Social connection is a powerful force, and its impact on our health is undeniable. In a world that often feels increasingly disconnected, this recent trip to Carinda by the Coonamble CWA - Evening Branch serves as a heartwarming reminder of the importance of human interaction.
But here's where it gets controversial: new Australian research suggests that the strength of our social connections is not solely determined by our genes. In fact, it's our environment and life experiences that play a more significant role in shaping these connections, especially as we age.
The study, conducted by the Centre for Healthy Brain Ageing (CHeBA) at UNSW Sydney, analyzed data from over 560 twins aged 65 and above. The research, published in the British Journal of Psychiatry, revealed three main types of social connection: spending time with friends and neighbors, interacting with family, and participating in community or religious groups.
And this is the part most people miss: all three types of social connection were found to be only weakly influenced by genetics. In other words, our surroundings and personal experiences have a much greater impact on how we connect with others.
Lead researcher Dr. Samtani expressed encouragement at these findings, stating, "Because social connections are not strongly determined by genes, they are highly modifiable." This means that initiatives and policies aimed at enhancing social engagement can make a real difference in the lives of older adults.
The study also uncovered a fascinating link between social interaction and mental health. Older adults who regularly interacted with friends, neighbors, and community members experienced lower levels of depressive symptoms, both at the beginning of the study and six years later. Even small increases in social interaction were associated with noticeable mental health benefits.
For communities like those in the Western Plains, these findings may not come as a surprise. Social connection is often an integral part of daily life, woven into routine activities and shared experiences.
The trip to Carinda by the Coonamble CWA Evening Branch is a perfect example. Members and friends gathered at the iconic Carinda pub, known for its connection to David Bowie's "Let's Dance" film shoot, to celebrate the end of a successful year. The visit, which came just a year after Carinda's devastating weather event, showcased the resilience and hospitality of small communities.
Co-author Dr. Anne-Nicole Casey emphasized the unique design of the study, which focused on twins. "Looking at twins is particularly powerful because they share genetics and early environments, allowing us to see what is truly unique to individuals. In this study, it became clear that it was people's own life experiences that mattered most."
The study also challenged the notion that social interaction predicts changes in cognitive function. While loneliness and social isolation are known risk factors for dementia, this research did not find strong evidence to support this claim over the six-year period.
As Australia's population ages rapidly, understanding the factors that support healthy ageing becomes increasingly crucial. Depression, anxiety, and dementia remain leading causes of disability worldwide, and social isolation continues to rise, particularly among older Australians.
The findings of this study strengthen the case for community-focused initiatives and services that actively promote connection, especially in regional areas where social interaction is a way of life.
"Encouraging older adults to engage with local groups and stay connected with their neighbors can be a powerful tool in supporting their mental wellbeing," Dr. Samtani concluded.
For towns in the Western Plains, this research serves as a reminder of the practical benefits of strong local networks, contributing not only to community spirit but also to long-term mental health.
