A new report highlighting the role of social connection in reducing dementia risk is prompting renewed calls for older New Zealanders to stay active and engaged in their communities.
The latest World Health Organization (WHO) guidance identifies social isolation as one of the leading modifiable risk factors for dementia, alongside physical inactivity, hearing loss and depression. The report suggests that nearly half of all dementia cases may be preventable through lifestyle changes, reinforcing growing evidence that maintaining strong social connections is vital for healthy ageing.
Responding to the findings, Probus New Zealand says the research confirms what the organisation has promoted for decades — that staying socially connected is not simply beneficial for quality of life but is an important part of protecting long-term health.
The organisation says regular opportunities to connect with others through clubs, outings, shared meals and community activities provide retirees and semi-retirees with an accessible way to remain socially engaged while reducing the risks associated with loneliness and isolation.
The warning comes as New Zealand’s population continues to age. Statistics New Zealand projects that by 2060, one in four New Zealanders will be aged 65 or older, with the over-65 population expected to reach one million as early as 2028. At the same time, Age Concern Auckland research has found that 59 percent of older New Zealanders have experienced loneliness or social isolation, with almost one-third reporting they feel lonely frequently or almost constantly.
Health experts say those trends have significant implications not only for individual wellbeing but also for the wider health system, as social isolation has increasingly been linked to cognitive decline and poorer physical and mental health outcomes.
Probus says its community-based model offers a practical, low-barrier way for older people to remain connected through regular meetings, guest speakers, interest groups and social activities. Membership is open to anyone at or approaching retirement, regardless of background, with no political or religious affiliations.
The organisation hopes the WHO’s latest guidance will encourage more older New Zealanders to view social participation as an important investment in their long-term health, rather than simply a leisure activity.
