ISLAND Networks Study

Do the same types of socialising have the same dementia risk benefits for everyone?

ISLAND Networks Study

This is a question some ISLAND members have asked, and two ISLAND researchers - Dr Hannah Fair and Dr James Brady – are now trying to answer. Since they could not find adequate answers in the academic literature, they started addressing the question using ISLAND data instead.

In ISLAND surveys, you provide data about four types of social connection that researchers have linked with lower dementia risk. These are connections with friends, connections with family, connections with neighbours, and lower loneliness. Hannah and James have investigated links between actionable social behaviours (things like hosting guests and going to performances) and these types of social connectedness. They looked to see if links are the same for people with different genders, ages, education levels, living situations, and retirement statuses. 

The figure below shows some of the findings and Hannah will present these results at a national conference in Sydney in June. 


Figure legend: a tick shows a link between an actionable social behaviour and a type of social connection that is linked with lower dementia risk. Analyses are adjusted so that we can be more confident that the links we are showing you are real.

Interestingly, the links between how often people host guests in their homes and their social connectedness were strongest among people who live alone. The links between how often people go on social outings and their social connectedness were strongest among people who live more rurally.

To answer more of your questions about socialising for dementia risk reduction, the ISLAND Networks study will launch in next month’s newsletter. This is an optional ISLAND sub-study that will investigate differences between socialising to reduce dementia risk for introverts and extraverts. The ISLAND team is excited about this new project, and we hope that you share our excitement!
