Perceived Environmental Barriers and Disability Among Older Adults in the Eastern Himalayan Region of India: A Mixed-Methods Community-Based Study
This mixed-methods study in East Sikkim, India, reveals that perceived disability among older adults is significantly driven not only by chronic illness but also by specific environmental barriers, particularly inadequate public transportation, poor pedestrian infrastructure, and social isolation.

Growing older is a universal human experience, but the way it unfolds depends heavily on where a person lives. While aging naturally brings changes to the body, such as slower movement or the development of chronic conditions like arthritis, a person's ability to live independently is not determined by biology alone. It is shaped by the world around them. If a community has smooth sidewalks, reliable buses, and a strong network of neighbors, an older adult can remain active and engaged even with health challenges. Conversely, if the environment is filled with steep hills, broken paths, and a lack of transportation, those same health challenges can quickly turn into a sense of being disabled. This idea, that disability is a result of the interaction between a person's health and their surroundings, is central to understanding how people age in difficult landscapes.
In the Eastern Himalayan region of India, specifically in the state of Sikkim, the landscape is defined by steep mountains, scattered villages, and heavy rains. Here, the physical terrain itself presents a daily test for older residents. A team of researchers set out to understand how these specific environmental conditions affect the lives of people over sixty. They wanted to know not just how many older adults felt limited in their daily lives, but exactly which parts of their environment were making those limitations worse. By combining personal stories with a large survey, they mapped the invisible barriers that turn a simple trip to the market or a visit to a doctor into a major struggle.
The researchers began by listening to the voices of the people living in these hills. They conducted in-depth conversations with fifteen older adults from both rural villages and the town of Ranipool. These interviews revealed a shared reality: the mountains that were once a source of livelihood and cultural identity had become obstacles. Participants described the exhaustion of climbing long flights of stairs just to leave their homes, the danger of slipping on wet, uneven footpaths, and the anxiety of trying to catch a shared taxi that might be too crowded or might not return. They spoke of feeling isolated as younger family members moved away and of feeling left behind in a world that was increasingly moving online, where they could not read the screens or navigate the apps. These stories painted a vivid picture of five specific hurdles: the rough terrain itself, the lack of safe walking paths, the unreliability of public transport, the loneliness of social isolation, and the frustration of being cut off from digital life.
To see how widespread these feelings were, the researchers then asked 450 older adults across the region to answer a standardized set of questions about their daily functioning. This survey measured how much difficulty they faced in activities like walking, managing their own care, and participating in society. The results were striking. More than sixty percent of the older adults surveyed reported having a perceived disability, meaning they felt significant difficulty in their daily activities. This high rate was not just a reflection of aging or illness; it was deeply tied to the environment. When the researchers analyzed the data, they found that three specific barriers stood out as major drivers of this disability.
First, the lack of reliable public transportation was a powerful factor. Older adults who struggled with getting around by bus or shared taxi were far more likely to report feeling disabled. The uncertainty of whether a ride would be available, or the fear of being stranded without a way home, created a psychological and physical barrier that kept many people at home. Second, the condition of the walking paths played a critical role. When footpaths were steep, slippery, or full of stairs, the simple act of leaving the house became a major physical challenge, directly limiting a person's ability to move freely. Third, social isolation was a significant predictor of disability. Those who felt disconnected from their community and family reported higher levels of functional limitation, suggesting that loneliness and a lack of social engagement can erode a person's sense of capability and independence.
Interestingly, while the steep terrain and the inability to use digital tools were mentioned frequently in the interviews, they did not show up as independent causes of disability in the statistical analysis once other factors were taken into account. This suggests that while the mountains are difficult to live in, the specific design of the walking paths and the availability of transport are the more immediate, modifiable factors that determine whether an older adult feels capable or disabled. The study also confirmed that chronic health conditions, such as arthritis or high blood pressure, were strongly linked to perceived disability, but the environment acted as a multiplier, making those health conditions feel much more limiting than they might in a more accessible setting.
The findings from Sikkim offer a clear message for how we think about aging in mountainous regions. Disability is not an inevitable consequence of getting old or having a chronic illness; it is often a consequence of a world that is not built for the needs of older people. The study suggests that improving the situation does not require a complete overhaul of the landscape, but rather targeted changes to the infrastructure that people use every day. Making walking paths safer with handrails and non-slip surfaces, ensuring that public transport is reliable and accessible, and creating more opportunities for social connection could significantly reduce the feeling of disability among older adults. By addressing these environmental and social factors, communities can support healthy aging, allowing older residents to maintain their independence and dignity even in the most rugged terrain.
