Older adults less active in society post-pandemic, finds study

Published

on

A new study of 7,000 people age 55-plus has found they’re staying at home more and skipping restaurants, the gym and other ‘third places’, since the Covid-19 pandemic.

Years after the US began to slowly emerge from mandatory Covid-19 lockdowns, more than half of older adults still spend more time at home and less time socialising in public spaces than they did pre-pandemic, according to new University of Colorado Boulder research. 

Participants cited fear of infection and “more uncomfortable and hostile” social dynamics as key reasons for their retreat from civic life.

“The pandemic is not over for a lot of folks,” said Jessica Finlay, an assistant professor of geography whose findings are revealed in a series of new papers.

“Some people feel left behind.”

The study comes amid what the U.S. Surgeon General recently called an ‘epidemic of loneliness’ in which older adults— especially those who are immune compromised or have disabilities— are particularly vulnerable.

“We found that the pandemic fundamentally altered neighbourhoods, communities and everyday routines among aging Americans and these changes have long-term consequences for their physical, mental, social and cognitive health,” said Finlay.

‘I just can’t go back’

As a health geographer and environmental gerontologist, Finlay studies how social and built environments impact health as we age.

In March 2020 as restaurants, gyms, grocery stores and other gathering places shuttered amid shelter-in-place orders, she immediately wondered what the lasting impacts would be.

Shortly thereafter, she launched the Covid-19 Coping Study with University of Michigan epidemiologist Lindsay Kobayashi. They began their research with a baseline and monthly survey. Since then, nearly 7,000 people over age 55 from all 50 states have participated.

The researchers check in annually, asking open-ended questions about how neighborhouds and relationships have changed, how people spend their time, opinions and experiences of the COVID-19 pandemic, and their physical and mental health.

“We’ve been in the field for some incredibly pivotal moments,” said Finlay, noting that surveys went out shortly after George Floyd was murdered in May 2020 and again after the attack on the US Capitol on January 6, 2021.

Collectively, the results paint a troubling picture in which a substantial portion of the older population remains isolated even after others have moved on.

In one paper published in February in the journal Wellbeing, Space and Society, 60 per cent of respondents said they spend more time in their home while 75 per cent said they dine out less. Some 62 per cent said they visit cultural and arts venues less, and more than half said they attend church or the gym less than before the pandemic.

While that survey was taken two years ago, the most recent survey taken in spring 2023 showed similar trends, with more than half of respondents still reporting that their socialisation and entertainment routines were different than they were pre-pandemic.

In another paper titled “I just can’t go back,” 80 per cent of respondents reported that there are some places they are reluctant to visit in person anymore.

“The thought of going inside a gym with lots of people breathing heavily and sweating is not something I can see myself ever doing again,” said one 72-year-old male.

Those who said they still go to public places like grocery stores reported that they ducked in and out quickly and skipped casual chitchat.

“It’s been tough,” said one 68-year-old female.

“You don’t stop and talk to people anymore.”

Many respondents reported that they were afraid of getting infected with a virus or infecting young or immune-compromised loved ones, and said they felt “irresponsible” for being around a lot of people.

Some reported getting dirty looks or rude comments when wearing masks or asking others to keep their distance— interpersonal exchanges that reinforced their inclination to stay home.

Revitalising human connection

The news is not all bad, stresses Finlay.

At least 10 per cent of older adults report exercising outdoors more frequently since the pandemic, and a small but vocal minority said that their worlds had actually opened up, as more meetings, concerts and classes became available online.

Still, Finlay worries that the loss of spontaneous interactions in what sociologists call “third places” could have serious health consequences.

Previous research shows that a lack of social connection can increase risk of premature death as much as smoking 15 cigarettes a day and exacerbate mental illness and dementia.

“For some older adults who live alone, that brief, unplanned exchange with the butcher or the cashier may be the only friendly smile they see in the day, and they have lost that,” Finlay said.

Societal health is also at risk.

“It is increasingly rare for Americans with differing sociopolitical perspectives to collectively hang out and respectfully converse,” she writes.

Finlay hopes that her work can encourage policymakers to create spaces more amenable to people of all ages who are now more cautious about getting sick – things like outdoor dining spaces, ventilated concert halls or masked or hybrid events.

She also hopes that people will give those still wearing masks or keeping distance some grace.

“It is a privilege to be able to ‘just get over’ the pandemic and many people, for a multitude of reasons, just don’t have that privilege. The world looks different to them now,” she said.

“How can we make it easier for them to re-engage?”

Finding could help identify diabetes patients at risk of vascular damage

Published

The longer someone has type 2 diabetes, the higher their cardiovascular disease risk, and changes in red blood cells may help explain it, new research suggests.

The study found red blood cells from patients with long-term diabetes harmed blood vessel function, while no such effect was seen in those newly diagnosed.

After seven years of follow-up, the blood cells of people initially diagnosed had developed the same harmful properties.

Zhichao Zhou, associate professor at Karolinska Institutet and lead author, said: “What really stands out in our study is that it is not only the presence of type 2 diabetes that matters, but how long you have had the disease.

“It is only after several years that red blood cells develop a harmful effect on blood vessels.”

Researchers at Karolinska Institutet in Sweden studied animals and patients with type 2 diabetes.

They identified microRNA-210, a small RNA that helps regulate gene activity, as a possible early biomarker of cardiovascular risk.

When its levels were restored in red blood cells, blood vessel function improved.

Eftychia Kontidou, doctoral student and first author, said: “If we can identify which patients are at greatest risk before vascular damage has already occurred, we can also become better at preventing complications.”

The researchers are now investigating whether the biomarker can be used in larger population studies.

Routine vaccines may protect against dementia, research finds

Published

on

Routine vaccines for adults may reduce dementia risk, a review of more than 100 million people suggests.

The research found both flu and shingles vaccines were associated with a lower risk in adults aged 50 and over.

The shingles (herpes zoster) jab was linked to a 24 per cent lower risk of any dementia and a 47 per cent lower risk of Alzheimer’s disease.

A joint Italian-Canadian neuroscience review points to a pattern that public health experts say is hard to ignore, suggesting vaccines against common infections may offer long-term protection against the UK’s leading cause of death.

With an ageing population, about two million people are projected to be living with dementia in the UK by 2050.

Prof Sir Andrew Pollard is director of the Oxford Vaccine Group and former chair of the Joint Committee on Vaccination and Immunisation.

He said: “Vaccines for pneumonia, shingles, and influenza in older adults have been shown to reduce the risk of serious infections and hospitalisation caused by these diseases.

“But studies in the past few years have raised the intriguing possibility that vaccination could also provide a welcome reduction in the risk of dementia, a disease which places a huge burden on society and the NHS.”

A separate large-scale randomised trial in Wales compared shingles vaccines Zostavax and Shingrix to address the “healthy user effect”, where people who get vaccinated tend to be more health-conscious. As both groups were vaccinated, this helped control for that bias.

The results showed those receiving the newer Shingrix vaccine had a substantially lower risk of developing dementia over subsequent years.

Dr Maxime Taquet, clinical lecturer in psychiatry at Oxford, who led that study, said: “The size and nature of this study makes these findings convincing, and should motivate further research.”

Weaker body clock linked to increased dementia risk

Published

Weaker, fragmented body clocks are linked to higher dementia risk, new research suggests.

The study also found that people whose activity levels peaked later in the day, rather than earlier, faced a higher risk.

Circadian rhythm is the body’s internal clock, regulating the 24-hour sleep-wake cycle and other processes including hormones, digestion and body temperature.

With a strong rhythm, the body clock aligns well with the 24-hour day, sending clear signals for body functions.

Researchers at UT Southwestern Medical Center in Texas studied 2,183 people with an average age of 79 who did not have dementia.

Participants wore small heart monitors for an average of 12 days to measure rest and activity patterns.

Over an average follow-up of three years, 176 people developed dementia. Those with weaker rhythms had nearly 2.5 times the risk of dementia compared to those with the strongest rhythms.

People whose activity peaked at 2.15pm or later had a 45 per cent increased risk compared to those peaking earlier in the afternoon.

Wendy Wang, the study author, said: “Changes in circadian rhythms happen with ageing, and evidence suggests that circadian rhythm disturbances may be a risk factor for neurodegenerative diseases like dementia.

“Disruptions in circadian rhythms may alter body processes like inflammation, and may interfere with sleep, possibly increasing amyloid plaques linked to dementia, or reducing amyloid clearance from the brain.

“Future studies should examine the potential role of circadian rhythm interventions, such as light therapy or lifestyle changes, to determine if they may help lower a person’s risk of dementia.”
