Positive health, social participation and health equity: Important issues for aging adults
Positive health focuses on why some people are healthy and others in the same situation are not [
5], i.e., what creates health and strengthens the effectiveness of clinical and population interventions [
6]. Measures of positive health include outcomes such as life satisfaction, functional status and performance. Such a salutogenic focus operationalizes the content, values, and principles of the Ottawa Charter for Health Promotion [
7]. Health promotion is the process of enabling people to increase control over and improve their health, and focuses on promoting self-esteem and coping abilities of individuals and communities, ultimately leading to less dependence on professional services [
8]. Among positive health strategies and inspired by health promotion, the World Health Organization (WHO) Active Ageing Policy Framework defines active ageing as ‘
the process of optimizing opportunities for health, participation and security in order to enhance quality of life as people age’ [
9]. Adopted by the WHO in the late 1990s, this framework recognizes the factors that affect how individuals and populations age [
10], and the right to equal opportunities and treatment in all aspects of life as people grow older, including participation in the political process and community life [
9]. Health, the labour market, employment, education, urban design and social policies supporting active ageing can potentially result in fewer disabilities associated with chronic diseases or premature deaths, more people participating actively in community life and enjoying a positive quality of life, and lower costs for medical treatment and care services. Active ageing policies and programs encourage personal responsibility, age-friendly environments and intergenerational solidarity [
9].
As one of the key dimensions of health and active aging,
social participation has been found to be a determinant of many health and quality of life outcomes such as mortality [
11], morbidity [
12], hospitalisation [
13], and functional autonomy [
14]. While greater social participation has been demonstrated to be positively associated with these outcomes, social isolation, at the other end of the continuum, has been shown to have detrimental health consequences. For example, isolated older adults were found to be at greater risk of being rehospitalised, even when controlling for health status [
11]. Social participation can be defined as a person’s involvement in activities that provide interactions with others in the community [
15] and results from the interaction between personal and environmental factors [
16]. Known to protect against cognitive decline among community-dwelling older persons [
17], participating in society is primarily for the person’s own sake and cannot be accomplished by someone else without losing its benefits (e.g., pleasure from being with others) [
18]. From a population perspective, older helpers and volunteers are a resource for their families, communities and economies in supportive and enabling living environments [
19]. Social participation has been shown to be closely related to mobility in the community [
20] and home [
21], and to decline as a result of the ‘normal’ aging process [
22,
23]. Facilitated when the abilities of the person and the environment are optimised [
24], social participation can be enhanced by population [
25] and individual [
26] interventions.
Health equity is the absence of unfair systems and policies that cause health inequalities, i.e., presence of groups of people that are at greater risk of experiencing poorer overall health than the general population [
27]. Health outcomes are stratified by social contexts [
28], which engender differential exposure and vulnerability to health-damaging conditions, and disparity in economic and social consequences [
29]. Health inequalities emerge from the accumulation of exposures in different degrees and from everyday life situations that generate threat, fright and coping difficulties [
29]. The main groups of factors that have been identified as playing an important part in explaining health inequalities are
material factors (economic and physical environments, including housing conditions) [
30],
psychosocial stressors (e.g., negative events, stressful circumstances, lack of support), and
behavioural factors (passive or active smoking [
31], diet, alcohol consumption, physical exercise, etc.) [
29]. Tackling health inequalities involves addressing the unequal distribution of these health determinants [
32], such as income and social status, education and literacy, physical environments, social supports and coping skills, healthy behaviours, access to health services [
27]. Health equity seeks to reduce inequalities by increasing access to opportunities and conditions conducive to health for all by 1) improving living and working conditions, 2) tackling the inequitable distribution of power, money and resources, 3) measuring and understanding equity and assessing the impact of action, and 4) enhancing health promotion and disease prevention policies. Health inequalities might be reduced by, for example, reinforcing factors that might lessen susceptibility to health effects from inequitable exposures using various means including empowerment, social support and community development, or strengthening policies that reproduce contextual factors such as social capital that might modify the health effects of poverty [
28]. Although policies and interventions have been developed to achieve these goals, a better understanding of how they promote health and well-being in all aging adults is needed.
Age-friendly communities: A promising population intervention to enhance positive health, social participation and health equity in aging
In an effort to shape active aging as a lifelong process and take advantage of the potential that older people represent for humanity, the WHO challenged worldwide communities to become more age-friendly [
19]. In Canada, all provinces have initiated age-friendly community processes [
33] and approximately 800 communities have launched age-friendly initiatives. An age-friendly community encourages active aging by optimizing opportunities for health, participation and security by adapting its structures and services to be accessible to and inclusive of older people with varying needs and capacities [
19]. Eight issues and concerns have been voiced by older people as characteristics of an age-friendly community:
1) outdoor spaces and buildings, 2) transportation, 3) housing, 4) opportunities for social participation, 5) respect and social inclusion, 6) civic participation and employment, 7) communication and information, and 8) community support and health services.
Taking these health-promoting issues into consideration, and in accordance with the theoretical perspective of Glass and Balfour [
34], neighbourhood
facilitators (i.e., helpful environmental factors) can enable greater positive health, social participation and health equity [
34,
35]. For example, neighbourhood characteristics such as living close to services [
36,
37] like grocery stores, health services, public transportation, banking services and social clubs, have been shown to be important in performing activities to meet daily needs. A neighbourhood perceived as friendly and supportive has also been reported to be independently associated with an increased likelihood of participating in social activities [
38]. In contrast, personal capabilities might be challenged or exceeded by environmental
obstacles (e.g., physical barriers, inaccessibility of services and amenities, social stress, and resource inadequacy), which can impact positive health, social participation and health equity. Indeed, individuals with disabilities need support from the social environment [
34,
39] and accessibility in the physical neighbourhood environment [
34,
39‐
42] to help them live in the community [
34,
43,
44]. Moreover, the closure of nearby services has been shown to be worrisome [
37], especially for women considering the prospect of not being able to drive or concerned about declining mobility [
36].
As highlighted in a recent scoping study, mobility and social participation in older adults have been demonstrated to be positively associated with indicators of most age-friendly characteristics, i.e., with 1) proximity to resources and recreational facilities, 2) social support, 3) having a car or driver’s license, 4) public transportation, and 5) neighbourhood security, and negatively associated with 6) poor user-friendliness of the walking environment, and 7) neighbourhood insecurity [
45]. Nevertheless, based on an analysis of cross-sectional data [
46], environmental variables associated with social participation differed according to area. Indeed, only the social participation of older adults living in metropolitan areas was associated with transit and quality of the social network, whereas social participation in rural areas was correlated with the presence of children living in the neighbourhood and more years lived in the dwelling. Having a driver’s license and greater proximity or accessibility to resources were associated with social participation in all areas [
46]. In addition to be associated with social participation, resources, transportation and social networks are among age-friendly issues.
How age-friendly communities foster positive health, social participation and health equity: What is needed for a better understanding?
Although age-friendly communities are believed to be a promising way to help older adults lead healthy and active lives and stay involved in their communities, it is essential to know which and how age-friendly key components of communities (i.e., policies, services and structures related to physical and social environments of communities) foster positive health, social participation and health equity [
47]. Previous research focused mainly on comparing age-friendly approaches [
48] or assessment [
49], detecting factors that assist communities in or hinder them from becoming age-friendly [
50], explaining the collaborative partnership conditions and factors that foster implementation effectiveness [
51], as well as identifying priorities for actions [
52]. This research provided valuable information on most common projects that, for example in Manitoba, were related to outdoor spaces, buildings, communications and activities (e.g., walking groups, contacting isolated older adults) [
52]. However, projects vary across communities and change over time. Rural communities’ ability to become age-friendly was influenced by contextual factors such as size, location, demographic composition, ability to secure investments, and leadership [
50]. Communities mostly assess their success by considering the level of community involvement, surveys, program attendance and number of classes taught, as well as incorporating the needs of older adults in organisations’ and agencies’ strategic planning [
53]. Moreover, research has shown differences in rural versus urban communities’ trajectory and timeline for improving age-friendliness. On the one hand, some rural communities made quick progress with small projects but had more difficulty tackling larger projects than urban centres [
52]. The presence of strong social ties and sense of place were found to be among their strengths, whereas poor infrastructure, widely dispersed population, large geographic distance, and aging as a result of out-migration were among their challenges [
52]. Urban centres, on the other hand, may need more time in the early stages but, by building on existing infrastructures and processes, may be able to address larger projects more easily [
52]. Finally, another cross-sectional study found that a superior rating of age-friendliness was associated with a higher percentage of residents aged 65 or older [
54]. The communities that were identified as having the lowest age-friendliness were small communities located within a census metropolitan area and remote communities in the far north of Manitoba. Future studies are needed to determine whether age-friendly initiatives benefit all older adults and specifically their health [
55].
To our knowledge, only one US [
56] and three Canadian empirical studies, two in Manitoba [
57,
58] and one in the province of Quebec [
59], examined the influences of age-friendly communities on health-related outcomes. Using an exploratory factor analysis of items from a sample of 1376 urban older Americans, six factors were identified as being associated with demographic characteristics and self-rated health: 1) access to business and leisure, 2) social interaction, 3) access to health care, 4) neighbourhood problems, 5) social support, and 6) community engagement [
56]. One Canadian study used photovoice with 30 participants in one urban and three rural age-friendly communities in Manitoba and found that to promote health and well-being and facilitate independent living, it is important to ensure that older adults have access to a broad range of community supports such as provision of services, counselling, congregate meals, volunteer drivers and a medical equipment-lending program [
57]. For example, congregate meals are beneficial to those who live alone and have difficulty purchasing groceries, by providing not only needed nutrients but also opportunities for social interaction. Moreover, waiting lists for medical and long-term care are a key concern, and rural areas present unique challenges, with their transportation difficulties and greater proportion of older adults [
57]. Since transportation links older adults not only with health services but also with community life including local businesses, services and opportunities for social participation, the absence of affordable and accessible transportation may create barriers to health services, contribute to social isolation and decrease health equity. Finally, in addition to transportation, multiple aspects of older adults’ lives, including housing, social environment, activities and volunteering, and community supports and health services are influenced by affordability [
57]. The limitations of this study were the relatively small number and homogeneity of the participants, and its possible selection bias towards healthier and younger individuals living in only four age-friendly communities in Manitoba.
Another cross-sectional study involved a needs assessment process in 29 communities beginning age-friendly initiatives in rural Manitoba, where 593 younger and older adults completed a survey [
58]. The survey focused on the presence or absence of
age-friendly key components in seven domains targeted by the WHO [
19] (physical environment, housing options, social environment, opportunities for participation, community supports and healthcare services, transportation options, communication and information), generating a total score and for each domain, as well as life satisfaction and self-rated health. The results indicated that a higher rating of the community’s age-friendliness was related to greater life satisfaction and self-rated health [
58]. All of the seven age-friendly domains except housing were positively related to life satisfaction. For self-rated health, significant relationships emerged with physical and social environment, opportunities for participation, and transportation options [
58]. Age-friendly domains’ relationship with life satisfaction and self-rated health were restricted primarily to older adults. None of the community characteristics [population size, % of residents 1) aged 65 or older, and 2) with less than high school education, and median income] were related to life satisfaction and self-rated health, nor was degree of rurality [
58]. However, as the responses were made immediately after the age-friendly survey, life satisfaction and self-rated answers might have been influenced by that study. Moreover, limited information was available on participants’ sociodemographic characteristics, reducing the possibility to consider intrapersonal factors in the analyses. Participants were also from only one Canadian province (Manitoba), were not randomly selected and might not be representative of their communities. Finally, the communities involved were assessing their needs, i.e., in an early phase of the age-friendly community and prior to the implementation of initiatives.
Lastly, a realistic evaluation study is currently underway to identify how characteristics of four contrasted age-friendly communities in the province of Quebec (i.e. a city of over 100,000 inhabitants, a group of villages around a rural municipality, a rural municipality and a municipality in the suburbs of Montreal) influence social determinants of health and foster health equity [
59]. Preliminary results show that these cases use a community development approach, with strong civic participation from older adults, intersectoral collaboration, governance, leadership, development of capacities of communities and individuals, and concrete actions involving older adults. Their supralocal consulting modes and intersectoral partnerships help to sustainably change access, supply or service organisation to improve the living conditions identified by older adults as priorities [
59]. However, this study focuses on sectoral stakeholders and does not examine health issues of older adults living in these communities.
Despite the contribution of these studies, little is known about age-friendly key components of communities and how they foster positive health, social participation and health equity. Comparisons of communities according to health outcomes would also be important [
58]. In addition, qualitative studies are needed for an in-depth exploration of how age-friendly initiatives impact older residents living in diverse settings [
52]. A health equity lens is also needed to ensure that age-friendly communities not only improve health but also foster health equity. As age-friendly domains cannot be treated in isolation from intrapersonal factors (e.g., functional status) and other levels of influence (e.g., policy environment), the ecological premises underlying age-friendly communities also support the need for a holistic and interdisciplinary approach [
60]. Two ecological models of health, one focusing on multiple aspects of the neighbourhood environment [
61,
62] and one specific to age-friendly communities, have been developed recently to reduce communication difficulties and stimulate collaboration across disciplines (e.g., public health, rehabilitation and gerontology). Moreover, recent advances have been made in the conceptualisation (definition) and operationalisation (measurement) of positive health [
5], social participation [
63] and health equity [
27]. Such efforts were required to enable optimal future research on the impact of age-friendly communities as a population intervention. It is thus timely, innovative and essential to conduct more research to
better understand which and how key components of age-friendly communities best foster positive health, social participation and health equity in aging Canadians. Specifically, the research aims to:
1)
Describe and compare age-friendly key components of communities across Canada
2)
Identify key components best associated with positive health, social participation and health equity of aging adults
3)
Explore how these key components foster positive health, social participation and health equity.
As part of the second objective, the correlates of positive health and social participation will be examined with a health equity lens. More specifically, the relationships between key components, positive health and social participation will be examined according to various individual-level characteristics (Table
1). Environmental characteristics will also be considered to quantify social and geographical inequalities (Table
1). The choice of these individual and environmental correlates is based on the literature, including one scoping review [
45]. Age-friendly key components that enhanced both positive health and social participation of aging adults in these subgroups will be identified as they might foster health equity.
