RESUMO
Although positive attitudes toward own aging (ATOA) have been shown to be associated with higher levels of quality of life (QoL) among older adults, the potential interrelationship between ATOA and QoL has not been fully explored. A sample of 2129 older adults aged 60 and above who participated in the three waves of the Chinese longitudinal healthy longevity survey was used. QoL was measured using three indicators, including self-rated health, loneliness, and life satisfaction. The cross-lagged analysis results showed that the bidirectional association between ATOA and QoL was not significant, while positive ATOA predicted better self-rated health, higher life satisfaction, and less loneliness. And there are no gender or age differences in the above relationships. In addition, economic status, sleep quality, and activity participation were common influences on self-rated health, life satisfaction, and loneliness, as well as important factors affecting ATOA. Several variables, such as demographic characteristics, health behaviors, and health status, also influenced QoL and ATOA. Measures to promote positive ATOA can help improve QoL. In addition, emphasis should be placed on improving economic status, sleep quality, and activity participation levels to enhance QoL and ATOA in older adults, with appropriate interventions targeting other factors affecting QoL and ATOA.
