This study aimed to evaluate the current status of traditional Chinese medicine quality of life among older adults in Sichuan Province and explore its influencing factors. In July 2024，quota sampling was conducted in 8 districts（counties）of Sichuan Province using a random number table method，and a total of 1 119 samples were included. The survey was carried out through five dimensions of Chinese medicine quality of life assessment scale（CQ-11D），30 items of Chinese Medicine Questionnaire（CCMQ），Social Support Rate Scale（SSRS）and Health Ecology Model（HEM），and the health level of older adults was evaluated by TCM health utility value. The results showed that age，marital status，educational level，number of chronic diseases， number of adverse childhood experiences，number of children，level of social support，taste preference， medical insurance status，living style，and TCM constitution all significantly affected the TCM quality of life among older adults（P＜0.05）. Multiple linear regression further revealed that there are variations in the effects of different types of chronic diseases，TCM constitution types，and social support dimensions on the traditional Chinese medicine quality of life among the older adults.
