Environmental Features Associated With Older Adults' Physical Activity in Different Types of Urban Neighborhoods.

The authors studied associations of nature- and infrastructure-based features with physical activity (PA) in different urban neighborhood types; 848 community-dwelling people aged 75-90 years reported PA and three perceived nature-based destinations and seven infrastructure-based features as outdoor mobility facilitators. Neighborhood type was defined using a geographic information system based on proximity to central service areas and residential density (city center, subcenter, and dense and dispersed areas outside centers). PA was higher in dense areas and the city center.

Hilliness and the Development of Walking Difficulties Among Community-Dwelling Older People.

The objective of this study is to study the associations of objectively defined hilliness with the prevalence and incidence of walking difficulties among community-dwelling older adults, and to explore whether behavioral, health, or socioeconomic factors would fully or partially explain these associations. Baseline interviews ( = 848, 75-90 years) on difficulties in walking 500 m, frequency of moving through the neighborhood, and perceived hilliness as a barrier to outdoor mobility were conducted. Two-year follow-up interviews ( = 551) on difficulties in walking 500 m were conducted among participants without baseline walking difficulties.

Nature as a facilitator for physical activity: Defining relationships between the objective and perceived environment and physical activity among community-dwelling older people.

The aim was to study the correspondence between the objective and perceived environment and to assess their associations with physical activity (PA) in older people. 848 community-dwelling older people aged 75-90 were interviewed on their difficulties in walking 500m, perceiving nature as a facilitator for outdoor mobility, and PA. The presence of water and landscape diversity were objectively assessed inside 500m and 1000m circular buffers around participants' homes.
