Could 70 be the New 60? Investigating the Association between Internet Use and Subjective Age among Chinese Older Adults

Abstract Objectives The widespread use of the Internet brings both opportunities and challenges for older adults. To understand its potential benefits and drawbacks, we focus on the association between Internet use and multiple indicators of subjective age (threshold age, felt age, and look age) and the underlying mechanisms. Methods A nationally representative sample of older adults aged 60 and over from 3 waves (collected in 2016, 2018, and 2020) of the China Longitudinal Aging Social Survey was used in the analysis. A 3-step random-effect model and mediation analysis were used to examine the relationship between Internet use and subjective age and the mediating roles of volunteering and feeling valued by society. Structural equation modeling with a serial multiple mediation model was conducted for robustness checks. Results The participants generally considered 70 as the threshold for “old age.” Although the mediation analysis did not show a significant indirect effect of Internet use on older adults’ subjective age through volunteering, Internet use was linked with older adults’ subjective age directly and indirectly through feeling valued by society. Compared to moderate Internet users, nonusers felt less valued by society and, therefore, had a younger threshold age and older subjective ages. Heavy Internet users showed a lower level of participation in volunteer activities. Discussion The results support previous theories about the mental and social health benefits of Internet use among older adults. However, Internet use intensity should receive more attention; excessive use may reduce the duration of older adults’ offline social interactions.
