China had an estimated 297 million people aged 60 or older by the end of 2023, and more of daily life now runs through a smartphone. Around this year’s Double Ninth Festival on 18 October 2026, telecoms companies taking part in a national digital ageing-friendly campaign ran classes in several provinces teaching older people to book hospital appointments, pay bills, and make video calls. A new study suggests that, for mood in later life, what matters may be less whether older people are online than how much they do there.
Researchers at the University of Nottingham Ningbo China analysed the China Longitudinal Aging Social Survey, a nationally representative survey of adults aged 60 and over run by Renmin University of China. The study, published in Frontiers in Public Health, followed 5,914 people from 2020 to 2023, of whom 1,972 used the internet at the start. The usage-variety result comes from 1,828 of those users with complete data. Depressive symptoms were scored on a scale of 0 to 18.
The team looked at four sides of the digital divide: no home internet, low smartphone skill, a narrow range of online activities, and problems caused by internet use. Each was measured in 2020 and compared with symptoms in 2023, allowing for earlier mood and factors such as age, education, health, and rural or urban household registration, known as hukou.
Only one stood out. Internet users who did fewer kinds of things online had higher depression scores three years later, while the other three measures showed no clear link. The effect was small, and it barely changed how well the model explained later symptoms.
The researchers then tested four kinds of social connection: contact with family and friends, contact with adult children, closeness to children, and practical help from the community. Only community help played a part. Narrower users later reported that fewer local services were available, such as home visits, help getting to medical appointments, shopping, housework, meals, and day care, and fewer services went with more depressive symptoms.
The authors note that in China these services are increasingly arranged through apps and messaging platforms, so people who do little online may find them harder to reach. The same pattern appeared when the analysis was repeated over an earlier 2018 to 2020 window.
The community link was not the same for everyone. It showed up among older people in cities and those living with others, but was almost absent in rural areas and weaker among empty-nest older people. Urban residents started with more services, so broader online use appeared to add most where support already existed.
The study has clear limits. Everything was self-reported, most measures covered only people who were already online, and every outcome was measured during the COVID-19 pandemic or its aftermath. The pattern mostly reflected stable differences between people rather than changes within the same person, so it cannot show that widening someone’s internet use would lift their mood.
Earlier Psychreg coverage of a South Korean study found that poor housing was linked to more depression among older people living alone, especially in rural areas. The authors argue that digital inclusion schemes should help older people do more online, keep offline ways to reach services, and invest in rural support so that wider online use leads to real help.
