数字融入和健康生活方式对社会经济状况与老年入抑郁关系的序列中介作用
Sequential mediating role of digital participation and health lifestyle in the relation-ship between socioeconomic status and depression of older adults
摘要
Abstract
Objective:To explore the potential mechanisms of the relationship between socioeconomic status(SES)and depression of Chinese older adults through the mediating role of digital participation and health lifestyle.Methods:Using the nationally representative data from the China Family Panel Studies in 2020,4 846 participants aged 60 years and older were analyzed in our study.We explored the potential mechanisms of the relationship between SES and depression of Chinese older adults in the digital era through a chain multiple mediating effects model.The KHB(The Karlson,Holm,and Breen)method was used to analyze the mediating role of digital participation and health lifestyle and the propor-tion of mediating effect between the two was also calculated.A series of robustness tests were further con-ducted and the fit of the model was checked by structural equation modeling.Results:The mean age of the 4 846 older adults included in this study was(68.20±5.07)years,48.06％of whom were female and 51.94％were male.The KHB results showed that both digital participation and health lifestyle could mediate the relationship between SES and depression of older adults(P＜0.000 1)and the mediating role of health lifestyle accounted for a greater proportion than digital participation.And our study mainly found three potential pathways of SES and depression of older adults,including:(1)SES → digital par-ticipation → health lifestyle → depression,(2)SES → health lifestyle → depression,and(3)SES →depression.Structural equation modeling tests proved the overall fit of the model in this study.Conclu-sion:Our findings showed that in the digital age,in addition to the direct relationship between SES and depression of older adults,and the health lifestyle as a mediator between the relationship,there is also a sequential mediating role of digital participation and health lifestyle to reduce the risk of depression.The findings suggest that we should pay more attention to the probability of the digital divide exacerbating health inequalities and socioeconomic inequalities accumulation in the digital age and promote the co-progress of digital literacy and health literacy among older adults.关键词
