The effect of internet use on the health of middle-aged and older adults: evidences from China general social survey

BackgroundAccording to the United Nations classification of aging societies, China is rapidly transitioning into a moderately aging society, facing significant challenges related to population aging. Concurrently, China is actively implementing the Internet Power Strategy and the Internet Plus action plan, which are profoundly transforming the daily lives of individuals, including their health status. However, research on the impact of internet use on the health of middle-aged and older adults has not reached a consensus. This study aims to investigate the effects of internet use on the health of middle-aged and older adults, as well as the mechanisms and heterogeneity of these effects.MethodsThis study utilized data from the China General Social Survey conducted in 2018, which includes a sample of 6470 individuals. Self-rated health, mental health, and objective health were used as key health indicators, with internet use identified as the primary independent variable. The study aims to analyze the impact of internet use on the health status of middle-aged and older adults through the application of an ordered probit model and instrumental variable methods.ResultsThe results indicate that internet use has a significant positive impact on the health of middle-aged and older adults, with significance at the 1% level. This finding has passed a series of robustness tests. Mechanism analysis reveals that information acquisition is a crucial mediating mechanism between internet use and the health of middle-aged and older adults. This suggests that increased internet use enhances information access, thereby improving health outcomes. Furthermore, heterogeneity analysis shows that the impact of internet use on health is more pronounced among individuals living in rural areas, western regions, low-income groups, and those aged under 60, compared to their counterparts in urban areas, eastern regions, higher-income brackets, and those aged 60 and above.ConclusionInternet use can improve the health of middle-aged and older adults. Therefore, government departments, senior universities, communities, and families should collaborate to actively conduct digital skills training for older adults. Additionally, efforts should be accelerated to adapt electronic products to be more elder-friendly, helping older adults overcome the digital divide and thereby reducing health inequalities among middle-aged and older groups.
