#Socialisolation

A provocative international study challenges decades of public health messaging by suggesting that loneliness among older adults receiving home care may not be linked to higher mortality. Tracking nearly 400,000 seniors in Canada, Finland, and New Zealand, researchers found that those who reported loneliness were often less likely to die within a year than their non-lonely peers. The results, published in a leading journal of geriatric care, prompt a cautious re-examination of how loneliness is understood in aging policy and everyday care.

In a finding that upends years of public health messaging, a new international study has found that loneliness among older adults receiving home care may actually be associated with longer survival, not premature death as previously feared. The research, which tracked nearly 400,000 seniors in Canada, Finland, and New Zealand, revealed that those who reported feeling lonely were significantly less likely to die within a year than their non-lonely peers—challenging a core assumption at the heart of global aging and public health policy (studyfinds.org).

Recent research is reshaping how Thai health leaders view social isolation. Leading experts say prolonged social isolation can harm health as much as smoking a pack a day, turning loneliness into a global public health priority. The idea, once shocking, is now supported by a growing body of evidence and prompting calls for urgent action to address an epidemic affecting millions.

As social life evolves in the digital era, Thailand’s urbanization and changing household patterns amplify the implications. Thai culture traditionally values family and community, but migration for work, urban living, and the aftershocks of the Covid-19 pandemic mean more people are disconnected from meaningful social contact. This disconnection is now considered a risk factor with potential to shorten life expectancy and reduce well-being, comparable to smoking-related harm.

A wave of recent research is transforming how the world—and Thailand—views the dangers of social isolation. According to leading experts and new studies, living in prolonged social isolation can be as detrimental to human health as smoking a pack of cigarettes each day, elevating the threat to a global public health priority. This comparison, once surprising, is now backed by a growing body of research and calls for urgent public action to address an emerging epidemic affecting millions.

In a groundbreaking study published in Epidemiology and Psychiatric Sciences, researchers have found that individuals who experience social disconnectedness face significantly higher risks of various medical conditions. This study, conducted by Lisbeth Mølgaard Laustsen and colleagues, reveals that loneliness, social isolation, and lack of social support—the three core measures of social disconnectedness—are linked to an increase in illnesses, impacting almost all major health categories (source).

This research is critical for Thai readers who can draw parallels with societal changes in Thailand, where urbanization often leads to reduced family time and a potential for increased social isolation. The study, utilizing data from the Danish National Health Survey, covered 162,604 participants and assessed social connections using tools like the Three-Item Loneliness Scale. The findings indicate that lonely individuals were at greater risk across 11 medical conditions, notably mental disorders and dementia, with loneliness being more influential than social isolation or low social support.

A large study published in Epidemiology and Psychiatric Sciences shows that people who feel socially disconnected face higher risks for many illnesses. The research, led by Lisbeth Mølgaard Laustsen and colleagues, highlights three measures of social disconnection: loneliness, social isolation, and lack of social support. Together, they are linked to more health problems across multiple categories.

For Thai audiences, the findings resonate with evolving urban lifestyles in Thailand, where busier cities can reduce time with family and neighbors. The Danish National Health Survey, which involved more than 162,000 participants, measured social connections with familiar tools like the Three-Item Loneliness Scale. Results indicate that loneliness raises the risk for 11 medical conditions, with mental disorders and dementia showing particularly strong links. Interestingly, loneliness appeared to be a stronger predictor than social isolation or low social support.
