Among the participants, 41 middleaged and 26 older adults were identified as exercise addicts. Exercise addiction levels were assessed using the Exercise Addiction Inventory. Health-promoting behaviors were evaluated with the Health-Promoting Behavior Scale, health anxiety with the Health Anxiety Inventory, and death anxiety with the Death Anxiety were significantly higher in the older group compared to the middleaged group (p = .001, p = .041, p = .002, and p = .047, respectively). In the middle-aged group, no significant associations were found between exercise addiction and health-promoting behaviors, health anxiety, or death anxiety (p > .05). In the older group, however, moderate and significant correlations were observed between exercise addiction and health-promoting behaviors (r = 0.454, p = .020) as well as death anxiety (r = 0.425, p = .030). A strong and significant relationship was also identified between exercise addiction and health anxiety in the older group (r = 0.717, p < .001). The findings suggest that exercise addiction in older adults is associated with psychological and behavioral factors, including health anxiety, healthpromoting behaviors, and death anxiety.eninfo:eu-repo/semantics/openAccessAgedAnxietyExerciseDeathAddictiveArticle
