Socio-ecological models emphasize the relationship between the physical environment and physical activity (PA). However, knowledge about this relationship in older adults is limited. Therefore, the present study aims to investigate the relationship between area of residence (urban, semi-urban or rural) and older adults' walking and cycling for transportation and recreation. Additionally, relationships between several physical environmental factors and walking and cycling and possible moderating effects of area of residence, age and gender were studied.

The study examines a hybrid theory containing individual characteristics, resources, and social factors and volunteering of older adults living in Belgium. As scholars have pointed out the underresearched importance of taking the recruitment potential of older adults into account, this study investigates whether potential volunteers, actual volunteers, and non-volunteers in later life are different from each other in terms of individual characteristics (e.g., religiosity), resources (e.g., socioeconomic status), and social factors (e.g., social networks and social roles). Data for the present research were derived from the Belgian Aging Studies, a sample of 31,581 individuals aged 65 to 80 years. Logistic regression analyses indicate that altruistic and religious values, physical health, frequent contact with friends, and providing help to others are important predictors for potential volunteers as well as actual volunteers. Overall, the results indicate important insights for recruitment and retention of older volunteers.

Developing environments responsive to the aspirations of older people has become a major concern for social and public policy. Policies and programs directed at achieving "age-friendly" communities are considered to require a wide range of interventions, including actions at the level of the social and physical environment. This article compares the age-friendly approaches of two European cities, Brussels and Manchester, with a particular focus on policies and initiatives that promote active aging in an urban context. The article examines, first, the demographic, social, and multicultural contexts of Brussels and Manchester; second, the way in which both cities became members of the World Health Organization Global Network of Age-Friendly Cities and Communities; third, similarities and differences in the age-friendly approaches and actions adopted by both cities; and fourth, opportunities and barriers to the implementation of age-friendly policies. The article concludes by discussing the key elements and resources needed to develop age-friendly cities.

Objectives: The advantages of social participation for older adults are well established and have been adopted in aging policy frameworks. However, little is known about the social participation of frail older adults. This research examined the types of social interaction of very frail older adults and the factors influencing this participation. Method: Interviews with 38 very frail older adults were analyzed using Levasseur and colleagues’ (Levasseur, Richard, Gauvin, & Raymond (2010). Inventory and analysis of definitions of social participation found in the aging literature: Proposed taxonomy of social activities. Social Science and Medicine (1982), 71, 2141–2149) taxonomy activity levels of involvement with others. A qualitative hybrid approach with inductive and deductive thematic analyses was used. Results: Participants often disengaged from activities with high involvement with others, preferring activities with less involvement. Low-key participation emerged as an important type of social participation enabling frail older adults to remain engaged in society. Key factors that influenced social participation were functional decline, and the physical (e.g., traffic, the disappearance of local stores) and social environment (e.g., social networks and the presence of meeting places such as community centers). Discussion: Findings advance our knowledge and recognition of the different ways frail older adults participate in society. Despite their frailty, older adults wish to stay socially active. Focusing on the social environment in the frameworks and policies of Age-Friendly Cities and Communities will benefit these individuals.
