网络使用对老年人认知功能的影响研究--基于抑郁和失能的链式中介作用.

Objective To explore the relationship between Internet use and cognitive function in the elderly. Methods Based on the data of China Family Panel Survey (CFPS) in 2020, the IADL scale and the mobile center self 一 rating depression scale were used to measure the disability status and depression status of the elderly. Two 一 column correlation analysis was used to analyze the correlation. This paper constructed a multiple mediating effect model to study the mediating path of the impact of Internet use on the cognitive function of the elderly. Results After controlling for age, gender, marital status, and intergenerational support, the regression results showed that the use of the network had a significant direct impact on the cognitive function of the elderly (仔 =0. 688, £ 二 7. 36, P < 0. 001), and depression and disability significantly affected the cognitive function of the elderly (/3 = - 0. 018,/二 - 2. 696, P <0. 05;/3 = - 0. 114, t - - 4. 83, P < 0. 001). The results of mediating effect analysis showed that the simple mediating effects of depression and disability between Internet use and cognitive function of the elderly were 0. 044 (95% C/: 0. 011 3 - 0. 083 4) and 0. 040 (95% CIz 0. 015 8 - 0. 064 2), respectively, and the chain mediating effect was 0. 006 (95% C/：0. 000 4-0. 013 2). Conclusion Depression and disability status have a mediating effect between whether or not to use the network and the cognitive function of the elderly, and depression and disability have a chain mediating effect in whether or not to use the network to affect the cognitive function of the elderly. With the popularization of the Internet, we should promote the use of the Internet in the elderly, and pay attention to the physical and mental health of the elderly, so as to protect the cognitive function of the elderly and delay or prevent the occurrence of cognitive impairment in the elderly.
