Abstract
BACKGROUND: The aging population and changing social trends have led to the concept of successful aging (SA), which promotes a positive view of aging. However, SA is a complex, multidimensional, and interdisciplinary concept, making its definition unclear. This complexity has led to a search for variables associated with SA. This study aimed to determine the most important variables affecting SA. MATERIALS AND METHODS: A systematic review and a two-round Delphi survey were conducted to determine the variables affecting SA. Subsequently, data from a sample of 1465 elderly individuals were collected using the selected factors. Statistical techniques such as Chi-square, backward logistic regression (BLR), and enter methods of the BLR were employed to determine the most significant factors affecting SA, which was assessed according to Rowe and Kahn's definition. RESULTS: Out of 44 factors selected based on expert opinions, 40 were found to be significantly correlated with SA. Following the BLR method, a total of 34 factors showed a statistically significant occurrence chance at P < 0.05. CONCLUSION: The findings of this study are crucial for developing healthcare strategies and health-preventive programs, emphasizing modifiable factors to improve quality of life (QoL) and SA. However, further research is needed to establish the causality of these factors with SA.
