DRIVING IS A PRIVILEGE NOT A RIGHT

Most older drivers aren’t thinking about the road ahead, poll suggests




More than 80% of people over 65 drive at least weekly, but less than half have a plan for a time when they can’t or shouldn’t drive; few have talked to a health professional about it

Note: December 1-5 is Older Driver Safety Awareness Week

 

When today’s older adults learned to drive, they might have heard the Beatles’ “Drive My Car” or Bruce Springsteen’s “Born to Run” on their car radio’s Top 40 station.

Now, 84% of people age 65 and older drive at least once a week, and 62% drive most days, according to a new University of Michigan national poll.

But less than half of these older drivers have made a plan for a time down the road, when changes in their health might make it less safe for them to drive.

Even fewer know they could create a formal plan for stepping away from the driver’s seat when the time comes.

And very few have talked with a health care provider about driving as it relates to their health.

The new report from the U-M National Poll on Healthy Aging involved experts at the U-M Transportation Research Institute, one of the nation’s top centers for mobility studies. The poll is based at the U-M Institute for Healthcare Policy and Innovation and funded by Michigan Medicine, U-M’s academic medical center.

Only 10% of the adults age 65 and older who answered the poll said they haven’t driven in the past six months. 

Among those who had driven at least once in that time, 81% say they are very confident they can drive safely now, though 18% said they are only somewhat confident and 1% were not very confident.

Looking ahead, 51% were only somewhat confident in their ability to drive in the next five years, while 43% were very confident. Another 5% were not confident in their ability to drive in the next five years.

Even with this sense that their driving ability might change as they grow older, about half (54%) of drivers age 65 and over don’t have a plan for when they are no longer able to drive. Women and those over age 75 were more likely to have a plan than men and those age 65 to 74.

“The freedom to drive where you want, when you want, is a critical part of independent living for older adults, and when it’s diminished for any reason it can have profound effects,” said UMTRI researcher RenĂ©e St. Louis, Ph.D., who worked with the poll team and her colleague David W. Eby, Ph.D. to develop the poll and its report. “With most of the Baby Boom generation now in their mid-60s and above, we have millions of older drivers who will need guidance and alternatives as their health begins to affect their ability to drive safely.”

That includes informal support from family and friends, and formal support from public transportation and community-based services, said Eby. 

Already, in the past six months, whether they currently drive or not, 44% of older adults have received rides from friends or family, and 21% have used rideshare services including taxis and private vehicles hailed by apps such as Uber and Lyft. Just 14% used public transportation.

But 5% said ridesharing is not available where they live, and 9% said public transportation isn’t available.

In addition to the national findings, the poll team conducted a Michigan-specific analysis using data from the Michigan Poll on Healthy Aging, with support from the Michigan Health Endowment Fund. A description of the findings, and an interactive data dashboard, are available here

Intersections with health, today and tomorrow

Among those who have been behind the wheel in the last six months, a sizable majority -- 68% -- say they avoid driving under some conditions.

This included 53% who said they avoid driving in bad weather and 48% who avoid driving at night. St. Louis notes that this may be unrelated to age or health and may just be personal preference.

But 14% of drivers age 65 and older said that vision issues affect their ability to drive. Smaller percentages cited temporary or permanent health or mobility issues as having an impact on their driving ability.

Only 6% of older drivers said they had ever talked with a health care provider about their driving.

“This demonstrates a major opportunity for primary care providers, vision care professionals, occupational therapists, pharmacists, and others to discuss the potential impacts of specific conditions or medications on driving ability,” said poll director Jeffrey Kullgren, M.D., M.P.H., M.S., a primary care physician at the VA Ann Arbor Healthcare System and an associate professor of internal medicine at the U-M Medical School. “If an older adult is in the care of a specialist for a chronic condition such as arthritis, diabetes or a neurological condition, or is having an operation, their specialists and surgical teams could also address potential driving impacts proactively.”

Among poll respondents who hadn’t driven in the last six months, the most common reason was that it was no longer safe for them to drive (34%), followed by health issues (29%); respondents could choose more than one answer.

Only 16% of older drivers were familiar with the idea of an advance driving directive, a document that helps a person indicate their driving preferences in case of future health issues, and identify a person to help with decisions about stopping driving.

But once they were given this definition, 70% said it was very or somewhat important to have an ADD.

St. Louis and Eby note that the poll findings have implications for organizations that provide services to older adults, and for local, state and federal policymakers around the country. The findings also have implications for family members and health care providers who could have conversations with older adults about their driving.

Making community transportation services for older adults more available or accessible, and spreading awareness of services that already exist, could help more older adults maintain independence while choosing to leave the driving to someone else, they note.

Driving resources for older adults

The U-M transportation experts also note that vehicle manufacturers have added many features to automobiles in recent years that can increase safety for all drivers.

Older drivers who wish to keep driving as long as possible may want to explore trading in older vehicles for newer ones that have adaptive headlights, backup cameras, crash-avoidance sensors, and adaptive cruise control to help maintain safe following distances automatically. Certain safety features can sometimes be added to older vehicles too. 

They also point to driving resources for older adults and those who interact with them. UMTRI has teamed with the state of Michigan to create an entire site for older drivers, their families and the professionals who provide health care and other services to them. The site provides resources to support older driver safety and mobility, as well as guidance for families and professionals on transitioning away from driving.

Called Safe Drivers, Smart Options, it’s available at https://www.michigan.gov/agingdriver/ and includes a downloadable guide for aging drivers and their families in English, Spanish and Arabic.

The UMTRI team also recommends the MyMobility Plan website and tool offered by the national Centers for Disease Control and Prevention, which is designed to help older adults and people with disabilities plan for their future mobility and avoid motor vehicle crashes and other types of injury-causing situations.

AARP, AAA and other organizations offer driving classes designed for people over 55; the Safe Drivers, Smart Options website links to many of these. AAA also has a Driver Planning agreement to help families plan together for continued, safe mobility.

Public service organizations called Area Agencies on Aging may offer free or low-cost transportation options; find the agency serving any area of the United States here. Local cities, towns and counties as well as regional transportation agencies may offer special transportation services or discounted public transit passes for older adults.

About the poll

The poll findings come from a nationally representative survey conducted by NORC at the University of Chicago for IHPI and administered online and via phone in February 2025 to 2,883 respondents age 50 to 97 from the AmeriSpeak panel. The Michigan-focused analysis includes 1,353 Michigan adults age 50 to 95, including a non-probability oversample. Results are weighted to reflect each respective population.

Tattoos could be a risk factor for melanoma

The state of research on tattoos and cancer

In view of the lack of knowledge concerning the long-term health effects of tattoos, and its position as an under-researched field, researchers at Lund University are examining potential links between tattoos and cancer. The first study, published in spring 2024, showed a possible link between tattoos and lymphoma. A second study was published earlier this year, in which the researchers did not find an association between tattoos and squamous cell carcinoma of the skin.

An increasing number of people are tattooed

Around 20 per cent of all Swedes have been tattooed and for women under 40 the figure is over 40 per cent. Most get their first tattoo between the ages of 18 and 35 but some are even younger, which means almost a lifetime of exposure to tattoo ink. At the same time, the incidence of melanoma has risen considerably over the past 30 years, due to causes such as increased UV radiation, but exposure to chemicals is also a suspected factor. Each year, around 5,000 Swedes are diagnosed with melanoma.

“We don’t know about the long-term health effects of tattoos. We therefore need to clarify if there is a link between tattoo ink and skin cancer,” says Christel Nielsen, associate professor and researcher in epidemiology at Lund University.

Study design

Using the National Cancer Register, the researchers identified 2,880 individuals who have been diagnosed with melanoma between the ages of 20 and 60. These individuals were then each matched with three individuals from the Total Population Register of the same sex and age but without a melanoma diagnosis. The researchers subsequently collected information via questionnaires about whether the participants were tattooed and controlled for other factors such as sun exposure, sun bed use and skin type. Using this study design, they could estimate the risk of melanoma among tattooed individuals in comparison with non-tattooed individuals and also ensure that the results were not due to other factors such as sun exposure and sun bed use.

Results: Increased relative risk observed at group level

"Of the participants who had melanoma, 22 per cent were tattooed, compared with 20 per cent in the control group. But when we took lifestyle factors that might distort the association into account, we saw a 29 per cent increased relative risk among tattooed individuals,” continues Emelie Rietz Liljedahl, associate researcher in toxicology at Lund University.

This applies at group level but not at individual level. The results suggest that tattoos could be a risk factor for melanoma, but further studies are needed before it is possible to talk about a causal link, emphasises Christel Nielsen.

The impact of tattoo ink

When tattoo ink is injected into the skin, the body perceives it as a foreign substance, which means the immune system is activated. The ink pigments are encapsulated by the immune cells, which hold them in place and transport them via lymphatic fluid to the lymph nodes.

“Azo pigments are the most common organic colourants in tattoo ink. This could be a potential risk because we already know that these can break down into harmful chemicals that may cause cancer. This particularly applies for exposure to UV radiation from the sun, sun beds or laser treatments,” says Emelie Rietz Liljedahl.

Regulation of tattoo ink

The tattoo ink market was relatively unregulated until 2022, when an addition to the EU’s chemical legislation (REACH) came into effect and introduced concentration limits for chemicals in tattoo ink. Despite this, market surveillance has shown that inks may still contain toxic chemicals exceeding the maximum limits, comments Emelie Rietz Liljedahl.

“In parallel with the authorities’ continuing work on regulating the market, we need to understand the potential mechanisms through which tattoos may increase the risk of disease. As epidemiologists, our role is to find patterns in the population. Follow-up studies are now needed to examine why these patterns arise,” says Christel Nielsen.

The constantly rising tattoo trend means that the results of the study are more relevant now than ever from a public health perspective. Along with the researchers’ previous findings about a possible link between tattoos and lymphoma – but the absence of an association with squamous-cell carcinoma of the skin -  the new study takes us one step further in understanding how tattoos may affect our health.

Exploring links to autoimmune conditions

“Our results indicate there may be something that happens in the immune system and therefore we are now going on to continue exploring possible links between tattoo exposure and autoimmune conditions, such as psoriasis and thyroid conditions, in which the immune system is also involved,” concludes Christel Nielsen.

 

Thyroid dysfunction during pregnancy may increase autism risk in children





The Endocrine Society





WASHINGTON—Women with persistent thyroid hormone imbalance across pregnancy may be at an increased risk of having children with autismaccording to a new study published in The Journal of Clinical Endocrinology & Metabolism.

Maternal thyroid hormones are essential for fetal neurodevelopment. Gestational thyroid imbalance has been associated with atypical neurodevelopment, including increased risk of autism spectrum disorder (ASD). Autism is a complex neurodevelopmental condition that affects how a person communicates, interacts with others and experiences the world.

“We found that while adequately treated chronic thyroid dysfunction was not associated with increased autism risk in offspring, ongoing imbalance across multiple trimesters was,” said Idan Menashe, Ph.D., of the Ben-Gurion University of the Negev in Beer Sheva, Israel. “These findings underscore the need for routine monitoring and timely adjustment of therapy to maintain normal thyroid hormone levels throughout pregnancy.”

The study followed more than 51,000 births and found that mothers with persistent thyroid hormone imbalance across pregnancy were at an increased risk of having children with autism.

The authors also observed a dose-response pattern, in which the longer the duration of thyroid dysfunction across trimesters, the higher the risk.

Other study authors are Leena Elbedour of the Ben-Gurion University of the Nege; May Weinberg of the Meir Medical Center in Kfar Saba, Israel, and Tel Aviv University in Tel Aviv, Israel; Gal Meiri of the Soroka University Medical Center in Beer-Sheva, Israel, and the Ben-Gurion University of the Negev; and Analya Michaelovski of the Soroka University Medical Center.

No funding was received for this study.

“Maternal Thyroid Hormone Imbalance and Risk of Autism Spectrum Disorder,” was published online, ahead of print.
