应对人口老龄化挑战和全面推进健康中国建设进程,进而提升人民生命的质量。

This paper uses health status as an intermediary mechanism,and establishes a multiple stepwise regression model to test the multiple intermediary effects of health status,and investigates the impact and its path of cancer on subjective life expectancy from theoretical and methodological aspects based on the CHARLS data.The result shows that the middle-aged and elderly groups with cancer survivors have a pessimistic expectation with their remaining life time,and have a low level of subjective life expectancy.Health status plays a mediating role between cancer and subjective life expectancy of the middle-aged and elderly groups.The indirect impact of cancer on subjective life expectancy is mainly through the self-rated health effect of the subjective health level,at the same time is very limited through the ADL damage index effect and IADL damage index effect of the objective health level.Therefore,it is very important to explore the multiple relationships between cancer,health status and subjective life expectancy.This study can help the relevant department to deal with the challenge of population aging,and promote the construction of the healthy China,and then to improve the quality of people's life.
