• The prevalence of SA was 71.1% in Korean adults aged 70 and older, and those with SA significantly decreased by 7.8% over 4 years. • Older adults who preserved SA (54%) maintained the fulfillment of the criteria for SA, and the proportion of successfully maintaining indicators such as chronic diseases, employment, and volunteer activities was relatively low. • There was a significant increase in older adults with declined physical function or experiencing depressive symptoms between 2016 and 2020. • SA of older adults in response to unexpected social transition requires strengthening the physical and psychological functions of older adults and improvement of social engagement. This study aims to determine the prevalence of successful aging (SA) and examine the association of changes in the indicators of SA and variations in SA status between 2016 and 2020. The study included 548 participants recruited for the Korean Frailty and Aging Cohort Study (KFACS). Compared to participants who achieved SA in 2016 ( N = 393, 71.7%), the number of older adults with SA decreased by 7.8% in 2020. Among older adults preserving SA (SA→SA group, 54%), there were relatively small numbers of older adults who successfully maintained indicators, including chronic diseases (no→no, 9.5%), employment (yes→yes, 12.2%), and volunteer activities (yes→yes, 2.9%). Our findings suggest that interventions to strengthen the physical and psychological function of older adults are needed, and social support needs to be guaranteed to improve social engagement for older adults.
