Physical health and cognitive function declines as we age. Aging impacts people’s ability to perform routine tasks, which affects their well-being and sense of independence. One such routine activity that is frequently affected is driving. For older adults, the inability to drive themselves can mean that they become unable to access basic needs or engage in social activities.

In a recent study that was made available online on 29 August 2023 and is all set to be published in volume 176 of Transportation Research in October 2023, researchers from Waseda University, Japan looked at the mobility challenges faced by older adults in the country. They analyzed data from the Japanese Study of Aging and Retirement (JSTAR) survey, using exploratory analysis methods. 

The study found that car ownership among older adults in Japan is strongly related to several positive indicators of well-being. For example, car ownership was associated with higher self-rated health status, greater number of years lived in the current municipality, and better working status. Older adults who owned at least one car experienced a higher level of independence and a greater positive attitude towards giving and receiving help, including running errands, compared to those who did not own a car.

Countries around the world are grappling with challenges caused by an aging population due to falling birth rates. Although the phenomenon is especially acute in Japan, research suggests that other countries will soon follow suit. Therefore, there is an urgent need to develop technologies to improve the quality of life of an aging population and mitigate the impacts of population aging. 

As Associate Professor Andante Hadi Pandyaswargo from the Environmental Research Institute of Waseda University, the lead researcher in the study, notes, "The rate of population ageing and life expectancy in Japan has been increasing. Other countries, including the developing countries, will follow the trend. In fact, the doubling time of the ratio of older adults in the population of some developing countries is faster than that in Japan. The United Nations World Population Prospects 2022 projected that by 2050, the global population of people older than 64 will be more than twice that of children under five. Therefore, countries with an ageing population must quickly adapt and accommodate the changes caused by the growing number of older persons." Besides Pandyaswargo, researchers Tifani Husna Siregar, former Assistant Professor at the School of Political Science and Economics at Waseda University and Hiroshi Onoda, a Professor at the Graduate School of Environment and Energy Engineering at Waseda University, were involved in the study.

Analyzing the findings of this study, the researchers suggest that autonomous driving may play a key role in solving the mobility crisis among older adults. Giving older adults access to autonomous vehicles (AVs) via a car-sharing business model can have several benefits. For instance, it can improve mobility in older adults, reducing the financial costs associated with their transportation. In the long term, introducing the technology to a greater section of the population is likely to increase its adoption.

"Our study found that providing better access and safer mobility, like shared AVs, for older adults in the countryside has the potential to alleviate some mobility concerns that push older adults to relocate to denser cities. Our study also showed that mobility independence relates to self-perceived health and willingness to help others. We hope that nurturing these factors will allow us to halt the unnecessary shrinking of communities and mitigate the mobility challenges of older adults, thereby ensuring their well-being", explains Pandyaswargo.

Shared AVs are a fitting technological solution to the mobility issues facing older Japanese adults, because Japan is a world leader in automobile technology. "The automotive industry is one of Japan's core industries. Therefore, Japan has the potential to set a global example of how automotive technologies can evolve to support the mobility of older adults," Pandyaswargo concludes.

Aging being a reality for all living beings, it is imperative that the challenges we face in our old age are probed for solutions armed with new and emerging technologies. This study attests to this need and shines the light on possible answers to one inescapable question that aging presents.

Yogurt may be the next go-to garlic breath remedy

2023-09-19
COLUMBUS, Ohio – It turns out yogurt may have a previously unknown benefit: eliminating garlic odors. A new study conducted in a lab – with follow-up human breath tests being planned – showed that whole milk plain yogurt prevented almost all of the volatile compounds responsible for garlic’s pungent scent from escaping into the air. Researchers tested the garlic deodorizing capacity of yogurt and its individual components of water, fat and protein to see how each stood up to the stink. Both fat and protein were effective at trapping garlic odors, leading the scientists to suggest high-protein ...

Laser-based ice-core sampling for studying climate change

Laser-based ice-core sampling for studying climate change
2023-09-19
Researchers led by Yuko Motizuki from the Astro-Glaciology Laboratory at the RIKEN Nishina Center in Japan have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution—about 3 times smaller than what is currently available—meaning that it can detect temperature variations that occurred over much smaller periods of time in the past. The new laser melting sampler, or LMS, is expected to help reconstruct continuous annual temperature changes that occurred thousands to hundreds of thousands of years ago, which will ...

Gene required for root hair growth, nitrate foraging found in grasses

Gene required for root hair growth, nitrate foraging found in grasses
2023-09-19
PULLMAN, Wash. -- Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. Identified by a team led by Washington State University researcher Karen Sanguinet, the gene, dubbed “BUZZ,” causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably. “Nitrate ...

Job strain combined with high efforts and low reward doubled men’s heart disease risk

2023-09-19
Research Highlights: Men exposed to stressful working conditions who also felt that they put forth high effort but received low reward had twice the risk of heart disease compared to men who were free of those psychosocial stressors. The impact of job strain and effort-reward imbalance combined was similar to the magnitude of the impact of obesity on the risk of coronary heart disease, in the study of nearly 6,500 white-collar workers in Canada.  Results on how work stress affects women’s heart health were inconclusive.
