Music may have health benefits for older adults, finds poll

Published

From stress relief and improved mood to keeping minds sharp and connecting to others, a poll of people aged 50 to 80 finds many positives from listening to or making music.

Whether it’s singing in a choir, playing the living room piano, joining in hymns at church, or just whistling along with the radio, a new poll finds that nearly all older adults say music brings them far more than just entertainment.

Three-quarters of people age 50 to 80 say music helps them relieve stress or relax and 65 per cent say it helps their mental health or mood, according to the new results from the University of Michigan National Poll on Healthy Aging. Meanwhile, 60 per cent say they get energised or motivated by music.

Those are just a few of the health-related benefits cited by older adults who answered questions about listening to and making music of all kinds.

Virtually all (98 per cent) said they benefit in at least one health-related way from engaging with music. In addition, 41 per cent say music is very important to them, with another 48 per cent saying it’s somewhat important.

“Music has the power to bring joy and meaning to life. It is woven into the very fabric of existence for all of humankind,” said Joel Howell, M.D., Ph.D., a professor of internal medicine at the U-M Medical School who worked with the poll team.

Music also has tangible effects on a variety of health-related ailments, he adds. “We know that music is associated with positive effects on measures from blood pressure to depression.”

The poll is based at the U-M Institute for Healthcare Policy and Innovation and supported by AARP and Michigan Medicine, the University of Michigan’s academic medical centre. The poll team asked a national sample of adults aged 50 to 80 about their experiences with and feelings toward listening to and making music.

Many older adults reported making music with other people at least occasionally, whether by singing or playing an instrument. In all, eight per cent said they have sung in a choir or other organised group at least a few times in the past year. About eight per cent of all older adults said they play an instrument with other people at least occasionally.

In all, 46 per cent of older adults reported singing at least a few times a week, and 17 per cent said they play a musical instrument at least a few times a year.

Most respondents reported listening to music, with 85 per cent saying they listen to it at least a few times a week, 80 per cent saying they’ve watched musical performances on television or the internet at least a few times in the past year, and 41 per cent saying they had attended live musical performances in person at least a few times in the past year. That latter percentage was higher among those with higher incomes and more education.

The poll shows other differences between groups in music listening habits and health impacts.

Those who said their physical health is fair or poor, and those who say they often feel isolated, were less likely to listen to music every day. Black older adults were more likely than others to have sung in a choir in the past year, and Black and Hispanic older adults were more likely to say that music is very important to them.

“While music doesn’t come up often in older adults’ visits with their usual care providers, perhaps it should,” said poll director Jeffrey Kullgren, M.D., M.P.H., M.S.

“The power of music to connect us, improve mood and energy, or even ease pain (like 7% of respondents said it does for them), means it could be a powerful tool.” Kullgren is a primary care physician at the VA Ann Arbor Healthcare System and associate professor of internal medicine at U-M.

Howell notes that music helps people keep in touch with one another throughout their lifetime. Indeed, 19 per cent of the poll respondents said music is even more important to them now than it was in their youth, and 46 per cent said it’s just as important to them now as then.

With the rising concern about the health effects of loneliness and social isolation among Americans in general, and especially among older adults, the power of music to connect people and support healthy aging should not be underestimated, Howell says. The NPHA has previously reported on trends in loneliness and social isolation in older adults.

“Music is a universal language that has powerful potential to improve wellbeing,” said Sarah Lenz Lock, senior vice president of Policy and Brain Health at AARP and executive director of the Global Council on Brain Health.

“AARP’s own research shows that music can play an important role in healthy aging by improving our moods, fostering social connections and, potentially, enriching our brain health.”

Routine vaccines may protect against dementia, research finds

Published

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.”

Food preservatives linked to increased diabetes and cancer risk, study finds

Published

on

Higher intake of some food preservatives is linked with increased risks of type 2 diabetes and cancer, two studies suggest.

The findings were based on diet and health data from more than 100,000 French adults in the NutriNet-Santé study between 2009 and 2023.

Of 17 preservatives analysed individually, higher consumption of 12 was associated with an increased risk of type 2 diabetes.

Higher intake overall was linked to a 47 per cent increase in incidence.

In the cancer research, several preservatives were linked to higher risk. Potassium sorbate was associated with a 14 per cent higher risk of overall cancer and a 26 per cent higher risk of breast cancer, while sodium nitrite was linked to a 32 per cent higher risk of prostate cancer.

Overall preservative intake was not linked to cancer incidence in the cohort.

Researchers said several compounds could alter immune and inflammatory pathways, possibly triggering cancer development.

Both were observational studies, so they show association rather than cause.

Mathilde Touvier, a coordinator of the diabetes study, said: “This is the first study in the world on the links between preservative additives and the incidence of type 2 diabetes.

“Although the results need to be confirmed, they are consistent with experimental data suggesting the harmful effects of several of these compounds.”

Prof William Gallagher, of University College Dublin, who was not involved with the research, said: “These higher rates of cancer are modest but are significant when taken at a population-based level in terms of potential impact.”

The researchers called on manufacturers to limit unnecessary preservatives and backed advice for consumers to eat fresh, minimally processed foods.

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.”
