Abstract
Background: Although digital exclusion has been widely discussed in relation to healthcare access and digital service use, less is known about its implications for exercise participation among middle-aged and older adults. This study examined how individual digital literacy and area-level digital exclusion jointly shape exercise participation in China.
Methods: Data were drawn from three waves of the China Health and Retirement Longitudinal Study (CHARLS; 2013, 2015, and 2018) and linked to city-year indicators from the China Statistical Yearbook. The analytic sample included 13,085 person-wave observations from 9,201 unique respondents across 111 cities. Exercise participation was measured as a binary indicator of engagement in exercise-oriented physical activity. Individual digital literacy was assessed using a composite index of digital access, internet use, device resources, and digital behaviors. Area-level digital exclusion was measured using a reverse-coded city-year indicator of contextual digital exclusion. Mixed-effects logistic regression models were used to estimate the associations of individual digital literacy and area-level digital exclusion with exercise participation and to test their cross-level interaction.
Results: 37.7% of observations reported exercise participation, increasing from 27.5% in 2013 to 40.3% in 2018. In fully adjusted models, higher individual digital literacy was associated with greater odds of exercise participation (OR = 1.11, 95% CI: 1.022-1.208, p < 0.05). Area-level digital exclusion was negatively associated with exercise participation; although the association was attenuated after adjustment for demographic and socioeconomic characteristics, it remained statistically significant in the fully adjusted model (OR = 0.94, 95% CI: 0.869-0.991, p < 0.05). The interaction between individual digital literacy and area-level digital exclusion was negative and significant (OR = 0.96, 95% CI: 0.929-0.984, p < 0.01), indicating that the positive association between digital literacy and exercise participation was weaker in more digitally excluded cities.
Conclusion: Individual digital literacy was positively associated with exercise participation among middle-aged and older adults in China, whereas area-level digital exclusion weakened this beneficial association. Policies promoting healthy aging should address both older adults' digital literacy and the broader digital exclusion in which they live.
期刊介绍：
Frontiers in Psychology is the largest journal in its field, publishing rigorously peer-reviewed research across the psychological sciences, from clinical research to cognitive science, from perception to consciousness, from imaging studies to human factors, and from animal cognition to social psychology. Field Chief Editor Axel Cleeremans at the Free University of Brussels is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide. The journal publishes the best research across the entire field of psychology. Today, psychological science is becoming increasingly important at all levels of society, from the treatment of clinical disorders to our basic understanding of how the mind works. It is highly interdisciplinary, borrowing questions from philosophy, methods from neuroscience and insights from clinical practice - all in the goal of furthering our grasp of human nature and society, as well as our ability to develop new intervention methods.
