Population aging is a widespread global phenomenon (
1). Aging is defined as a time-related disorder, indicating that over time, due to various factors, a person is exposed to damage that is not properly repaired (
2). According to the World Health Organization, 727 million people aged 65 years and older will be living in 2025, and it is projected that by 2050, the number of elderly individuals will exceed 1.5 billion (
3). The global population of people older than 60 years is expected to increase from 962 million in 2017 to 2.1 billion in 2050 (
4). Consequently, population aging is an inevitable phenomenon in Iran’s future, necessitating the adoption of healthy aging policies.
Aging is a sensitive period of human life, and addressing the issues and needs of this stage is a social necessity. Given the specific needs of older adults, attention to health-promoting behaviors, which have often been neglected, is critically important (
5). Although aging does not necessarily equate to declining health or increased disability (
6), health problems among older adults, particularly mental health issues, become more pronounced alongside demographic shifts. Elderly individuals with limited or negative social relationships may develop thoughts that lead them to avoid contact with others, reinforcing negative self-perceptions. These stresses can trigger unpleasant emotions such as anxiety and depression, as well as major and minor physical illnesses (
7). One of the key challenges many older adults face is communicating with new people and expanding their social circles (
8). Thus, social isolation among older adults is a growing concern (
9).
A substantial number of older adults are at risk of social isolation and social constraint due to broad changes in the social structure of societies. Evidence suggests that individuals with fewer social relationships are more likely to experience mental disorders, especially depression, suicidal behavior, alcoholism, addiction, reduced health and life expectancy, decreased quality of life and life satisfaction, increased disability, and a higher likelihood of hospitalization or admission to elderly care centers (
10). These risks are particularly important for older adults given their specific physical, mental, and social conditions. Enhancing social capital among older adults may contribute to reducing healthcare expenditures (
11). Moreover, given the relatively high prevalence of cardiovascular disease risk factors in older women and men, comprehensive planning is required to identify underlying causes and implement continuous education on lifestyle modifications, such as proper nutrition, exercise, and regular physical activity, as effective strategies to reduce cardiovascular burden (
12). Studies indicate that cardiovascular risk factors, including obesity, hypertension, physical inactivity, and smoking, are significantly prevalent among older adults; therefore, screening, risk factor control, and health promotion efforts are strongly recommended (
13).
Successful aging can be achieved by maintaining social participation and social status. To promote public health, it is essential to consider social capital, given its substantial impact on individuals’ lives (
14). Maintaining communication with others is crucial for achieving successful aging, which comprises health, longevity, and happiness, and this goal is more attainable through increased social capital (
15). Studies have demonstrated that attention to social determinants of health, including social capital and social participation, plays a significant role in promoting the health of older adults (
16). Social capital is directly associated with reduced mortality, improved health, greater happiness, and poverty reduction (
17).
Social capital is a relatively new and evolving concept in social research, yet it is deeply rooted in human social relations. It is defined as the funds of social life, including networks, norms, and social trust, that enable individuals to act collectively and effectively toward common goals (
18). Social capital encompasses relationships, shared values, and trust among individuals and groups, facilitating collaboration and the achievement of collective objectives; it is inherently multidimensional (
19). It primarily derives from relationships with family, neighbors, religious communities, and broader society, and it contributes to both mental well-being and physical health (
20). Social capital constitutes a resource available to individuals through membership in specific groups or networks and is personally realized through social networks or structures. Robert Putnam, in his theory of social capital, argues that communication and social networks significantly influence individual and social outcomes, including health behaviors. Putnam conceptualizes social capital as comprising features of social organization, such as networks, norms, and trust, that enable coordination and cooperation for mutual benefit (
21). The core components of social capital therefore include mutual trust, support, cooperation, and reciprocal relations among members of a society. Given the specific challenges of old age and the protective role of social capital, investigating this form of capital in later life is more necessary than ever.
As Iran is beginning to experience population aging, it is imperative to address health-related issues among older adults. Identifying the health status of older adults is the first step toward health promotion and the ultimate goal of successful aging. Given the undeniable importance of social capital in achieving life satisfaction, quality of life, public health, and successful aging, the need to examine this variable in the elderly population is increasingly evident. Moreover, given the scarcity of studies on this topic in Iran, particularly in Kermanshah, more extensive research in this area is warranted.
Studying social capital within a hospital setting is particularly important for several reasons. Hospitals serve as a critical interface at which elderly individuals, often with heightened health and social vulnerabilities, interact with the healthcare system. Social capital, encompassing trust, networks, and social support, can directly influence health-seeking behaviors, adherence to medical advice, and the ability to navigate complex healthcare processes (
22). Furthermore, robust social capital is associated with better postdischarge outcomes, including reduced readmission rates, improved recovery from acute illnesses, and more effective management of chronic conditions common among older adults (
23). For older adults, a hospital visit itself can represent a period of heightened need for social and instrumental support, making it a strategic context in which to assess social resources that may buffer against health declines. Therefore, investigating social capital in this setting allows for the identification of modifiable factors that can be integrated into holistic care plans, ultimately aiming to enhance both immediate healthcare experiences and long-term health trajectories in the aging population.
Therefore, this study was conducted to determine social capital among elderly individuals visiting Imam Ali Hospital in Kermanshah.
