Perceived Neighborhood Environment and Changes in Walking for Transportation Among Older Adults: Findings from the EpiFloripa Aging Cohort
This study of older adults in Florianópolis, Brazil, found that more favorable perceptions of neighborhood environmental features, such as sidewalk quality and pedestrian safety, are significantly associated with the maintenance of walking for transportation over a decade, despite an overall decline in positive environmental perceptions during the study period.

As the world's population ages, a quiet but critical question is reshaping how cities are planned: how do we keep older adults moving? Walking is more than just exercise; for many seniors, it is the primary way to get to the grocery store, visit a friend, or see a doctor. This daily movement, known as transportation walking, is vital for maintaining independence and health. However, the decision to walk is not made in a vacuum. It is deeply influenced by the streets, sidewalks, and public spaces right outside a person's front door. If a neighborhood feels unsafe, lacks clear paths, or offers no green spaces, even a willing walker may stay home. Conversely, a well-designed environment can encourage people to keep their legs moving, even as their bodies change with age. Understanding this relationship is essential for building communities that support active aging, particularly in regions where rapid population growth meets complex urban challenges.
In the southern Brazilian city of Florianópolis, researchers set out to track how changes in the neighborhood environment affect the walking habits of older adults over a decade. They followed a group of 737 people, all aged 60 or older, who were part of a long-term study called the EpiFloripa Aging Cohort. The team checked in with these participants three times: first in 2009, then again in 2013, and finally in 2017 and 2019. At each visit, the researchers asked the seniors two main things: how they felt about their neighborhood, and whether they were walking for practical reasons, such as getting to a destination. To measure the neighborhood, they used a questionnaire that asked about specific features like the quality of sidewalks, the presence of parks, the safety of street crossings, and how respectful drivers were of pedestrians. The goal was to see if a shift in how these older adults perceived their surroundings—whether things got better or worse—was linked to whether they kept walking.
The results revealed a story of both decline and resilience. Over the ten-year period, the participants' view of their neighborhood deteriorated in some key areas. The proportion of people who felt their sidewalks were in good shape dropped significantly, falling from about two-thirds of the group to less than half. Similarly, fewer people reported having green spaces, like parks or trees, near their homes. Yet, there were also improvements. More residents noticed pedestrian crosswalks, and the availability of parks and squares for walking increased. However, the feeling that drivers respected these crosswalks was inconsistent; it rose at one point but fell again by the end of the study. Despite these mixed changes in the environment, a remarkable half of the participants managed to keep walking for at least ten minutes a week throughout the entire decade. This was a notable finding, considering that the group was getting older, with the number of people aged 80 and above growing substantially over the study period.
The study found a clear link between how people saw their neighborhood and whether they kept walking. The researchers calculated that for every small improvement in a person's overall positive perception of their neighborhood, their odds of walking for transportation increased. In simpler terms, when older adults felt their neighborhood was safer, more accessible, and better equipped with walking paths, they were more likely to maintain their walking habits. This connection held true even after accounting for factors like age, education, and health conditions. The data suggests that the environment acts as a powerful support system; when the streets feel welcoming, the physical act of walking becomes more feasible, even as the natural challenges of aging set in.
The researchers noted that the pattern of walking was not static. While many participants maintained their walking routine, some stopped, and a smaller group started walking only later in the decade. This indicates that walking for transportation is a dynamic behavior that can change at any stage of life, influenced by both personal circumstances and the changing landscape around them. The fact that so many people lived in the same neighborhood for over a decade suggests that long-term residents are deeply attuned to their surroundings. They notice when a sidewalk cracks or a new park opens, and these changes directly influence their daily choices. The study highlights that urban planning is not just about building infrastructure; it is about maintaining the quality of that infrastructure to support the mobility of an aging population.
Ultimately, the findings from Florianópolis offer a practical lesson for cities everywhere. The research suggests that improving the urban environment—fixing sidewalks, ensuring safe crossings, and creating accessible green spaces—is a direct way to support the independence of older adults. It is not enough to simply build these features; they must be maintained and perceived as safe and usable. When a neighborhood feels like a place where a person can walk with confidence, that person is more likely to keep moving. As the global population continues to age, the quality of the streets and public spaces outside our doors will play an increasingly decisive role in determining who stays active and who stays home.
