Linking neighborhood green spaces to loneliness among elderly residents—A path analysis of social capital

Population aging poses a central challenge to human society in the 21st century, and a notable correlation has been found between loneliness and age, particularly old age. Loneliness not only substantially impacts the physical and mental well-being of elderly residents but also escalates the burden of old-age care and medical services. As the global trend of aging continues to intensify, tackling population aging and its associated problems has become a common strategic choice of nations worldwide. Grounded in the mediating effect of social capital, this paper explores both the impact and mechanism by which the use of neighborhood green spaces mitigates loneliness among elderly residents. The findings show that, in terms of overall effects, the use of neighborhood green spaces effectively mitigates negative living conditions and psychological problems, thereby fostering the alleviation of loneliness in elderly residents. From a mediating effects perspective, relationship networks, interpersonal trust, and reciprocity norms within social capital play distinct roles in the relationship between the use of neighborhood green spaces and the reduction of loneliness in elderly residents. The direct effect is not statistically significant, which implies a comprehensive mediating role of social capital. In aging neighborhoods, it is imperative to recognize the role of green spaces in promoting elderly well-being and to ensure ample provision of such spaces. Additionally, considering the decline in physical functions among elderly residents, it is crucial to acknowledge their unique sensory thresholds and usage characteristics and compare these to other age groups. Thus, implementing appropriate aging-friendly reforms in green space planning becomes essential to align the allocation of green space resources with the specific needs of elderly residents while catering to the broader population.
