Xin Xu , Nanjing Normal Univerisity

Purpose: As centenarians are the most vulnerable social group among the elderly, their quality of life (QoL) is of great significance for the realization of healthy aging and a harmonious society. The purpose of this cross-sectional study was to examine the determinants of QoL of centenarians in Nanjing. Methods: An exploratory factor analysis and structural equation modelling were performed to discuss the complex relationship between physical health, mental health, family support, socioeconomic factors and other dimensions and the quality of life of centenarians. In-depth interviews were conducted. Results: The quality of life (QoL) of centenarians in Nanjing is in the middle level as a whole, and the distribution pattern of the central urban area, the suburbs and the far suburb is decreasing step by step. Four major factors related to QoL emerged from the responses of the participants: (a) psychological support, (b) socioeconomic status, (c) physical health, and (d) sensory ability. Specifically, we found that socioeconomic conditions and physical health have significant effects on QoL, which is manifested in disposable income, retirement wages, cognitive function and leisure social activities. Additionally, psychological support and sensory ability have no significant impact on QoL; however, the latter can improve QoL indirectly by changing the physical health of centenarians. Conclusions: This paper provides a good empirical case for deeply understanding quality of life in centenarians and provides evidence for policies supporting healthy aging and active aging.
