Internet access, support, usage divides, and depressive symptoms among older adults in China: A nationally representative cross-sectional study

This study examines the associations between multiple sub-dimensions of the digital divide, including Internet access, support, usage divides, and depressive symptoms among older adults as well as the potential moderating effects of rural/urban status on these associations in China.Data were obtained from the 2018 China Longitudinal Aging Social Survey, which provided a nationally representative sample of 11,418 participants aged 60 years and older. Multivariate linear regression models were used to analyze the associations between digital divide and depressive symptoms. The moderating role of rural/urban status was tested based on the interaction terms.After controlling for the covariates, access to Internet devices, support for Internet use from family, and using the Internet for communication, entertainment, or as instruments, were found to be significantly associated with a lower level of depressive symptoms (P < 0.05), and compared with no access to the Internet, accessing and using the Internet was significantly related to decreased depressive risks (P < 0.001), whereas access to the Internet with non-use was not statistically significant. Additionally, the associations between multidimensional aspects of the digital divide and depressive symptoms were moderated by rural/urban status, with these associations being significantly stronger among rural older adults (P < 0.05).This study highlights the importance of assessing the associations between digital divide and depressive symptoms from the multidimensional perspectives of access, support, and usage. Policy interventions targeting various aspects of the digital divide should be implemented to ensure active Internet engagement among older adults, especially those living in rural areas.
