Environmental Characteristics Associated with Older Adults' Social Participation: The Contribution of Sociodemography and Transportation in Metropolitan, Urban, and Rural Areas.

Although social participation fosters older adults' health, little is known about which environmental characteristics are related to greater participation in social activities. The Canadian Community Health Survey ( = 2737), a transportation survey, and multiple secondary data sources were used to identify the environmental characteristics associated with older Quebecers' social participation according to living area. Greater social participation was associated with: (1) a higher concentration of older adults (IRR = 2.172 (95% CI 1.600, 2.948); < 0.001), more kilometers traveled by paratransit (IRR = 1.714 (95% CI 1.286, 2.285); < 0.01), a lack of medical clinics (IRR = 0.730 (95% CI 0.574, 0.930); = 0.01), and more funded home adaptations (IRR = 1.170 (95% CI 1.036, 1.320); = 0.01) in large metropolitan areas; (2) larger paratransit fleets (IRR = 1.368 (95% CI 1.044, 1.791); = 0.02) and a lower density of road intersections (IRR = 0.862 (95% CI 0.756, 0.982); = 0.03) in regular metropolitan areas; (3) less social deprivation (IRR = 1.162 (95% CI 1.025, 1.318); = 0.02) in urban areas; and (4) a higher concentration of older populations (IRR = 2.386 (95% CI 1.817, 3.133); < 0.001) in rural areas. According to these findings, social participation interventions should target the local environment-for example, by providing more social interaction opportunities for older adults living in younger neighborhoods and by improving access to public transportation, especially paratransit.
